Biogas & Biomass

1. Biogas / Biomass Group 7

2. I. Brief Description Ayessa Mae Macale

3. BIOGAS Biogas is a mixture of methane and carbon dioxide, produced by the breakdown of organic waste by bacteria without oxygen (anaerobic digestion).

4. BIOMASS Biomass is any organic matter — wood, crops, seaweed, animal wastes — that can be used as an energy source.

5. Biomass is all kinds of fuel from living sources. Biogas is methane .

10. III. Advantages Ednaliza Ringad

11. ADVANTAGES OF BIOGAS provides a non-polluting and renewable source of energy. efficient way of energy conversion (saves fuel wood). saves women and children from drudgery of collection and carrying of firewood, exposure to smoke in the kitchen, and time consumed for cooking and cleaning of utensils.

12. ADVANTAGES OF BIOGAS produces enriched organic manure, which can supplement or even replace chemical fertilizers. leads to improvement in the environment, and sanitation and hygiene. provides a source for decentralized power generation. leads to employment generation in the rural areas.

13. ADVANTAGES OF BIOGAS household wastes and bio-wastes can be disposed of usefully and in a healthy manner. the technology is cheaper and much simpler than those for other bio-fuels, and it is ideal for small scale application. dilute waste materials (2-10% solids) can be used as in feed materials. any biodegradable matter can be used as substrate.

14. ADVANTAGES OF BIOGAS anaerobic digestion inactivates pathogens and parasites, and is quite effective in reducing the incidence of water borne diseases. environmental benefits on a global scale: Biogas plants significantly lower the greenhouse effects on the earth’s atmosphere. The plants lower methane emissions by entrapping the harmful gas and using it as fuel.

15. ADVANTAGES OF BIOMASS renewable source of energy. comparatively lesser pollution generating energy. helps in cleanliness in villages and cities. provides manure for the agriculture and gardens. there is tremendous potential to generate biogas energy. cheaper and reliable.

16. ADVANTAGES OF BIOMASS it can be generated from everyday human and animal wastes, vegetable and agriculture left-over etc. recycling of waste reduces pollution and spread of diseases. heat energy that one gets from biogas is 3.5 times the heat from burning wood.

17. ADVANTAGES OF BIOMASS because of more heat produced the time required for cooking is lesser. pressure on the surrounding forest and scrubs can be reduced when biogas is used as cooking fuel. more cost effective means of acquiring energy as compared to oil supplies. growing biomass crops use up carbon dioxide and produces oxygen.

18. IV. Disadvantages Jenifer Vista

19. DISADVANTAGES OF BIOGAS loss of the organic waste for compost or fertilizer very limited in the quantity of electricity it can produce on the global scale little or no control on the rate of gas production encourage deflation of goods prices bring about high corruption level

20. DISADVANTAGES OF BIOGAS pollution would be on the increase both sound, air, & water pollution food shortage obnoxious smells degasification increase the risk of evaporation of ammonia it contains some gases as impurities

21. DISADVANTAGES OF BIOMASS agricultural wastes will not be available if the basic crop is no longer grown additional work is needed in areas land used for energy crops maybe in demand for other purposes some biomass conservation projects are from animal wastes & are relatively small & therefore are limited

22. DISADVANTAGES OF BIOMASS research is needed to reduce the costs of production of biomass based fuels major cause of pollution expensive to install technology to process & recycle wastes use up too much land

23. DISADVANTAGES OF BIOMASS maintaining a supply of the waste product in sufficient quantities to maintain energy production can be difficult burning produces greenhouse gases global warming

25. BIOGAS Abra Mountain Province Baguio City Pangasinan Pasay City Batangas City Quezon Province Cebu Palawan

26. BIOMASS Biomass Power Generation Mina, Iloilo San Leonardo, Nueva Ecija San Pedro, Laguna San Jose, Lipa City Natividad , Nueva Ecija San Vicente, Sumilao Bukidnon
