Levenscyclusanalyse - LCA
Life Cycle Assesment (LCA) of levenscyclusanalyse is een internationaal gestandaardiseerde methode die wordt toegepast om de milieu-impact van een product en/of dienst te berekenen door het product te bekijken over zijn gehele levenscyclus (van de ‘wieg tot aan het graf’).
De verschillende stappen van een levenscyclus van een product
Deze wetenschappelijk onderbouwde methode is de beste manier om zeer specifieke en uitgebreide informatie rond de milieu-impact van een product/dienst te verkrijgen.
Het bekomen van deze bron aan informatie en de resultaten van de analyse houdt veel werk in, en dit tegen een hoge prijs.
Veel bedrijven, en zeker ontwerpers, worden hierdoor afgeschrikt, maar dit verminderd het belang van een degelijke LCA studie zeker niet.
Levenscyclusanalyses worden meestal uitgevoerd door specifieke onderzoeksbureaus die hierin al enige expertise hebben opgebouwd (bvb. Vito), maar de resultaten, die moeten door de ontwerper juist geïnterpreteerd en toegepast worden.
Als ontwerper is het dus belangrijk om het basisidee van een LCA, nl. het rekening houden met de milieu-impact de aanpak in grote lijnen en de weergave van de resultaten te begrijpen en te kennen. Deze laatste twee punten worden achtereenvolgens aangehaald.
Globale aanpak LCA
De standaard methode voor de uitvoering van een levenscyclusanalyse is vastgelegd door ISO, de International Organisation for Standardisation, in de ISO 14040 serie (deze 14000 serie bevat standaarden voor milieumanagement systemen). In deze gestandaardiseerde methode wordt een LCA studie ingedeeld in 4 fasen:
1 Definitie van doel en reikwijdte (link naar meer uitleg op aparte pagina?!?)
2 Analyse van de levenscyclusinventaris
- Materialen
- Productie
- Gebruik
- Afdanking
3 Berekening van de impact over de hele levenscyclus
4 Interpretatie van impact van de levenscyclus
Hier kan je een overzicht bekijken van de verschillende stappen die binnen Vito, het Vlaams Instituut voor Technologisch Onderzoek, worden toegepast voor het gebruik van deze methode.
Enkele voorbeelden van ‘Life Cycle Impacts’
Er bestaan ook vereenvoudigde versies van LCA’s voor ontwerpers, zoals de streamlined LCA, waarbij de accuraatheid van de resultaten iets daalt, maar waarvoor minder tijd en geld nodig is.

Hello,
This is nice. But I think in the way you define the topic, it is good but not in the way it should be..
