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
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.
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
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
