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.

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Sustainable Upcycling of Office Waste Paper Into Cobalt/Carbon Aerogels for Highly Efficient Microwave Absorption

Electron, EarlyView.
Co/C aerogels (Co/CAs) are successfully fabricated with office waste paper (OWP) as the raw material by loading ZIF‐67 crystals. The optimal sample exhibited an effective absorption bandwidth of 5.6 GHz, which outperforms many biomass‐derived microwave absorbing materials.

Biogas upgrade using modified natural clay

Energy Conversion and Management: X, 2021
The pollutants in biogas reduce its calorific value and limit its application in machines by causing corrosion and wear in metallic parts. The commercial technologies of biogas upgrade are expensive for small digesters. Natural adsorbents present cost-effective and locally available materials for purification of biogas but the process has not been ...

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.
