Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

The effect of pretreatment on VFA production from tofu and tempeh wastewater through anaerobic digestion batch

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Tofu and tempeh, derived from soybeans, are widely consumed for their nutritional value and high protein content. However, the production of these foods generates nutrient‐rich wastewater that poses environmental challenges while offering opportunities for valorization.

Distribution of methanogenic potential in fractions of turf grass used as inoculum for the start-up of thermophilic anaerobic digestion

, 2012
This study aims to investigate thermophilic methanogens in turf used as an inoculum. Results showed that Methanoculleus sp. regarded as hydrogenotrophic and Methanosarcina sp. regarded as acetoclastic methanogens were present in turf tested.

Applying a Systems Thinking Approach to Circular Economy Transitions: Insights From the Use of a Sociotechnical Systems Approach Within the UK Hospitality Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite more than 20 years of research into sustainable tourism, the environmental impact of the UK hospitality sector remains high. A growing body of research into the concept of a circular economy (CE) demonstrates that transitioning to this way of working has significant benefits both for the environment and business outcomes.

Operational Performance Implications of Circular Economy Implementation: An Empirical Exploration in the Manufacturing Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT The global manufacturing sector has increasingly adopted circular economy (CE) practices to address sustainability challenges and improve operational efficiency. This study explores the impact of five CE practices—reduce, reuse, remanufacture, recycle, and recover—on key operational performance dimensions: quality, speed, dependability ...
