Plastic recycling

Grounds and Gardens manages waste and Recycling at Rhodes University.

Plastic is one of the most common forms of environmental pollution. It spoils public spaces and has a negative impact on health and wellness. Makana, the Eastern Cape, and South Africa, need to tackle this serious form of pollution!

The Plastic Waste Problem

  • Z‌ero Waste - the best option in the 'waste hierarchy'.

  • ‌Reduce unnecessary consumption, packaging and waste generation.

  • Re-use plastic waste creatively for arts and crafts. Visit Kisma Kreative.

  • Recycle - the last option in the 'waste hierarchy', delaying the entry of plastic waste into the system. 

If other options for preventing plastic waste are exhausted, it is possible to recycle most types of plastic.

Plastic Recycling Dos and Donts   

What's in? Bear in mind that exposure to some plastics may have health and safety implications.

  • Plastic numbers 1 (PET or PETE = polyethylene terephthalate; e.g. soft drink bottles), 2 (HDPE = high density polyethylene; e.g. shopping bags, shampoo bottles), 4 (LDPE = low density polyethylene; e.g. squeeze bottles, frozen food bags), 5 (PP = polypropylene; e.g. medicine bottles, yoghurt containers), 6 (PS = polystyrene; e.g. take-away food containers), 7 (miscellaneous other; e.g. 5 litre water bottles, nylon, DVD's, sunglasses, etc).

What's out? Bear in mind that exposure to some plastics may have health and safety implications.

  • Plastic number 3 (vinyl or PVC = polyvinyl chloride; e.g. piping, clear vinyl bags & packaging, insulator on electric wire, and some shampoo & detergent bottles, soft plastic toys, etc) - toxic dioxins (PCDDs or Polychlorinated dibenzodioxins) are released as a result of a combination of heat and chlorine.

  • Exposure of polycarbonate plastic bottles to boiling water results in much higher levels of a potentially harmful chemical, Bisphenol A (BPA).

  • Look for the Recycling Symbol & Number on the plastic. Find out more from the Daily Green's Recycling Symbols on Plastics and 3 Suspect Plastics to Avoid.
