Forest product industry practices

Direct Combustion Systems. The direct combustion of biomass feedstocks is already widely practiced by several industries, especially the forest products industry. Many types of direct combustion equipment are commercially available for this purpose. New developments in direct combustion technology are expected to have a near term impact on energy supplies through the utilization... 

AssiDoman compares favorably with its Nordic competitors in environmental concerns, particularly with regard to forestry practices and the introduction of EMS. The generally high level of environmental compatihility in Nordic companies gives the Swedish forest product industry a lead over many international competitors in. 

More recently, interest has developed in the use of enzymes to catalyze the hydrolysis of cellulose to glucose (25—27). Domestic or forest product wastes can be used to produce the fermentation substrate. Whereas there has been much research on alcohol fermentation, whether from cereal grains, molasses, or wood hydrolysis, the commercial practice of this technology is primarily for the industrial alcohol and beverage alcohol industries. About 100 plants have been built for fuel ethanol from com, but only a few continue to operate (28).

The United States leads the world in the production and consumption of wood products. Therefore, silviculture is important to the future of industries that rely on healthy forests. Silviculture is being practiced throughout the globe, from single-species plantation silviculture in countries such as New Zealand, Brazil, and South Africa and in the southern United States to silviculture education in the historic forests of Europe, where the field of silviculture was born. In addition, forested wetlands and coasts in locations such as Australia and the United Kingdom are maintained through silviculture practices. Silviculturalists are necessary participants in meeting industrial objectives to eradicate insect pests and plant diseases that affect commercial forest lands. 

Dioxins are not manufactured as commercial products or ingredients. In chemical practice they occur as unintented byproducts of incomplete combustion and of certain chemical processes. Dioxins are formed whenever organic material and chlorine are present in an incineration process, in industry as well as in nature (e.g. forest fires, volcanoes). The formation is favored at temperatures of ca 300 C, at temperatures above 600 C, they begin to decompose, at temperatures above 850 C they are destroyed. The formation seems to be independent from the source of the chlorine, e.g. whether the chlorine is contained in a salt or in PVC.
