  • Patent number: 5728192
    Abstract: A method of processing fibrous waste materials, such as textile waste, in which the waste materials which are not particulate are formed into particles, and the particles are thoroughly mixed to form a waste mixture. The waste mixture has an increased temperature which allows the mixture to be used as a heat source as well as a plant growth medium. A particulate source of calcium may be added to the mixture if it is to be used as a plant growth medium. The plant growth medium may be mixed after formation with a dry wood waste mixture to enhance both its growth and heat properties.

  • Patent number: 5560767
    Abstract: A method is provided wherein wood-wastes in the form of stumps, limbs, branches, whole trees and the like are formed in a loose pile on a substantially flat site as a filled landfill or abandoned surface mine. The file is allowed to disintegrate until portions are of a crumbly texture at which stage large whole pieces in the pile are separated from the crumbly texture material which then becomes a useful wood-waste product and groundcover at the site at which the separation takes place. Deep-rooted plants are permitted to grow on the pile accelerate the disintegration.

  • Patent number: 5558694
    Abstract: A low-labor method of treating wood-containing or other cellulosic wastes to form a plant growth product. The wastes are formed into mounds containing soil or sand. Plants are allowed to grow on top of the mounds. When the wood becomes crumbly, the wastes are screened to form the product.
