Decision support tool for collection and treatment of source-sorted organic municipal solid waste

image of Biowaste

Waste management strategies focus on waste minimization and on better utilisation of the resources in the waste in all the Nordic countries. Better handling of municipal waste is in focus, as it is a significant waste fraction with many unused potentials. A tool for support of local decisions about handling of the municipal organic solid waste has been developed in order to cover the spectrum of technological solutions available today and further include the local conditions and priorities in the Nordic countries. The tool focuses on the most important environmental aspects without losing the national or global perspective. Further the tool is kept simple in order to secure that the necessary information can be provided locally.



Combined digestion and composting

Some biological treatment plants combine anaerobic digestion with composting, either in the same reactor or as a combination of anaerobic digestion followed by e.g. windrow composting. This module is a combination of the composting module and the biological treatment module. Different technologies combining anaerobic digestion and composting can be modelled. Energy consumption, degradation ratio and control of air emissions depend on the technology level and the physical features of the plant.
