The present invention provides a moldable mixture containing large portion of agricultural fibers and small portion of a binding agent and a flow-promoting filler material. The moldable mixture is substantially free of formaldehyde, with low moisture content and high draw ratio. The present invention also provides methods of manufacturing molded products and related parts, based on the claimed moldable mixture. Molded products (830) and related parts such as runner (810) and plank (820) with light weight, high density and more complex profile are manufactured by the claimed methods including steps of providing required materials for a moldable mixture, mixing the provided materials to form a moldable mixture, shaking the moldable mixture in preparing for compression molding and compression molding the moldable mixture to form molded products and related parts.

The disclosure provides methods for producing plant-based compositions. The plant-based composition comprises a mixture comprising mucilage derived from Opuntia ficus-indica and polyurethane, wherein the mixture comprises at least about 10 wt % of mucilage. The plant-based composition further comprises a textile support coupled to the mixture, wherein at least a portion of the textile support is saturated by the mixture.

A process for preparing polypropylene particles by using recyclable coffee grounds plant fibers includes the following preparation steps: S1) preparing raw materials; S2) processing the raw materials; S3) mixing the raw materials to obtain a mixture; and S4) performing mixing and extrusion granulation on the mixture. The raw materials in S1 include 35-40 parts of coffee grounds powder, 60-80 parts of polypropylene resin, 2-5 parts of compatibilizer, 4-8 parts of toughening agent, 1-3 parts of diffusing agent, 1-3 parts of maleic anhydride, 0.7-1.6 parts of anti-UV agent, 3-6 parts of antioxidant, and 1-2 parts of white oil. The present disclosure adopts coffee grounds for mixing preparation, the discarded coffee grounds can be reused, the prepared polypropylene particles contain fiber components, and the performance of a material is improved.

The present invention provides a chitosan-based composition that can be converted into a self-supporting casted object having good tensile and compressive strength that can also biodegrade at the end of its lifecycle. The composition comprises entirely bio-based or bio-sourced reagents that can be converted to the final product via a polymerization process that does not require the addition of inorganic catalysts, synthetic materials, or otherwise hazardous chemicals to strengthen or modify its water resistance.
