Solid Waste to Chemicals and Bioplastics

Detailed overview of innovation with sample startups and prominent university research


What it is

Waste-to-chemicals and bioplastics refers to the innovative process of transforming non-recyclable waste materials into valuable chemicals, fuels, and bioplastics. This approach to waste management not only diverts waste from landfills but also offers a sustainable alternative to traditional petrochemical production, reducing reliance on fossil fuels and promoting a circular economy.

Impact on climate action

Waste-to-Chemicals and Bioplastics innovation significantly advances climate action by reducing reliance on fossil fuels for chemical production. By converting solid waste into valuable resources like bioplastics, it mitigates greenhouse gas emissions, fosters a circular economy, and lessens environmental degradation, contributing to sustainable waste management and climate resilience.

Underlying
Technology

Several technologies are employed in waste-to-chemicals and bioplastics production, with a common theme of breaking down complex waste materials into simpler building blocks:

  • Gasification and Pyrolysis: These thermal processes convert waste into syngas or bio-oil, which can be further refined into various chemicals and fuels.
  • Chemical Recycling: This involves using chemical reactions to break down plastics and other polymers into their basic monomers, which can then be used to produce new plastics or other chemical products.
  • Biological Conversion: Utilizing microorganisms, such as bacteria and fungi, to ferment or digest organic waste, producing valuable chemicals like lactic acid or bioethanol, which can be used in a wide range of applications.

TRL : Varies depending on the specific technology and product, but generally ranges from 5-8.
