PS plastic successes in South Africa

PS plastic CD case

Polystyrene (PS) is the sixth most widely recycled polymer in South Africa. This plastic is lightweight and durable – most commonly used in the food and restaurant industry. In fact, just over 5500 tonnes of PS was recycled in South Africa last year. It is one of the most widely-used polymers for food storage and takeaway containers, 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, PS packaging was the sixth-highest polymer in terms of volume processed. Most of the PS plastic waste comes in the form of fruit and vegetable punnets, meat punnets, takeaway cups and plastic cutlery. These materials are recycled into seedling trays, toys, hair combs and lightweight cement blocks for the building industry.

PS plastic recycling is a successful industry

PS waste is a fairly common material processed at South African recyclers because it is readily available due to its popularity in various industries. PS is popular in retail applications, such as clear food containers, as well as in the food and drinks sector. It also has many uses in the construction industry as expanded polystyrene is a perfect insulator and lightweight building material. 

The end-markets for clear containers and expanded packaging polymers, such as PS, are growing steadily year-on-year. The biggest end-market for recycled PS is plastic furniture, followed by domestic houseware. A small portion of recycled PS is sold to the construction sector, although this is a rapidly-growing end-market for this type of recyclate.

PS has a number of beneficial properties

PS is a unique combination of durability, economic viability and environmental performance. It has a low carbon footprint and uses very little energy to manufacture and recycle. One of the main advantages of expanded polystyrene is its resistance to heat, making it ideal for use as coffee cups, food containers and cutlery. PS is non-toxic and non-reactive, which makes it perfect for food contact applications and to prolong the shelf life of edible products. 

High-impact PS is transparent and durable, which is why it is commonly used for fruit punnets and CD cases. It shows off the product contained within, while also protecting it during transport and sale. This type of PS is also used to make retail coat hangers, laboratory ware, printers and keyboards, as well as computer and television housings.
