Coffee farmers in Central American are using water used to
process raw coffee beans to fuel electric generators by extracting the methane
gas from it. The biogas generators are being fueled by these coffee byproducts
that used to pollute local rivers.
The fermentation of the coffee tree's berries leads to the
production of methane gas which is highly polluting and a leading contributor
to global warming.
This pilot project is being carried out at 19 farms in
Nicaragua, Guatemala and Honduras. It was launched in 2010 by Dutch sustainable
farming group UTZ Certified, seeking to use less water in coffee growing and
use it more creatively. Water use has fallen by more than 80 percent at the
coffee farms after implementation of the project.
Vera Espindola Rafael, Latin America coordinator for UTZ
Certified said, "We've had very good results. We've achieved all the goals
we set- producing biogas, reducing pollution and using less water."
UTZ is rolling out the
project in Colombia, Peru and Brazil. It is looking for funds to do the same in
Kenya and Vietnam.
