In connection with the research project RESTORE, we conducted an analysis of all organic waste – or rather resources – at Mære Agricultural School. The goal was to get a better overview of the resources we have that can be used in compost, biochar plants or biogas plants. In RESTORE we look at how we can utilize biochar, biogas, compost as technologies for more sustainable management. We also look at how we can use biochar to reduce emissions of greenhouse gases or nutrients.
From the milk barn, suckler cow barn, pig house and sheep barn, approximately 8,500 tons of manure are produced annually. These are resources that can be used in a biogas plant where we extract the biogas before it is spread on our land. From the stable and the calf department, approximately 350 m3 of horse manure and 80 m3 of straw manure are produced. These are resources that can be included in a compost plant, but can also be considered for use in a biochar plant. In the greenhouse, tomato production contributes leaves, stalks and some tomatoes, while summer and Christmas flower production has some waste, a total of approximately 150 m3. Tomato production is emptied approximately once a year and this contributes approximately 40 m3 of tomato plant residues. Residues from the greenhouse can be included in our compost, but can also be considered for use in biochar production and biogas plants.
RESTORE is a collaboration between NIBIO, NGI, SINTEF and Mære Agricultural School funded by the Research Council of Norway.
