Evaluation of a Model Used for Environmental Assessments of Waste Management Systems
(2019) FMIM01 20191Environmental and Energy Systems Studies
- Abstract (Swedish)
- I rapporten utvärderas the Waste Management Planning System (WAMPS), som är ett förenklat LCA-baserat verktyg för att jämföra avfallsscenarion utifrån miljömässiga aspekter. Syftet med studien var att hitta bristfälliga områden i modellen som behöver förbättras/uppdateras. Utvärderingen genomfördes genom att jämföra modellens struktur med liknande modeller samt genom att jämföra de resultat som beräknas i modellen med motsvarande värden från litteratur. Utvärderingen av beräkningarna inkluderade materialåtervinning av aluminium, stål, plast, glas, papper samt förbränning och kompostering. Klimatpåverkan var den enda påverkanskategori som undersöktes.

Utvärderingen genomfördes genom att jämföra modellens struktur med liknande modeller samt genom att jämföra de resultat som beräknas i modellen med motsvarande värden från litteratur. Utvärderingen av beräkningarna inkluderade materialåtervinning av aluminium, stål, plast, glas, papper samt förbränning och kompostering. Klimatpåverkan var den enda påverkanskategori som undersöktes.
Jämförelserna visade att WAMPS stämmer överens med litteratur i de flesta avseenden. Utvärderingen av strukturen visade att de huvudsakliga avvikelserna i WAMPS är att det saknas en utförlig dokumentation över de beräkningar som görs i modellen, att det i beräkningarna av energi saknas en valmöjlighet för användaren att välja olika typ av energi som används i förgrundssystemet respektive vilken energi som ersätts i bakgrundssystemet, samt att det i grundversionen av WAMPS endast tas hänsyn till det rejekt som uppkommer vid förbehandling av materialåtervinning. Det senare går dock att ändra för användare med admin-tillgång.
Utvärderingen av beräkningarna påvisade avvikelser mellan WAMPS och värden från litteratur gällande materialåtervinning av stål, glas och kompostering. Jämförelsen visade också att fokus bör ligga på att kvalitetssäkra beräkningarna i de fraktioner som behandlar stora mängder avfall, då även små avvikelser i dessa kan ge stora effekter på resultatet. Den utförda jämförelsen innehåller dock flera osäkerheter. Dels jämfördes europeiska data med värden från WAMPS som är utvecklad i Sverige, och endast några aspekter av WAMPS utvärderades.
På grund av osäkerheterna i studien bör resultatet verifieras med en mer noggrann studie och på grund av den begränsade omfattningen av studien bör även en mer omfattande studie göras där fler fraktioner inkluderas, andra aspekter studeras och fler litteraturkällor används. (Less) - Abstract
- This report evaluates the model Waste Management Planning System (WAMPS), which is an LCA-based tool used to compare different waste management scenarios from an environmental perspective. The aim of the study was to find deficient areas in the model that needed to be updated or improved. The evaluation was conducted by comparing the structure of the model to the structure of similar models and by comparing the results calculated in WAMPS to corresponding values found in literature. The evaluation of the calculations considered the treatment systems: material recycling of aluminium, steel, plastic, glass, paper, incineration and composting. The only impact category that was assessed was Global Warming Potential.

The evaluation of the calculations considered the treatment systems: material recycling of aluminium, steel, plastic, glass, paper, incineration and composting. The only impact category that was assessed was Global Warming Potential.
The comparisons revealed that WAMPS agrees with literature on most aspects. The evaluation of the structure showed that the main deviations in WAMPS are that there is a lack of a detailed documentation of the calculations in the model, that it is not possible for the user to choose different types of energy that is used in the foreground system as opposed to the energy that is substituted in the background system, and that the model only accounts for the reject formed in the pre-treatment of material recycling. The latter aspect can however be altered by a user with admin access.
The evaluation of the calculations revealed deviations between WAMPS and literature regarding material recycling of steel, glass and composting. The comparison also showed that the calculations of the fractions that treated most of the waste should be quality assured, since a small deviation in these can render large impacts on the result. The conducted comparison however contains several uncertainties. European data was compared to values from WAMPS which is developed in Sweden, and only some aspects of WAMPS were considered for evaluation.
Due to the uncertainties in the result, the deviations found in this report should be further verified by a more detailed study. This study was also limited in its extensiveness which is why a more comprehensive study should be conducted where more fractions are included, other aspects studied, and additional literature sources are used.
