skos:Concept n9:Vysledek
dcterms:description
The concept of biodegradable plastics, i.e. biologically degradable materials, appears to be a possible solution for an ever growing production of plastic wastes as the biodegradable plastics shall have a substantially lower environmental impact and be able to at least partially substitute the production of plastics from oil derivatives. Currently, a promising direction seems to be the development of a polymer on the base of lactic acid (PLA). Packaging made from the material, mainly drinks bottles, could be used on a mass basis in future. Such generated waste will have to be recycled, which shall bring problems connected with separation of biodegradable material from common plastics. This paper deals with the issue of separation of PLA from PET using flotation. Mixing the above mentioned plastics in the recycling process leads to their devaluation. Due to the occurrence of PLA material the quality of the feedstock decreases during recycling PET bottles.
