Municipal Solid Waste Physical & Chemical Composition
Physical fraction sorting (Biodegradables, Plastics, Paper, Inert, Textiles, Metals, Glass) and chemical proximate/ultimate analysis for municipal corporations and waste processing concessionaires.
Proximate Analysis
Moisture content (%), Volatile matter (%), Fixed Carbon (%), and Ash Content (%) as per ASTM D3172 standards.
Isoperibol Bomb Calorimetry
Refuse-Derived Fuel (RDF) Gross Calorific Value (GCV)
Precision Bomb Calorimeter testing to determine Gross Calorific Value (GCV kcal/kg) and Net Calorific Value (NCV) of RDF fluffy fraction and compressed RDF briquettes supplied to cement kilns and power plants.
| Fuel Parameter | Testing Equipment | Cement Kiln Co-Processing Standard |
|---|---|---|
| Gross Calorific Value (GCV) | Isoperibol Bomb Calorimeter (IS 1350) | > 2500 kcal/kg |
| Moisture Content (%) | Hot Air Oven 105°C Drying | < 20 % |
| Chlorine Content (Cl %) | Bomb Combustion Ion Chromatography | < 0.7 % |
| Ash Content (%) | Muffle Furnace 815°C Ashing | < 15 % |
Landfill Leachate Profiling
Landfill Leachate Water Toxicity & Characterization
High-strength wastewater analysis of municipal landfill leachate for BOD, COD, Heavy Metals, Ammonical Nitrogen, and Organics to design leachate treatment plants and MEE evaporators.
Fertilizer Control Order 1985
Organic Compost Quality (Fertilizer Control Order - FCO 1985)
City compost quality testing under FCO standards to qualify compost for commercial fertilizer marketing and agricultural distribution.
