Nut en noodzaak van Biobased bindmiddelen

voor Circulair Asfalt. P.A. Landa

Onderscheid in Twee hoofdstromen in BioBased asfalt.

• Verjongers van bitumen– LynPave oliën gemaakt van de vlasplant.

– Biologische reststromen uit de voeding en industrie

• Vervangers van bitumen– Bioharsen

– Lignine afkomstig van hout en 2de generatie bioraffinaderijen.

• Waarom ?:– Niet fossiel maar hernieuwbaar door aanplant en oogst

– Verhogen van de circulariteit in de asfaltketen

Lignine als vervanger voor bitumen

State of the Art

• Proof of principle

• Tot 50% vervanging

• Hoge potentie

• Typische geur

• Nog veel te doen !!

Noodzaak voor verjonging

• Asfalt wordt gemaakt met bitumen afkomstig van de fossiele grondstof Aardolie.

• Bitumen verouderd en het Asfalt wordt brosser en gaat scheuren en rafelen.

• Verouderd bitumen dient weer “flexibel” gemaakt te worden door het te verjongen. (rejuvenation)

• Dit gaat uitermate efficiënt met BioBased LynPaveolie. (veel minder nodig dan een minerale olie)

VoordelenLynPave

• Lagere temperatuur (95/125°C)

• Energie reductie (30-40%)

• CO2 reductie ( >> 40%)

– Lagere temperatuur

– BioBased vastlegging van CO2

– Betere functionele eigenschappen

• Langere levensduur

• Dunnere constructies
