The present invention refers to a polymer composite that comprises sand preferably medium, at least a load, at least a resin selected from among dicyclopentadiene polyester resin (DCPD) and resin PET and at least a phase-compatibilizing additive and/or flexibilizing agent of the polymer structure. Further, the present invention refers to process of preparing said composite besides the use of said composite for preparing some articles including sleepers. This composite presents several advantages when compared to the materials used today for preparing sleepers as it is more versatile than steel, more available and as effective as wood, more durable than the concrete as it comprises an optimized composition that combines ideal physical-chemical properties to exercise the function for which it was intended.

Disclosed herein are systems and methods for processing waste egg shells into (i) a first product including calcified egg shell particles having diameters of 3 μ or less, and (ii) a second product including calcified egg shell particles having diameters in a range from about 3 μ to about 7 μ. The first product may be used as a CaCO.sub.3 substitute for paint compositions and plastics compositions. The second product may be used as a CaCO.sub.3 blasting media substitute for use with abrasive blasting equipment.

An environmentally friendly shoe component of a shoe includes scraps and an elastic material layer within which the scraps are distributed, the scraps include bottle scraps made by crushing plastic bottles, the elastic material layer is made of thermosetting polyurethane elastomer, and at least a part of the scraps is visible by a human's naked eye.

A foundry dust compound reinforcing filler for natural rubber contains 40-80 parts by weight of foundry dust, 10-40 parts by weight of silica and 10-40 parts by weight of Carbon black. A method for preparing a foundry dust compound reinforcing filler for natural rubber includes the steps of sieving, iron removal, pickling, precipitation, primary grinding, mixing, secondary grinding, granulation and the like. The foundry dust compound reinforcing filler used for reinforcing natural rubber is easy to disperse in natural rubber. The compound reinforcing filler has excellent reinforcing effect, which realizes the resource utilization of casting dust waste and reduces the consumption of silica and carbon black.

A shoe comprising an outsole, where the outsole is comprised of a rubber composition comprised of (A) diene-based elastomer comprising: (1) from about 20 to about 45 phr of high Tg SSBR pre-extended with vegetable oil, wherein said SSBR has a Tg in a range of from about −20° C. to about +10° C. and a bound styrene content in a range of from about 25 to about 50 percent and a vinyl 1,2-content in a range of from about 10 to about 80 percent based on butadiene content, (2) from 55 to about 80 phr of at least one additional diene-based elastomer comprising of at least one of polybutadiene, cis 1,4-polyisoprene rubber, and acrylonitrile-butadiene rubber, and (B) about 20 to about 70 phr of reinforcing filler comprised of a combination of carbon black and silica where the filler is comprised of from about 50 to about 100 weight percent silica.

Compositions (e.g., composites) containing processed solid waste, products made from the compositions, and systems and methods for making the compositions and products, are provided herein. For example, composites containing solid waste compositions and one or more added polymers, fillers, or other compounds are provided herein.

The present disclosure provides for articles formed of a filled polymeric resin material. More specifically, the present disclosure relates to polymeric resin materials that include a filler that includes of a mixture of cured rubber granules, foam granules, and/or textile fibers. The filler can be suspended in and/or encapsulated by the polymeric resin material. The polymeric resin material, the filler, or both can include waste or scrap material from manufacturing or from ground post-consumer waste.

Biochar can be used as an additive for bitumen. A bitumen composite includes bitumen and biochar. The biochar can include biochar from one or more of algae, food waste, animal waste, and cellulose-containing material (e.g., palm sheath). The biochar typically comprises 1 wt % to 20 wt % of the weight of the bitumen composite. The bitumen composite can be combined with aggregate to yield asphalt.

Embodiments of the present disclosure generally relate to reinforcement and filler materials in various compositions, and more specifically to coal-derived materials as reinforcement and filler materials. In an embodiment, a composition includes a coal-derived component and an elastomer component. The coal-derived component can be coal powder and/or coal char. The coal-derived component can be thermally-treated (e.g., pyrolyzed), solvent-extracted to produce an extract or residual carbon, and/or chemically modified prior to incorporation in the composition.

The present invention provides methods for preparing the nut waste pot composites from a nut waste component, one or more binders, and an oil.
