The brick oven pizzeria chain Bertucci's had a problem. Its wood-fueled ovens were producing a lot of ash and there were concerns about impacts on air quality. It's wood supply was hard to keep dry, and it was sometimes necessary to leave the next day's supply inside the oven after closing to dry out. These are big ovens, too, and require a great deal of fuel.
Enter 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.
The chimneys in Bertucci's restaurants only need to be cleaned twice a year instead of every other month since the switch to Bio Bricks™. As an alum of the pizza line at the Bertucci's in North Andover - ask me sometime about how to run 30 pizzas through a brick oven; that's one of my life skills - I can see how this product helps grow their business. Might be worth checking out yourself.
