AC Biode develops chemical recycling a technology called Plastalyst. Plastalyst makes it possible to break down waste into core chemicals such as monomers, hydrogen (H2) and carbon monoxide (CO), syngas for SAF, and biodiesel. Organic waste is decomposed into alcohols and syngas, whereas plastic is decomposed into methanol, alkanes or monomers. It uses only water, waste, and a reusable catalyst as input. The reaction occurred at a temperature of only 200°C. Compared to other methods, our method has significant advantages such as low energy use, which results in lower operational cost. Next, we use water as a solvent, drying of waste is not needed, therefore it will cut the cost of preparing the material. Lastly, no solvent is needed and no CO2 is emitted in the reaction. Unlike organic methods, such as biodigestion that require a lot of time and emit a lot of CO2, Plastalyst is a fast chemical method that emits no CO2. We just started 2 pilots. 1 with Toyota/Toypet and 1 with Bosch to recycle their most difficult to recycled plastics, that are currently burned. This year we are starting our demo plant in Indonesia partnering with PLN. We already secured funding for this from the Temasek Foundation.

About me

AC Biode

  • chemically recycles plastics or organic waste, sludge or sewage that are currently not recycled at low temperatures. We are looking for technology collaboration with chemical companies.

  • captures CO2 through air filters and turns them into glass. We are looking for partners interested in small scale indoor DAC, AC unit, air purifier, dust collector and glass companies.

  • upcycles biomass ash that otherwise is wasted into glass or for soil treatment.

  • builds AC batteries for e-mobility and energy storage. We are looking for technology collaboration with electric vehicles.

  • sells catalytic pyrolysis converting plastics into oil. We are looking for technology collaboration with refineries & waste management companies. (Also for tires and medical waste).

  • sells instant houses that can be built in only 4h. We are looking for the next field trial + funding.

  • sells animal feed that reduces methane emission from cows by up to 98%. We are looking for partners to introduce this to new markets and pass local regulations.

  • develops fluorine-free water and oil repellent material. We are looking for companies that need R&D to replace PFAS & similar materials.

  • cleans microplastic from wastewater capturing CO2 in the process. We are looking for wastewater treatment collaboration for pilots.

  • creates micro droplets for drug delivery and cosmetics. We are looking for partners to test and scale our technology for different applications.

  • provides membranes to increase the efficiency of hydrogen to methanol conversion from 25% to 75%.

  • generates electricity for IoT from waste heat using flexible electronics.

  • separates precious and rare earth metals from waste using Galdieria algae.

  • recovers precious and rare earth metals from contaminated sites or mining waste using a combination of 20 different plants.

  • produces plastics from sulfur instead of carbon at room temperature.
