ASSESSMENT OF ORGANIC WASTE MANAGEMENT METHODS THROUGH ENERGY BALANCE

摘要: In Italy, the Organic Fraction of Municipal Solid W aste (OFMSW) is nowadays landfilled or processed through aerobic composting. The Italian towns curre ntly support a high cost for OFMSW disposal and cause environmental impact, because long distance s travelled from to few available landfills fewer treatment places, as well used waste m anagement methods. An interesting option Anaerobic Digestion (AD), producing biogas “digestate”. this survey theoretical plant was placed near town Sicily Region (Italy), centra lised with reference area considered pro ducing OFMSW. distances every year transport nine nearest composting one were ca lculated using QGIS software. Therefore, energy balance computed each four scenarios. Within implementation Integrate d Waste Management (ISWM) method, AD resulted in an much higher than that aerobi c fact, differently composting, A D can significantly contribute recovery, while retaining nutrients digestate produced nd reducing Greenhouse Gas (GHG) emissions. use rational network collection transportation results relevant, terms increa sed balance, only case refore, if would be implemented management by means plants, them including some towns, e.g . survey, it could highly red uce impact disposal.
