The portion of the coal which cannot be grinded finds its way to mill reject.The paper mill which use recycled paper as the raw material generate paper mill reject (PMR) in the range of about 5-10 . PMR has a high calorific value with low ash and sulfur contents, generally. Processing of PMR into pellet forms as boiler fuel to reduce the use of coal or other fossil fuels has not been done, yet. PMR pellets and coal was mixed in the ratio of 5 PMR and 95 coal (C95R5.
