“…This value is within the variations found in the literature: between 250 kWh/pig/year of which 15 kWh is heating (Denmark) and 1557 kWh/pig/year in the United Kingdom, of which 155 kWh is heating [23].…”

“…The number was verified by a review of figures in the literature. A literature review on the direct energy use on different types of farms found that annual energy use for cattle farms varied between 160 kWh/ dairy cow (New Zealand) and 2900 kWh/dairy cow (Switzerland) [23]. The heat demand on the Norwegian cattle farm seems to be in the upper area of the range found in the literature, which seems reasonable, since heat consumption in anaerobic digestion plants is high in the Norwegian climate [20], and energy efficiency studies on other farms in Norway seem to be within the same range [24,25].…”

Optimising Anaerobic Digestion of Manure Resources at a Regional Level

An optimisation model was developed to give decision support on methods of managing manure resources within a region to reduce greenhouse gases and at the same time obtain economic profitability for the farmer. The model was tested by performing a case study on 50 farms in one region in Norway. Based on input data on the number of cattle and pigs on each farm, and the transport distance between each farm and the nearest centralised biogas plant, the model calculates the economic profit of the farmer and the greenhouse gas emissions for three manure management alternatives: (1) no biogas production; (2) farm scale biogas production; and (3) centralised biogas production. The model could minimise the greenhouse gas emissions, maximise the profit for the farmers or a combination of the two. Results from the case study showed that both options for anaerobic digestion (farm scale and centralised biogas production) are beneficial in terms of the reduction of greenhouse gases and can be profitable for the farmers. The case study has validated the functionality and usefulness of the model. Some improvements are suggested for further development and use.

“…According to the University of Minnesota Center for Farm Financial Management, direct electrical and fuel usage accounts for 2%–5% of the costs associated with pig production . The potential economic and environmental impacts of energy use during agricultural and livestock production have recently become a concern . Accordingly, regulations requiring reduced agricultural greenhouse gas emissions and increased energy prices are forcing animal producers to find alternative sources of energy.…”

Increased energy price and CO2 emissions through burning fossil fuel for heating nursery pig houses in winter are major problems. This study was conducted to evaluate the combined effects of an active solar and geothermal heating system (CSGHP) on electricity use, cost, and CO2 and noxious gas emissions from pig houses during heating in winter at the experimental farm of Sunchon National University, Korea. The electricity use, inside room temperature, humidity, and noxious gas emissions were measured and CO2 emissions and costs were calculated based on the difference in electricity used by control (conventional electric heating system) and CSGHP supported pig houses. A significant increase in internal room temperature was found in the CSGHP system relative to the control house (P < 0.05). Electricity use, CO2 emissions and costs were reduced substantially in the CSGHP system compared with the control house. Moreover, noxious gas emissions were reduced significantly in the CSGHP system relative to the control (P < 0.05). Overall, the results of this study indicated that the CSGHP system has the potential to reduce electricity use, overall cost and CO2 and noxious gas emissions. Therefore, the CSGHP system has the potential for use as an environmentally friendly renewable energy source for animal houses. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 1156–1165, 2016
