Life cycle analysis for the cultivation and combustion of miscanthus for biofuel compared with natural gas [PDF]

, 2008
As negative environmental and economic impacts of fossil fuels have escalated, so has the importance of renewable bioenergy crops whose feedstocks are noncompetitive with food supplies. Compared with fossil fuels, use of lignocellulosic feedstocks offers

Socioenvironmental implications of Jatropha curcas cultivation for biodiesel supply in postmining communities

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The long‐term viability of Jatropha curcas as a biodiesel feedstock has been widely debated. Many early initiatives failed to deliver consistent economic returns despite promising environmental attributes. This study re‐evaluated J. curcas‐based systems within an integrated environmental–economic framework, focusing on their potential role in ...

Life cycle assessment of biodiesel synthesis from waste cooking oil using bifunctional heterogeneous catalyst

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The development of renewable energy sources is important in order to achieve the United Nations Sustainable Development Goals (SDGs). Waste cooking oil (WCO) is a promising feedstock for biodiesel production through transesterification. Heterogeneous bifunctional catalysts offer a sustainable alternative to conventional homogeneous bases such ...

Potassium hydroxide activation of microalgal biochar for improved adsorption efficiency

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Activated carbon was prepared from Chlorella by carbonization and potassium hydroxide activation, and its structural properties and methylene blue (MB) adsorption performance were evaluated. Raw Chlorella exhibited an adsorption capacity of 287.2 mg g−1, which decreased to 214.8 mg g−1 after carbonization.

Evidence to support integrating feedback best practice for computer‐based assessment in pharmacology education

British Journal of Clinical Pharmacology, EarlyView.
Feedback is the most powerful driver of learning, but it can afford variable effects depending on the method used. The design of feedback for computer‐based assessment—now increasingly prevalent in higher education—remains relatively underexplored, particularly for pharmacology education.

Rebound Effects in Circular Manufacturing: Overview of Potential Rebound Mechanisms Activated by Circular Strategies Across Key Business Processes

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular economy (CE) is increasingly adopted by the manufacturing industry to decouple economic growth from environmental impacts by optimizing resource use and minimizing waste generation. Nevertheless, circular manufacturing often triggers systemic responses that diminish or offset their potential environmental gains, resulting in the so ...
