Nanomaterial disposal by incineration

Environ. Sci.: Processes Impacts, 2013
As nanotechnology-based products enter into widespread use, nanomaterials will end up in disposal waste streams that are ultimately discharged to the environment. One possible end-of-life scenario is incineration. This review attempts to ascertain the potential pathways by which nanomaterials may enter incinerator waste streams and the fate of these ...

Bio‐Inspired Cascade Photocatalysis on Fe Single‐Atom Carbon Nitride Upcycles Plastic Wastes for Effective Acetic Acid Production

Advanced Energy Materials, EarlyView.
This work demonstrates a novel cascade photocatalysis concept using Fe single‐atom catalysts (Fe@C3N4 SAC) to directly upcycle plastics (PET, PP, PE, PVC) into valuable acetic acid at ambient conditions. Inspired by microbial degradation, the bifunctional cascade photocatalyst combines Fenton‐like oxidation and CO2 photoreduction, as validated by ...

Stage‐Specific Roles of Deep Eutectic Solvents in Recycling of Spent Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Deep eutectic solvents (DESs) offer tunable acidity, redox, and coordination properties for selective recycling of spent lithium‐ion battery cathodes. Through co‐dissolution, single‐ and two‐metal separations, DESs enable sustainable recovery of critical metals for closed‐loop regeneration of battery‐grade materials, advancing a circular economy for ...

Synergistic Effects of Electricity and Light for Efficient Iron‐Catalyzed Recycling of Polystyrene Waste

Angewandte Chemie International Edition, EarlyView.
The synergistic interplay of electricity, light and earth‐abundant, nontoxic iron catalysis allowed for the efficient recycling of post‐consumer polymers into value‐added products. This robust depolymerization strategy was viable on multigram‐scale, where the cathodic hydrogen evolution reaction presents an attractive opportunity for a green hydrogen ...

Baseline Characteristics of Pristine Agricultural Pods Biochar

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The valorization of agricultural pod wastes into biochar offers a sustainable pathway for waste management and the development of functional carbonaceous materials. This study comparatively evaluates biochars produced from cocoa, flamboyant, and locust bean pods using an autothermal top‐lit updraft gasifier with retort heating, a system ...

Rhodamine B Adsorption Efficiency of Biochar Produced Through Co‐Pyrolysis of Municipal Sewage Sludge and Food Waste Mixture Under High‐Temperature Condition

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT With the large‐scale construction of wastewater treatment facilities, the production of municipal sewage sludge continues to rise. This sludge contains substantial amounts of toxic and hazardous substances, and improper disposal may lead to secondary environmental pollution.
