Chemrec and NewPage team up to produce biofuels from black liquor gasification
The effort to utilize abundant industrial biomass waste streams for the production of biofuels continues. Swedish-based Chemrec AB and Ohio-based NewPage Corporation have formed a partnership to explore possible development of a plant that would produce renewable fuels from black liquor at the NewPage paper mill in Escanaba, Michigan. The agreement was announced by Michigan's governor Jennifer M. Granholm during a tour in Europe.
The proposed plant would employ Chemrec's black liquor gasification (BLG) technology, which converts waste from the paper pulping process into synthesis gas. The synthesis gas can be used to generate power and electricity, or processed into a variety of biofuels such as dimethyl ether (DME) and methanol (MeOH), or alternatively Fischer-Tropsch diesel (FTD), Synthetic Natural Gas (SNG), or hydrogen (H2) (schematic, click to enlarge).
According to Chemrec, the potential of this efficient fuel production process and the available feedstock is large. For Sweden alone, it could replace approximately 30 - 40 % of the country's consumption of petrol and diesel or 5-7 % of today’s electricity demand. The renewable fuels, produced in large-scale plants, would have prices comparable to fossil petrol and diesel. Well-to-wheel analyses show that the BLG production process is amongst the most energy efficient production routes to renewable fuels, and consequently results in high CO2 reduction levels (graph, click to enlarge):
For the Escanaba mill it is estimated that the process could yield up to 13 million gallons of liquid biofuel per year from the black liquor waste stream. The plant would be closely integrated with the paper mill to optimize energy efficiency and enhance the pulp production capacity of the mill. Chemrec's gasification plants can be fully integrated in existing pulp mill processes (schematic, click to enlarge):

Several European and U.S. studies have shown the BLG technology to provide a highly efficient and environmentally sound route for converting biomass to liquid biofuels. The technology does not require high-grade wood or woodchips.
Michigan's governor Jennifer M. Granholm made the announcement in Sweden following a reception with company and government leaders to celebrate the signing of a Memorandum of Understanding between the two companies. The governor and Michigan Economic Development Corporation (MEDC) President and CEO James C. Epolito are on the third day of an investment mission to Sweden and Germany.

We continuously search for ways to improve operations while at the same time improving our efficient use of renewable resources such as wood and wood waste. Liquid biofuel production using the BLG technology holds promise to improve efficiencies at our mills as well as becoming a source of valuable fuels and chemicals extracted from renewable sources. - Mark A. Suwyn, NewPage Corporation Chairman and CEOThe addition of Chemrec's BLG technology to NewPage's Escanaba mill is expected to create new on and off-site job opportunities. New jobs would be created at the NewPage facility for both biofuel production and for the enhanced pulping capacity. Additional jobs would include logging operations, transportation and maintenance jobs and construction jobs during the development of the plant.
