During Rubbertech China 2024 from 19th to 21st September 2024, Green Gold Giant Company showed its advanced comprehensive solution for the green and high-value recycling of waste tyres.
At the exhibition, Green Gold Giant focused on three major recycling sectors: equipment, materials and research and development, and introduced its low carbon, green, and high-value recycling solution for waste tyres to global customers.
Green Gold Giant launched five comprehensive solutions for the green and high-value recycling of waste rubber, offering customised and efficient services for different customer types.
The five solutions are:
- Devulcanisation equipment for waste tyres utilising multi-stage screw extruders
- Continuous and efficient pyrolysis technology and rCB modifcation technology
- Complete sets of equipment for preparing devulcanized rubber from waste EPDM
- Complete sets of equipment for preparing devulcanized rubber from waste butyl rubber
- Customised equipment for the continuous preparation of waste powder or composite particle activated rubber powder
Solution 1: Devulcanisation Equipment for Waste Tyres and Rubber by Multi-stage Screw Extruders
This solution uses waste tyres as raw materials. The equipment breaks the bonds of C-S-C, C-S-S-C, or C-Sx-C within the cross-linked network of waste rubber by physical or chemical methods. The waste rubber produced can be reprocessed, enabling the high-value reuse of waste tyres. At present, this equipment has been applied in rubber companies in Europe and Asia. the core patent has won the Excellence Award for Chinese Invention Patents.
This system uses the linkage technology of twin-screw continuous desulphurisation under normal pressure and twin-screw continuous low-temperature refining extrusion technology to achieve the green preparation of recycled rubber. It is environmentally friendly, safe, saves labour saving, offers stable performance, and is both clean and automatic.
More than 20 sets of the equipment have been sold globally, with one Chinese tyre company using it to produce 150,000 tons of recycled rubber annually, of which 100,000 tons are used for their own production, a recycling rate of nearly 70%.
Solution 2: Continuous and Efficient Pyrolysis Technology and rCB Modifcation Technology
The pyrolysis production line of Green Gold Giant adopts a low temperature anaerobic pyrolysis process for the resolution of waste tyres. Through the thorough decomposition of the polymer in the waste tyre, it returns to the small molecule or monomer state, producing fuel oil, rCB and returned steel wire. Under the premise of safe, environmentally friendly, continuous and stable operation, the waste tyre can be recycled, harmlessly and reduced with the equipment.
The system is equipped with strong flexibility and can match multiple devices in parallel according to customer needs to obtain stable products. Waste tyres can be thermally cracked to obtain fuel oil (45% -55%), rCB (30% -35%), steel wire (10% -15%), and non-condensable combustible gases for the system self-use (8% -10%).
This system has 5 major advantages, material adaptability, being suitable for various types of waste rubber, low processing costs, efficient recycling, is environmentally friendly and incorporates intelligent automation.
In the future, as a pioneer in the recycling industry, Green Gold Giant says it will continue to follow its mission of “making polymer materials more environmentally friendly and processing lower carbon”, providing high-quality solutions and services to global customers, and continuously promoting the high-quality development of the industry.
