Our Technology

Levgum is spearheading global change in the rubber recycling industry through its patented breakthrough technology - the first high performance chemical modifier for the devulcanization of rubber waste. This has resulted in reducing the cost of recycled rubber to less than half that of virgin rubber.

Levgum's novel and innovative new process involves breaking down the sulfur links that are crossed between rubber polymer chains in vulcanized rubber. This enables waste rubber to be re-used, while retaining most of the properties and characteristics of the original rubber.

Levgum's highly efficient devulcanization process is carried out by adding Levgum’s modifier to vulcanized rubber brought into a stressed condition at a two-roll mill for about 20 passes. The superior quality recycled rubber which results from the Levgum process can either be used exclusively, or mixed with virgin rubber. This can amount to up to 30% of the total rubber used for each tire – a boon for the tire industry.

Levgum's mechanical-chemical process is carried out at room temperature, does not use harmful chemicals, does not produce or emit any hazardous waste or gases and is 100% environmentally safe.

As a result of Levgum's revolutionary technology, for the first time high-quality recycled rubber can replace natural rubber at a significant cost savings, thereby ensuring a better and more lucrative future for the entire rubber industry.
