PP plastic packaging successes

Polypropylene (PP) is the fourth most-widely recycled polymer in South Africa. This plastic is durable, versatile and readily available around the world – in fact, just under 62 000 tonnes of PP were recycled last year alone in South Africa. PP is one of the most widely used polymers in the world and can be recycled into numerous products, making it a valuable polymer for the economy.

South Africa has some of the highest recycling rates in the world – last year we recycled 15% more plastic than Europe. Of this volume, PP packaging was the fourth-highest polymer in terms of volume of recyclate. Most of the PP plastic waste comes in the form of dairy containers, sweet wrappers, plastic furniture, houseware and buckets. These materials are recycled into refuse bins, shopping baskets, coathangers, flower pots and storage containers.

PP recycling is a successful industry

PP waste is a common material processed at South African recyclers because it is readily available and one of the most widely-used plastics. PP is popular in consumer applications, as well as industrial uses, making discarded PP waste an abundant material. It can come in the form of plastic products or a fibre twine.

The end-markets for containers and other semi-flexible packaging polymers, such as PP, are growing steadily year-on-year. The biggest end-market for recycled PP is domestic houseware, by far. This is followed by the furniture sector, then the electric industry. Some of the PP recyclate is sold to the rigid packaging and export markets.

PP plastic has a number of beneficial properties

PP fibre is easy to extrude and also has the right balance of toughness and flexibility to make a variety of woven products. The hollow nature of the fibre gives it excellent water (and sweat) absorption properties in clothing and other fabrics. Moulded PP products hold colour well, don’t absorb water and are ideal for robust applications, such as moulded car bumpers, luggage and storage boxes. 

PP has excellent chemical resistance. It is non-toxic and can be used in food-contact applications –  such as ice cream and yoghurt tubs. However, one of the main advantages of PP is that it is incredibly versatile and robust. This is why the polymer is such a popular choice and has so many applications in modern life. These properties make PP one of the most widely recycled plastics in South Africa.
