摘要

A process for producing a product for use as an alternative cover material for landfills using recycled materials is provided. The process includes: receiving construction and demolition debris in a first area; receiving clean fill in a second area; positive sorting at least one of masonry products, concrete, bricks, cinder block, rocks, and asphalt from the construction and demolition debris; positive sorting a remaining portion of the construction and demolition debris to remove recyclable materials including at least one of cardboard, wood, fiber, ferrous metal and non-ferrous metal; negative sorting a remainder of the construction and demolition debris to remove materials other than wood, roofing material, plaster, plaster board and insulating board to form a first feed stock component; grinding the first feed stock component to a desired particle size of up to approximately six inches to form a first feed stock; mixing the at least one of the masonry products, concrete, bricks, cinder block, rocks and asphalt with the clean fill to form a second feed stock component; grinding the second feed stock component to a desired particle size of up to approximately six inches to form a second feed stock; and blending the first and second feed stocks in a proportion of approximately 2:1 to approximately 5:1 by weight to form an alternative cover material for landfills using recycled material.
