Green Gold Giant Company showcased its rubber recycling solutions during Rubbertech China

Shanghai, Chin – During Rubbertech China 2024 from 19th to 21st September 2024, Green Gold Giant Company displayed its advanced comprehensive solutions for the green and high-value recycling of waste tires.

At this exhibition, Green Gold Giant focuses on 3 major recycling sectors: equipment, materials and research and development, and introduced its Low Carbon Green and High-value Recycling Solution for Waste Tires to global customers.

Utilizing different types along with different application scenarios of waste rubber products, Green Gold Giant launched five comprehensive solutions for the green and high-value recycling of waste rubber and provides customized and efficient services for different customers.

The five solutions exhibited at Rubbertech China 2024 were:

• Devulcanization Equipment of Waste Tire by Multi-stage Screw Extruders
• Continuous and Efficient Pyrolysis Technology and rCB Modifcation Technology
• Complete Set of Equipment for Preparing Devulcanized Rubber from Waste EPDM
• Complete Set of Equipment for Preparing Devulcanized Rubber from Waste Butyl Rubber
• Waste Rubber Powder Customized Continuous Preparation of Waste Powder or Composite Particle Activated Rubber Powder Equipment

Solution 1: Devulcanization Equipment of Waste Tire & Rubber by Multi-stage Screw Extruders

They use waste tires 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 reprocessing and enabling the high-value reuse of waste tires. At present, this equipment has been applied in rubber companies of Europe and Asia. And its core patent has won the Excellence Award for Chinese Invention Patent.
This system uses the linkage technology of twin-screw continuous desulfurization under normal pressure and twin-screw continuous low-temperature refining extrusion technology to achieve the green preparation of recycled rubber. It is environmentally friendly, safety, labor saving, stable performance, clean and automatic.

More than 20 sets of the equipment have been sold globally. One Chinese tire company uses it to produce 150000 tons of recycled rubber annually, of which 100000 tons are used for their own production, customer self-use recycling rate is nearly 70%.

Solution 2: Continuous and Efficient Pyrolysis Technology and rCB Modifcation Technology

The pyrolysis production line of Green Gold Giant adopts low temperature anaerobic pyrolysis process for the resolution of waste tires. Through the thorough decomposition of the polymer in the waste tire, it returns to the small molecule or monomer state, produces fuel oil, rCB and returned steel wire. Under the premise of safe, environmentally friendly, continuous and stable operation, the waste tire can be recycled, harmless 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 tires 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: widely used in various types of waste rubber, low processing cost, efficient recycling, environmental-friendly and intelligent automation.

In the future, as a pioneer in recycling industry, Green Gold Giant will continue to take the mission of “making polymer materials more environmental-friendly and processing lower carbon,” providing high-quality solutions and services to global customers, and continuously promote the high-quality development of the industry.
