WHY WASTE TO ENERGY

• The amount of solid waste generated each year has been

increasing much faster than population growth. Growing demand

of energy is also increases.

• Today, we face numerous environmental & economic challenges:

• • Population growth and associate waste disposal needs

• • Global Warming

• • Dependence on fossil fuels

• There is a common solution for all of these challenges.

• Energy-from-Waste (EfW) provides:

• • Safe, economic waste disposal

• • Greenhouse gas reduction

• • Renewable energy

WASTE TO ENERGY

• Waste-to-energy uses trash as a fuel for

generating power, just as other power plants

use coal, oil, or natural gas. The burning fuel

heats water into steam that drives a turbine to

create electricity. The process can reduce a

community’s landfill volume by up to 90

percent, and prevent one ton of carbon dioxide

release for every ton of waste burned.

BIOCHEMICAL REACTOR

• “An anaerobic digester is an air tight, oxygen‐free container

that is fed an organic material, such as animal manure or food

scraps.

• A biological process occurs to this mixture to produce

methane gas, commonly known as biogas, along with an

odor‐reduced effluent. Microbes break down manure into

biogas and a nutrient‐rich effluent.”
