ICC Group is developing a waste to energy process based on gasification technology. The Municipal SolidWaste is received at the Material Recovery Facility (MRF), where the non-combustible portion of the waste isremoved. The remaining 77% of the material has 24% moisture content. The material is dried with waste heatfrom the power plant to 15%. The loose and shredded material can't be used in the existing updraft gasifier.The feed stock should be pelletized or briquetted. The fixed carbon content of the feedstock after densifying is8.8% which is very low for the gasification process. Thus, it's needed to mix the densified fuel with wastewood to increase the fixed carbon content to at least 15%. The objective is to test the Refused Derived Fuel(RDF) and to investigate parameters involved in making durable pellets from these residues. ICC Group is alsoin need of determining the physical and compositional characteristics of the pellets, as well as in-batch andbatch-to-batch reproducibility. Thus UBC will conduct a series of pelletization tests with different mixturerecipe, pre-conditioning of material as well as adding binders. The produced pellets will then be tested for theircalorific value, chemical composition, chlorine content and ash content. The produced pellets will then betested for durability and hardness. This initial collaborative research and development between ICC Group andUBC is aimed at establishing a long term research partnership for optimizing the entire continuous process linefor making durable pellets from Refused Derived Fuel (RDF).
