Securing a safe water supply for Earth’s growing population is a global goal that is reflected in the long-term sustainability plans of almost every nation. Creatively solving this problem is another matter altogether. University of Saskatchewan graduate student Bernd Steiger is using chemistry expertise and Saskatchewan-based waste to soak up contaminants in fresh water reserves. “This province can be considered the breadbasket of Canada with its large agricultural sector,” Steiger noted. “Agro-waste (such as the inedible part of a plant, for example) is a low-value byproduct of agriculture, and turning this waste material into specialty adsorbents can aide in generating additional wealth for the Sask. agro-economy, while also serving to address water security and sustainability goals.” Steiger’s work uses several principles of what is referred to as ‘green chemistry’ — a type of chemistry that avoids a need for conventional chemical or energy inputs.
