What is waste-to-value?
Short answer
Waste-to-value is the recovery of useful materials, energy, or products from discarded streams. Examples include sorted recyclables, heat from combustion, and biogas from digesting organic waste.
Start with the waste stream
Identify its composition and what can still be prevented, reused, or recycled. In the U.S. EPA hierarchy, energy recovery sits below source reduction and recycling and above treatment and disposal.
Follow the output
Ask what leaves the facility, its quality specification, and who takes it. A plant that produces raw biogas serves a different market from one that upgrades it to pipeline-quality fuel.
