Abstract
A method of recycling construction and demolition debris produces a product useful in earth engineering applications, including landfills, soil stabilization and roadbeds. The method involves wet shredding construction and demolition debris into a moist shredded product and applying the product as daily cover for a landfill, or in a roadbed, or as a soil stabilizer or nutrient. A landfill design using the recycled product is also disclosed.
Claims16
A method of disposing of municipal solid waste and construction and demolition debris in a landfill comprising the steps of:
- dumping a first layer of shredded municipal solid waste on a landfill site;
- and
- applying a second daily cover layer over said first layer, said second layer comprising construction and demolition debris to which water is added during processing of the debris through a shredder into a moist shredded product.
A method of making a roadbed using construction and demolition debris comprising the steps of processing construction and demolition debris through a shredder, adding moisture to the debris during processing of the debris through the shredder, spreading a layer of the shredded construction and demolition debris over an earthen surface and mixing a portion of the shredded construction and demolition debris with a portion of the earthen surface to form a roadbed.
A method of soil stabilization comprising the steps of processing construction and demolition debris through a shredder, adding moisture to the debris during processing of the debris through the shredder, spreading a layer of the shredded construction and demolition debris over a soil surface to be stabilized and mixing said shredded construction and demolition debris with at least a portion of the soil of said surface.
A method of making a soil nutrient comprising the steps of processing construction and demolition debris through a shredder, adding moisture to the debris during processing of the debris through the shredder, mixing the shredded construction and demolition debris with a quantity of fly ash or sludge and applying the mixture to an area of soil.
