Mechanical-Biological Treatment (MBT) is a pretreatment method used before landfilling to reduce the amount of waste to be disposed.3 MBT literally means the combination of mechanical crushing and sorting processes and biological treatment (e.g. aerobic and anaerobic decomposition) (Fig. 2). The advantage of MBT in terms of appropriate waste management is that it can be applied to mixed domestic solid waste without systematic segregation. An MBT facility can incorporate a number of different processes in a variety of combinations for a wide range of purposes

This guideline focuses on MBT technology for Municipal Solid Waste (MSW), mainly household waste and commercial waste, in urban areas of Asian developing countries.1 The guideline aims to assist decision-makers and policymakers at the national and city levels and other stakeholders, such as energy plants, as well as manufacturing industries that are seeking sources of alternative fuel, to evaluate the feasibility of introducing MBT technology as an appropriate strategic option for improving waste management. This guideline will: (1) provide a holistic understanding about MBT technology including both advantages and disadvantages, as well as information about the technical and non-technical aspects of planning a sustainable MBT facility, and (2) propose key evaluation criteria and a precheck flow in the decision-making process to objectively determine and evaluate criteria when considering the potential of introducing MBT technology.
