Permanent constant price increase for energy resources in Russia, strengthening of environmental requirements, as well as an increasing risk of power grid shutdowns and emergencies makes domestic experts and agricultural enterprises select modern processing and recycling technologies of cattle breeding and poultry farm waste.

The following problems can be solved by anaerobic digestion of biodegradable waste:

Implementation of environmental protecting measures to reduce toxic emissions into air, water and soil;

Increasing farm profits by using biogas for heat and power production, as well as offering to the market organic fertilizers with stable properties (absence of smell or repeated rotting), moreover 1 litre of which equals to 100 kg of manure used as fertilizers;

Improvement of reliability and safety in energy supply of cattle breeding and poultry farms by using its own renewable energy sources;

Improvement of soils fertility and fodder area crops by using fertilizers, as a source of biogenic elements and humus.

The technology of anaerobic methane digestion with regard to circulation of organics allows to create a system with closed cycle: crop raising - fodder and foodstuffs - waste - anaerobic digestion – crop raising. In this scheme agricultural sector is provided with fertilizers and fodders, and industrial sector (in case of methane recycling) with raw material and energy. This approach contributes to Kyoto Protocol and leads to the reduction of: pollutions, greenhouse gases emission and consumption of nonrenewable resources.

According to the statistics of German Biogas Association there are 2200 agricultural biogas plants currently in operation in Europe .

Distribution of total amount of agricultural sector organic waste among the federal districts of Russia (mln. Tons/%)

The largest share of organic agricultural waste (225 mln t. 36 %) is produced in the Southern Federal District. That’s why Krasnodarskiy Krai is the region of our interests. In the table below one can see data on waste productivity of Yeysk farms.

«GRETA ENERGY RU» and Yeysk administration are discussing feasibility of biogas plants construction using the waste of the above mentioned farms. For example we examined one of these farms – JSC “Rodina”.

The construction of bioenergy power plant and organic fertilizers production line using manure and agricultural

waste as raw material

The aim of the project is to construct biogas plant for JSC “Rodina” farm (Krasnodarkiy krai, Yeysk) operating on the base of recycling biomass and cattle breeding waste.

The project of constructing biogas plant goes along with «Russian Energy Strategy up to 2020» which defines the development of renewable energy as a priority direction.

The goals of the project and ways of achieving them.

Goals Ways of achieving

Improvement of reliability and safety of farms’ power supply

Construction on the territory of the farm, bioenergy plant, working on biogas, produced from the manure of the farm;Receiving additional heat from the heat exchangers of the fermented manure in methane tanks

Improvement of environmental protection

For atmosphere – prevention of biogas (methane) emissions and as well as reduction of natural gas used in heat production; For soil – prevention of contaminated manure and other biowaste emissions; For water – prevention of biogenic elements emissions into rain, soil, spring- flood and other water

Goals Ways of achieving

Improvement of economic effectiveness

Receiving additional profits due to:reduction of electric power purchase from utilities; reduction of natural gas purchase; reduction of mineral fertilizers purchase; Sales of bio fertilizers excess, obtained as a result of waste recycling; decrease of expenditures due to harmful emissions reduction.
