NRRI Unveils Refined Solid, Renewable Biofuel
by Beth Bly (Business North) Executives from several partnership organizations were on hand Wednesday morning at UMD’s Natural Resources Research Institute Coleraine Lab as the Renewable Energy Lab was unveiled.
More than 10 years in the making, the lab currently has the ability to produce solid biofuel from wood waste on a “commercially relevant scale” of three to four tons per day. The briquette biofuel “replicates the energy output and durability of traditional coal” and can be used as an alternative to coal in electric power generation and other applications.
The briquettes currently are made through a heat treatment process known as torrefaction, which concentrates the energy content of the wood waste. Researchers describe torrefaction as a process similar to that used to roast coffee.
The darkened and pelletized renewable resource is easily densified, grinds easily, repels water and does not rot, making it easier to ship and store than unprocessed wood.
The lab will have further capabilities in the coming months and years. Further processing can be employed to create syn-gas or liquid fuels. READ MORE
