SRF - SOLID RECOVERED FUEL. A FOSSIL FUEL REPLACEMENT WHICH HAS CALORIFIC VALUE OF BETWEEN 17 AND 22 MEGA JOULES PER KILOGRAM. SRF IS PREPARED FROM NON-HAZARDOUS COMMERCIAL AND INDUSTRIAL WASTE MATERIALS (I.E. MATERIAL FROM BUSINESSES, SHOPS, STORE PREMISES ETC. A TYPICAL SRF INPUT COMPOSITION CONSISTS OF WASTE PAPER, PLASTICS, TEXTILES, AND RUBBER. THE INPUT MATERIAL IS STRICTLY MONITORED AND ALL NON-ACCEPTABLE ITEMS LIKE METALS/ORGANICS/INERT MATERIAL ARE REMOVED. THIS ENSURES THAT THE COMPOSITION IN THE FINAL PRODUCT IS STRICTLY MADE UP OF ONLY THE COMBUSTIBLE PARTS (AS MENTIONED ABOVE) AND FREE OF COMPOSTABLE MATERIAL. THE MATERIAL IS THEN PROCESSED THROUGH A NUMBER OF STAGES TO END UP WITH A 0.30 MM SIZE PARTICLES READY FOR TRANSPORT. THE PRODUCT IS WRAPPED UP IN PLASTIC TO ENSURE SAFE AND EFFICIENT TRANSPORT. THE RESULTANT PRODUCT THUS IS A HIGH CALORIFIC VALUE MATERIAL WHICH CAN BE USED AS AN ALTERNATIVE FUEL IN PLACE OF COAL IN PRODUCTION OF CEMENT, LIME AND OTHER MATERIALS.APPROVED MATERIAL IS THEN FED INTO A SLOW SPEED SHREDDER FOR PRIMARY PROCESSING. THIS SHREDS THE MATERIAL TO A MAXIMUM SIZE OF 300 - 400 MM. THE SHREDDED MATERIAL THEN PASSES THROUGH A TROMMEL WHERE ANY MATERIAL LESS THAN 60 MM OR GREATER THAN 300 MM WILL BE REMOVED. AN AIR CLASSIFIER IS THEN USED TO ELIMINATE ANY LIGHT OR HEAVY MATERIALS FROM THE STREAM. FOLLOWING THIS, THE MATERIAL WILL PASS THROUGH VARIOUS SCREENING PROCESSES TO REMOVE POTENTIAL CONTAMINANTS; THIS INCLUDES A FE-SEPARATOR AND A NE-SEPARATOR TO REMOVE ANY METAL PRESENT IN THE STREAM, AS WELL AS A PICKING CABIN TO REMOVE ANY ALUMINIUM AND PVC. THE MATERIAL THEN PASSES THROUGH A HIGH SPEED SHREDDER WHICH REDUCES THE SIZE OF THE MATERIAL TO A 0.30 MM PRODUCT. THE SRF IS THEN BALED AND WRAPPED IF FOR EXPORT, OR KEPT LOOSE READY FOR LOADING IN THE DOMESTIC MARKET.

COMBUSTIBLE WASTE (REFUSE DERIVED FUEL) NON-HAZARDOUS WASTE. MADE FROM NON-HAZARDOUS COMMERCIAL AND INDUSTRIAL WASTE AND IS PRODUCED BY MATERIAL RECOVERY FACILITIES (MRFS), USED FOR AUTOMATED AND MANUAL SORTING OF THE WASTE. DURING THE SORTING PROCESS, ALL RELEVANT RECYCLABLES ARE REMOVED FROM INCOMING WASTE (RECYCLABLE PLASTIC, PAPER, CARTON, WOOD, METALS, GLASS,TILE, CONCRETE, ETC). ORGANICS (BIODEGRADABLE MATERIAL) AND FINES (SMALL PARTICLE SIZE FRACTION CONTAINING MOSTLY COMPONENTS NOT SUITED FOR ENERGY RECOVERY) ARE ALSO REMOVED FROM THE INCOMING WASTE.

REFUSE DERIVED FUEL (RDF). PAPER & PLASTIC FRACTION (PPF). THE PRODUCTION OF RDF INVOLVES THE MECHANICAL PROCESSING OF A MATERIALS RECYCLING FACILITY USING SCREENS, SHREDDERS AND SEPARATORS, TO RECOVER RECYCLABLE MATERIALS AND TO PRODUCE A COMBUSTIBLE PRODUCT THAT IS USED IN CEMENT KILNS AND POWER STATIONS. IT CONSISTS OF MAINLY LOW GRADE PLASTICS WITH AN ELEMENT OF PAPER AND CARDBOARD. MATERIALS THAT ARE NOT PRESENT ARE ORGANICS, AND INERTS SUCH AS SAND GLASS & STONES.

PRODUCT IS USED BY POWER GENERATOR COMPANIES AS A FOSSIL FUEL REPLACEMENT. FULE CONSISTS OF WASTE STREAM CONTAINING 90% PLASTIC WITH HIGH CV HEATING VALUES. MATERIAL IS PRE TREATED THROUGH MRFS PRE SHREDDERS, SCREENS, AIR SEPARATORS, METAL SPERARATION, OPTICAL SENSORS / PICKING LINES TO REMOVE WOOD. RUBBLE, PVC AND HARD PLASTICS THAT CAUSE HIGH CHLORINE LEVELS. FINAL MATERIAL IS SHREDDED WITH A SECONDARY SHREDDER TO REDUCE SIZE TO SUB 40MM FLOCK. END PRODUCT IS THEN ANALYSED TO CHECK QUALITY MEETS SPECIFICATION, GENERALLY 18-20MJ, ASH LESS THAN 15% AND CHLORINE LESS THAN 1%. THIS IS THEN SUITABLE AS A HIGHGRADE FUEL FOR KILNS REQUIRING A FOSSIL FUEL. THE PRODUCT IS THEN BALED AND WRAPPED. MATERIAL IS COMPRISED 90% PLASTICS AND 10% WOOD, PAPER AND CARDBOARD.
