Rethinking Chlorine: Essential Chemical or Replaceable Risk?

open access: yesChemSusChem, Accepted Article.
This review critically examines the dual nature of chlorine as both an indispensable base chemical and a potential risk. Chlorine and its by‐product hydrogen chloride play essential roles in the production of pharmaceuticals, plastics, agrochemicals, and disinfectants.

The Fusion of Elemental Sulfur With Waste Cooking Oil‐Based Derivatives: Beyond Renewability

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
The fuse of two waste streams, elemental sulfur and waste cooking oil, is enabled by Inverse Vulcanization. The process might ensure the closed‐loop production of polymeric materials for a wide range of applications, beyond its sole potential renewability.

Clumsy solutions and climate change: A retrospective

open access: yesWIREs Climate Change, Volume 14, Issue 1, January/February 2023., 2023
Clumsy solutions for a wicked world. Abstract In 1989, Steve Rayner chided fellow anthropologists for “fiddling while the world warms.” This was the starting point of a decades‐long application to human‐made climate change of the cultural theory that he had developed with Mary Douglas and Michael Thompson.

Grouping technology and a hybrid genetic algorithm‐desirability function approach for optimum design of cellular manufacturing systems

open access: yesIET Collaborative Intelligent Manufacturing, Volume 4, Issue 4, Page 267-285, December 2022., 2022
Abstract Cell formation and machine layout in cellular manufacturing systems (CMs) design are considered as a crucial, yet hard and complex decision process. Owing to the nondeterministic polynomial time (NP) and combinatorial class of this problem, this paper presents an innovative heuristic approach to re‐arrange machines enabling the minimisation of
