Co-application of red gypsum and sewage sludge on acidic tropical soils. [PDF]

, 2011
The agroenvironmental impact of co-utilization of red gypsum and sewage sludge was investigated. Both laboratory and greenhouse studies were conducted. The treatments were soil + sewage sludge (5% w/w) + red gypsum (0, 2.5, 5, 10, 20, and 40%, w/w). Corn

Corn cob pyrolysis: A systematic literature review of methods and applications

The Canadian Journal of Chemical Engineering, EarlyView.
Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

Removal of benzotriazoles from domestic wastewater using Pleurotus ostreatus fungal pellets

The Canadian Journal of Chemical Engineering, EarlyView.
Removal of benzotriazoles from domestic wastewater using a fungal pellet reactor with Pleurotus ostreatus. The system effectively removed CBTR (70%), while BTR (19%), 5‐TTR (17%), and OH‐BTH (16%) showed moderate removal. Abstract Benzotriazoles are a group of persistent and mobile substances commonly found in aquatic environments due to inefficient ...

Synergistic Co‐Pyrolysis of Tannery Sludge and Oyster Shells for Enhanced Chromium Speciation Transformation and Recovery Efficiency

CleanMat, EarlyView.
Oyster shell (OS) as a sustainable calcium source for chromium recovery from tannery sludge via co‐pyrolysis. OS outperformed CaCO3, achieving > 95% Cr recovery, attributed to its organic matrix proteins enhancing adsorption and phase conversion. The oxidation of tannery sludge Cr(III) to Cr(VI) improved recyclability, aligning with circular economy ...
