Energy Crisis and Pakistan Energy is considered to be life line of any economy Energy is pivotal in running machinery in factories and industrial units In Pakistan During 2009-10, Energy supply witnessed a decline of 0.64 %. Pakistan needs around 15,000 to 20000 MW electricity per day and there is a shortfall of about 4000 to 9000 MW per day
Energy Crisis and Pakistan Resources of EnergyPetroleum products• In 2009-11, consumption of petroleum products was 35% of total share of energy.Natural Gas• Average production of natural gas is 4,048.76 million cubic feet per day and there is an increase of 1.56 percent.Coal• Coal is primarily being used in brick kiln and cement industries• Approximately 67 percent coal is imported because indigenous coal is not considered of good quality.
PAKISTAN “A DUMPING GROUND”• There is no proper waste collection system.• Waste is dumped on the streets.• There are no controlled sanitary landfill sites.• Citizens are not aware of the relationship between ways of disposing off waste and the resulting environmental and public health problems.Effects of Waste• Health Hazards• Ground water pollution• Air pollution

What is RDF?Refuse-derived fuel (RDF) is a fuel produced by shredding anddehydrating Solid waste (MSW) with a Waste Convertertechnology.Why RDF?RDF fuel pellets ranges from 75% to 85% of Coal used forelectric power generation.The emissions of RDF are less harmful than Coal.Coal contains approx. 70% carbon while RDF contains 52%carbon.Sulphur contents of RDF are lower than Coal.RDF typically produces 1 kWh for 15460 Btu (2.6 pounds ofRDF).
PRODUCTION OF REFUSE DERIVED FUELSRDF can be produced by processing: MSW (Municipal Solid Waste) Industrial WasteEnd Markets of RDFRDF can be used: To produce electricity Alongside coal in Power Plants In Cement Kiln Industry
