Waste recovery and disposal are one of the biggest management challenges. An adequate waste management design is critical in contributing to the development of a sustainable circular economy. There is a need for a systematic and preferably graphical approach to assessing the emissions associated with waste treatment processes followed by strategies for mitigation. This study aims to propose a graphical approach in identifying the appropriate waste management system (WMS) with lower emissions. The proposed graph-based approach termed as Extended-Waste Management Pinch Analysis (E-WAMPA) is an extension to the existing WAMPA. It is distinguishable by three major issues a) Emission intensity of WMS (Net GHG per capita) and stagewise algorithm aims for regional waste management planning are introduced, b) the emissions of recycling are not assumed as zero c) The demonstration is based on the defined targets, projection and power grid mix of EU. A generic methodology of E-WAMPA is presented and followed by the European Union- 28 member states (EU-28) case study to elucidate the application. The considered waste type is the municipal solid waste (MSW), and the assessed emission is GHG. E-WAMPA is capable of suggesting the strategies in fulfilling the targeted emission reduction of a region (e.g. 10 % reduction) and meeting the individual treatment targets. One of the possible strategies is demonstrated on adjusting the WMS of Malta, Greece, Cyprus and Romania. The way forward of E-WAMPA have been discussed as well.
