A reclaiming agent is formed by grafting thiol groups onto styrene-butadiene rubber (SBR). The reclaiming agent has a weight average molecular weight of 1000 to 120000, which can be a random copolymer or a block copolymer. 100 parts by weight of styrene-butadiene rubber can be reacted with 0.1 to 50 parts by weight of the reclaiming agent to form a reclaimed rubber.

A method of producing a reclaimed rubber made of recycled shoe material waste includes the following steps. Step S1: collect a scrap rubber which is the shoe material waste. Step S2: grind the scrap rubber to form scrap rubber granules. Step S3: devulcanize the scrap rubber granules to form a reclaimed rubber. A reclaimed material for manufacturing shoes includes a reclaimed rubber formulation and a crosslinking agent, wherein the reclaimed rubber formulation is constituted by compounding a basic rubber formulation and the reclaimed rubber, wherein the reclaimed material for manufacturing shoes includes 65-94.8 wt % of the basic rubber formulation, 5-30 wt % of the reclaimed rubber, and 0.2 wt % to 5 wt % of crosslinking agent. Mechanical properties of the reclaimed material for manufacturing shoes meet required standards of shoe outsole material. A method of consuming rubber waste produced during the shoe manufacturing process is disclosed herein.

Sometimes, a problem is obvious, everyone sees it, but nothing happens until someone decides to do something useful about it. Methods are herein provided for recovering heavy hydrocarbons from plastic materials and/or geo-formation. In one solution set, PVC waste materials are emulsified by an amine solvent in an aqueous phase, thereby extracting heavier hydrocarbons from the primary structure of PVC into the amine aqueous phase; followed by de-emulsifying the extracted heavier hydrocarbons by separating and recovering the amine solvent, and then separating the de-emulsified heavier hydrocarbons from the aqueous phase by a hydrophobic membrane.

The present invention relates to a process for treating a polyamide-based composition which is intended to be recycled. More particularly, the present invention relates to a process for treating a composition, typically a powder based on untransformed polyamides during the manufacture of an object in 3D printing. The invention also relates to the use of the recycled composition.

Process for producing endcapped, liquid siloxanes having chain lengths of greater than 3 silicon atoms from end-of-life silicones, especially from silicone elastomers and/or silicone rubbers, by acid-catalysed depolymerization thereof in a solvent-free reaction system comprising at least one compound providing end groups M.sup.R, at least one compound providing D units, and at least one Brønsted acid.

A process for chemically recycling polyethylene terephthalate (PET) which utilizes a microwave absorber to optimize glycolytic depolymerization of PET via microwave irradiation. The method of chemically degrading PET to its reactive intermediate, bis(2-hydroxyethyl) terephthalate (BHET), is carried out by: (a) combining PET with ethylene glycol and a catalytic system comprising a catalyst and a microwave absorber to produce a heterogeneous reaction mixture; and then (b) heating by microwave irradiating the reaction mixture to a temperature sufficient to produce a reaction product comprising BHET. The BHET monomer then can be purified and re-polymerized to form new, virgin PET.
