Norwegian Institute of Bioeconomy Research (NIBIO) has completed research indicating that recycled food waste may contain pharmaceutical residues.
- In addition to pharmaceutical residues, higher concentrations of per- and polyfluoroalkyl substances (PFAS) were found in biogas digestate from sewage sludge compared to that from food waste.
- PFAS are man-made chemicals used in products such as Teflon pans and water-repellent textiles.
- The per-and polyfluoroalkyl substances (PFAS) are a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water.
- Many PFAS are a concern because they: do not break down in the environment, can move through soils and contaminate drinking water sources, build up (bioaccumulate) in fish and wildlife.
- Some PFAS may affect human growth and development.
