“MicroSludge and anaerobic digestion show great promise to recover green energy and fertilizer from WAS while reducing the consumption of petroleum-derived sludge dewatering polymers, potential aeration cost for the bio-treatment system and the amount of sludge requiring disposal”

MicroSludge reduces pulp and paper mill chemical costs, reduces sludge disposal costs, and converts a waste stream into renewable energy.

The treatment of wastewater at pulp and paper mills results in the production of huge quantities of waste activated sludge (WAS) which must be safely disposed. Conventional sludge disposal methods normally include, incineration, land-filling and land application.

WAS is not just a waste stream that has economic and environmental value as a source of green renewable energy and fertilizer that can lower greenhouse gas emissions and a pulp mill’s environmental footprint.

MicroSludge allows mills to economically extract renewable energy from pulp waste stream to improve pulp and paper mills’ environmental operating bottom line.

MicroSludge can be easily added to most pulp and paper mills to create a cost effective waste-to-energy solution.
