Anaerobic Digestion and Composting in an Integrated Strategy for Managing Vegetable Residues from Agro-Industries or Sorted Organic Fraction of Municipal Solid Waste

The co-digestion concept to improve the anaerobic digestion of several biological wastes is examined together with the integration of anaerobic digestion and composting biotechnologies. A series of experiments were carried out using the mechanically selected organic fraction of municipal solid waste. The anaerobically digested waste was composted with fresh substrate. The results show that the waste is perfectly stabilized and the pathogen indicators are greatly reduced.
