摘要： A method of valuation of raw fines materials, comprising selectively screening, biotreatment or composting of raw fines materials or selection as fillers in composites. The method comprises screening the raw fines materials to Grade 1 comprising fines materials of a size of at most about 5 mm and Grade 2 comprising fines materials of a size larger than about 5 mm; and at least one of: A) bio-oxydating organic contaminants of the Grade 1; by adding and mixing organic amendment under controlled temperature, nutrients content and water content conditions and monitoring a content of organic contaminants until the content of organic contaminants stops decreasing; and B) composting the Grade 1; by adding and mixing organic amendment under controlled temperature, nutrients content and water content conditions, and monitoring pathogens content and respiration rate; and stopping the addition of organic amendment upon detection of absence of pathogens at a predetermined respiration rate.
