The 2007 Clarke Lecture
"Undiminished growth in the world’s population and the spread of industrialization to former agricultural societies have put relentless pressure on resources for food and fuel, as well as on rejected energy in the form of plant nutrients that can seriously pollute receiving waters. This paper will look at the causes of deterioration of the water environment and how plant nutrients can be recovered while solving many pollution problems.
Proteins can be recovered from wastewater to augment food supplies, urine can be separated and used as fertilizer, phosphorus can be recovered and used in fertilizers or incorporated in compost, algae can be grown and harvested for converting to biodiesel fuel, wastewater biosolids can be turned into organic fertilizers, and water can be reclaimed for reuse, which would prevent the deterioration of receiving water quality."
