The already existing seasonal collection of bio-waste from
tourist areas in Ylläs and interviews of local restaurants, hotels and
grocery stores as well as tourists indicate that there is willingness
to extend the source separation of wastes. As well, studies on wearing
of Northern tourist areas point out the vital need to regenerate
eroded areas. As both the amounts of bio-waste and the severity
of erosion caused by tourism are critical problems in the tourist
areas of Lapland, the zero waste perspective of bio-waste digestion
and local use of digestate for revegetation purposes need to be
carefully considered. The calculations presented in this paper are
estimates;therefore, further studies will be needed before the realization
of this Scenario is considered. Exact waste amounts, logistic
expenses, expected and avoided costs would need to be carefully
calculated and weighed, to ensure economic and environmental
sustainability (Sonesson et al., 2000). Establishment of a biogas
facility in Kolari will require also safe storage for digestate, as it cannot
be spread when the ground is frozen. A key concern is to ensure
the safety of digestate use. The physical, biological and chemical
characteristics (leaching nutrients, contaminants) of digestate,
