Abstract
Sawdust which is basically considered as a timber-industrial waste that pollutes the environment can become a valuable commodity which is considered in three ways: Manufacturing, Energy and Agricultural utilization. The sawdust is burnt in an updraft gasifier under a limited supply of air to obtain producer gas which is carbon II oxide and hydrogen as main components. The sawdust and other biomass materials are mixed in certain proportions, then bound together and palletized to a small blocks called briquettes. The material was also considered to be composted by mixing it with animal digestion or wood ashes and calcium carbonate to form fertilizers. The sawdust and wood shavings can be used for particle board as well as oil production.
Highlights
Sawdust is a tiny piece of wood that fall as powder from wood as it is cut by a saw [1]
Sawdust which is basically considered as a timber-industrial waste that pollutes the environment can become a valuable commodity which is considered in three ways: Manufacturing, Energy and Agricultural utilization
Sawdust is generally considered as a timber-industrial waste that pollutes the environment [3] but can become a valuable commodity either as a raw material in manufacturing industries for wood boards, light construction materials such as shelves, notice boards, wall and roof sheeting for mobile houses, as an insulator in the refrigerating system and cold conservation of in Energy industries as fuel burned directly or indirectly to produce wood gas, briquette, pellet, etc
Summary
Sawdust is a tiny piece of wood that fall as powder from wood as it is cut by a saw [1]. Sawdust is generally considered as a timber-industrial waste that pollutes the environment [3] but can become a valuable commodity either as a raw material in manufacturing industries for wood boards, light construction materials such as shelves, notice boards, wall and roof sheeting for mobile houses, as an insulator in the refrigerating system and cold conservation of in Energy industries as fuel burned directly or indirectly to produce wood gas, briquette, pellet, etc. In utilizing sawdust as a source of energy, its heating value can be compared with that of other fuels It has a very low thermal conductivity and used as insulating material so as to reduce heat losses through conductor. The exact conditions under which sawdust can be economically viable are hereby highlighted: 1) Energy industries, 2) Manufacturing industries, 3) Agricultural industries
