20.500.12556/DKUM-87085 Food Waste to Energy through Innovative Coupling of CHP and Heat Pump This paper presents the conceptual design of a technological solution for the efficient conversion of food waste into heat and power. The distribution and composition of food loss and waste at different stages of the food supply chain in Slovenia and their potential for biogas production were determined. It was found that more than 50% of food waste comes from households. Therefore, a small plant was designed to convert food waste into biogas, which was innovatively coupled with a combined heat and power (CHP) unit and a heat pump. This doubles the amount of heat generated compared to conventional cogeneration. Based on the capacity of a micro commercial CHP unit, 3330 households (about 8000 residents) would supply food waste. The heat generated could replace 5% of the natural gas used for domestic water heating. The payback period would be 7.2 years at a heat price of about 80 EUR/MWh, however, for municipalities with more than 40,000 inhabitants the payback period would be reduced to less than 3 years. The cost price of the heat generated by this system would be about 25 EUR/MWh, taking into account the government subsidy for the operation of the CHP unit. food waste to energy biogas combined heat and power CHP heat pump efficiency conceptual design preliminary economic assessment sensitivity analysis odpadna hrana bioplin toplotne črpalke energija true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/energies Članek v reviji 2024-02-16 13:15:26 2024-02-16 13:27:17 2024-04-18 14:44:25 0000-00-00 00:00:00 2023 0 0 Str. 1-18 Št. 8, št. članka 3344 Letn. 16 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-03-01 2023-04-07 2023-04-10 620.92/.98 148403203 10.3390/en16083344 1996-1073 Drofenik-2023-Food_Waste_to_Energy_through_Inn.pdf Drofenik-2023-Food_Waste_to_Energy_through_Inn.pdf 1 56666CBFE08793D17FA93DBCE4311644 78983e19871d57fa56654488ef8805be905a3d2edcfc9a9eeb070777ee97578e 586f31bd-ccc6-11ee-b5a0-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=176214 https://www.mdpi.com/1996-1073/16/8/3344 0 9f373d5f-ccc6-11ee-b5a0-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=176215 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
