| An integrated system and method for removing excess nutrients from water, for removing the nutrients from the removal site, for enhancing soil, and for producing pulp and paper products includes bioremediating water to be treated with cultured algae or another suitable plant matter in an attached periphyton bed, harvesting the algae/plant matter to produce a wet algal biomass, and mixing the wet biomass with a shredded fibrous material to produce a pulp. The pulp can be molded into a biodegradable package that can be utilized as a delivery vehicle to a site having nutrient-enrichable soil, where the package can be used as a soil amendment after being used as a delivery vehicle. The pulp can also be made into a paper product that is biodegradable and has the characteristic of enhancing soil quality. | ||||||

| 225 | Arundo donax pulp, paper products, and particle board | US09741484 | 2000-12-15 | US20030019594A1 | 2003-01-30 | Ernett Altheimer; Michael P. Wolcott |
| Composite panels and pulp, and paper products of the pulp, are produced from Arundo donax. In the fabrication of the composite panels, Arundo donax is comminuted to a suitable size, combined with a binder, and consolidated into panels that meet standards for construction and/or furniture grade panels. The Arundo donax particulates may be combined with wood particulates to produce a mixed furnish that can be used in the preparation of composite panels. Comminuted Arundo donax is treated, in conventional pulping processes, to produce a high tensile strength pulp that can be used in the production of paper. The pulp has a lighter color than wood pulp, and thereby uses less bleaching chemicals to achieve a desired whiteness. The pulp can be combined with wood pulp to produce a variety of products. | ||||||

| 233 | Intergral pulp mill and method of constructing an integral mill | US710071 | 1991-06-04 | US5632859A | 1997-05-27 | Pertti Heitto; Vesa Junttila; Erkki Kiiskil a ; Tarmo Sulander |
| A mill for the processing and production of wood pulp is contained substantially entirely within a single, integral structure that defines a unitarily-covered space substantially bounding and enclosing the mill. The mill includes a main control room or station for overall monitoring and control of pulp processing operations in the mill, the main control station being disposed substantially centrally within the covered space, and a plurality of processing stations at which various pulp processing operations take place in a generally sequential manner or order. The plural processing stations are disposed within the covered space and radially outwardly from the main control station, with individual ones of the processing stations being arranged and located in the covered space relative to others of the processing stations so that as the pulp undergoes the sequential processing operations at the plural processing stations the pulp proceeds substantially circumferentially about the main control station between and among the individual processing stations. | ||||||

| 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. | ||||||
