Of the 38% paper recycled in 2000, 24% was post consumer paper comprising 20% from the wholesalers and retailers, 2% domestic and 2% offices. At the time it was estimated that the potential for additional recycling from wholesalers and retailers is 19% (362 tpa), for domestic sources 17% (317 tpa) and 10% (194 tpa) from offices (DEAT, 2000).
GW 51 - Plastic
Plastic waste consists mainly of six materials, all polymers mainly from petrochemical origin, including (PACSA, 2011):
-
Polyethylene terephthalate (PET);
-
High density polyethylene (HDPE);
-
Polyvinyl chloride (PVC) – rigid (PVC-U) and flexible (PVC-P);
-
Low and linear density polyethylene (PE-LD and PE-LLD);
-
Polypropylene (PP) including expanded polystyrene (PS-E);
-
Polystyrene (PS).
Many plastics are packaging materials including bags, bottles and a variety of other containers, but it is also present in the form of pipes, furniture, textiles, etc in the waste stream. In the Western Cape, plastics contribute between 10% and 33% of the municipal waste stream (DEADP, 2011).
The recycling surveys done by PlasticsSA are considered to be the most comprehensive source of plastics waste data in South Africa. The 2010 survey (covering 2009 data) included personal interviews with 132 recyclers and telephonic interviews with another 49 recyclers. This survey concluded that 1 250 000 tonnes of virgin polymers were converted and 228 057 tonnes of plastics were recycled. This translates into a recycling rate of 18.3 % of all plastics converted. Materials that were not recycled in mentionable quantities include metalized and heavily printed PP films, post-consumer PVC-U and PS-E packaging, biodegradable and oxo-biodegradable films, multi-layer and multi-material packaging films, pesticide and agricultural drums, PET trays and cross linked cable insulation (Plastics Federation, 2010).
PMMA - polymethyl methacrylate
ABS - Acrylonitrile/butadiene/styrene
PA – polyamide (nylon)
