Showcase āP-labā: urban raw materials in a small-scale circular economy
Urban food and material chains contain huge amounts of valuable materials, a considerable proportion of which is still lost as waste. Take phosphorus for example, an indispensable and irreplaceable nutrient. Whilst the global supplies of phosphates contained in ores are steadily diminishing, we all excrete them in our urine where they return to the environment via sewers, mixed with other substances. Researchers from TU Delft demonstrate an alternative in the sea container.
