PE-HD plastic packaging successes
High-density polyethylene (PE-HD) is the third most-widely recycled polymer in South Africa. This plastic is strong, scratch-resistant and non-toxic, making it ideal for use in the beverage and packaging industry. PE-HD is an abundant material and is quite easy to recycle in South Africa. It can be turned into numerous recycled products, making it a valuable polymer that can be reused again and again.
South Africa has some of the highest recycling rates in the world – 63 038 tonnes of PE-HD plastic was recycled in 2018 alone. Of this volume, most of the PE-HD plastic came in the form of milk bottles, plastic crates and plastic drums. These materials are mainly recycled into carrier bags for grocery stores and supermarket chains.
PE-HD plastic recycling is a successful industry
PE-HD recyclate is currently in high demand due to its durability. Although recycled PE-HD is not suitable for food contact applications (like the virgin polymer is), there is a great need for the recyclate in the agricultural industry. The main bulk of PE-HD recyclate is used to manufacture irrigation pipes, feeding troughs, fence poles and weather covers for the farming sector.
PE-HD can also be recycled into various flexible packaging products, including bin liners, recycled grocery bags and wood bags. The mining industry also accounts for a large portion of PE-HD recyclate, followed by the rigid packaging and construction sectors. This polymer has a variety of uses as a recycled material in various industries in South Africa.
PE-HD has a number of beneficial properties
PE-HD is an ideal packaging material because of its unique properties. It is produced from the polymerisation of ethylene at high temperatures, making it dense and robust. It is a highly crystalline polymer with strong bonds between molecules. These properties make PE-HD a dense plastic with high strength, high temperature resistance and excellent chemical resistance.
PE-HD has excellent corrosion and scratch resistance, making it ideal for products that need to withstand wear and tear or contain harsh chemicals. It is a lightweight and non-toxic plastic that lends itself to many applications in the packaging industry and a number of other sectors. These properties make PE-HD a popular plastic polymer. It is widely recycled in South Africa thanks to our strong and resilient recycling industry.
