***Karachi has 400,000 milk-producing water buffaloes, the manure of which officials will collect and transport to biogas plants for conversion into fuel to power the buses. Over the next 30 years, this will allow the city to avoid pumping an estimated 2.6 million tonnes of carbon dioxide equivalent into the air. :flowers:
The conversion of Water Buffalo manure into fuel will also help the city save fresh water ? currently, Pakistan uses 50,000 gallons of fresh water to wash 3,200 tonnes of manure into the bay every day, according to the Reuters report.
Way to Go Karachi :biggthumb:***
