Farmfood specializes in recycling various offal from poultry slaughterhouses for specific uses – especially for the pet food industry and biogas plants. Production is continuously expanded. Heat-treated slaughterhouse waste has a distinctive odor that can be difficult to completely remove in mechanical or chemical filters. The proximity to the city of Løgstør places strict requirements on odorant emissions. The environmental authorities require a maximum of 10 LE at the facility and 5 LE at the neighboring boundaries and they conduct annual inspections.

FFV collects wastewater in Fåborg Municipality and treats it in central treatment plants. Over time, several smaller plants have been closed and now use long pipelines with pumping stations to bring the wastewater to treatment. This has led to the formation of harmful hydrogen sulphide in the wiring. There have long been attempts to solve the problem with various chemical methods or carbon filters. It’s been costly, but hasn’t had much of an impact. A particular problem is the large fluctuations in hydrogen sulfide formation called “peaks”, as high concentrations destroy odor filters and need to be smoothed out for effective cleaning. This requires effective mitigation and management of the plant’s biological processes.
