Welcome to Sichuan

Sichuan has a long history, beautiful

scenery, rich products, pleasant climate,

famous with the reputation "Land of

Abundance".

Traditional Domestic Enengy

The rural population in Sichuan : 48 million

In the past:

- Large amount of energy consumption in rural areas

- Low energy efficiency

- Energy-use structure was not reasonable

Hometown of Biogas

As of October 2012,

Total number of domestic biogas plants reached 5.75 million

Sichuan started large scale biogas development the earliest in

China

Diverse scopes and ways of biogas construction

Large scale and higher construction quality

Comparison

Earthquake

On May 12, 2008, Sichuan province encountered an

disastrous earthquake,during which 524,100 biogas digesters

in the province were damaged,and the direct economic loss

is 1.6 billion yuan.

Biogas reconstruction

AFD and IFAD to provide the preferential emergency loans to Sichuan by a sum of USD

80.47 million,supporting 16 heavy disaster counties for reconstruction or new construction

of 155,300 biogas digesters. and all costs of the construction of the biogas plants covered

by IFAD and AFD .The other damaged biogas digesters are aided for restoration and

reconstruction by the domestic post-disaster reconstruction fund.

Project implementation

Project completed within three years in close cooperation

with partner organizations and under strict management for

quick construction and reliable quality.

Results

Housing

reconstruction

Energy recovery production recovery

Advanced technology

the body part of biogas digester is made of bricks or

concrete structure, and the gas holding dome part is made of

mold-pressed glassfiber materials.

Advantage

· Polymer materials ,mechanically molded, comparing with the ordinary biogas

digesters,the gas production increased by more than 26 %.

· The construction quality of glass fiber digesters is vastly improved.

· Avoids the multifarious process,save the time to build biogas digester,thus

greatly improving the project progress.

Construction way

The organization of professional construction teams , installation line

operation can avoid the process cross and delaying time limit of building

biogas digesters in the projects.

· Mechanization Excavation

· Professional Construction

· factory products

· Standard installation

Biogas service system

·The village biogas service networks

·county-level biogas service stations

Carbon trading

Planning Class Clean Development Mechanism (CDM) Project of

Sichuan Rural Middle-Low Income Family Domestic Biogas Digester

Construction.

Summary

The AFD and IFAD biogas projects, not only

solved the life energy-use for the earthquake

disaster area and helped the disaster area to

resume the production as soon as possible,

but also in biogas construction technology

and management field we broke convention,

developed ideas and innovated concepts for

future domestic biogas construction and

sustainable development to explore the new

mode, to realize the new span and put up

international cooperation new bridges,

attracting much attention of the parties both at

home and abroad.

Development Goals of Sichuan Province

· Development quantity large-scale

· Construction quality standardization

· Construction content diversity

· Biogas utilization efficiency

· Management and service socialization
