I don't want to seem negative, but the issue here (unless it is a "hobby") is about the Laws (different even in countries belonging to EU) that regulate waste treatment. Only as an example (dated Strasbourg, 16.1.2018): https://eur-lex.europa.eu/legal-content/en/TXT/?uri=CELEX%3A52018DC0032 https://eur-lex.europa.eu/legal-content/en/TXT/?uri=CELEX%3A... The actual technical guide has been published soon after: https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=uriserv:OJ.C_.2018.124.01.0001.01.ENG&toc=OJ:C:2018:124:TOC https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=uriserv:... But nothing yet AFAIK to implement (and simplify where needed) the national Laws. Basically, at least here in Italy, besides the (not-trivial amount of) bureaucracy and paperwork needed to be authorized even for a tiny activity, you need an analysis (from an authorised lab) to classify each and every batch of plastic waste you process. And in some cases (some types of PVC come to mind) the material could be classified as "hazardous", and thus need to be disposed of by specialized firms (at a cost).
