Potential of Biomass Project |
For
more than twenty years, Biomass and waste-to-energy has
been recognized as a clean, reliable, renewable source of
energy. Unfortunately in Pakistan this source of energy
has not been utilized for power generation in the past.
The growing urbanization and changes in the pattern of life
has given rise to generation of increasing quantities of
wastes and it’s now becoming another threat to our
environment. However, in recent years, waste-to-energy technologies
have been developed to produce clean energy through the
combustion of municipal solid waste in specially designed
power plants equipped with the most modern pollution control
equipment to clean emissions. Biomass and waste to energy
plants are used not only to generate sufficient power but
also used to cleanup the environment as well by conserving
non-renewable fossil fuel resources and reducing the environmental
impacts of trash disposal. Biomass and waste-to-energy facilities
can also contribute to the country’s economy by providing
jobs apart from generating electricity. |
| AEDB
is pursuing an extensive plan for the execution & implementation
of Biomass / Waste to power generation projects with the collaboration
of private investors in the country. AEDB is also fully supporting
& facilitating Sugar mills in the country for the production
of surplus electricity from bagasse and biogas. |
Every
city of Pakistan produces thousands of tons of solid municipal
waste as well as millions of gallons of wastewater. It can
be converted into energy and organic fertilizer. Biomass
like rice husk, cotton stalks, jute waste, bagasse and other
crop residues are also produced in thousands of tons in
Pakistan that can be used for power generation purposes. |
| Biogas |
Biogas,
one of the most significant types of biomass energy, makes
optimal utilization of the valuable natural resource of
dung. It provides (soot-free) clean gas for meeting cooking
and energy needs as well as enriched bio-fertilizer for
improvement of fertility/ productivity of agricultural lands.
Promotion of the biogas technology seems to be one of the
best options, which cannot only partially offset the fossil
fuel from wood consumption but also facilitates recycling
of agro-animal residues as a bio-fertilizer. Moreover, being
clean and renewable, it will also contribute towards environment
protection, sustenance of ecosystem and conservation of
biodiversity. |
Biogas
has proved to be a viable technology in the physical and
socio-economic conditions. Pakistan is rich in Biogas potential,
the technology provides nearly three times more useful energy
than that dung directly burnt, and also produces nutrient-rich
manure. Besides production of Biogas, the Biogas Plants
can result in improving economic and financial conditions
at micro as well as macro level and abating emission of
greenhouse gases that has been polluting the environment
due to its direct exposure. |
| Technological
Benefits: |
1.
Biomass and waste to energy plants
conserve fossil fuels by generating electricity. One ton
of MSW combusted reduces oil use by about 45 gallons; or
coal use by about 0.28 tons.
2. It has been estimated that one ton of MSW combusted rather
than land filled reduces greenhouse gas emissions by 1.2
tons of carbon dioxide.
3. Biomass and waste to energy plants do not have the aqueous
emissions that may be experienced in landfills, either now
or in the distant future.
4. Biomass and waste to energy plants save the space required
for land filling.

| Environmental
Benefits |
Biomass
and waste-to-energy projects have the benefits over conventional
energy resources projects that they do not emit any effluents,
pollutants and residues. These are considered to be most
environmental friendly technologies which are very much
supportive in reducing emissions and developing healthy
environment. All over the world, renewable energy projects
have been implemented to avoid dependency over the conventional
resources which have been a source of effluent emissions
and endangering the environment. The international organizations
and institutes including financing organization have been
encouraging such projects which utilize renewable energy
technologies for the generation of power. |
