One process that is used to convert plastic into fuel is pyrolysis, the thermal decomposition of materials at high temperatures in an inert atmosphere. It involves change of chemical composition and is mainly used for treatment of organic materials. In large scale production, plastic waste is ground and melted and then pyrolyzed.
In the EU, 31% of plastic products go to landfill: but a process called "cold plasma pyrolysis" could turn them into clean fuels. In the EU, 31% of plastic products go to landfill: but a process ...
Advocates say the process, which uses high heat to break down plastic, would emit potentially toxic air pollution. This process uses heat to turn plastic into flammable fuel. Legislators want to ...
Materials may be depolymerized in this way during waste management, with the volatile components produced being burnt as a form of synthetic fuel in a waste-to-energy process. For other polymers, thermal depolymerization is an ordered process giving a single product, or limited range of products; these transformations are usually more valuable ...

The UTC Power fuel cell system uses natural gas which is converted in a "catalytic reformer" into hydrogen, carbon dioxide, carbon monoxide, and water. The hydrogen is used to run the four fuel cell stacks to produce electricity and the power plant then converts the exhaust heat into cooling and heating, turning potential waste into usable energy.
As global plastic production has ramped up in the last 20 years, so too has the concentration of these shredded, fossil fuel-derived polymers in human tissue samples.
From the start of plastic production through to 2015, the world produced around 6.3 billion tonnes of plastic waste, only 9% of which has been recycled and only ~1% has been recycled more than once. [7] Of the remaining waste, 12% was incinerated and 79% was either sent to landfills or lost to the environment as pollution. [7]
