Biogas plant

Two ways technology returns value from waste

Written by: Alexa Stone

Dollars and energy are being heaped onto landfills in the form of  agricultural and food waste. Composting could reduce landfill trash by 30 percent, but only 4 percent of food waste is composted.

Innovative and effective use of today’s technologies can improve those numbers! Well-planned conversion of waste into renewable energy delivers significant bottom-line benefit.

These clean development projects are among the many that have achieved practical results:

Landfill gases boost thermoelectric power

Biogas in Brazil
A biogas capture system at a landfill in Brazil feeds into a thermoelectric plant. The organic residues from tree and garden prunings will provide an additional 1.5 MW of electrical energy.

The Caximba landfill had been deactivated in 2010, due to high Greenhouse Gas (GhG) emissions. With the addition of photovoltaic panels and biomass energy, GhG will be reduced while 5 MW of low-cost renewable energy will be produced.

 

Farm waste provides energy plus fertilizer

Hog farmIn Southern Brazil, a farm with more than 45,000 pigs generated about 3,500 m3 of manure and waste daily. Strategic investment turned that liability into an asset.

Distributed Energy Generation (DEG) from that farm now has a capacity of 1MW. The farm runs entirely on renewable energy. Nearly half of the energy it generates is sold to the local utility.

After DEG, the remaining solids are used as fertilizer. This has increased crop production by 70%.

Could your organization benefit from innovations in biogas and Solid Waste Management (SWM)?
