CHEMICAL RECYCLING OF POLYMERS
Excessive growth in recent years on the market of plastics materials
has increased the amount of wastes. Therefore, there were made a lot of
researches on plastics materials in order to establish an economically viable
method of recycling, with low environmental impact. A method that meets these
conditions and witch does not require any washing and separation of polymers
and/or waste materials based on these polymers, is the chemical recycling by
“pyrolysis”. By pyrolysis process, wastes are converted into liquid fractions
close to commercial fuels, in certain reaction conditions. The results obtained
are influenced by the temperature and catalysts that were used. The paper is a
review of literature data related to chemical recycling of polymers.
