Introduction
» Ecolizer» Sheets with eco-indicators (EI)
» Measure for environmental impact» Expressed in mPt/unit (kg, m, m², tonkm,
etc)» Higher EI higher environmental impact
» Basis = LCA» Integral environmental impact» Life cycle perspective» LCI data

Method for calculation of eco-indicators
» Ecolizer 1.0» Eco-Indicator 99 method

Method for calculation of eco-indicators
» ReCiPe» Developed by Pré Consultants and CML (2009)» Combination of EI-99 and CML 2001 method» 3 steps:
» Environmental impact categories (midpoint)» E.g. Climate change, acidification
» Environmental damage categories (endpoint)» E.g. Damage to human health
» One environmental indicator: eco-indicator

Method for calculation of eco-indicators
» ReCiPe – environmental impact categories (midpoint)» Climate change» Ozone layer depletion» Acidification» Eutrophication (freshwater)» Human toxicity» Photochemical oxidant formation» Particulate matter formation» Ecotoxicity (terrestrial, freshwater, marine)» Ionizing radiation» Land use (agricultural, urban)» Depletion of resources (metals, fossil)

Method for calculation of eco-indicators
» ReCiPe – environmental damage categories (endpoint)» Damage to human health» Damage to ecosystems» Depletion of resources

Weighting factor (Hierarcist/Average)
Human health 400
Ecosystems 400
Resources 200

Comparison EI-99 and ReCiPe
» Difference between eco-indicator score according to EI-99 and ReCiPe method» Relative difference is not always consistent» Order of ranking and ratio remain more or less the
samen when comparing different materials/processes» Due to higher characterisation factors for a.o. DALY
versus CO2-equivalents

Points of attentionEnd of Life
» Per material sheet:» Recycling
» Impact of recycling process» Credits of avoided material production» Total
» Waste scenario EU» 80% disposal – 20% incineration
![Page 19: Workshop Ecolizer The methodology behind the Ecolizer 2.0](https://reader035.vdocument.in/reader035/viewer/2022062304/568134c9550346895d9bf132/html5/thumbnails/19.jpg)

Points of attentionEoL - incineration
» Only combustible flows go to incineration: no indicator for incineration of ferro, non ferro and inert materials
» Own calculations
» Emissions and avoided emissions to air, auxiliary materials taken into account
» Type of energy: electricity

Points of attentionRecycling
» 2 approaches:» “recycled content approach”
» Take into account the effective input of recycled material
» Use indicator for production of recycled material» NO recycling at end of life
» “end of life recycling approach”» Take into account the recycling scenario at end of life
» Use indicator for recycling process» NO input of recycled material
