These include water, energy, fertilizers, biofuels, biopolymers, and critical minerals.

This type of resource recovery has thrived, primarily in higher-income countries, as part of established efforts relating to general wastewater treatment. However, their uptake in the power industry has suffered setbacks, given complex water quality. Still, several research and development efforts in recent years suggest promise.
