Utilization of industrial CO2 emissions by matching the supply and demand potential within industrial collaboration/symbiosis in a Swedish region
(English)Manuscript (preprint) (Other academic)
A substantial amount of research is being done on environmental problems spotlighting climate change, ozone depletion and global warming caused by greenhouse gases (GHG) in general and CO2 emissions in particular. To tackle the problem a variety of reduction/prevention/utilization measures and approaches such as end-of-pipe technologies and proactive solutions are available. Collaborative pathways such as Industrial Ecology/Industrial Symbiosis (IE/IS), the core intention of which is engaging and collaborating in industrial activities toward minimizing waste, circular economy, resource efficiency, and “win-win” business opportunities, is approved as a proactive approach toward sustainable development. This article is about industrial CO2 emissions, specifically utilization of industrial CO2 emissions in Östergötland County in Sweden by matching the supply and demand potential through industrial collaboration. To do this, several steps are taken. First, the paper introduces several different pathways and approaches for combating the issue together with a short description of each. However, the approach of balancing the supply and demand potential in a collaborative and sustainable pathway such as industrial symbiosis will be the core of the paper. Then a description of IS together with a few worldwide practical and operational examples of industrial symbiosis leading to mitigating CO2 emissions is presented. In the next stage, which forms the empirical part of the paper, an attempt is made to map and enhance the potential of industrial CO2 emissions (supplying segment) together with the demand market. On the supply side, an inventory of the major regional emitters, including their respective industries and municipalities, the amount of CO2 emissions in “biogenic” and “fossil” scenarios, the processes involved (incineration/combustion, fermentation, gas cleaning) and types of resources (renewable [biomass] or fossil) used are presented, while from the demand side the average amount of required CO2 in a Scandinavian perspective is given. Matching the total supply and demand potential revealed a major mismatch between the segments in which total country requirement can be fulfilled within just a small fraction of the regional supply.
