Mexican firm in City for research in waste mgmt

At a time when the BBMP is looking towards the West for a solution to its own mammoth garbage problem, a Mexican city municipal corporation is pinning hopes on a City-based research institute to deal with its municipal solid waste (MSW).

A six-member delegation led by Carlos Francisco Authrey Maza, Chairman of Authrey Group of Mexico, has arrived here to study the feasibility of three patented technologies in solid waste management at the Scalene Energy Research Institute (SERI).

The three technologies – Dynamic Continuous Extra High Pressure Leachate Extraction Methanisation, Fine Particle Shortwave Thrombotic Agglomeration Reactor (FPSTAR) and Thermomegasonic Deagglomeration Reactor (TMDR) are claimed to be effective, safe and clean for the management of municipal solid waste.

 These technologies turn every bit of the municipal solid waste into useful products.Dr Rajah Vijay Kumar of Scalene Energy said: “Keeping in view the fact that segregation of waste at source has failed everywhere, our technology accepts unsegregated waste and converts it into Compressed Natural Gas (CNG), crude oil, fertiliser and pesticide. As a remnant, a minimal quantity of ash is also produced.”

How it works

A truckload of Municipal Solid Waste is fed into a container by what is known as the Integrated Urban Wasted Hydrocarbon Recovery System.

The waste is then washed in a high-pressure and high-temperature environment,- a process known as Dynamic Continuous Extra High Pressure Leachate Extraction Methanisation.

It strips out all organic matter and the inorganics, like the plastics, wood, metal, etc, are recovered and sterilised for safe and easy handling. Further, the inorganic substances will be conveyed to a trommel, a device that separates different materials as per their density.

The organic leachate will be subjected to FPSTAR, where water is recovered and used again in the process. The solids form a clot of rich organic hydrocarbons that are pumped to a Microbe Incubated Bio-Reactor, where the hydrocarbons are extracted as high-quality methane called Biothane.

The separated plastics will be fluidised and pumped into TMDR, where plastics will be exposed to very high-intensity ultrasound waves, adopted to generate crude oil.

Garbage economy

“All that is required is an investment of about Rs eight crore and by the end of the year, your investment will be back in your pocket. From 100 tonnes of waste, you will annually generate 8.76 lakh cubic metre CNG worth Rs four crore, 55,480 barrels of crude oil worth Rs four crore, 1,460 tonnes of fertiliser worth Rs 73 lakh and 40 lakh litres of pest repellent worth Rs 80 lakh,” Dr Kumar said. 

He added that his lab is self-sufficient. “We run our vehicles on garbage-generated CNG, cook our food, use the fertiliser to enrich soil and use the pest repellent to keep the plants healthy.”

The BBMP, which has been under severe criticism for the garbage crisis in the City, is aware of Scalene Energy but chose to look the other way and preferred calling Dubai and San Francisco for a solution.

Dr Kumar said: “If the West had the solution, why will the Mexicans, who have the United States of America as their neighbour, travel to India?”
