Pienten maaseutukuntien metaanipotentiaalia tutkittiin tapauskohtaisesti Etel\u00e4-Pohjanmaalla sijaitsevassa Soinin kunnassa.\r\nSoinin biokaasun tuotannon mahdollisuudet selvitettiin kunnallisen j\u00e4teveden, erillisker\u00e4tyn bioj\u00e4tteen, maatalouden lannan ja nurmipotentiaalin materiaalivirtojen avulla k\u00e4ytt\u00e4en apuna vuosien 2011 ja 2012 tietoja.

Yhteishajotus parantaa kaasuntuottoa tutkimuksen mukaan hieman yli 2 %.\r\nSuomessa oli Soinin kaltaisia 2 000\u20133 000 asukkaan kuntia 43 vuoden 2011 lopulla. Mik\u00e4li oletetaan kaikkien kyseisten kuntien metaanipotentiaaliksi 10\u201320 GWh/v, voisi teoreetti-nen metaanipotentiaali olla kunnissa yhteens\u00e4 430\u2013860 GWh/v.

Especially manures are formed signifi-cantly in rural areas, but in small rural communes other organic waste streams can be rela-tively small. Methane potential in small rural communes was studied by using as an exam-ple Soini commune in Southern Ostrobothnia.\r\nPossibilities to produce biogas in Soini was studied by using material streams of municipal sewage sludge, separately collected biowaste, manure and energy crop potential from fallow fields from year 2011 and 2012. Methane potential from sewage sludge, cow manure and separately collected biowaste was studied. Methane potential of an example farm was studied from two mixtures (manure and sewage sludge as well as manure and separately collected biowaste) by using information for material ratios from year 2011 and 2012. Energy potential of different organic wastes and energy crops was ca. from 14.1 to 17.5 GWh/a in Soini which correspond as a net energy ca. from 43 to 53 % total electricity con-sumption of Soini in 2011. On the other hand the net methane potential corresponds ca. from 650 to 800 passenger cars fuel consumption or ca. from 450 to 550 detached houses heat energy demand annually. The example farm studied in this work could produce net energy 290 MWh/a if separately collected biowaste and municipal sewage sludge from Soini is used as raw material with manure. The farm could be self-sufficient with heat, electricity and fuel. Co-digestion gave little bit over 2 % better gas yield in this work corresponding to mono-digestion.\r\nThere were 43 communes in Finland, similar to Soini (2 000\u20133 000 inhabitants) in 2011. If assumed that these communes have same methane potential than Soini (from 10 to 20 GWh/a), could total theoretical methane potential be from 430 to 860 GWh/a. Waste streams can be utilized in small rural communes by using co-digestion with what which can improve biogas plants profitability according to studies. Biogas plants could be centralized plants which utilize manure and grass from many farms. Producing biogas in countryside with local resources could improve rural areas energy care certainty and employ-ment views with energy entrepreneurship. This kind of local energy production could confirm sustainable, eco-friendly and decentralized energy production and support renewable energy goals.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Kari Laasasenaho (kavijula) on 2012-12-14 13:42:22.386985.
