Compost Quality and Sanitation on Industrial Scale Composting of Municipal Solid Waste and Sewage Sludge

Municipal solid waste and sewage sludge are produced in large quantities that often managed through industrial composting treatment. Because of their origin, composition, complexity, ensuring adequate stabilization the organic matter, sanitation fecal contaminants during is utmost significance, difficult to achieve on an scale. In this study, operations six facilities process municipal were evaluated from point view achieved quality compost produced. addition, results compared using model green waste. Differences between plants ascribable other than systems. High phytotoxicity contamination above legislation thresholds found contrast, more stable mature those waste, also had level sanitation. The raw material operational factors great relevance obtain a stable, mature, pathogen-free compost.
