The imperative to mitigate climate change necessitates a reduction in carbon dioxide (CO2) emissions. To address the pressing need to mitigate climate change, a systemic and organic approach is essential, leveraging the opportunities that arise from linking different sectors and technologies. This thesis aims to describe an Integrated System consisting of an anaerobic digester, a slow pyrolysis reactor, and an electrolyser, all with the primary objective of producing syngas. The system includes the process of converting syngas into methanol. The main scheme takes its cue from an actual plant, under construction in Denmark, by Stiesdal SkyClean, a branch of the Stiesdal company.
