Abstract
Increasing amounts of wastes, seasonal changes and tightened waste legislation and regulations in EU and Finland together with long distances cause challenges to waste management in Lapland. Anaerobic digestion (AD) process produces biogas with high methane content and is one potential waste-to-energy technology to produce heat and electricity in Combined Heat and Power (CHP) plant, reduce harmful landfill gases and requirement of external energy produced by fossil fuels. Local biogas production in anaerobic digestion processes also reduces the waste transportation expenses to landfills, which can be hundreds of kilometers away in Lapland. Efficient waste management and producing renewable energy improve the image of the area. In this study, the amount of wastes collected in Kolari and the Ylläs tourist center is analyzed and the biogas potential is estimated. Seasonal variations in waste amounts were significant and were found to correlate with the number of tourist visits.
