Abstract:
A process for waste reduction of household and other landfill waste material at a landfill waste management site comprising the steps of:grinding of the waste materials to produce ground-up waste material thereby reducing a volume of the waste material after the step of grinding;providing an above-ground holding cell having three side walls, an open side for vehicular access, an impermeable floor sloped downwardly towards the open side and a trench extending from the open side to a reservoir;driving a heavy machinery vehicle containing the ground-up waste material into the holding cell through the open side of the holding cell;depositing the ground-up waste material in the heavy machinery vehicle onto the impermeable floor so that ground soil is not contaminated by the ground-up waste material;composting the ground-up waste material in the holding cell thereby reducing organic material in said ground-up waste material to humus further comprising the steps of:adding water to the ground-up waste material to accelerate the composting;solubilizing heavy metals and other contaminants in the ground-up waste material into the added water, thereby forming a leachate; andchanneling the leachate away from the ground-up waste material and into the trench; andusing the heavy machinery vehicle to remove the humus from the holding cell via the open side of the holding cell.
