Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Biogas treatment of animal manure is common in Denmark, but still very little developed in Norway. Due to relatively small herds, large distances and low energy prices, costs are a challenge when constructing biogas plants on farm level in Norway. Residues from food industry may be an option to increase the biogas output. In Tingvoll, ca 120 km southwest of Trondheim, a pilot biogas plant for treatment of animal manure will be built on an organic research farm during 2010. Locally available food waste includes residues from fish oil production. Wax, soap and bleaching earth is available. Wax may also be utilized to replace fossil oil in heating boilers, and may hence be less relevant for biogas purpose. On the other side, bleaching soil and soap may contain elements that are not feasible for the biogas process, or for the biogas residue as a soil conditioner. Hence, wax was selected as the first residue to test for its biogas potential.Contact to the Research Centre Foulum at Århus University, Denmark, was established during a study tour in October 2009. Dr. Alastair Ward and his staff at Foulum conducted a trial with fish wax and cattle manure during December and January 2009-2010. The work was paid by the fish oil producer, GC Rieber Oils, Kristiansund, Norway. Bioforsk Organic Food and Farming, Tingvoll is scientifically responsible for the pilot biogas plant at Tingvoll, and has been the active partner in the contact to Research Centre Foulum from the Norwegian side. Århus University is grateful to GC Rieber Oils for the research task, and the permission to publish this report in the university report series.

Biogas is of interest in organic farming to decrease the dependence of fossil fuels, reduce greenhouse gas emissions and improve the N utilisation of animal manure. Addition of substrates with high energy content increases the gas output. Fish fat from fish oil industry is an interesting option. Studies are needed to assess possible contaminations such as pesticide residues (DDT etc.). The pilot biogas plant at Tingvoll research farm will be the first to treat manure from certified organic farming in Norway, and will be utilised for testing, optimisation and demonstrations.

Regjeringen har satt som mål at 30 % av all husdyrgjødsel skal behandles i biogassanlegg innen 2020. Det betinger stor utbygging av anlegg, noe som krever helt andre rammevilkår enn hva tilfellet er i dag. Produksjon av biogass i landbruket må rett og slett bli lønnsomt for at gårdbrukere skal kunne investere i egne anlegg. Biogass blir produsert ved at organisk materiale, som husdyrgjødsel, matavfall og slam, blir behandlet i en lufttett tank. Biogassen kan utnyttes til produksjon av strøm og varme, eller den kan oppgraderes til biodrivstoff. Det finnes ca. 30 biogassanlegg i Norge. De fleste av disse er basert på slam, bare noen få har husdyrgjødsel som viktigste råstoff.

Chlorine - one of the most widespread elements on the Earth - is present in the environment as chloride ion or bound to organic substances. The main source of chloride ions is the oceans while organically bound chlorine (OCl) comes from various sources, including anthropogenic ones. Chlorinated organic compounds were long considered to be only industrial products; nevertheless, organochlorines occur plentifully in natural ecosystems. However, recent investigations in temperate and boreal forest ecosystems have shown them to be products of biodegradation of soil organic matter under participation of chlorine. It is important to understand both the inorganic and organic biogeochemical cycling of chlorine in order to understand processes in the forest ecosystem and dangers as a result of human activities, i.e. emission and deposition of anthropogenic chlorinated compounds as well as those from natural processes. The minireview presented below provides a survey of contemporary knowledge of the state of the art and a basis for investigations of formation and degradation of organochlorines and monitoring of chloride and organochlorines in forest ecosystems, which has not been carried out in the Czech Republic yet.
