Plastic Fischer – Clean rivers, clean oceans

Plastic Fischer – Clean rivers, clean oceans

Fighting river plastic with a low-tech, open-source technology and an innovative funding scheme

Plastic Fischer is a young, agile startup from Germany which pioneers innovative schemes to collect river plastic in countries with a poor waste management infrastructure. The idea is to build a scheme, that allows local initiatives anywhere in the world to collect river plastic. The first schemes have been successfully tested in Bandung (Indonesia) and Bangalore (India); the next pilot is being prepared for Ho Chi Min City (Vietnam).

We support Plastic Fischer because we believe that their approach perfectly matches with our values, for three reasons:

  • About 80% of ocean plastic has been washed into the sea via one of the approximately 1600 polluted rivers. With its focus on river plastic, Plastic Fischer tackles the problem where it can be done most effectively. It is much more effective to prevent plastic from entering the oceans than to collect it out of the sea later on.
  • Even though set-up as a corporate, Plastic Fischer follows an open-source approach. The construction plans of their TrashBooms can be downloaded for free on the website. The rationale: No one in the world can solve the problem alone. The more local initiatives use the technology, the more plastic is prevented from entering the oceans. The TrashBooms are designed that they can be produced low-cost locally directly where they are needed.
  • In many countries there is an informal sector through which PET bottles, for example, are collected and sold already today. The used bottles have a market value and therefore locally recycling schemes have evolved by themselves. The question is: What about all the other plastic waste which cannot be recycled at cost? This is where Plastic Fischer comes into place. The company develops third-party verified “Plastic Credits” to be sold to corporates who like to off-set their negative plastic balance in order to reach a net zero target. Each plastic credit represents one ton of plastic that has been recovered from rivers and recycled or, where this is not possible, used to produce energy..

Plastic Fischer’s contribution to the 17 Global Goals

Life below water

Plastic Fischer prevents River Plastic from washing into the oceans and thus protects rivers and marine ecosystems

Industry, innovation and infrastructure

Developing an open-source approach to disseminating efficient River Plastic reduction technologies around the world

Sustainable consumption and production

Reuse of raw materials that until now have ended up as waste in the sea. Plastic Fischer contributes to a circular economy in places where this is particularly challenging.

Decent work and economic growth

Creation of new, secure jobs in low-income regions where the waste sector is often only informally organised

Partnerships for the goals

Engaging the corporate sector by offering “Plastic Credits” as well as the Plastic Fischer Club to help the transition to a net zero economy.

Clean water and sanitation

Cleaning up rivers as an important source of water for cities and communities. Removing waste is a first step on which further initiatives to improve water quality can build

Sustainable cities and communities

Contribute to the solution of the waste problem by recycling and, where appropriate, using plastic waste for energy
