A better understanding of the influence batch to melt conversion has on the total energy consumption of a glass melting furnace is one of the necessary conditions needed to design batches that can be melted with less energy. Based on targets defined in the Dutch roadmap 2030 and the British Glass Decarbonisation roadmap 2050, CelSian, the Dutch Enterprise Agency organised an Expert workshop in 2015. The outcome of the presented papers and discussions is used to define a project proposal for an international research project. The aim of the project is to develop a methodology to characterize batches in relation to their contribution to the energy consumption of a real melter. This paper gives an overview about the approach to the expert workshop, the outcome of the workshop and describes the project proposal in a nutshell. Interested parties are invited to participate in the project to join forces for a greater success of the research work. Please contact: sven-roger.kahl@ardaghgroup.com
