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).

ICC集团正在开发一种基于气化技术的垃圾转化为能源的过程。城市固体废物在材料回收设施(MRF)接收，在那里废物中的不可燃烧部分被移除。其余77%的材料具有24%的水分。用发电厂的余热将材料烘干至15%。现有的上风式气化炉不能使用松散、破碎的原料，原料应进行造粒或成型。密化后原料的固定碳含量为8.8%，对气化工艺来说是很低的。因此，需要将致密燃料与废木混合，以将固定碳含量提高到至少15%。目的是测试被拒绝的衍生燃料(RDF)，并调查用这些残留物制造耐用球团所涉及的参数。ICC集团还需要确定颗粒的物理和成分特征，以及批次内和批次间的重复性。因此，UBC将使用不同的混合物进行一系列造粒试验，包括配方、材料的预处理以及添加粘结剂。然后将对生产的球团矿进行热值、化学成分、氯含量和灰分含量的测试。然后，生产的球团将具有更好的耐用性和硬度。ICC集团和UBC之间的这一初步合作研发旨在建立长期研究伙伴关系，以优化整个连续生产线，从废弃的衍生燃料(RDF)中制造耐用的球团矿。
