Instead of throwing wood chips away, shops can recycle them into wood briquettes, which can be used for energy in stoves, furnaces and in almost all solid-fuel burning equipment. The RUF briquetting machine takes wood chips produced by chippers that are up to 2 in. in size and presses them under high pressure into briquettes without using any bonding agents or other additives. The press automatically adjusts its settings to allow for changing incoming material. (440) 779-2747, RUF-Briquetter.com.
