    摘要: A cellulose mixture including a protein based adhesive binder and colorant. The mixture can be compression molded or extruded and upon curing in the presence of microwave or radio frequency energy or in thermally controlled appliance, produces board or shape formed stock. The produced stock exhibits colorations and a grain pattern comparable to natural stone. Unlike stone, the material exhibits a light weight, low density, structural rigidity and ready machinability. A preferred method includes admixing separate, colorized batches of feedstock, each feedstock includes shredded waste newsprint, soybean flour, water and a colorant; reducing the moisture content of each feedstock or a proportioned admixture of several feedstocks, such as by air drying or compressing or performing the admixture in the presence of heat; compacting the admixture to final shape; and curing the shaped material. Final forming and finishing apparatus complete the process.
