Every year, 8 to 10 million metric tons of plastic end up in our oceans, harming marine life and ecosystems. It’s not just an environmental issue; it’s affecting our health and economies too. The problem is so big that no single country can solve it alone.

Key Players (as of early 2025)

1. High Ambition Coalition (HAC): 85 countries pushing for strong, binding commitments.

2. Business Coalition: 250+ businesses, including IKEA, Nestlé, and Unilever, supporting an ambitious treaty.

3. “Like-minded group”: Countries like Russia, Saudi Arabia, China, and Iran, focusing more on waste management than production cuts.

4. United States: Not part of the HAC, hesitant on production control measures.

5. France, Rwanda and Mexico: Leading a group of 95 “willing countries” supporting legally-binding provisions to phase out harmful plastic products and chemicals.

Hopeful Outcomes

1. Reducing virgin plastic production

2. Eliminating harmful chemicals in plastics

3. Promoting reuse systems and better product design

4. Improving waste management globally

5. Creating a truly circular economy for plastics

Timeline

– March 2022: UN resolution to create the treaty

– 2022-2024: Initial negotiation rounds

– May 2025 (tentative): Final negotiation round (INC-5.2)

– End of 2025: Target date for finalizing the treaty

– 2040: Ambitious goal to end plastic pollution

Remember, this treaty isn’t just about banning plastic straws. It’s aiming to revolutionize how we produce, use, and dispose of plastics. It’s like going on a global plastic diet – we’re not giving up plastics entirely, but we’re trying to make healthier choices for our planet.

As we head into the crucial 2025 negotiations, the world is watching to see if global leaders can put aside their differences and create a treaty that truly tackles the plastic crisis. Will we see a game-changing agreement, or will it be watered down by competing interests? Only time will tell, but one thing’s for sure – the outcome will shape our relationship with plastics for decades to come.

RanMarine’s WasteShark and MegaShark are perfectly positioned to help deliver on the Global Plastics Treaty’s ambitious goals. These innovative aquatic drones directly tackle plastic pollution in waterways, a key focus of the treaty. The WasteShark, capable of collecting up to 500 kg of debris daily, has already proven its worth in urban waterways and marinas. Its bigger sibling, the MegaShark, launched in 2024, takes this concept further with a capacity to hold 880 liters of waste. Both can operate remotely and emission-free, aligning with the treaty’s emphasis on innovative, sustainable solutions. Moreover, their data collection capabilities support the research and monitoring aspects crucial to the treaty’s success. RanMarine’s technology stands out as a practical, scalable solution that could play a pivotal role in achieving the treaty’s objectives.

So, next time you’re sipping your drink through a paper straw, know that you’re part of a worldwide movement. The Global Plastics Treaty might just be the biggest cleanup effort in human history – and it’s happening right now!

Fungus breaks down ocean plastic

A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers from, among others, NIOZ published their results in the scientific journal Science of the Total Environment. They expect that many more plastic degrading fungi are living in deeper parts of the ocean.

The fungus Parengyodontium album lives together with other marine microbes in thin layers on plastic litter in the ocean. Marine microbiologists from the Royal Netherlands Institute for Sea Research (NIOZ) discovered that the fungus is capable of breaking down particles of the plastic polyethylene (PE), the most abundant of all plastics that have ended up in the ocean. The NIOZ researchers cooperated with colleagues from Utrecht University, the Ocean Cleanup Foundation and research institutes in Paris, Copenhagen and St Gallen, Switzerland. The finding allows the fungus to join a very short list of plastic-degrading marine fungi: only four species have been found to date. A larger number of bacteria was already known to be able to degrade plastic.

Follow the degradation process accurately

The researchers went to find the plastic degrading microbes in the hotspots of plastic pollution in the North Pacific Ocean. From the plastic litter collected, they isolated the marine fungus by growing it in the laboratory, on special plastics that contain labelled carbon. Lead author Annika Vaksmaa of NIOZ: “These so-called 13C isotopes remain traceable in the food chain. It is like a tag that enables us to follow where the carbon goes. We can then trace it in the degradation products.”

Vaksmaa is thrilled about the new finding: “What makes this research scientifically outstanding, is that we can quantify the degradation process.” In the laboratory, Vaksmaa and her team observed that the breakdown of PE by P. album occurs at a rate of about 0.05 per cent per day. “Our measurements also showed that the fungus doesn’t use much of the carbon coming from the PE when breaking it down. Most of the PE that P. album uses is converted into carbon dioxide, which the fungus excretes again.” AltThough CO2 is a greenhouse gas, this process is not something that might pose a new problem: the amount released by fungi is the same as the low amount humans release while breathing.

Only under the influence of UV

The presence of sunlight is essential for the fungus to use PE as an energy source, the researchers found. Vaksmaa: “In the lab, P. album only breaks down PE that has been exposed to UV-light at least for a short period of time. That means that in the ocean, the fungus can only degrade plastic that has been floating near the surface initially,” explains Vaksmaa. “It was already known that UV-light breaks down plastic by itself mechanically, but our results show that it also facilitates the biological plastic breakdown by marine fungi.”

Other fungi out there

As a large amount of different plastics sink into deeper layers before it is exposed to sunlight, P.album will not be able to break them all down. Vaksmaa expects that there are other, yet unknown, fungi out there that are degrading plastic as well, in deeper parts of the ocean. “Marine fungi can break down complex materials made of carbon. There are numerous amounts of marine fungi, so it is likely that in addition to the four species identified so far, other species also contribute to plastic degradation. There are still many questions about the dynamics of how plastic degradation takes place in deeper layers,” says Vaksmaa.

Plastic soup

Finding plastic-degrading organisms is urgent. Every year, humans produce more than 400 billion kilograms of plastic, and this is expected to have at least triple by the year 2060. Much of the plastic waste ends up in the sea: from the poles to the tropics, it floats around in surface waters, reaches greater depths at sea and eventually falls down on the seafloor.

Vaksmaa: “Large amounts of plastics end up in subtropical gyres, ring-shaped currents in oceans in which seawater is almost stationary. That means once the plastic has been carried there, it gets trapped there. Some 80 million kilograms of floating plastic have already accumulated in the North Pacific Subtropical Gyre in the Pacific Ocean alone, which is only one of the six large gyres worldwide.”

RanMarine is dedicated to capturing floating waste and plastics from the water before they break down into microplastics.

Smart Cities Embrace Autonomous Surface Vessels for Waterway Clean-up

Axis Global Comms – United Arab Emirates

Across the globe, urban centers designated as “smart cities” are increasingly turning to cutting-edge technologies to address the complex challenges of urban waterway management. Among the most promising innovations is the Autonomous Surface Vessel (ASV), a robotic solution poised to revolutionize how cities maintain the health and cleanliness of their canals, rivers, harbors, and other aquatic environments.

ASVs represent a significant leap forward from traditional waterway maintenance methods, which are often costly, labor-intensive, and environmentally disruptive. These vessels are designed to autonomously navigate urban waterways, removing floating debris, controlling unwanted biomass, and contributing to the overall aesthetic appeal of the cityscape. Their compact size and remarkable maneuverability allow them to access areas that are difficult or impossible for larger boats or manual cleaning crews to reach, such as narrow canals, under bridges, and around moored vessels.

Beyond their impressive cleaning capabilities, ASVs offer a wide range of potential benefits for smart city initiatives. One of the most exciting possibilities is their capacity to serve as mobile platforms for environmental monitoring. Equipped with a suite of sensors, these vessels could collect valuable data on water quality parameters such as temperature, pH and dissolved oxygen. This information would provide city managers and environmental agencies with a more comprehensive and up-to-date understanding of the health of their waterways, enabling them to make more informed decisions about pollution control, resource management, and infrastructure investments.

The likely ability to gather detailed water quality information using ASVs represents a significant step forward in urban environmental management. This potential for data collection aligns perfectly with the smart city ethos of leveraging technology to improve decision-making and optimize resource allocation.

In addition to their environmental and data-gathering benefits, ASVs offer economic advantages for cities. Their autonomous operation reduces the need for human labor, leading to lower operating costs and greater efficiency. ASVs can operate near continuously, well beyond the standard 9-to-five model, allowing for consistent waterway maintenance without the constraints of traditional work schedules. This continuous operation can be particularly valuable in cities with busy waterways that require constant attention.

Furthermore, the use of ASVs can enhance the image of a city as a forward-thinking and environmentally responsible destination. Clean, healthy waterways contribute to the overall quality of life for residents and visitors alike, boosting tourism, property values, and civic pride. By investing in ASV technology, smart cities can demonstrate their commitment to sustainability and innovation, attracting businesses, talent, and investment.

The adoption of ASVs is still in its initial stages, but the potential benefits are clear. As technology advances and cities continue to embrace the smart city model, ASVs are likely to play an increasingly important role in urban waterway management. These robotic vessels represent a promising solution for creating cleaner, healthier, and more sustainable urban environments for generations to come.

As cities grapple with the challenges of urbanization, climate change, and environmental degradation, the need for innovative solutions has never been greater. ASVs offer a unique combination of environmental, economic, and social benefits, making them a valuable asset for any smart city seeking to improve the health and sustainability of its waterways. These vessels are not just cleaning up trash; they are helping to build a brighter, more sustainable future for urban communities around the world.

OUR WATERWAYS WITHOUT PLASTIC.

Interview by Up!Rotterdam / Rotterdam Innovation City

The mission of RanMarine is to develop advanced technology specifically designed for cleaning up pollution, organic waste, and debris in waterways. Additionally, water quality is monitored, allowing proactive measures to be taken to improve water quality.

Founder Richard Hardiman: “The idea for RanMarine arose in 2016 when I saw a few guys pulling plastic out of the water with a fishing net in a harbor in South Africa. I thought: this can surely be made easier. I literally sketched the idea for what is now the WasteShark on a napkin.”

By removing plastic from the water in time while it’s still floating, we try to reduce the risk of it breaking down into microplastics” Richard Hardiman, RanMarine

Since 2020, Richard and his family have moved to Rotterdam. “I tried to start my company in South Africa, but there are many more challenges there than in The Netherlands. I had done business in Rotterdam before, so I knew the city. When I read about a startup program I could participate in, I didn’t hesitate to sign up and travel to Rotterdam. The Netherlands has a very large volume of water, so I immediately thought: this is the place to bring my idea to life. Moreover, Rotterdam, with all its maritime expertise, is the ideal hotspot for my company.”

RanMarine has developed several autonomous surface vessels, commonly known as water drones. Operating on technology similar to that of robot vacuum cleaners, these aquatic drones come in various sizes and are tailored to different environments. Compact versions are suitable for rivers and canals, even between moored boats, while larger models are designed for ports and lakes. The flagship product is the WasteShark, a catamaran-style vessel that can operate both remotely or autonomously and is equipped with a waste collection bin between the floats.

Richard: “Actually, there should be a WasteShark everywhere because it’s often only purchased when waste is visible on the water. It’s better to anticipate, because if you remove waste and plastics in time, you do so before it breaks down into microplastics.”

Richard has big plans for the future. “I also see a collaboration with Hebo. Together, we are working on the development of an emission-free vessel for rapid response in removing small oil spills from waterways. Every day, I am feeling happy with my work. It’s a great feeling to be involved in something good. I see that reflected in my colleagues too. For example, Robotic Engineers can work anywhere, but they also choose to work for an organization like RanMarine that makes the world a better place.”

“Without Rotterdam, I would never have achieved what I have now. There is so much talent here. It’s truly a city of action! As a good Rotterdam saying goes: Actions speak louder than words. The TU Delft is nearby, while the port with all its knowledge is within easy reach. UpRotterdam has been immensely helpful in the process. With their network, they directed me to the right people and organizations. Sometimes I talk to friends in South Africa about my experiences starting my business, and they don’t believe me when I say that I received needed supported during the process. As a Dutch person, you might not fully realize how well things are organized here. 

To all new entrepreneurs, I would say: don’t be afraid to fail. There are plenty of opportunities in the Netherlands. Just take the risk, there is always a safety net here.”

Algae-based microrobots able to clean up plastic waste

Swarms of iron-clad algae have been built to sweep through bodies of water to collect elusive bits of micro- and nanoplastics. Meet the Microrobots!

Imagine you are but a piece of plastic, adrift in an endless ocean — a mere remnant of a once larger structure, the origin of which you do not recall. You are the product of many, many years of natural erosion, and yet you, invisible to the human eye, persist.

Moved by the ocean’s whims, your fate is likely to be consumed by whichever organism stumbles upon you first. But suddenly, a shadow looms overhead, and much to your disbelief, it is no fish or squid, but a green sphere covered in bits of black iron, moving towards you at unnatural speeds. You feel yourself being pulled towards it, and as you approach, you realize it’s also covered in many others like you.

Albeit a dramatic representation for effect, it hints at a remarkable development made possible by a team of researchers at the Central European Institute of Technology (CEITEC) at Brno University of Technology.

By decorating green algae cells with ever so tiny particles of black iron oxide — also known as magnetite — the team created magnetic algae robots that can be controlled from a distance to sift the most elusive of plastics from the waters.

A mess to clean up

Let’s face it: we love plastics. They are cheap, flexible, and moldable, while also being very durable and light. This makes them extremely convenient materials for endless applications, and thus, their current widespread use.

However, these very advantages are also highly detrimental from an ecological perspective. Their rising levels of production, combined with their characteristic resistance to natural degradation, have led to huge quantities of plastic waste that will stay in the environment for anywhere between a few decades to several centuries.

Throughout this entire time, plastics in aquatic environments will break down into minute fragments that are categorized into microplastics (smaller than 5 mm) and nanoplastics (smaller than 1000 nm). These fragments are then ingested by fish and other aquatic organisms, causing physical harm, problems in digestion and reproduction, and potentially death.

They can also collect other pollutants present in the water, such as heavy metals and organic contaminants. These plastics and the contaminants they carry are transferred up the food chain, and scientists are still beginning to study what effects, if any, this might have on humans in the long run.

To try and clean this mess and mitigate the persistence of micro- and nanoplastics in the environment, researchers have been developing all sorts of solutions. Unfortunately, these generally suffer from being too complex or expensive to carry out, or simply weren’t efficient enough.

This is where the robots come in.

Magnetic algae robots

To better target these tiny plastics, a team of researchers at CEITEC came up with the idea of creating equally tiny janitors that they could control. These tiny robots are not like the conventional mechanical machines we’re used to but are themselves micro/nano-sized particles made up of a combination of various functional materials.

“I was thinking I could find one cheap and mass-producible material to replace expensive metals,” said Xia Peng, a researcher and Ph.D. student at CEITEC, and primary author of the current study published in the Advanced Functional Materials journal. “Then algae cells just came to my mind.”

Dubbing them “magnetic algae robots” or MARs, Xia and her team decorated cells of Chlorella vulgaris (a species of green microalgae) with eco-friendly magnetite nanoparticles, which enable the MARs to be manipulated using an external magnetic field. These algae are not only biodegradable, but they are also easy and cheap to mass produce.

Another advantage is that their surface is riddled with chemical groups called carboxylic acids, which carry a negative electrostatic charge. “The surface charge of MARs is negative due to the presence of [carboxylic acid] groups, while the surface charge of the micro/nanoplastics selected is positive, which promotes the electrostatic attraction of targeted micro/nanoplastics, allowing for their capture and removal,” explained Xia.

The negatively charged algae attract positively charged micro/nanoplastics and keep them “glued” to themselves. This is also how the magnetite nanoparticles, which are positively charged, can be attached to the surface of the algae cells for remote magnetic control without requiring any complex processing.

Initial tests

For their tests, the team used a positively charged fluorescent variant of the ubiquitous plastic polystyrene, whose size varied from 2 μm to 50 nm. This fluorescent form glows under specific experimental conditions and enables the team to measure the quantity of plastic removed from water samples by the MARs, including deionized, tap, rain, and lake water.

They added MARs to these contaminated water samples, sent them on predefined trajectories under magnetic guidance — picking up the polystyrene in their path — and then examined the treated samples by comparing their levels of fluorescence intensity before and after the treatment.

“The most significant findings,” declared Xia, “were the successful capture of micro/nanoplastics […] with high removal efficiency for both nanoplastics (92%) and microplastics (70%).”

Not only that, but MARs could be recycled for further use by washing off the captured plastics. Small amounts of their magnetite coating were also washed away, but they still preserved around 80% efficiency for capturing nanoplastics and 54% for microplastics even after five cycles of washing, after which they could simply don a fresh coat of magnetite and be back to full potency.

“MARs could potentially be tested in salt water since their magnetically driven movement is not affected by salinity,” mentioned Xia. “However, the study is still in the initial stage.

“It’s important to further study the biodegradability and potential long-term environmental effects of these nanoparticles to ensure they do not lead to toxicity issues.” But things seem promising on that front.

“Generally, iron oxide magnetic nanoparticles are considered biocompatible and have been already employed in various environmental and biomedical applications,” said Xia. “In addition, in our case, the nanoparticles can be easily collected by a permanent magnet at the end of the process, ensuring that no particles are left to contaminate the water.”

Further development

Not all plastics polluting our waters are positively charged, though. Many are negatively charged under normal aquatic conditions, meaning MARs wouldn’t be able to capture them through their current built-in electrostatic interactions.

“Our system on the initial experimental stage is kind of limited because MARs only could capture positively charged plastics,” said Xia. “In the future, I also would like to develop a system that can capture negatively charged micro/nanoplastics. But now, I need time to think about it.

“I think the utilization of natural sources, like algae cells, to accomplish specific tasks is highly promising. I believe if developed enough, MARs would be sufficient to deal with the recovery of micro/nanoplastics.

“It’s possible they could complement other methods rather than entirely replace them. This may include their combination with other functional nanoparticles, which can allow MARs to perform other tasks.”

Robot shark

‘Robot shark’ from startup RanMarine collects waste from the canals of Zaandam: Rotterdam company is aiming for ’round of millions’ to conquer the US

Frequent visitors to the Zaandam city center will have already seen him: the so-called ‘Veulvreter’. Here, in the Gedempte Gracht, a small white boat sails once a week with an insatiable hunger for waste. Floating cans, chip trays, PET bottles: this mini-catamaran eats everything that we humans would rather lose than be rich.

The ‘Veulvreter’, as it is called in Zaandam, is actually called WasteShark. It is a creation of the Rotterdam company RanMarine (in full: RanMarine Technology). After a charge, the electrically powered boat can search the water for six hours for waste, according to a pre-programmed zigzagging pattern. As a result, the ‘robot shark’ can remove up to 500 kilograms of waste from the water per day, according to the startup.

Zaanstad was the second Dutch municipality to launch the WasteShark in December, after Dordrecht had previously conducted a successful trial with the device. It saves time for employees of the municipal waste service in Zaandam, as they no longer have to fiddle with fishing nets to retrieve discarded cans from the canal.

Esther Lokhorst stands bent over one of her robot sharks in an old industrial building on a business park in the Rotterdam industrial area Nieuw Methesse. The interior can be described as a potpourri of wires and chips. A team of four young men works on the hardware and Lokhorst, as operational director, keeps an eye on things.

A little further in the open air we find a small water bath, which was installed here by RanMarine. Even though the sun is shining seductively this Wednesday afternoon, people are not supposed to take a dip in it. The only bather allowed is the WasteShark, which Lokhorst and her team test here after every refinement of the technique.

Sensor-equipped drones

The boats are in fact drones equipped with GPS and two sensors. The sensors measure the water quality and depth and forward this information to an online portal of RanMarine. “If, for example, dredging is required, customers immediately gain insight into how deep the soil is,” says Lokhorst.

Her company supplies floating drones that work completely autonomously, but also robot boats that you can control remotely. The robot boat can not only grab plastic waste from the water, but also duckweed. The company is currently investigating in Helsinki whether it is also possible to rid the water of blue-green algae.

No, the robot sharks are not a danger to passing birds, Lokhorst says when asked when we take a seat in a deserted, industrial-looking company canteen. “The boats only sail three kilometers per hour,” says the director. “In our five years of existence, we have never caught a bird or even a fish.”

RanMarine has so far sold more than fifty of these types of boats to 25 customers, says Lokhorst. Many of those customers come from abroad. For example, robot boats from the startup are sailing in the port of Houston, in Dallas and in Plymouth in the UK. The company has customers worldwide: from South Africa to South Korea and from Nigeria to Ireland.

Typical customers are government institutions and water boards, but theme parks are also part of the regular customer base. For example, RanMarine supplies its robot boats to Disney and Universal parks in Florida, among others. “America is a very important market for us,” says Lokhorst. “We are therefore now setting up an American division. We already have employees in the US and want to expand considerably.”

In time, this should result in an American office, says Lokhorst when asked. When, she can’t say yet. “For the time being, we will keep production and development here in Rotterdam. If we scale up considerably in the US, we will also start an assembly department there.”

In the Netherlands, Zaandam and Dordrecht are currently the only municipalities to which RanMarine supplies its aquadrones. It sometimes turns out to be quite complicated to hook up with municipalities. “The municipality is not always responsible for cleaning up waste. Some municipalities outsource this to cleaning companies.”

Lokhorst does state that its sales team is busy hooking up more Dutch municipalities. RanMarine even expects to start a project in the Wadden Sea soon.

Film WALL-E provided inspiration

Lokhorst is not the founder of RanMarine. The company was founded in 2016 by South African Richard Hardiman, who worked as a radio DJ and journalist in a previous life.

Hardiman came up with the idea of ​​the garbage-eating robot shark when he was sitting on a terrace in Cape Town and saw people using a net to remove dirt from the water. There had to be an easier way, Hardiman thought. His mind wandered off to the film WALL-E, in which the leading role is played by a futuristic robot that collects and compresses waste.

A little further on, the bearded man in his forties is having a video call with a colleague from the US. Hardiman has been living in the Netherlands since 2020, where he saw more opportunities to succeed with his startup plan than in South Africa. He participated in a growth program of PortXL, a company affiliated with the port of Rotterdam, for which Lokhorst worked. She joined the then fledgling startup in 2017.

Now, six years later, the company already employs 23 people. RanMarine has been profitable since 2021, according to Lokhorst. The company does not share profit and turnover figures. From the most recent summary profit and loss account that the company filed with the Chamber of Commerce (KvK), it can be concluded that RamMarine closed 2021 with a positive equity capital of more than 7 tons.

RanMarine raised an unknown amount of growth financing twice in its existence. According to Lokhorst, a “serious round of millions” is planned for April. With the upcoming millions, RanMarine hopes to be able to grow faster, especially in the US. The company is also investing in the development of larger aquadrones and robot boats that can extract oil from the water.

Rapid growth also seems to be necessary. In 2019, RanMarine was the first party to market an aquadrone. The market is now busier, with competitors in France, China and the US. Nevertheless, Lokhorst does not see a major threat in this: “The market is large enough for several parties. The positive thing about more competition is that this technique will become better known as a way to remove rubbish from the water.”

The shark that collects waste and data

If you look carefully, staring at the water, you will see it: a shark with a huge open mouth. But no fish, plankton or unsuspecting swimmers disappear into this shark’s mouth: the WasteShark catches plastic and other waste. RanMarine’s promising prototype has developed into a mature water robot that cleans water worldwide. Creator Richard Hardiman: ‘I am an inventor, I enjoy turning ideas into actual solutions.’

The idea for the WasteShark originated in South Africa, where Hardiman comes from. ‘I saw two people fishing rubbish out of the water with a fishing net. I thought: surely there must be a different and better way of doing that? A product that can clean up waste without anyone being present. Around the same time, I became a father and developed an interest in sustainability. I wanted to do something good, also in terms of work. And that’s how the idea for the WasteShark was born. I have an engineering background so I started building. In 2016 I came into contact with the PortXL programme that allowed me to develop my idea as part of my newly established startup RanMarine.’

Water robot

Hardiman ended up at RDM Rotterdam, where he continued to develop his shark: ‘The WasteShark is a mini-water robot that floats and can navigate autonomously. It scours the surface of the water for plastic, waste and pollution and other things that do not belong in the water. The WasteShark collects it in its ‘open mouth’ and brings it to the shore. The smart shark can also pick up natural material that impacts water quality, such as duckweed, algae and aquatic plants. In addition, the WasteShark collects data on water quality. For example, it can monitor whether outboard water is suitable for swimming.’

Practical

How large and heavy is the shark? Hardiman lists the specifications: ‘The WasteShark is controlled via 4G, has a range of 3 kilometres, reaches a speed of 3 kilometres per hour and can swim for about 6 hours. The water robot is 1.57 metres long, 1.09 metres wide, 52 centimetres high and weighs 75 kilos. Very manageable in other words.’

Easy to use

There are several people and organisations whose models retrieve waste from the water. How is WasteShark different from other solutions? Hardiman: ‘It is simple, elegant and efficient. It is emission-free and does not result in any other pollution in the water, and it is easy to deploy. That was also our aim. We wanted to design a tool that collects as much waste as possible in a simple and manageable way, and can be used easily and by as many people as possible. If you have a fairly large car, you can even transport it in the boot. So it’s user-friendly for a wide audience.’

Millions of sharks

How does Hardiman see the future? ‘I am not against plastic, it is a convenient product. But we do have a huge mountain of plastic waste entering the environment. It’s all about how to recycle plastic even better. We can make great strides in that and the WasteShark can contribute. My dream is to have millions of WasteSharks active all over the world. Not only to collect waste, but also to collect data. We need to know what is in our water and not just what is floating on it. Using that data, we can learn how to improve and maintain the quality of the water!’

Springboard

What does Rotterdam mean to Hardiman? ‘My original idea was to return to Cape Town, but the Port of Rotterdam is a springboard to the world of robotics and engineering. And there’s a strong network of companies here committed to sustainability worldwide. This will allow us to improve the WasteShark even further and expand its distribution. I started out on my own and now we have grown into a company with 25 people, thanks to Rotterdam. I am glad I stayed, because without the Port of Rotterdam, RanMarine would not be here!’

WasteSharks – Taking a bite out of water pollution

The state of the planet, and particularly our bodies of water, is becoming of greater concern every day. Some estimates are that one million plastic bottles are sold every minute across the globe, many of these ending up in waterways.

One man who is making a massive difference in that regard is Cape Town’s own, founder of RanMarine and the WasteShark – a marine vessel designed to both clear unwanted material from inland and near-coastal water, and to collect water quality data from the marine environment – that’s now operational in 12 countries around the world, including South Africa.

“The purpose of the WasteShark is to remove waste, litter (plastics) and harmful algae from the surface of the water. The idea is that, very much like a small autonomous vacuum cleaner… this machine can operate in a similar fashion, cleaning the water constantly,” explains Hardiman.

“Our purpose is to develop technology to make our world a more liveable place and ease the pressure humans are adding to our fragile water resources and ecosystems”

“The WasteShark and our developing platforms are part of the greater vision of making collection of waste and pollution in water more efficient, less costly and ultimately less harmful than current methods used,” he adds.

1. When was the WaterShark invented?
The WasteShark was invented as a concept in 2013 but wasn’t developed into a first prototype until 2015; in 2016 the founder Richard Hardiman was invited to enter a maritime accelerator in Rotterdam, the Netherlands where he received funding to develop the first version of the WasteShark we know today.

2. What was the motivation behind its invention?
The original idea came about when Richard saw how marine litter was then being cleaned by water authorities, using small boats and pool nets to remove the litter. Richard thought he could design and come up with a more effective way to remove waste from water using drones. The original motivation was a desire for greater efficiency but also led Richard into the environmental space where he saw just how effective new technology could be in helping our planet.

3. Where is the WaterShark being used? Where did it start off and how has it grown over the years?
The idea and concept were developed in Cape Town, South Africa and the very first prototype was built and tested there. Subsequently Richard moved the business to the Netherlands to develop the product and business further.  Since 2016 drones now operate in the EU, Ireland, the UK, South Korea, India, Australia and the USA amongst others.

4. What purpose does it serve? How does it function?
The purpose of the WasteShark is to remove waste, litter (plastics) and harmful algae from the surface of the water.  The idea is that very much like a small autonomous vacuum cleaner you may have in your house, this machine can operate in a similar fashion, cleaning the water constantly.  RanMarine has developed two versions of the product, one that is remote controlled and an operator can remain on the quayside while cleaning and capturing waste. The second version is an autonomous robot that can be set to clean an area without human intervention and return with waste once it is full. It uses onboard lidar as collision avoidance and collects water quality data as it goes using sensors mounted onboard.

5. How does the product omit emissions?
The WasteShark uses batteries to operate so it does not emit any emissions while it is in use – like a battery-powered car, the WasteShark can be operated up to 10 hours a day on a single charge.

6. Are there any plans to further develop the WasteShark, and what do those plans look like?
RanMarine is launching a larger version in the next six months capable of removing one ton of waste in a single load, this has been developed over the last few years and will be on sale in the middle of the year; we are also developing a docking station which houses up to five WasteSharks at a time, empties their baskets automatically and recharges them making it a total autonomous solution where humans are only required for oversight.

SA Sailing in partnership with World Sailing are committed to reducing waste and together have released a cobranded Sustainability Education Programme for sailing clubs and parents as part of the 2030 Agenda of Sailing’s commitment to global sustainability.

RanMarine Technology

With the WasteShark, RanMarine Technology from Richard Hardiman supplies a floating robot that tackles the plastic soup like a nautical Roomba.

What: Drone that removes plastic from the water
Who: Richard Hardiman (46)
Challenges: Plastic soup
Since: 2016
Employees: 18
Funding: 2.3 million euros (VCs and subsidy) Website : ranmarine.io

The idea came to him when Richard Hardiman saw a few people scooping plastic from a boat on a terrace in Cape Town. That had to be more efficient than with a scoop net, right?

At the time, the Briton Hardiman had already completed a career as a journalist and radio DJ and was studying business in South Africa. On a napkin he drew a robot that, just like Wall-E in the delightful animated film, collected plastic from the water.

Auquadrone with lidar

That was almost ten years ago. But the idea did not leave him. After his studies, Hardiman and a partner decided to create a startup around his WasteShark: RanMarine Technology. In a great place: Rotterdam, where more startups around the theme of sea and ports are being set up.

In recent years, the aquadrone has been developed into a smart and – thanks to lidar – self-propelled system. Like the familiar Roomba for the home, the electric sharks sail autonomously, soon from a docking station where they can recharge themselves and dump their dirt.

‘We have launched an emission-free electrical alternative that the government and water boards can use, instead of older technology that mainly runs on fossil fuels. We challenge water managers to do better with pollution,” says Hardiman.

Clean up and collect data

Where Boyan Slat looks for the open sea, where he wants to remove the gigantic floating clumps of plastic soup, Hardiman limits himself to inland waterways. In ports and canals, the autonomous surface vessels (ASV) also seek out the smallest corners to tackle dirt there.

But make no mistake: every day they consume up to 500 kilos of plastic or organic floating junk that does not end up in the ocean. Along the way, they also monitor water quality and temperature, collecting a wealth of data for their boss.

“ We chose to build drones with a very specific use case,” says Hardiman. ‘That sets us apart. We are also making it easy for our customers to use robots, enabling them to clean more, emit less carbon dioxide, and collect important water quality data at the same time.”

Innovation Award at CES

The WasteSharks are now several dozen and sail their rounds all over the world: from Denmark to Singapore and from England (Canary Wharf) to the port of Houston. Disney, among others, uses the aquadrone in their American resorts.

They can also suck up more than just plastic. They are now also removing blue-green algae from the water in Helsinki, stuff that is suitable for processing in cosmetics and animal feed. Hardiman won an innovation award with it at the CES tech fair .

There are plenty of plans to scale up. In North America, Hardiman wants to open branches, and he is also looking at new products. The WasteShark should have a big brother, the MegaShark, with a capacity of 100 kilos per day, and a version that specializes in oil spills, the OilShark. RanMarine is looking for new funding for this. A stock exchange listing in the US could provide for this in the future.
