This webinar will have 2 presentation. In the first presentation, Professor Sumathi Sethupathi discussed about the potentail of recovered water pollutant as nutrient. She emphasized that in certain cases, some pollutants can indeed be reclaimed or repurposed as nutrients for various applications such as in aquaculture systems or hydroponic setups, providing essential nutrients for fish or plant growth. Nutrients like nitrogen and phosphorus from various sources such as human waste, detergents, and agricultural run-off. Advanced treatment processes can recover these nutrients from wastewater for reuse in agricultural fertilizer or other applications. Efforts in resource recovery and nutrient recycling from wastewater align with the principles of a circular economy, aiming to reduce waste and maximize the utility of resources within a closed-loop system. However, the feasibility and safety of reusing recovered pollutants as nutrients depend on careful evaluation of the specific contaminants, treatment methods, and the intended end-use applications.

In the second presentation, Professor Eko Siswoyo presented a topic on the development of an innovative low-cost adsorbent based on waste materials for removal of heavy metal ions in water. He mentioned about creating low-cost adsorbents from waste materials for heavy metal ion removal in water is an innovative approach with environmental and economic benefits. Developing low-cost adsorbents from waste materials for heavy metal removal involves multidisciplinary efforts encompassing material science, chemistry, environmental engineering, and economics. The success of such endeavours often lies in innovation, optimization, and practical applicability.
