Mars Group of companies having professional expertise in Waste to Energy and Solid waste management activities was established by Mr. Badri Narain Tiwari who has an experience of eleven years in the field of solid waste management and waste to Energy.
The organization which is family owned but professionally managed consists of devoted people to take care of the environment. Mars Group is one of the pioneers in providing a total solid waste management and waste to Energy facilities to Municipal Councils and Corporations. Mars Group has the potential to take over substantial work of the health department of Municipal Councils.
During its stage of inception, Mars Group studied the characteristics of waste generated in India. With special focus toward the developing urban area of India they have studied various kind of waste generation from different socio-economical classes of the society in urban India. They carried out physical and chemical analysis of incoming waste to three different dumping yards. These results became base for upcoming waste to energy plant.
Mars Group has developed a cost effective collection and transportation system to collect waste from each door of the municipal area. It has also developed an eco-friendly and cost effective system for Municipal Councils and Corporations which will work for total solid waste management of the township and scientific processing of the waste to convert it into organic compost and Generates Energy from Refuse Derived Fuel.

We feel that Management Handling And Proper Disposal of Municipal Solid Waste is a very important aspect of urban life since it effects the health of Urban Community, Environment and overall Aesthetic View of the City.
Improper management of MSW leads to health hazards as open dumps act as breeding place for rodents, flies and other disease vectors. Studies in the Country and else where has established that 22 human diseases are related to improper management of solid waste.
Open dumps release huge quantities of methane gas into the environment and it is established that it has 21 times more potency to create Green House effect than carbon-di oxide.
The Municipal Solid Waste Received at the Processing Plant is non segregated heterogeneous mass, containing the biodegradable horticulture waste, paper, plastic, metals, drain silt demolition debris, road sweeping and moisture.
For proper processing, therefore, segregation of mixed waste in various fraction is very important. The moisture causes the waste to form lumps there by restricts the screening process and during rains it becomes almost impossible to screen the wet mass of municipal waste.
To counter the effect of moisture we have developed a drier plant to suit are requirements.
The dried waste in conveyed to a two stage Ballistic Separate which effectively segregates the municipal waste into there distinct port the heavy traction containing demolition debars, glass and plastic bottles & metals the biodegradable fraction contain kitchen waste, vegetable and fruit waste and the lighter traction containing linen, polyphone and paper contents.
The biodegradable is then arranged into windrows for composting while part of it is used for generation of through the methane generating pilot unit developed by us.
The windrows are turned periodically-preferably every 7th day- for proper aeration, maintaining of temperature within limits of 55-60 deg. C and to regulate the moisture content in the range of 50-55%.
After 28 days the compost becomes sufficiently mature. At this stage the windrow is broken and the compost is stored for curing and to reduce the water content.
The cured compost is then screened through a set of coarse (35&16mm) and fine screens (14&4mm)screens and the screenings are passed through air classifier to remove glass pieces and other form of inert material including silt. The end product is a fine dark brown humus like compound which after blending is packed for sale.
The lighter fraction obtained from the ballistic separator is conveyed into a set of shredders which cut and convert the fed material into small sizes suitable for use in Boilers and furnaces as a fuel. This fraction of MSW is called “Refuse Derived Fuel” (RDF) and has calorific value ranging from 3200-4000 K.Cal/Kg of RDF, depending upon the quality of MSW.
We have developed and modified the available technologies to suit the use of RDF in boilers for generating steam at adequate temperature and pressure needed for running of turbines.
Presently we are useing our technique in the 2.5 MW power plant in Barabanki, 6,0 MW Power Plant in village-Tofapur, Lalru Distt. Mohali, Punjab, & 6.0 MW power plant in Nasik.
Fuel requirement at 6.0 MW is estimated to be 180 TPD of RDF while the same at the Barabanki plant would be 75 TPD .
