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?

PFAS Fate and Transport in Waste-to-Energy Facilities

A new report developed by SWANA's Applied Research Foundation addresses PFAS fate and transport in waste-to-energy facilities.

This report is available free to ARF Waste Conversion and Energy Recovery (WCER) Group subscribers. The report will be available for purchase to SWANA members and the general public in June, 2022.
