Yes, we have a growing database of which materials are collected in schools. These materials include aluminium tin, plastic (PET 1, HDPE 2, PS 6, LDPE 4, Tetra Pak), and glass (not as common). There is also a significant amount of food waste generated by school, specifically at schools with feeding schemes. We help schools implement food waste systems using a combination of Bokashi bins and composting – we are in the process of finding a method for tracking this data.
We collect initial data from our waste audits which use a sample size of bins to identify and extrapolate the average types of waste a school generates; these inform the infrastructure we design and implement at a school. We collate all our waste audit data across schools to get an idea of what a typical school might generate. For each school we also collect and compile data from our partner recyclers from the invoices they send to schools which contains amount of waste for each specific waste type. This data is also collated into an overall dataset.
