This document discusses biomass stoves and biochar technology. It aims to design an affordable, efficient, durable, and sustainable stove that addresses environmental stresses like climate change and human health issues from smoke. Biochar is produced by heating biomass in low-oxygen conditions, which converts agricultural waste into a soil enhancer. Biomass includes organic matter from various sources used as a renewable energy alternative to fossil fuels. While biomass energy is renewable and reduces dependence on fossils fuels, its combustion can cause pollution and potential deforestation if produced unsustainably.
Biomass stove & energy - Renewable Energy resource
- 3. VISION STATEMENT • To design an affordable, clean-burning, durable, safe and sustainable 'carbon negative' stove technology for the over-developed and under-developed worlds. WHY? • Increasing need for improving the affordability, efficiency, durability, safety and sustainability of cook stoves. • Interrelated environmental stresses connected to the design and usage requirements of stoves that affect human and environmental health and sustainability. • Stresses include climate change, biodiversity conservation, human respiratory health and e-waste - just to name a handful. • Purpose of study is to design a cutting edge stove that addresses these stresses
- 4. BIO CHAR • It is "the carbon-rich product obtained when biomass, such as wood, manure or leaves, is heated in a closed container with little or no available air“ • It is a 2,000 year-old practice that converts agricultural waste into a soil enhancer that can hold carbon, boost food security and discourage deforestation. • This process creates a fine-grained, highly porous charcoal that helps soils retain nutrients and water (International Biochar Initiative) • Main reason for biochar technology is to mitigate climate change, produce energy, improve soil and manage waste.
- 5. BIOMASS • Biomass is organic matter, which includes forest and mill residues, agricultural crops and wastes, wood and wood wastes, animal wastes, livestock operation residues, aquatic plants, and municipal and industrial wastes. • The biomass industry is receiving increasing attention from the public as scientists, policy makers, and growers search for clean, renewable energy alternatives. • Compared with other renewable resources, biomass is very flexible; it can be used as a fuel for direct combustion, gasified, used in combined heat and power technologies, or biochemical conversions.
- 6. Human Impacts: • 1.6 million people die from wood smoke related diseases each year. • Smoke from wood fire is one of the WHO’s top 10 threats to human health. • Depleted wood resource causes political instability. Environmental Impacts: • 14% of global warming attributable to black carbon. • Deforestation from wood collection. • Increased atmospheric CO2. Wood Consumption: • Half of all wood harvested in the world is used for fuel. • 75% of wood harvested in developing countries is burned for fuel.
- 10. BIOMASS PELLETIZATION • Biomass pelletization is the process of reducing the bulk volume of the material, by mechanical means for easy handling, transportation and storage of material. • In addition to the practical advantage of increased convenience, putting biomass in pellet form also decreases the moisture content, increases the density and maintains a high heating value.
- 16. PROS OF BIOMASS ENERGY • Renewable • Dependency on Fossil Fuels is Reduced • Carbon Neutral • Widely Available • It can be used to produce biofuels. • Helps Reduce Waste.
- 17. CONS OF BIOMASS ENERGY • The biggest contention against biomass as a clean energy is the pollution that is created from burning the wood and other natural materials. • Can Lead to Deforestation • The desire to produce energy on a large scale can lead to deforestation that would destroy the homes of large number of plants and animals.
