More Information
Summary:Waste, such as municipal solid waste (MSF) or a portion of MSW, is separated into a wet fraction and rejects in a press. The press produces a wet fraction and rejects. The wet fraction may be treated, for example by anaerobic digestion or compost to thereby divert waste from landfill. The waste is pre-treated by spraying water at high pressure against the waste while moving or mixing the waste. The pre-treatment increases the amount of cellulosic material, such as paper or cardboard, that passes into the wet fraction.
