Hampton Mill Co-Gen

Hampton's State Of The Art Mill
Is Thinking "Green"!

Hampton recycles all woody bio-mass waste and converts it to valuable "Green Tag" electricity.

Though not new to Hampton Lumber or the forest products industry, the energy in woody biomass is gaining recognition as an environmentally preferred alternative to the traditional sources of fossil fuel. The new Darrington sawmill cogeneration system reduces manufacturing costs by burning mill residual wood waste (biomass) instead of more costly fossil fuel to produce steam for drying lumber. In addition, the steam is converted to electricity by a turbine and generator.

The electricity produced is sold to the local utility, Snohomish Public Utility District, and because biomass is utilized as the fuel source, the electricity produced qualifies as renewable energy. Renewable energy has an additional value component for the environmental benefit of reducing greenhouse gas emissions. Each component generates additional revenue contributing to the mill’s bottom line.

Green Tag” is the common name for the property rights to the environmental benefits from generating electricity from renewable energy sources.  Green Tags represent the emissions from conventional electricity generation that are displaced when electricity is being generated from biomass, wind, solar, geothermal & some hydro sources.  Each Green Tag sold represents 1 Megawatt hour (MWh) of renewable energy produced.
