New study suggests that plastic waste may be transformed into usable energy

A new study from the Earth Engineering Center (EEC|CCNY) at the Grove School of Engineering of the City College of New York suggests that plastic waste can effectively be converted into usable fuel and energy rather than being dumped in a landfill or polluting the ocean. Researchers found that the addition of non-recycled plastics (NRPs) to a chemical recycling process known as gasification results in the production of crude oil -based fuel. It also reduces pollution, both plastic and emissions, in contrast to traditional methods of disposing of plastic waste, such as incineration or dumping. Plastic is a product derived from crude oil and, as such, contains significant latent energy that can be harnessed using the right technology and technique. “This study demonstrates that because carbon- and hydrogen -rich plastics have high energy content, there is tremendous potential to use technologies like gasification to convert these materials into fuels, chemicals and other products,” study co-author Marco J. Castaldi told Phys.org . As concerns rise over plastic pollution, scientists are looking to reframe plastic as a resource rather than waste . “Plastics have an end-of-life use that will be turning waste into energy, which is something we all need and use,” study co-author Demetra Tsiamis told Phys.org.

This results in the creation of industrial gas mixtures called synthesis gas, or syngas. This syngas can either be converted into diesel and petrol or burned directly to generate electricity . This process is preferable to incineration of plastic waste because it allows for the storage of potentially usable energy that otherwise would be wasted through incineration. Gasification is also better for air quality, producing much lower levels of sulfur and nitrogen oxide emissions. + Earth Engineering Center Via Phys.org Images via Depositphotos (1, 2)
