Coffee processing –
effluent treatment- cum-electricity generation:
The
integration of environmentally-benign disposal of
coffee-processing waste with power generation has obvious
benefits for the surrounding environment.
The biogas generated through anaerobic digestion of coffee
effluents can be used for fuelling energy services, while the
effluent-discharge is rendered ecologically benign and water can
be recycled for non-potable uses. An economic cost-benefit
analysis, based on the case of a particular estate, showed that
it was profitable to use the biogas so produced to replace a part of
the diesel required for electricity generation.
As coffee
production is important in the South-Indian economy and suitable
bio-reactors are available, this option was worth considering

With 100% biogas-fuelled engines now easily-available (and used
for powering a village sustainably, as described in the
Village energy
services section), effluent conversion to biogas
would be even more effective.
Environmental reform in the electricity sector: China and India:
A study of the environmental impacts of electricity generation
in China and India, along with their control and mitigation, was
carried out. As Asia's largest and arguably most dynamic
countries, the need for electricity in these countries has led
to rapidly increasing generation capacity that has overridden
environmental concerns. Our study has developed an
analytical framework consisting of identification of
environmental policies and regulations affecting electricity
generation, assessment of problems faced when implementing these
policies and regulations, and finally, recommendations for
surmounting the barriers encountered [click
