Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...

Enhanced Photocatalytic Antibiotic Micropollutants Removal Resulting From a Synergism Between Cu Single Atoms and Carbon Vacancies on Graphitic Carbon Nitride

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Scheme of the synergistic degradation for antibiotic micropollutants in the Cu/ag‐C3N4 system. Photocatalytic processes driven by visible‐light irradiation offer a sustainable means of micropollutants removal from aquatic environments without the addition of reagents.

Governing Within the Constraints of Carbon Budgets: Regional Insights From Sweden

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Staying within the limits of a rapidly shrinking global carbon budget while avoiding dependency on negative emissions technologies and carbon dioxide removal remains a significant challenge in a multi‐level governance system, where resources and responsibilities are dispersed among different actors.
