Biogas & Biomass

Biogas / Biomass

Group 7

I. Brief Description

Ayessa Mae Macale

BIOGAS

Biogas is a mixture of methane and

carbon dioxide, produced by the

breakdown of organic waste by

bacteria without oxygen (anaerobic

digestion).

BIOMASS

Biomass is any

organic matter —

wood, crops,

seaweed, animal

wastes — that can

be used as an

energy source.

Biomass is all kinds of

fuel from living sources.

Biogas is methane.

III. AdvantagesEdnaliza Ringad

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.

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.

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.

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.

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.

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.

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.

IV. Disadvantages

Jenifer Vista

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

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

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

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

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
