Rigorous process simulation helps in the qualification of direct CO₂ to DMC conversion co-assisted by a catalyst and dehydration agent in GHG emission reduction.

This article discusses the directions for energy systems based on an urgent proposal to counter the energy crisis in eastern Japan, published from the Society of Chemical Engineers, Japan. We first illustrate the situation Japan faces, highlighting the urgency and seriousness of the consequences of power outages in industry and daily life. Then, we elaborate on the necessity for policy support to trigger collective actions to temporarily practice countermeasures that would not necessarily save r

For sustainability, it is necessary to consider potential life-cycle environmental impacts during the early stage development of key technologies. In this study, ways to address the intractable problem of recycling polyvinyl chloride (PVC) waste were considered by a combined approach including experiments, simulations, and an ex ante life-cycle assessment (LCA). The potential life-cycle environmental impacts of an industrial-scale Cl recovery process, including the dechlorination of PVC by ball-

Purpose This paper aims to suggest the structure of a platform for education and capacity building for Future Earth, which is an intensive program open to the eight stakeholders and which utilizes existing research programs/facilities associated with Future Earth. An intention of this paper is to facilitate a policy brief for projects associated with Future Earth. Design/methodology/approach This paper reviewed backgrounds and necessary items for education and capacity buildings in Future Earth

The dechlorination (de-Cl) process for polyvinyl chloride wastes not only removes chlorine (Cl) that is undesired in the subsequent thermal treatment but also potentially establishes a Cl cycle that avoids NaCl production. Because the de-Cl process utilizes a mixture of sodium hydroxide (NaOH) and ethylene glycol (EG), the recovery of both Cl ions and EG is practically necessary for economic and environmental reasons. Designing an electrodialysis (ED) process that can recover Cl ions and EG from

Introduction of photovoltaic (PV) systems, also known as solar cell systems, reduces greenhouse gasses (GHGs) emission, by substituting a part of the GHG intensive generation with GHG-free generation during effective daylight hours. Because power is generated from different kinds of power plants operated with momentarily changing proportion, consideration of resulting changes in the power mix is needed to correctly estimate the reduction potential of a large scale introduction scenario. In this

To achieve higher energy security and lower emission of greenhouse gases (GHGs) and pollutants, the development of renewable energy has attracted much attention in Taiwan. In addition to its contribution to the enhancement of reliable indigenous resources, the introduction of renewable energy such as photovoltaic (PV) and wind power systems reduces the emission of GHGs and air pollutants by substituting a part of the carbon- and pollutant-intensive power with power generated by methods that are
