Expert Consensus

An ultra cost-effective way to prevent plastic from entering the oceans, with an elegant and reliable technology.

Snapshot

The Problem

11 million tons of plastic waste enters the ocean every year, killing millions of animals annually. 80% of ocean plastic pollution comes from land-based sources, and rivers are the main way that plastic gets transported out to sea.

The Solution

"Trashbooms" are floating barriers that stop plastic waste in rivers before it reaches the ocean.

Impact to Date

  • Prevented over 412 Tons of plastic from entering the oceans (as of Dec 2022)

  • Designed the first open-source walkable river trash boom system

  • Expanded river “trashbooms” into multiple countries throughout Asia

Big Goal

"Clean the most polluted rivers in the world"

Mission

"Pull ocean-bound plastic from the most polluting rivers to save the ocean"

Will it actually make a difference?

Plastic Fischer is focused in a region that feeds plastic into one of the top 10 most polluting rivers in the world (Ganges River, India), and is employing a proven and measurable solution. 80% of ocean plastic pollution comes from land-based sources, and rivers are the main way that this plastic gets transported out to sea.

Each donation goes to the manufacturing and maintenance of river barrier systems that help develop waste management in local regions, and prevent ocean-bound plastic from reaching the ocean. In a word, yes!

How is the donation used?

Each dollar removes 1 kilogram or 2.2 lbs of ocean-bound plastic from highly polluting rivers (primarily in Asia) and ensures proper processing so that it never returns to the water or to landfills again.

DDC's Favorites

  • 3L approach: Locally sourced, low-tech & low-cost! This means more dollars going to removing plastic.

  • Plastic Fischer open-sources their river plastic solutions.

  • Rivers account for an estimated 80% of ocean plastic!

  • Plastic Fischer processes every kg of plastic removed to ensure it never returns to a river/the ocean ever again!

Key Drawbacks

  • Plastic Fischer is still a relatively young organization, working with a new technology that has not been proven over an extended period of time.

  • Although they are growing quickly, Plastic Fischer's scale is still relatively small compared to the scale of the problem. Their model is highly scalable, but it will take time to grow and clean more of the 1,800 rivers that transport the most ocean-bound plastic.

  • Plastic Fischer stems the flow of waste plastic to the oceans, but it alone won't stop the source of the plastic problem -- system-wide change is also needed (e.g. by governments and large corporations) to prevent production of single-use plastic in the first place.

  • We see an opportunity for Plastic Fischer to grow their partnerships and collaborations, to work with others who are cleaning plastic and advocating for change in the plastic problem.

Plastic Fischer focuses on simplicity and efficiency by avoiding moving parts and using the power of the river whenever possible. The solutions have no frills, but get the job done. The 3L approach uses local, low-cost and low-tech solutions to tackle the problem quickly at scale and involve the local communities which is necessary for long term success.

Removing plastics up-stream is significantly easier and cheaper before it hits the ocean.

A few recyclables are able to be sold in the local markets. Most of this is PET, glass or aluminum which averages around 3-5% of the ocean-bound waste. The main revenue stream is coming from “Plastic Fischer Credits.” Companies buy PFCs by paying Plastic Fischer per ton collected and processed to compensate for the plastic that they can't reduce within their supply chain.

Plastic Fischer barriers do require ongoing maintenance to remove and process the plastic, which is a condition currently present with all similar technologies.

The Plastic Fischer Credit (PFC) market is evolving at this time. The break-even point depends on the volumes of plastic that are being stopped. If enough companies pre-finance their expenses at a very polluted river, the site can become self-sustaining.

“Reversal” in this case could be defined as plastic being removed, only to end up in a river again, or a river barrier system breaking.

Plastics collected are verified and processed in the most safe manner possible so it will not end up back in the waterways. Plastic Fischer has partnered with Geocycle to create cement that is normally powered by coal-fired power plants, creating a solution that guarantees the plastic cannot physically re-enter waste streams.

With local knowledge of weather and by learning from complications of other boom systems during peak rain events, Plastic Fischer has designed emergency opening mechanisms that can release pressure created during heavy flow of rivers. They are able to open parts of the system itself, so that large volumes of water can pass and the equipment will not break and be washed away.

Plastic Fischer “key performance indicators” are 1) tons of plastic collected, 2) people employed full-time.

Plastic Fischer's goal is to protect marine habitats and biodiversity while motivating people to decrease the consumption of plastic products.

“We make sure that everyone we hire is joining the company with similar motivation. We hire similarly motivated people dedicated to honest impact with a primary focus for stopping plastic waste in rivers.”

Plastic pollution is a symptom of poor design in packaging and poor waste management. Plastics are not designed for a circular economy and it is estimated that 70-80% of ocean plastics from the land, usually end up being washed into the ocean from rivers. (WData).

Plastic pollution has become such a ubiquitous problem that it has been deemed as dangerous as climate change (BBC).

Plastic Fischer is not solving the root of the plastic pollution problem, but they are solving close to the root by focusing on rivers–which have been identified as a major contributor of ocean plastic.

So far during their operations, the only unintended negative consequences have been related to regular maintenance and how systems deal with flooding/heavy rainfall.

Plastic Fischer builds the systems to withstand heavy river flow and if there is a break, each boom is attached in a way that it can be recovered and repaired, reducing the possibility of losing parts of the boom into the environment. During the heaviest rains/flooding, the booms are removed from the river for safety.

In the worst case event that massive flooding destroys the system and it is lost, Dollar Donation Club still maintains that the net positive benefit of many months of preventing ocean-bound plastic from reaching the ocean is a net-positive impact.

One trade-off that Plastic Fischer has made has been to opt for manual collection of waste rather than automated collection with machinery.  It’s often difficult to access the waterways that Plastic Fischer works in; in these settings, manual collection (using appropriate tools and safety equipment) is more efficient than automated collection, and is necessary to stop the plastic in waterways to prevent it from reaching larger water bodies (where recovering it is almost impossible).

To ensure staff safety, Plastic Fischer trains their operational staff to minimize their touch points with waste and to use appropriate tools for every type of site. On-site safety supervisors make sure that all risks are minimized before starting to collect waste.

Despite rivers being identified as a major choke point for ocean plastic pollution, there have only been a handful of successful river barrier systems to date, due to a number of challenges inherent to the problem.

The flow of water in rivers--especially during peak rain events--can create challenging conditions for recovering plastics with barriers. Marine traffic, fish migrations and equipment wear and tear in water environments, create challenging conditions.

In a WWF paper on plastics and climate change they state,“In our oceans, which provide the largest natural carbon sink for greenhouse gases, plastic leaves a deadly legacy. It directly chokes and smothers a host of marine animals and habitats and can take hundreds of years to break down. As it does, sunlight and heat cause the plastic to release powerful greenhouse gases, leading to an alarming feedback loop. As our climate changes, the planet gets hotter, the plastic breaks down into more methane and ethylene, increasing the rate of climate change, and so perpetuating the cycle” (WWF).

Impact Stack

5.7

SDG01

Oceans and aquaculture provide employment for nearly 60 million people, provide a key source of protein for nearly 3 billion people and contribute 1.5 trillion dollars to the global economy, yearly. (WWF).

Communities globally are dependent on healthy oceans for their livelihoods. Plastic clean-ups are a crucial part of global economic security. Plastic Fischer's work directly prevents ocean-bound plastic, protecting the ocean and humanity's ability to generate economic stability from the ocean.

Furthermore, Plastic Fischer employs only local individuals to build, maintain and repair the river barriers, and hires local waste pickers to remove and process the plastic.

SDG02

Approximately 3 billion people in the world rely on seafood as a primary source of protein. Marine plastics are adversely affecting the marine life that humans depend on for sustenance. Without healthy fisheries and ecosystems, there is an increase in disease, poverty, starvation and displaced peoples. (WWF)

Plastic Fischer's prevention of high volumes of ocean-bound plastic directly mitigates the negative effects of plastic on global aquaculture.

SDG03

By collecting plastic from the rivers and ensuring safe processing, Plastic Fischer ensures that less plastic ends up in the food chain or is burned openly, causing toxic emissions.

SDG06

Plastic Fischer decreases the pollution in rivers before it ends up in the ocean. Specifically by focusing on rivers, Plastic Fischer is focusing on a major choke point in the global plastic pollution crisis. Plastics collected are recycled or used to create energy, ensuring that this is not entering landfills which can leach into groundwater creating a toxic environment.

SDG07

Plastic Fischer has partnered with Geocycle to create cement that is normally powered by coal-fired power plants, creating a solution that guarantees the plastic cannot physically re-enter waste streams. Plastic -- being a fossil fuel that has already been extracted from the environment -- can be used for energy production, which prevents additional resource extraction and leads to a net carbon offset.

SDG08

Plastic Fischer employs only local individuals to build, maintain and repair the river barriers, and hires local waste pickers to remove and process the plastic.

SDG09

Plastic Fischer's approach introduces basic waste management practices to regions that have little to no waste management. By working with local communities, their solutions help nurture local regions to take on long term approaches to waste management, solving the problem beyond their intervention.

SDG11

River barriers help prevent the proliferation of plastic waste into more dispersed environments (rivers, oceans), and help nurture local waste management infrastructure.

SDG12

Plastic Fischer's projects raise awareness about the effect of single-use plastics on global ecosystems, and encourage better waste management practices in the regions that they work in.

SDG13

Healthy and well-functioning rivers and oceans are critical to climate and atmospheric regulation. The removal of plastics assists the restoration of the ocean and its functions, which is an integral part of climate stability. See additional resources linked below:

Yale: plastics & climate change paper

Marine Plastics & Climate

Plastics and Climate Change

SDG14

Plastic Fischer deploys systems that are careful to allow safe passage of wildlife. By collecting dangerous waste, they stop ocean-bound plastic before it reaches the ocean. Furthermore, they prevent the creation of future microplastics which is a great cause of harm not only to marine and aquatic life, but to mammals, birds and humans.

(“Not just sea life”)

SDG15

Plastic Fischer's trashbooms reduce the degradation of natural habitats, halting and reversing biodiversity loss and land degradation, allowing natural systems to regenerate, creating cascading positive benefits for life on land (River plastic pollution).

Individual Questions

In 3 sentences or less, please describe your vision of the future when the challenges you seek to solve are solved:

“The beauty of the sea is slowly returning and marine life can be restored. We are living a sustainable lifestyle, consuming less and producing less plastic. Replace plastic with bio-materials and reusable, bio-benign packaging. This creates a world where toxic plastics are no longer manufactured, creating an environment for all life to thrive. And we are no longer needed.”

What makes you different from other organizations working in this area of social impact?

“We truly do what we say we will do. We are a learning company and question ourselves regularly. We are not shy to admit mistakes and change our approach. We do not want to be famous,and we are not looking to get a lot of followers on social media. We just want to clean up the rivers in the most effective way”

Plastic Fischer uses local low-tech systems locally that can be easily maintained, monitored and create local job opportunities to have the greatest impact on plastic diverted from oceans and landfills.

How did Plastic Fischer begin?

We travelled to Vietnam and saw the plastic pollution through the Mekong Delta. We realised that no one was taking care of rivers at this time and we decided to be the first company to focus on this. Fortunately, we now see a lot of companies going a similar way (Our Story).

See the team biographies in their words here.

What are the booms made of? Share a description and link to a photo or diagram. 

Plastic Fischer uses locally sourced galvanised steel frames and mesh + PVC pipes as floaters. All parts are low tech and are maintained and recycled when necessary.

Check out their design here!

What happens when the booms break or need replacing? Describe the end of boom-life plan.

“The trash booms are attached in a way that the system will open under heavy strain and no element will be released into the environment. We can also replace a single element quite easily by detaching it from the others and inserting a new one.

One system has been in the water since September 2019 and does not show any signs of failure. When a system is removed, all usable parts are recycled.”

What kind of relationship-building is needed to do your work?

Plastic Fischer must receive permission from local authorities to implement any technologies. They must build trust and relationships with the governing bodies as well as local community members and local recyclers and waste processors to optimize collective impact. Relationship building is paramount to the continuing success of local impact solutions.

How are the local populations affected by plastics? (health, economics, social, environmental, etc)

People often fish and swim in the polluted rivers. The plastic bioaccumulates in the food chain causing disease within the ecosystem and the humans that are in contact with it. Not only are there dire implications for the health of ecosystems, the seafood and fresh marine food species as well as human health, but the Ganges is regarded as a sacred river to the people of India. Protecting, preserving and regenerating these waters is profoundly culturally and socially significant.

Links to articles and papers on plastics as they affect the environment, economics, river and ocean health and human health can be found here.

Did DDC find any negative press about Plastic Fischer?

None.

Do animals ever get caught in the systems?

Every few days in Varanasi, Plastic Fischer reports that a cow, and other land-based animals are found in the river, caught by the trashboom. These are dead animals that have been swept into the river. When this happens, “our team calls employees that are being paid by the city to take care of situations like this. They bring the animal to a specific ground in the city. If the guy is late to show up, our staff pulls the cow aside behind the system.”

Plastic Fischer has not caught any dead marine animals in their systems to date!

What is the impact (positive and negative) on biodiversity in the river?

After a literature review and discussions with experts, we have not found reports of any negative impacts on biodiversity. All evidence we've found indicates that the benefits to river ecosystems would far outweigh any costs (source). However, we will keep monitoring in case any new information arises.

The barrier only goes 0.5 meters (1.6 feet) deep into the river, so fish can easily swim under. One unintentional positive benefit of plastic barriers is that they could help remove Water Hyacinth, a fast-growing invasive plant that causes massive problems in river ecosystems. Plastic Fischer is currently evaluating how to best remove and process Water Hyacinth waste.

Have there been any work related injuries connected to the trashbooms?

None reported so far.

How often are the trashbooms cleaned?

“Once a year we get the systems out and clean them. We have had no major algae growth problems on the systems.”

How deep do the trashbooms submerge?

Fabric trashboom - 0.25m deep

Regular trashboom - 0.45m deep

Walkable trashboom - 0.5m deep

How effectively does this solution leverage natural processes?

Trashbooms use the natural flow of water to consolidate plastic waste and channel it into one point.

Plastic Fischer's barriers are careful not to interfere with nature, and allow marine life to swim underneath.

By cleaning rivers from ocean bound plastics and microplastics, rivers and oceans can be revived.

The Context

About Ocean Plastics 

We have a plastic pandemic.

Plastic makes life super convenient for humans, and super inconvenient for everyone else in the ecosystems of planet earth.

At least 8 million tons of plastic enters the oceans annually. Marine animals ingest or are entangled by plastics, which causes severe injuries and deaths. Over 650,000 marine animals are killed annually by entanglement.

The issue of Ocean Plastics can be looked at in 5 large categories:

1. Manufacturing & consumption (the root issue) 

2. River pollution (feeding into oceans)

3. Coastal pollution

4. Ocean Macroplastics (big stuff)

5. Ocean Microplastics (small stuff) 

6. Recycling & Reuse

Manufacturing & consumption

Humanity has generated over 8.3 billion tons of plastic over the last 6 decades, and it’s estimated that 91% of that isn’t recycled.  At the same time, it takes over 400 years for those plastics to break down. 

To get to the root of the issue, manufacturers, companies and consumers must confront the reality that a paradigm shift is needed at the root.

River pollution (feeding into oceans)

Rivers transport between 0.47 million to 2.75 million metric tons of plastic into the ocean every year.  80% of ocean plastic pollution comes from land-based sources, and rivers are the main way that this plastic gets transported out to sea. Less than 2,000 rivers are responsible for 80% of all the plastic that rivers release into the ocean. 

Coastal Pollution

A less significant portion of ocean plastics drift from waste sites toward coastlines and ultimately end up in the ocean.

Ocean Macroplastics

The big stuff in the ocean is primarily abandoned fishing gear (up to 70% of all surface plastics are fishing gear). These “Ghost Nets” roam the ocean killing over 650,000 marine animals annually, destroying reefs and transmitting diseases between reefs (source).

Ocean Microplastics

Mid-ocean microplastics are easily the most challenging and difficult aspect of this challenge to tackle. These are plastic particles less than 5mm in length, and include microfibers from clothing, microbeads and plastic pellets (source). Macroplastics (like Ghost Nets) also eventually break down into microplastics over time.

The Dollar Donation Club Integrated Impact Score was designed to ensure that the world’s most powerful and holistic solutions are presented to our members. The goal is to identify acupuncture points of change – solutions that create maximum positive benefit using minimal resources, while triggering a large cascade of additional benefits.


More importantly, the Integrated Impact Score embodies our approach of smart-philanthropy.


It’s not enough for us to give with only our heart. We must also give intelligently – identifying solutions that address root causes, generate outsized measurable outcomes, integrate holistically into existing communities, consider long-term impacts, reduce the risk of unintended consequences and lead to self-reliant capabilities rather than co-dependencies.


It’s time for us to focus less on things like “overhead ratios” and more on the total, holistic positive result per dollar. Oh yeah, and it should be fun!


We believe that the best solutions...


  • Solve root-causes rather than symptoms.
  • Consider their impact 100 years into the future.
  • Produce massive impact efficiently.
  • Care for people and planet holistically.
  • Leverage nature’s and humanity’s best technologies.
  • Are radically transparent – financially and operationally.
  • Are resilient against threats of reversal.
  • Result in self-reliance, rather than dependence.
  • Clearly understand total costs to achieve outcomes.

This vetting methodology was designed with careful care to identify these solutions.



How we calculate the Integrated Impact Score:


Individual Dimension Score


The scores for each individual dimension (e.g. Transparency, Measurability) are calculated by adding up the total points (1-5) per section and dividing by the total possible points for that section.


Impact Stack


The amount of points awarded for the Impact Stack section is based on an assessment of how directly or indirectly and effectively or ineffectively the solution addresses a particular Sustainable Development Goal, using the SDG indicators as a guide. Impact Stack is treated like a bonus of points by adding up the total Impact Stack score and dividing by 10 (i.e. every 10 points gives a bonus of +1 to the final IIS score).


Overall Integrated Impact Score


The overall Integrated Impact Score is calculated by averaging the total scores received in each of the Individual Dimensions (e.g. Transparency, Measurability, etc.). We then add the bonus points awarded by the Impact Stack. Overall scores are rounded up to the nearest integer at 0.5 (e.g. if a score of 94.5 is calculated, the final score will be 95, if a score of 94.4 is calculated, the final score will be 94).
