PFAS in Waste Conversion & Energy Recovery

Composting

  • Much heavier concentrations in food packaging --> 10x (Choi et al., 2019)
  • Dominated by shorter-chain
  • Not much research in byproducts of composting
  • Points of exposure: crops vs. lanscaping

Recycling

  • Little research on persistence
  • Occupational exposure (dust)
  • Secondary processing

Waste-to-Energy (WTE)

Typical time/temperature/turbulence conditions in WTE facilities appear to have the capacity to achieve up to 99% destruction of PFAS. On the other hand, insufficient time/temperature/turbulence may result in products of incomplete combustion (PIC), which may further concentrate PFAS compounds.

  • Emissions out of the stack: before/after pollution control
  • Ash

* NEW * Answers to Questions about Treating PFAS with WTE Technologies

Can technologies such as incineration and combustion safely destroy PFAS compounds?
