Anotace:

Solid biofuels made from agriculture waste become a prospective environmentally friendly source of energy that has many advantages comparing to fossil fuels. Tajikistan has many well-developed regions of agriculture, which not only play a crucial economic role at the same time also, generate wastes (biomass) collected each year in large quantities. This dissertation has focused using agricultural waste (cotton bush and apricot tree branches) as renewable source of energy in Tajikistan. According the data from laboratory research and settled hypothesis following conclusions were made. The energy potential of abundant agricultural waste, in the processing of cotton bushes and apricot tree branches as briquettes and pellets, seems to be one of the most effective energy and environmental solutions for Tajikistan, cotton bush and apricot trees as biomass in Tajikistan has big prospective of using them as renewable source of energy.

Abstract:

An increasing awareness of the negative environmental cost associated with the combustion of fossil fuels and concerns over the geopolitical instability of the main oil-producing regions is driving the development of renewable energy sources and biofuels. Use of solid biofuels made of different types of biomass became perspective alternative to conventional fuels in many countries. Such positive indicators as low cost of the final product that meets the quality of standards, not capital intensive production, possibility of producing briquettes/pellets from almost any agricultural waste or combination of raw materials are undoubted advantages of biomass based fuels.The main challenges for Tajikistan’s energy sector, which is depended on energy imports, are: to increase energy supply through better exploitation of hydropower and other renewable energy sources such as wind, solar and biofuels.Tajikistan, which is highly agrarian country, cotton and apricot are one of the most producing agriculture products in Tajikistan. Plenty of unused cotton stalks and apricot tree branches-residual biomass could be effectively utilized for winter heating in rural areas.
