Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study investigates the rheological behavior of industrial phosphoric acids (H3PO4) produced at the JORF–LASFAR phosphoric plant in Morocco, with P2O5 concentrations of 18%, 29%, 42%, and 54%. Rheological measurements were performed using a rotary cylinder rheometer over a shear rate range of 1–1000 s−1.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, EarlyView.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Biostimulants are increasingly used in agriculture to promote plant growth, improve stress tolerance, and support sustainable farming practices. One common method of production is chemical hydrolysis of protein‐rich waste, such as tannery by‐products, offering an economical and eco‐friendly alternative to conventional raw materials.

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 ...
