Biogas In Pakistan

Pakistan has low forest cover. About 4% of total area is covered by forest, in which only 5% area is protected.  90% of country’s wood production is used as fuel. About 7000 ha of land is reforested in Pakistan every year. To control reforestation adoption of biogas is a best technology in Pakistan. Biogas technology has proved to be very successful in Pakistan. These activities will not only be beneficial to the human health but will also have positive impact on the environment

Biogas is produced by mixing dung (Animal waste) and water in the absence of oxygen through fermentation process. Biogas can provide a clean, easily controlled source of renewable energy from organic waste materials for a small labour input, replacing firewood or fossil fuels (which are becoming more expensive as supply falls behind demand). During the conversion process pathogen levels are reduced and plant nutrients made more readily available, so better crops can be grown while existing resources are conserved.

Composition of Biogas

• Methane, CH4                              50-75%
• Carbon dioxide, CO2                   25-50%
• Nitrogen, N2                                 0-10 %
• Hydrogen, H2                               0-1 %
• Hydrogen sulphide, H2S              0-3 %
• Oxygen, O2                                  0-2 %

Composition depends upon the material feeded and process nature
