Waste to Wealth


India Today - - SAFAI GIRI - —Aravind Gowda

When Mainak Chakraborty and two friends in Ben­galuru de­cided to start a new tech ven­ture in 2011, they did not have to think much. They were well aware of the garbage prob­lem in the city—ap­prox­i­mately 3,500 tonnes of waste gen­er­ated ev­ery day—and the poor dis­posal sys­tem.

“Un­like oth­ers in Ben­galuru, we did not want to tread the e­com­merce path. We wanted to make a mean­ing­ful im­pact on so­ci­ety and chose to ad­dress the garbage is­sue,” says Chakraborty, CEO of GPS Re­new­ables. The trio re­alised that tack­ling the garbage prob­lem at the source was one so­lu­tion—ho­tels, ed­u­ca­tional cam­puses and IT parks are the bulk gen­er­a­tors of or­ganic waste.

GPS Re­new­ables spent the first three years in R&D, per­fect­ing the tech­nol­ogy to con­vert or­ganic waste into en­ergy. The com­pany’s cus­tomised Biourja sys­tems are in­stalled at 70 lo­ca­tions in In­dia and Bangladesh to­day. The GPS Biourja sys­tem con­verts bio­waste into bioCNG, which can be used for cook­ing and ther­mal ap­pli­ca­tions. With a gas en­gine, it can even be used to gen­er­ate power. The resid­ual flu­ids can be used as fer­tiliser.

GPS has an im­pres­sive clien­tele list now—Ak­shaya Pa­tra Foun­da­tion, ITC Ho­tels, Taj Ho­tels, In­fosys, In­tel, Bosch, IIMBan­ga­lore, Ma­ni­pal Univer­sity, BITS Pi­lani and TVS, to name a few. The com­pany re­motely mon­i­tors its in­stal­la­tions round­the­clock from its Ben­galuru of­fice.

The Biourja suite con­sists of an in­put sys­tem with shred­ders, a gas stor­age sys­tem and a sludge de­wa­ter­ing sys­tem. GPS pro­vides gas pip­ing to the kitchen along with cus­tomised burn­ers.

In­vest­ment on a Biourja sys­tem is in the range of Rs 20­50 lakh, depend­ing on the clients’ needs. “Our clients can re­cover the in­vest­ment in two­and­a­half years. If our sys­tem is pro­cess­ing a tonne of waste per day, it is equiv­a­lent to sav­ing 25,000 kg of LPG ev­ery year,” claims Chakraborty.

GPS Re­new­ables broke even in its first year of op­er­a­tion and is tar­get­ing busi­ness worth Rs 20 crore this year.
