As an expert in the field of waste management and recycling, I have encountered numerous questions about the different types of recycling and their significance. One type that often raises curiosity is Type 7 recycling. This type of recycling is governed by a specific bill that allows CalRecycle, the California Department of Resources Recycling and Recovery, to determine which materials are considered recyclable and can carry the triangular symbol. It also gives plastic producers the opportunity to prove that their materials are recyclable and add them to the approved list. The main objective of Type 7 recycling is to increase the number of materials that can be recycled, as indicated by the triangular arrow symbol and the identification code of the resin.
This code ranges from 1 to 7, with Type 7 being the most diverse in terms of plastic materials.
