Each presentation was followed by Q & As and moderated discussion. While the proceedings were held under the Chatham House Rule, key outputs and observations included:

  • A variety of country-specific motives for examining the FWD option included reduction of landfill, a desire to increase biogas production for heat, electricity and fuel, ease of capture of uncontaminated food waste and high costs of food waste collection and transport to treatment.
  • There was no evidence of FWDs causing or increasing sewer blockages and the majority of other common concerns proved unsubstantiated. FWDs were not found to contribute to FOG, H2S or vermin and there was negligible change in water use.
  • Ground egg shell was noted in the Lulea cctv images, but had not proved a blockage issue in Surahammar or Smedjebacken. It was suggested that egg shells are visually identifiable but not especially significant particulates. The inspections took place at low flow and it is likely that successive higher flows transport the particles along the sewer.
  • Municipal trials in the United States had noted a 33% reduction in residual waste. It is hoped that the UK Local Government Association FWD Trials may provide further insights into consumer behaviour with regard to waste reduction.
  • Denmark and Italy demonstrated a keen interest in enhanced nitrogen and phosphate removal because of the additional carbon and the speakers suggested that new WwTP technology should seek to address this even more effectively.
