Mapping and Innovating Business Models of Food Hubs in Short Food Supply Chains

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Short food supply chains (SFSCs) offer sustainable alternatives to conventional food systems (CFSCs) but require effective intermediaries to scale and remain competitive. Food Hubs (FHs) serve this role by enhancing SFSC efficiency and market reach while upholding community‐oriented values. However, limited research has examined how FHs design

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

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.
