The technology exists to make a fully compostable, fully plant-based plastic product, but it is far more expensive than conventional plastics, and does not always work as well, especially if it is ...
In feedstock recycling, waste plastic is converted into its starting chemicals, which can then become fresh plastic. This involves higher energy and capital costs . Alternatively, plastic can be burned in place of fossil fuels in energy recovery facilities , or biochemically converted into other useful chemicals for industry. [ 118 ]
