FibreSorb™ is a biodegradable absorbent for the clean up of surface spills of hydrocarbon products and for the bioremediation of hydrocarbon-contaminated soils. FibreSorb™ is a patent-pending blend of cotton and other plant-based materials with additional nutrients, enzymes and microorganisms that enhance the biodegradation of both the FibreSorb™ and petroleum hydrocarbons absorbed therein. The “used” FibreSorb™ can either be left in place to biodegrade over time (see photos at right) or swept up and placed in a compost pile or container to promote the biodegradation of the FibreSorb™ product and the co-metabolic bioremediation of the petroleum hydrocarbons absorbed within the FibreSorb™, eliminating the need for the disposal of contaminated wastes.

The FibreSorb™ product can be used to promote the bioremediation of petroleum-contaminated soils by mixing the product into the contaminated soils. Large-scale soil bioremediation projects can be facilitated with the use of a pugmill to optimize the mixing of the FibreSorb™ product with the contaminated soils.

The bioremediation of FibreSorb™-treated soils can be enhanced by the periodic application of Geovation’s patented N-Blend™ nutrients. FibreSorb™ can also be manufactured and applied as briquettes, granules and pellets (see left). These value-added product forms not only simplify the handling and application of FibreSorb™ in the field, but they also sink in water, providing a cost-effective means for the in-situ bioremediation of hydrocarbons and PAH's in aqueous sediments beneath rivers, lakes, harbors, lagoons and similar, difficult-to-treat environments.
