solid-waste management - Composting | Britannica
solid-waste management - solid-waste management - Composting: Another method of treating municipal solid waste is composting, a biological process in which the organic portion of refuse is allowed to decompose under carefully controlled conditions. Microbes metabolize the organic waste material and reduce its volume by as much as 50 percent.
USES FOR SAWDUST, SHAVINGS, AND WASTE CHIPS
same air-dry wood (12 pct. moisture content) would weigh 36 pounds per cubic foot, hence the sawdust would weigh 750 pounds when dried to 12 percent moisture content. Planing and machining of lumber and other manufacture from wood leads to further residues. A planer mill produces about 600 pounds of dry residue per thousand board feet.
Factors Determining Lumber Recovery in Sawmilling
Size, and Size of Dry-Dressed Lumber The size of rough green lumber includes allowances for the finished size of the dry-dressed lumber, planing allowance, shrinkage, and sawing variation (fig. 6). Mills often include more wood than needed for these allowances. This additional wood is known as oversizing.
