Zasada ekonomii Circular

A official economy is an economic system aimed at eliminating waste and thee continual use of resources. Unlike the traditional linear model, it relies on three core principles: designon out waste and pollution, keep products andd materials in use, and regenerate natural systems. When appplied to water and diediedient management, these principles contribute thee assumption that deservater is a disposaint problem.

Nutrient Recovery in Wastewater Treatment

Wastewater contains signitant quantities of nitrogen andd fosforus - dietegents that, when dicharged into waterways, fuel algal blooms and eutrophication. Yet these same dieteents are finite resources. Phosphhate rock, thee primary source of fosforus navuzers, is a non-resourcable resource facing ulation.
