Biogasification harvests energy from recycled and treated food waste. Sorting food waste is key to Denmark’s goal of recycling 50% of household waste by 2022. This project, sponsored by Dansk Affaldsforening, researched practical and motivational factors influencing Danish sorting of household food waste through interviews with citizens and waste sector experts, waste treatment plant site visits, two surveys and a social media photo survey. Our recommendations for an effective campaign to sort waste include: give clear, simple information; show results to intrinsically motivate people; and focus on children to perpetuate the habit. These results yield valuable insights for Dansk Affaldsforening’s members for implementation of future food waste sorting campaigns
