Assisting the Development of Biogas Technology in Uzbekistan
Development of biogas technologies in Uzbekistan has good opportunities. The main sources of raw materials in the country, suitable for extracting biogas, are wastes of livestock breeding and poultry farming, municipal solid wastes, food wastes, industrial organic wastes, municipal sewage and residues of crops. There are about 9500 large and medium scale farms in Uzbekistan (with livestock consisting of 6.7 mln. heads of cattle, 12.4 mln.heads of sheep, 83.6 mln.heads of swine and 21.1 mln. of poultry). In spite of that, biogas technologies are not yet widely adopted in the country. Taking into account the importance of developing the biogas technologies, and other sources of renewable energy, the Government of Uzbekistan and UNDP launched a joint project “Assisting the Development of Biogas Technology in Uzbekistan”, at the beginning of 2006.
• Set up a pilot demonstration biogas plant at a cattle farm in Tashkent region.
• Conduct a feasibility study to asses the potential of raw materials for biogas production, assess the market for fertilizer selling, and assess capacities for replication of the biogas concept at other farms of the country.
• Implement a monitoring of technical, financial, economic and agro-technical aspects of the biogas plant operation during 2007.
• Develop recommendations on promoting of biogas utilization, including access to energy investment financing through Clean Development Mechanisms (CDM) or public and private partnerships.
Achievements & expected results
• First demonstration biogas plant has been placed into operation in “Milk-Agro” farm of Zangiota district, in Dec.2006. Volume of biodigester is 120 m3, gasholder’s capacity is 60 m3. The plant produces 300 m3 of biogas and 10 tons of liquid organic fertilizer daily. The biogas is used as fuel for forage preparation, for heating the facilities of the farm and greenhouse, for generation of electricity for lighting and mechanized milking. Obtained environmentally friendly and high-quality organic fertilizer is applied on 279 hectares of sown area, to substitute chemical fertilizers that were used before for growing wheat, corn, and alfalfa. The greater part of the fertilizer is sold to other farmers.
• The technical potential for biogas and organic fertilizer is assessed. The annual technical potential for biogas production from wastes of livestock breeding, municipal solid wastes and other organic wastes is estimated as 8.9 billion m3. Besides, mastering this potential can secure agricultural sector of the country with more than 14 mln. tons of environmentally friendly and high-effective organic fertilizer per year.
• Recommendations on ways of gaining access to renewable energy investment financing through CDM or public and private partnerships are studied. A publication on the use and development of biogas technologies is being prepared.
• In an effort to disseminate the project’ results and promote the knowledge, a “Training Centre for Biogas Technologies” was established.
