What is it?

  1. A paste produced by combining power plant wastewater and coal ash
  2. A new concrete for power plant construction
  3. A product of solar panel recycling

ANSWER:

A

This paste is a product of a process known as encapsulation in which power plant wastewater brines are mixed with fly ash. The flowable paste can be placed in a landfill, where its constituents stabilize chemically and physically. EPRI laboratory and field studies suggest that encapsulation is a potential game-changer for waste management at coal-fired power plants.
