1. Industrial by-products in treatment of metals from polluted water
Abstract : Water treatment can be carried out effectively by passive, low cost methods, as an addition or alternative to existing advanced technology. Energy and resource use can be optimized (i.e. minimized) by reusing by-products from local or regional manufacturing of timber and steel. READ MORE

2. Development of a Low Cost Remediation Method for Heavy Metal Polluted Soil
Abstract : High concentrations of heavy metals in the soils have potential long-term environmental and health concerns because of their persistence and accumulation tendency in the environment and along the food chain. This study was aimed at studying the feasibility of heavy metals removal from the soil using plants naturally growing in the surroundings of selected polluted sites in Tanzania and soil application of the sorbent materials zeolite and autoclaved aerated concrete (AAC).

3. Sludge-derived char : utilisation as a metal sorbent in dilute wastewaters
Abstract : Metal concentrations in soil and water have increased since the Industrial Revolution, which may have negative health and environmental effects. Metal pollution occurs, for instance, in municipal wastewater, industrial wastewater, and stormwater. Concentrations are often low, due to dilution. A common technology for metal removal is sorption.

5. Stabilization remediation of soils contaminated with per- and polyfluoroalkyl substances (PFASs)
Abstract : Per- and polyfluoroalkyl substances (PFASs) are a major global concern in pollution of drinking water sources and aquatic environments. Due to the high persistence and mobility of these compounds, remediation methods for PFAS-contaminated soils are urgently needed to protect the surrounding environment and drinking water source areas.
