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