Glue laminated beams     Beams made of lumber glued together. Replacements for solid wood timbers and steel beams.     Back to top       Green Certification     Landowners who actively manage their woods can apply for green certification. Two agencies perform reviews and issue certification for the Forest Stewardship Council (FSC): the non-profit Smartwood and the for-profit SCS (Scientific Certification Systems). Both agencies charge to ensure that land is properly and sustainably managed and that loggers employ best management practices (BMP) to cut wood on certified woodlots. To maintain its green certification status from landowner to consumer, lumber mills must also be certified in chain of custody arrangements, that is, they ensure that certified logs are stored and milled separately from non-certified logs. It was originally thought that certified logs would sell at a premium but that has not been the case in New England. The Quabbin Reservoir managed by the Metropolitan District Commission in Massachusetts was the first publicly owned land to be green certified. Back to top         Green weight     AThe term green weight specifically refers to the weight of freshly harvested wood that has the same moisture content (MC) as the standing tree. MC is defined as the weight of water in the wood expressed as a percentage of the weight of the oven-dry wood (wood from which all moisture has been removed). Also see "dry weight."     Back to top       Ground wood chips     Ground wood is usually produced from a hammer mill or tub grinder and appears shredded and fibrous with irregular sizes, depending on the screen or grate used. Ground wood is easily distinguished by its geometry from wood chips produced from mill chipper or a whole tree chipper (WTC). WTC and mill chips appear square and evenly cut rather than fibrous and irregular.     Back to top       Ground Wood Paper     Newsprint and other inexpensive paper made from pulp created when wood chips are ground mechanically rather than refined chemically.
