Overview
The term biogas refers to all the organic matter, produced by photosynthesis that exists on the earth’s surface. The source of all energy in biomass is the sun, with the biomass acting as a kind of energy store.[1]. The commonly used solid biomass in developing countries are firewood, dried dung cakes and charcoal.
Indoor Air Pollution
Burning biomass on fires or rudimentary cookstoves releases pollutants such as carbon dioxide , black soot and other green house gases (such as methane). These pollutants contribute to indoor air pollution, which is one of the major casue of death in SouthEast Asia. In additon, more than 200,000 people die prematurely, every year, due to indoor air pollution.
Black carbon, which results from incomplete combustion, is estimated to contribute the equivalent of 25 to 50 percent of CO2 warming globally. Methane emissions are the second largest cause of climate change after carbon dioxide. It is clear that inefficient household energy use has adverse consequences for the environment, air quality and human health.[2]
For more information about indoor air pollution , see the article on Indoor Air Pollution (IAP) and Indoor Air Pollution (IAP) Measurement
Solid Biomass and Climate Change
- Buring firewood results in deforestation which will further lead to natural calamities such as mudslide, landslide, flooding and soil weakening.
Carbon Debt
The extraction, transportation and combustion of biomass releases a significant amount of carbon into the atmosphere. This carbon is added to the atmosphere and it takes time before it is balanced by the ecosystem. According to a report by IPCC on renewable energy sources and climate change mitigation (2011), it can take decades, even centuries, before ecosystems; in particular forests can recapture the carbon that has been released during biomass combustion . This creates a "carbon debt" in the atmosphere.[3]
Each day , nearly 3 billion people cook using traditional fuel such as firewood, dried dung cakes or charcoal on open fires or rudimentary cookstoves. Mostly women and children are involved in coolectiong the biomass as well as in kitchen
For nearly 3 billion people each day, cooking is conducted on open fires or rudimentary cookstoves that are fueled by coal or solid biomass such as fire wood. Searching for and using solid biomass puts women and children’s safety at risk; depletes forests, which can weaken soil causing mudslides and destroying agricultural land; and jeopardizes human health and household and community air quality through toxic smoke emissions. Burning solid biomass is inefficient at converting energy to heat for cooking, and releases a toxic mix of health damaging pollutants that contribute to climate change at regional and global levels. In particular, some of these pollutants, such as black carbon and methane, have short life spans but significant consequences for the climate.
