In a quiet field less than an hour’s drive from Haridwar, Uttarakhand, Dr Rajesh Jain is at his lab overseeing the collection, filtration, condensation and ultimate conversion of cow’s urine into Shuddhi—a new brand of floor cleaner. This cleaner, Dr Jain hopes, will be lapped up by all the country’s honest-to-god-I’m-sick-of-chemical-disinfectant hausfrau. “It’s 10 per cent cow’s urine, 90 per cent neem, eucalyptus and some other herbs from nature’s lap that I can’t name just yet,” he says. The unit, functioning from a cow shelter, can churn out 30,000 bottles of the stuff daily. Competition is heating up, apparently, as many others race to launch their own cow’s urine-based home cleaners.
