A SYSTEM OF WASTE UTILIZATION WITH PROCESSES OF BIOLOGIC AND THERMIC DESTRUCTION

There are prognoses that wast mass will increase in the near future. Over half of waste mass makes various nature organic waste .At present waste is buried in landfill, partly recycled traditionaly by composting or utilized in biocells with collecting and employing of biogas. In this article considered conditional region (town and ambience willage )waste utilization with environment friendly modern biotechnology and traditional thermal process Liquid concentrated organic waste is recycled in closed biogas equipment, solid waste is burnt in gasification type furnace. Combining this equipment in complex is possible efficiently use energy obtained from waste. Examined influence of integrated processing system to environment, material and energy cyclization, efficiency employ of obtained energy and processing system comparing with waste burying in landfill

BIOFUEL FOR NATURE PROTECTION

Energy sector has been one o f the most important priorities since reestablishment o f the independence o f Latvia. The deficiency o f energy resources in Latvia has created a need to assess all the possibilities to utilize all the local enrgy resources, including the biological ones, to motivate the trends in the development of energetics in Latvia. Therefore data have been collected, calculations made and possibilities analysed to replace the imported energy resources. From the renewable energy in Latvia there are used the wind, solar, hydraulic and bioenergy. A biofuel programme has been worked out in Latvia. It is envisaged to develop the production of ethanol and rape oil for vehicle engines. For this purpose an arable area of 288 thousand ha is needed. A huge non-utilised reserve in Latvia is methane fermentation of organic agricultural and municipal residue and sewage from food industry. It is calculated that about 170 million m3 biogas can be obtained in Latvia. Implementation of the fuel programme will stimulate Latvia’s economy
