Recycling of rubber wastes by devulcanization

Resources, Conservation and Recycling, 2018
Abstract Disposal of used tires and rubber wastes is one of the biggest challenges of the 21st century waste management. One of the environmentally friendly possibilities of recycling this type of material is to go through the breaking of their three-dimensional structure.

Grafting of Waste Rubber

Rubber Chemistry and Technology, 1990
Abstract By the redox method and by gamma irradiation, it was possible to graft ethyl acrylate on to granulate of waste rubber. The quantity of grafted monomer was larger when gamma irradiation was used. When combining ethyl acrylate with 5-methylene-2-norbornene in the redox system with the intention to introduce more double bonds in the ...

Studies of the thermal degradation of waste rubber

Waste Management, 2003
One kind of Chinese waste tire's sample was pyrolyzed under an inert atmosphere by using thermo-gravimetric apparatus (TGA) and differential thermal analysis (DTA). Different pyrolysis temperature ranges were determined according to the reaction transition temperature obtained by TGA and DTA.

Use of waste rubber as concrete additive

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2007
For resource reutilization, scrap tyres have long been investigated as an additive to concrete to form ‘Rubcrete’ for various applications and have shown promising results. However, the addition of rubber particles leads to the degradation of physical properties, particularly, the compressive strength of the concrete. In this study,

Pyrolytic Treatment of Rubber Waste: Pyrolysis Kinetics of StyreneButadiene Rubber

Journal of Chemical Technology & Biotechnology, 1996
The pyrolysis kinetics of commercial-grade styrene–butadiene rubber (SBR), which is one of the major constituents of tyre rubber as well as one of the principal products of the rubber industry in Taiwan, was investigated by a dynamic thermogravimetry (TG) reaction system in a nitrogen atmosphere over the temperature range of 400 to 950 K at the nominal

The status of recycling of waste rubber

Materials & Design, 2001
Abstract The significance of recycling of waste rubber in protecting the environment and conserving energy is discussed. Various kinds of recycling approaches to waste rubber are summed up, such as reclaiming energy as fuel, reuse of the products of thermal decomposition, cleaning of leaking oil, reuse after simple modification, regenerative rubber ...

Recycling of Rubber Waste

Polymer-Plastics Technology and Engineering, 2004
Abstract The most important use of rubber in tonnage amount is for tires and inner tubes. All tires of automobiles, trucks, buses, airplanes etc., are made from rubber due to its unique properties. Rubber is related to thermo-plastic-elastic materials and is turned to thermosetting on vulcanization during manufacturing of rubber products or tires. This

Alcoholysis of Silicone Rubber Waste: A Method for Efficiently Recycling Silicone Rubber Waste and Preparing Multifunctional Rubber Additive

Macromolecular Rapid Communications
ABSTRACTSilicone rubber waste was effectively degraded into liquid siloxane derivatives by using a green solvothermal alcoholysis method under mild conditions. The resulting products primarily comporised linear oligomers (P1, P2) and cyclic species (D3, D9), with composition significantly influenced by alcoholysis parameters.
