A method that may include a mixing step for mixing a wood powder and alkaline substances, a kneading step for feeding a mixture of the wood powder and the alkaline substances and a resin into kneading machine and kneading the same in a condition in which the resin is thermally melted, and a molding step for forming an interior part using a plant fiber-reinforced resin obtained in the kneading step.

A method for producing a lignocellulose plastic composite material, in particular a simpler and more cost-effective option for producing lignocellulose plastic composite materials. Thermoplastic particles and a mixture of water and lignocellulose-containing particles are supplied to a refiner, and the lignocellulose-containing particles are reduced to fibers in the refiner. The thermoplastic particles are supplied to the refiner in a melted or fused state, or are melted or fused in the refiner, so that the melted or fused thermoplastic particles and the lignocellulose-containing particles that are reduced to fibers form material composite particles in the refiner.

The biodegradable composite insulation material is a composite of wood from the date palm tree (Phoenix dactylifera) and polylactic acid. The composite may have up to 50 wt % date palm wood powder of maximum particle size of 212 m, the balance being polylactic acid (PLA). The composite may be prepared by melt blending the date palm wood powder with polylactic acid pellets in a twin screw extruder at 190 C., followed by compression molding the blend in a press or the like into the desired shape for building thermal insulation, and finally, annealing the molded product for three hours at 95 C. The composite material is biodegradable, thermally insulating, water-resistant and relatively strong.

An artificial flower, plant, or other botanical is produced from an aqueous agar-based solidifying mixture. The artificial botanical may be colored as desired by adding one or more colorants. The artificial botanical may also be scented by adding a perfume, odorant, or other scent. Because the artificial botanical is produced using the aqueous agar-based solidifying mixture, no animal-based gelatin products are used. The artificial botanical may thus also be edible and satisfies vegan diets. The artificial botanical may thus also be flavored by adding a flavoring, such as fruit, concentrate, or sweetener. The artificial botanical may be all-natural and edible by adding mica powder as the colorant and by adding glycerin as the flavoring.

Described herein are biodegradable composites and methods of forming the same. The composites generally comprise a base polymer, a plant-based filler material, and optionally a fragrant additive. The fragrant additives may be used for attracting animals to or repelling animals from an area. Methods of forming the biodegradable composites include an extrusion process using a melt formed from the base polymer and the plant-based filler material.
