4.127.59

Rural biogas management, extension and service systems have been established and improved throughout the whole country. Currently, there have been relatively complete management and extension, research and development and training and quality inspection systems across the whole country with 41,000 professional staffs, and 275,900 farmer technicians have been trained. This will serve as an ideal basis for our work.

The achievements

�

Through years of construction and development, remarkable achievements have been attained:

� the quantity of rural biogas construction keeps increasing� the investment structure keeps optimizing� the service systems are gradually improved� the functions of biogas are being further expanded� the biogas industry is developing quickly.

1. Rural biogas has maintained healthy and steady development

� 2009 35075.65

By the end of 2009, there has been 35 million household biogas tanks and 56.5 thousands biogas projects in China.

i. Historical Development of Household Biogas

The Energy Ecological Modes linked by household biogas

�

Four in One” Energy Ecological Mode

�

Pig-Biogas-Fruit ” Energy Ecological Mode

�

Five in One” Energy Ecological Mode

The “Four in One” Energy Ecological Mode in the North

�

The user needs to build a sunlight greenhouse in his rural courtyard, a underground biogas tank in one end of the greenhouse, and a pigsty as well as a toilet on the biogas tank. He may plant vegetables or fruits in the greenhouse.

Plastic green house

Carbon dioxide

oxygen

Organic fertilizerbiogas manures

The “ Pig-Biogas-Fruit ” Energy Ecological Mode in the South

�

The users need to make use of nearby conditions such as highland, water, and courtyard, build livestock and poultry houses, biogas tanks, and orchards, and integrate the construction of biogas tanks with that of livestock and poultry houses and toilets, which will make up of a courtyard economic system linking breeding, biogas, and planting.

The “Five in One” Energy Ecological Mode in the Northwest

�

Digester, toilet, solar energy warm sty, water cellar and garden irrigation facilities form an integral system.

ii. Present Status of Medium & Large Scaled Project

�

� Project construction is under steady progress

�

� Technical process keeps improving

�

� Remarkable benefits from comprehensive utilization

�

� Gradually matured operation mode

�

� Gradually improved standardization system2011/6/8 26

Promoting Mode for Medium & Large Scaled Biogas Projects

�

� Take Zhejiang Province as example. Four typical development modes are presented

� 1—

� Mode 1--- Energy ecological circulation mode

� 2—

� Mode 2 --- Energy ecological utilization mode

� 3—

� Mode 3 --- Comprehensive energy ecological mode

� 4—

� Mode 4 --- Energy ecological environment protection mode

2011/6/8 27

1—Mode 1 --- Energy Ecological Circulation Mode

�

� Feeding: the human and livestock wastes are fed to the biogas fermenting pool

�

� Features:

� Large yield of biogas

� Large yield of biogas manure

� A beneficial cycle in a small region

�

� Large dissolve area of the biogas manure land required

2011/6/8 28

Example of mode 1: Shaoxing Fujingda Cultivation Company

2—Mode 2 --- Energy Ecological Utilization

Mode�

� Feeding: separation method for animal and poultry feces (separate dry feces from wet ones) is adopted

�

� Features:

�

� Small yield of biogas

�

� Processing facilities for organic fertilizers required

�

� Biogas residues can be fully utilized

2011/6/8 29

Example of mode 2: Hangzhou Zhengxing Husbandry Co., Ltd

3—Mode 3 --- Comprehensive Energy Ecological Mode

�

� Feeding: the feces are fully or partially fed

�

� The feces are fully fed in summer

�

� Separation method is adopted in other seasons

�

� Features:

�

� Relatively high requirements on management

�

� Remarkable benefits from comprehensive utilization

2011/6/8 30

Example of Mode 3: Jinhua Jiale Dairy Company

4—Mode 4 --- Energy Ecological Environment Protection Mode�

� Feeding: separation method for animal and poultry feces

�

� Features:

�

� Fresh pig feces can be efficiently used for producing organic fertilizers

�

� The biogas slurry, after aerobic treatment, can be discharged or used for irritation.

�

� High operation cost

�

� Great difficulties in management

�

� Suitable for cultivation enterprises with no fertilizing conditions

CDMiii. Substantial progress has been made in the development of

rural biogas CDM project

� CDM

Household biogas CDM methodology has been developed for the first time

� CDM /

CDM

The household biogas CDM methodology developed independently by Chinese experts: “Methane recovery methodology in agricultural activities of peasant households/small scale farms” has been recognized by CDM Executive Board

2011/6/8

CDMChina has successfully registered two biogas CDM projects

� 2009 2 19 CDM8 3.3 5.84 CO2

On February 19 2009, the household biogas CDM project in Enshi, Hubei was successfully registered. Covering 8 counties and 33000 biogas peasant households, the project will cut CO2emission by 58400 tons each year.

� 174 60%18% 22%Each household may get RMB 174 Yuan of income from emission reduction on an average basis. Among them: 60% will be given to the peasant households, 18% will be used to provide technical service, and 22% will be used to conduct supervision and management.
