Scientists at the Nimbkar Agriculture Research Institute at Phaltan in Maharashtra have developed a method to treat foul-smelling distillery wastes. What is distinctive is that they will be using solar energy and a chemical catalyst, which they have refused to name. Laboratary tests have shown that the method can detoxify 100 litres of diluted distillery waste water within five days. Results of the project are now with the Union ministry of non-conventional energy sources. They declined to disclose the name of the catalyst because they have applied for a patent.
