PVC plastic successes in South Africa

PVC plastic gumboots

Polyvinyl chloride (PVC) is the fifth most-widely recycled polymer in South Africa. This plastic is strong, durable and can come in three forms – rigid, flexible and liquid. PVC is considered to be one of the most versatile thermoplastics and it is recyclable in South Africa. It 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 – just under 21 000 tonnes of PVC plastic was recycled in 2018 alone. Of this volume, most of the PVC plastic came from gumboots, cables, hosepipes, plumbing pipes, conduit and gutters. These materials are mainly recycled into shoe soles, car mats and plastic speed humps.

PVC plastic recycling is a successful industry

PVC recyclate is currently in high demand due to its various applications and low energy requirements. This plastic is inherently flame-resistant and is impermeable to liquids. PVC is cost-effective to manufacture and, because of its versatility, it is an abundant plastic polymer. It is widely used in the construction, irrigation, medical, mining and motoring industry as a result of these properties.

PVC can also be recycled into various rigid, flexible and liquid products, including rubber shoes, flooring, trays, mats, insulation, raincoats and many more. The clothing and footwear industry purchases the majority portion of PVC recyclate, followed by the construction and agriculture sectors. This polymer has many uses as a recycled material in various industries in South Africa.

PVC has a number of beneficial properties

PVC is a popular plastic material because of its advantageous properties. During the manufacturing process, chlorine is obtained from ordinary salt and is chemically combined with ethylene, which is derived from coal in South Africa. PVC is always compounded with additives to give it a range of properties, such as rigidity, flexibility, fire resistance and liquidity. 

PVC has excellent resistance to wear and tear, making it ideal for products that need to withstand hard usage over many years. It is lightweight, cost-effective and requires little energy to manufacture. PVC is highly valuable in this regard as it supports economic development and the environment, unlike many plastic alternatives. These properties make PVC a popular plastic polymer. It is widely recycled in South Africa thanks to our strong and resilient recycling industry. For more information on South Africa’s vinyls industry, visit SAVinyls.co.za
