Tiivistelmä
Increasing municipal solid waste (MSW) poses a significant environmental challenge. Globally, 2.24 billion tons of MSW are generated annually, leading to an average of 0.79 kilograms per person per day. Biogas plants offer a promising solution, generating renewable energy while producing digestate - a valuable fertilizer. However, efficient digestate handling, particularly for transportation and application, remains crucial.
The current thesis deals with a planned biogas project in Norway, called Rå Biopark, delving into strategies aimed at enhancing digestate treatment. Leveraging mass and energy balances, the study offers a comprehensive picture of material flow and energy consumption throughout the process. This investigation yielded significant results, including the production of 8,820 tons/year of biochar, 1,350 tons/year of fertilizer pellets, and 1,344 tons/year of ammonium crystals.
Furthermore, the thesis explores alternative digestate treatment methods, analyzing their operational efficiencies and potential for producing desired end-products. Excel templates were developed to facilitate future modifications based on acquired data. To conclude, this research aims to advance sustainable digestate management within Rå Biopark. Further research into the of digestate treatment technologies and the refinement of modeling techniques holds promise for continued advancements in sustainable waste management.
