Landfilling is the disposal fo solid waste that cannot be economically reused or recycled or incinerated for energy recovery. Landfills are lined with impermeable materials to prevent leachates from polluting groundwater.

Advantages:- Relatively inexpensive.Wide range of contaminants and material can be disposed off. Contaminants are completely removed form the site. Permits rapid remediation of site. By proper landfilling ground water, surface water and air pollution can be prevented. Cleaner environment and city beautification. Land reclamation.


Composting is an aerobic/facultative biodegradation of organic materials to produce nutrient rich compost. It is the way to recycle your yard and kitchen wastes, and is a critical step in reducing the volume of garbage

Advantages:- Cost effective implementation. Environmentally sound- Natural recycling of organic materials. Nutrient value of compost material. Provides nitrogen, phosphorus, potassium, sulfur and micro-organisms that are essential for plant growth. Utilize existing facilities when available. Prevents the production of substances responsible for atmospheric pollution which are otherwise produced if this matter is burned. Reduces landfill burden.



Biomethanisation is a biological process in which the organic matter is decomposed by anaerobic organisms, producing methane gas as the major by product (60%) and CO2 (approx. 40%)

Advantages:- Less area as it is compact system. Minimum mechanism required for system operation. Biogas produced is substitute to carbon fossil fuel. Water produced can be used for irrigation. Power generation from biogas



Refused derived fuel is the segregated high fraction of processed Municipal Solid Waste. Often in pellets form it is produced from combustible elements of household and commercial waste, and used in industrial boilers to produce energy.

Advantages:- Dehydrates and forms municipal solid waste into small pellet’s. Easy transportation, storage and combustion stability. Good quality fuel from waste. Power generation. Calorific Value of RDF: 3000 – 3500Kcal/Kg.



Gasification is the chemical conversion at high temperature of material containing carbon atoms into synthetic gas.  The gas may consist of carbon monoxide, hydrogen and methane also known as synthetic gas (Syngas).  This syngas can be used to manufacture chemicals and can be used as fuel in place of natural gas for power generation.

Advantages:- Power generation from Syn gas. Can also generate steam which can be used of industrial applications. Destruction effciency is 99.9%. Air emission below standard.
