Talk about a neat idea. All you folks burning wood might want to keep a few boxes on hand for emergencies…
Bio Bricks™, a product that is clean burning, produces just 1% ash, is renewable and utilizes low value forest products. A Connecticut producer makes fifty tons of these a day and can’t keep up with demand. In fact, the biggest challenge facing this entrepreneur is a steady supply of dry wood chips of the appropriate size and consistency (ideally not more than 8% moisture content). The chips are fed into a hopper and compressed into bricks that are held together by the heated lignants in the wood. Bio Bricks have no additives and use chips and sawdust from clean wood (not pallets). You only need three of them to make a fire in your wood stove or fireplace, they are bug free, and can be stored indoors. 50 packages of these bricks are the equivalent of 1 1/2 cords of wood and are competitively priced.
