Calculation of Damage Factors Investigation of related land-use (=default inventories on land-use) Impact factors on ‘eco-system’ by land-use due to waste landfill and resource extraction were developed. Calculation of 2 damage indicators per 1m 2 land-use by each activity Safeguard Subject: Biodiversity Damage Indicator: Increment of Extinction Risk of Vascular Plants By Lost Population Safeguard Subject: Primary Productivity Damage Indicator: Loss of Net Primary Production By land change and occupation

A Case Study Comparison of recycling/disposal systems of MSWI residues solidification of fly ashash treatment landfillextraction of aggregate production of cement ,0001,2001,4001,600 #3 CO 2 (kg) #2 # NPP damage (t) #3 #2 #1 Results for CO 2 and Land-Use is quite different for this case. Land-use aspects is worth to include in LCA for IWM Expanded Systems for Equal Functional Units Treatment of 1,000kg MSW residues Production of 476kg aggregates Production of 1,630kg cements System #1Landfill of MSWI residues System #2 Slag production by ash melting Landfill of fly ash after solidification System #3 Eco-cement (production of cement from MSWI residues)
