have taken place in the area. Calculations and underlying considerations arediscussed in Appendix C.4.2.3 Landfill requirementFirst, landfill requirement is stated in absolute figures in tonnes. In the EDIPthere are four different categories of waste to landfill, normalised in relation tototal waste quantities for each of the four waste categories. For the indicatorcalculations it has been decided to establish a collective landfill factor for allfractions as a whole. The normalisation reference for landfilling is set at totallandfill requirement in Denmark in 1999.It may seem unnecessary to state landfill requirement as an independentparameter, as total quantities landfilled already appear from waste statistics.However, another entity is calculated here, since landfill requirement iscalculated in a life-cycle perspective. This means that, for example, landfillingof waste from extraction of raw materials is also included in landfillrequirement.A drawback of this indicator, however, is that landfilling of 1 kg is calculatedwith the same value whether the material landfilled is lead or glass. As long asin the LCA-context no weighting factor (based on impact factors) has beendeveloped that can be used to state the degree of problems relating tolandfilling of the different materials, it is beyond the scope of this trial to makea weighting. The EDIP project’s division into four categories cannot solve thisproblem either, so we have chosen to just calculate one overall value forlandfilling.4.3 Calculation in practiceEnvironmental impacts and resource loss upon landfilling and alternativetreatment options are calculated on the basis of EDIP data using a databaseprogramme that can calculate and manage the many intermediate results. Forthis purpose a programme has been used that has been developed by I/SØkoAnalyse in connection with the project ”Environmental impacts in thefamily” /14/.The calculation is carried out so that the different contributions to allparameters for environmental impact and resource use can be traced back tothe different processes. In Appendix D (not translated) tables are presented ofunit processes and waste quantities included in the calculations. Other tablesshow characterised and normalised values (see Glossary) for the threeindicators, distributed on the three material fractions, both for kilos of wasteand for total waste quantities.After an assessment of data quality, an aggregation has been made of theselected factors stated in Table 4.3. This makes it possible to survey whethersignificant contributions are missing. Once the assessment has been made, it ispossible to use the aggregated data for calculating resource, energy and thelandfill factors for the different materials to be multiplied by the relevant wastequantities.For the different forms of presentation of the results – including the twobasically different models, a further calculation has been made of thecalculated factors and amounts in a spreadsheet. Appendix D (not translated)36
presents data used and results, and it is also possible to find results brokendown into energy resources and other resources, as well as renewable andnon-renewable sources of energy.37
