(The Gist of Science Reporter) Quantum leap?
Of course, in India, wastewater collection and treatment needs to be improved
first. Nutrient recovery for fertiliser use subsequent to use of the 'organics
in the sludge for biogas production and energy generation must follow. As these
two steps will contribute to combating the energy scarcity and supporting
farmers on the one hand, and truncating the carbon footprint related to
electricity and heat production, and the synthesis of chemical fertilisers on
the other. Eutrophication of water bodies will be controlled and perhaps a good
deal of the treated wastewater can also be recycled, solving water scarcity
problems as well in many parts of the country.
While those are essential first steps which are to be focussed on-taking
leaves out of the books of countries in Europe, like Sweden for instance
-researchers in India will surely be interested in futuristic possibilities like
the one discussed in this article, and micro-scale projects may be conceived,
funds permitting, to start a trend, which may entrench itself in the
not-too-distant future. Circular-economy thinking must become second nature
sooner than later.
