Northern Tilth completed two years of agricultural and topsoil blending field trials for FMC BioPolymer, a carrageenan manufacturing plant that generates 23,000 tons per year of Algefiber, a spent-seaweed by-product. Prior to Northern Tilth’s work, all of the Algefiber was disposed in a local landfill. Based on the field trials and extensive materials characterization, Northern Tilth permitted and initiated a recycling program that currently handles 100% of the material.
