Provided are a flexible material based on resource utilization of waste finished leathers and waste fabrics and a preparation method thereof. The flexible material is prepared form raw materials including the following components in parts by weight: 50 parts to 70 parts of a waste rubber powder, 10 parts to 20 parts of a waste polyester nano-powder, 10 parts to 20 parts of a waste leather powder, and 8 parts to 12 parts of an epoxidized natural rubber (ENR) curing agent.

A process comprising (a) providing a feedstock that includes carbonaceous materials; (b) gasifying the feedstock to produce a gaseous stream including carbon monoxide, hydrogen, and carbon dioxide; (c) converting at least a portion of the carbon monoxide, hydrogen, and carbon dioxide to butanediol; and (d) converting at least a portion of the butanediol to butadiene monomer

A method of functionalising an elastomeric material, such as a rubber particle, is provided. The method comprises the functionalisation of an elastomeric material through the use of an ionic liquid based composition, which comprises a water soluble polymer, a cationic silicate component, and a salt of a vulcanization accelerator, together with a zinc compound, sulphur, and an accelerator. Rubber particles, for example particles from recycled rubber products, functionalised according to the method disclosed can successfully be utilised in virgin rubber masterbatches at concentrations not previously possible.

A process comprising (a) providing a feedstock that includes carbonaceous materials; (b) gasifying the feedstock to produce a gaseous stream including carbon monoxide, hydrogen, and carbon dioxide; (c) converting at least a portion of the carbon monoxide, hydrogen, and carbon dioxide to ethanol; and (d) converting at least a portion of the ethanol to butadiene monomer.

A process comprising (a) providing a feedstock that includes carbonaceous materials; (b) gasifying the feedstock to produce a gaseous stream including carbon monoxide, hydrogen, and carbon dioxide; (c) converting at least a portion of the carbon monoxide, hydrogen, and carbon dioxide to methanol; (d) converting at least a portion of the methanol to butene; and (e) converting at least a portion of the butene to butadiene monomer.

Disclosed is a process for coating a product made of one or more of: rubber, recycled rubber, plastic, or recycled plastic. The product is coated with a base layer of an aromatic polyurethane mixture and then a top layer of a water-based aliphatic polyurethane. The top coating may include a colorant. The method provides an economical way to produce a recycled rubber product that has a uniform color.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.
