Wood agricultural production

The commercial uses of arsenic compounds in 1988, measured in terms of elemental arsenic, are wood (qv) preservatives, 69% agricultural products (herbicides (qv) and desiccants (qv)), 23% glass (qv), 4% nonferrous alloys and electronics, 2% and animal feed additives and pharmaceuticals (qv), 2% (see Feeds AND feed additives). Chromated copper arsenate (CCA) [11125-95-4] is the most widely used arsenic-based wood preservative. The Environmental Protection Agency has, however, restricted the use of arsenical wood preservatives to certified appHcators. 

Biomass potentials are mainly determined by agricultural productivity and the amount of land accessible for energy crop production. The total area under energy crops in the EU was around 1.6 million hectares in 2004 (estimate for 2005 2.5 million hectares), which represents nearly 3% of the total arable land. AEBIOM (2007) estimated a total biomass supply of 220 MtOE for the year 2020, while 23 MtOE are covered by wood-based bioenergy (direct from forests) and 88 MtOE by agriculture-based energy crops (by-products not considered). The Commission has estimated that about 15% of the EU s arable land (17.5 million hectares) would be used to reach the targets for 2020.

In this context, Fig. 5.16 indicates the dynamic evolution of the identified biomass primary potentials at the EU25 level, whilst Table 5.5 shows a detailed breakdown of corresponding fuel costs for the considered biomass options, including agricultural products or energy crops (e.g., rapeseed and sunflower, miscanthus), agricultural residues (straw), forestry products (e.g., wood chips), forestry residues and biowaste. 

The mill has also been used to grind industrial minerals and technical ceramics including limestone, lead zirconates, metal powders, fibrous materials, such as paper, wood chips and peat, and chemicals and agricultural products, such as grains and oilseeds. 

Renewable raw materials are made or derived from short-term renewable sources (one to a few years or a few tens of years) such as plants, trees, wood wastes and other agricultural products. Not all these materials are necessarily biodegradable. Natural rubber, for example, comes from the latex of a tree (Hevea brasiliensis) and is not biodegradable. Renewable materials are often considered as opposites to fossil sources such as petroleum that are not renewable on a human timescale. On the other hand, some synthesized plastics such as certain polyesters are biodegradable. 

The production of sugar from wood waste has claimed the attention of chemists for the last fifty years. It is of interest, both as a process of producing a supplement to agricultural products and also as a means of converting the vast amount of wood waste resulting from lumber manufacture into useful products.

Alumtnum phosphide, hke aluminum nitride, reacts with moisture but in this case the gaseous product is phosphine, PH3, a very toxic gas. For this reason, AlP is used as a fumigant to control insects in stored products such as raw agricultural products, animal feeds, processed foods (for example, flour and sugar), tobacco, wood, paper, leather, hair, and feathers. It is also used for control of rodents such as rats, mice, squirrels, and gophers in and around mills, food processing plants, warehouses and silos, and in rail cars, ships, and shipping containers. 

Waste materials cover a diversity of products such as wood waste, used tires, waste from agricultural products such as rice husks, and municipal solid waste. Some of these waste materials are very heterogeneous while others are more uniform. Different types of waste are commonly processed using incinerators or reactors that process waste material by heat. The processed materials are commonly classified in char, liquid, and gasses. The municipal solid waste (refuse derived fuel), which is probably the most heterogeneous, is initially processed by the removal of metals, is shredded, dried, and pelletized, and only after that is it processed in heated reactors.

Work is sponsored by the Department of Agriculture on the use of agricultural products in making plastics, largely by the Bureau of Agricultural and Industrial Chemistry. In addition, the Forest Products Laboratory has conducted extensive work on the uses of resins in wood and paper adhesives, impregnates, and laminates.
