M3RP: A sustainable waste recycling solution

Material Recycling and Resource Recovery Plant (M3RP) converts any carbon based waste into valuable fuel and product. Carbonaceous materials constitute feedstock such as tyres, plastics, rice husk, municipal bio-solids or sewage sludge, cloth, polymers, wind-turbine waste, MSW, plastic components in electronics among many others. The M3RP works on a process called advanced pyrolysis which is continuous, works in the absence of oxygen, is self sustaining and has a very good condensing / separation system.

M3RP Process

The feedstock enters the pyrolysis chamber from a feed preparation unit. A feed preparation unit is the most important step for any waste processing technology, since it increases the efficiency of the system and is cost beneficial. Some materials have higher moisture content and it is pivotal to reduce the moisture before the feedstock enters the pyrolysis unit, else the unit uses a lot of energy in removing the moisture before transforming the materials into fuel. The M3RP has an advantage over other pyrolysis units in that the feedstock can contain up to 40% moisture.

The absence of oxygen in this process inhibits the formation of dioxins and other environment depleting chemicals. It also prevents the burning of the feed and hence the pyro-gas obtained has high calorific value and the carbon formed is mostly of pre-graphitic state. The pyro-gas and liquid fuel obtained can thus be directly utilised in multiple applications, including a reciprocating engine, gas turbine and boiler. It is a self-sustaining system, as a fraction of the fuel formed is used to sustain the process.

Scogen specialises in wastewater treatment solutions and pollution control and has developed the patent pending waste management system, M3RP, in 2008. All M3RP units exported run on waste tyres, biomass and waste plastics. All waste is tested and proven on the full scale operating pilot plant at Scogen’s facility near Mysore. Scogen offers help to other companies wanting to install waste disposal plants.

Director Adishesh Barthur says, “The Indian market is reaching the right maturity to accept a technology such as ours. Scogen has already exported the plants to Europe and Far East and expects a strong growth this year.” Abijith Barthur, Director of International Business, adds, “We have companies from three different countries visiting us shortly. Ambient Energy LLC, USA is our marketing partner and has advised Scogen in the environmental issues pertaining to the unit that has made it marketable to the world.”.

Case Studies

  • MSW – Brazil (Testing)

A company in Brazil wanted to install a MSW to fuel processing unit and approached Scogen for a solution. Scogen received the ultimate and proximate analysis of the waste from Brazil. Scogen obtained similar waste in India and tested the waste during the company’s visit from Brazil.

Result: 100kg/hr of MSW was processed into 2kg of solid material, 57kg of gas, 29kg of oil and 10kg of water

  • Wind-Turbine waste

A wind-turbine company approached Scogen to solve the issue for its waste disposal. The waste was sent to the Scogen facility and tested in the presence of the clients.

Result: 80kg of wind-turbine was processed and 50kg of oil, 3kg of char and 27kg of gas.

  • Tyres

Shredded tyres were received from a client. The tyres were chipped to 50mm x 50mm. Result: 100kg of tyres were pyrolysed as the client witnessed the test. 45kg of oil, 35kg of carbon and 10kg of gas was obtained.
