Abstract
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.
