Disclosed herein is a composite material composition for producing a biodegradable composite material. The biodegradable composite material is at least one of air resistant and water-resistant. Further, the composite material composition includes fiber present in an amount of from 30% to 50% by weight based on the total weight of the composite material composition. Further, the composite material composition includes starch present in an amount of from 20% to 40% by weight based on the total weight of the composite material composition. Further, the composite material composition includes filler particles present in an amount of from 20% to 40% by weight based on the total weight of the composite material composition and at least one binding agent present in an amount of from 1% to 5% by weight based on the total weight of the composite material composition. Further, the at least one binding agent is biodegradable.

Disclosed are microbial compositions having unique combinations of microbial species which are used in plant material recycling and retting. Also disclosed microbial inoculants which contains such a microbial composition, water, and an optional carbon source. The microbial compositions and microbial inoculants are particularly useful in recycling high lignin-content plant material. Methods of making and methods of using the microbial compositions and the microbial inoculants are also described.

A process for retting biomass includes contacting an enzyme solution with the biomass, degrading at least a portion of the pectin in the biomass using the enzyme to release monomers, proliferating bacteria using the monomers as a feedstock, and separating the cellulosic fibers after degrading at least the portion of the pectin to produce natural fibers. The enzyme solution comprises an enzyme, and the biomass comprises pectin and cellulosic fibers.
