Revisiting the Carbon Footprint of Single‐Use Technologies in Biomanufacturing: A Bottom‐Up Analysis Reveals a Paradigm Shift

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The biopharmaceutical industry increasingly relies on single‐use technologies (SUT) for operational flexibility. For a long time, SUT was considered more sustainable than stainless‐steel (SST) systems due to water and energy savings. This study re‐evaluates this paradigm via a detailed bottom‐up analysis of the SUT carbon footprint at the 2000

Cluster Analysis of Circular Economy and Industrial Symbiosis Practices and Their Impact on Sustainability Performance in the Plastics Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how plastics manufacturing firms can be classified according to their level of implementation of circular economy (CE) and industrial symbiosis (IS) practices and how such adoption influences sustainability performance. Using data from plastics manufacturing firms, we integrate cluster analysis with partial least squares ...

Upcycling Real‐World Post‐Consumer Polyolefins Plastics Into Light Olefins Via Microwave‐Assisted Processing

Carbon Energy, EarlyView.
Microwave‐driven Ru@α‐Fe2O3 selectively upgrades real‐world post‐consumer mixed polyolefin waste into light olefins with high gas yields and olefin selectivity at markedly reduced temperatures compared with conventional thermal pyrolysis. Strong tolerance of additives and feed heterogeneity highlights an energy‐efficient and scalable route for circular
