“True recycling requires processing at a level where theoutput substitutes virgin materials.Consequently this leads to avoided production and a profoundsaving of resources.”

Sammenligning af Road+ vs. SBS i forholdet 2,5:1Dokumenteret bedre performance når det drejer sig om:
SporkørselRevnerStøjdæmpningHøje såvel som lave temperaturerHøje såvel som lave belastninger

Miljøet - Udvaskning
Mindre udvaskning af organiske materialer

Miljøet - Emissioner
Emissioner er målt både ved blanding og udlægningIngen konstatering af N-nitrosaminesMindre emissioner af VOC’er og SVOC’er sammenlignet med konventionel polymer modificeretasfalt

Life Cycle Assessment
Recycling versus Co-incineration and Civil Engineering Applications
Page 11
What is a LCA-study?Evaluates and measures all known environmental impacts of a specific choice
….. of all steps in the complete life cycle of a particular product

Waste Hierarchy - TyresBest solutionDoes the waste hierarchyadopted by the EU standfor a detailedLCA-analysiswithin thetopic ofscraptyres?
Reduction- Traffic policyRetreading- UneconomicMaterial recovery- Genan conceptIncineration- Cement kilnsLandfill- Now banned in the EU
Worst solution

Results – Comparison with Co-incinerationGWP Base case1.1 ton/ton
GWP Waste subst.Acidification
2.6 ton/ton5.3 kg/ton
5 other categories Sign. positive2 other categories InsignificantIn the EU 1,098,000 tons scrap tyres are yearly incineratedThe potential CO2 savings are therefore in the area of 2.9 Mton
Comparison with civil engineering applicationsGWP savings approx. 1.8 tons CO2/ton scrap tyre input
Page 20
Overall conclusion
Civil Engineering applications are filling operations with no environmental benefitsCo-incineration in cement kilns is better than civil engineering and landfills
Recycling is, however, far more beneficial than co-incineration with robust and clearbenefits in 7 out of 9 environmental indicators2 indicators not statistically significant
