Abstract:
Improving bio-waste collection enhances production of biogas, soil products, and recycled fertilizers. This study aimed to refine sorting, reduce mixing with other waste, and improve bio-waste quality. Focused on a pilot apartment area in Finland, housing about 350 residents, campaigns promoted better sorting, distributing paper bio-waste bags. Studies analyzed mixed waste composition before and after the communication campaign. Additionally, the area's bio-waste and mixed waste quantities were tracked from 2020 to 2023. Results showed improvement: bio-waste in mixed household waste decreased from 35 Wt% in 2020 to 27% in 2021. Separately collected bio-waste notably increased by 47% per resident in 2021-2023 compared to baseline year of 2020. On average, 146 kg/person/year of mixed waste and 55 kg/person/year of bio-waste were produced annually. Despite progress, 14 tons of bio-waste yearly ended up in mixed waste, holding potential for 2,800 cubic meters of biogas. Continuous resident communication remains vital for sustained improvement.
