The SM BG 10,000 Series Greasezilla from Downey Ridge Environmental comes preassembled, allowing for quicker on-site installation and startup. It processes concentrated raw trap waste into a marketable commodity – a clean product that has moisture content of less than 1 percent. Its hydronic heating system burns brown grease, producing the petroleum-free, green, renewable biofuel. The system can be accompanied by three 10,000-gallon double-walled process tanks built with a 3-inch interstice filled with a poured insulation, resulting in efficient heating and code compliance. It requires 120-volt power. 304/658-4778; www.greasezilla.com.
