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.”
