The objectives of this study were to evaluate the current solid waste management at the University of Jyv\u00e4skyl\u00e4, to carry out the feasibility study for the biogas plant and to estimate the energy balance, greenhouse gas emissions and possible emission savings. Based on the chemical composition and methane potential of these organic wastes, biogas plant was designed with different Scenarios. In first Scenario, the only feedstock is biowaste produced in the University of Jyv\u00e4skyl\u00e4 and Kortepohja Student Village. In second Scenario, the garden waste from the University premises is added. Third Scenario utilizes all biodegradable waste streams generated at the University of Jyv\u00e4skyl\u00e4 and biowaste from Kortepohja Student Village.\n\nAt the moment the biowaste generated at the University is transported to Mustankorkea landfill to be composted. Most of the biowaste generated at the University is food waste from the Sonaatti Ltd, which owns the restaurants and cafeterias located in the University premises. The total amount of organic wastes in 2012 generated at the University of Jyv\u00e4skyl\u00e4 was 491 tons per year. Among the waste streams suitable for anaerobic digestion, the paper waste has the biggest proportion \u2013 approximately 55 %, followed by cardboard and biowaste both with fraction of 20 % and garden waste with 5 %.\n\nScenario 3 would be the most feasible option if considering the energy production as the Scenario produced by far the most amount of biogas (211 173 m3/year). As the Scenario 1 utilizes only biowaste with the highest methane potential, Scenario 1 has the highest biogas production per reactor size and per feedstock amount but volumetric amount (in Run 1 15 765 m3/year and 35 691 m3/year in Run 2) is much lower than in Scenario 3. As the biowaste is the only waste stream that requires pasteurization, the energy efficiency of the option is slightly lower than with those options that add other waste streams. All studied Scenarios have the potential to give higher greenhouse gas emission savings when biogas replaces fossil energy than the emissions the plant operations and transportations cause.\n\nSince the University of Jyv\u00e4skyl\u00e4 is a large institute with enormous energy consumption compared to moderate waste production, the energy produced by the biogas plant cannot reach high levels of replacement. The highest replacement level (1.3 %) could be reached with Scenario 3 in the University level while Scenarios 1 and 2 could reach from 0.07 % to 0.2 %.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Anna-Maria Rauhala (anvirauh) on 2013-09-12 13:15:31.022350.
