Biobased Asphalt. The Path to a Greener Road Construction Industry

The CHAPLIN (Collaboration in aspHalt Applications with LigniN) program

• a meeting of 22 organizations comprising the entire road construction value-chain 
• works together to stimulate the development and commercialization of lignin-containing asphalt

What is lignin? 

• organic polymers that form key structural materials in plants and some algae 
• released during of paper production
• a good substitute for fossil bitumen, a non-sustainable petroleum product

How does it work?

Adding lignin to asphalt can make it 50% greener and reduce the temperature of  production and application by 86 °F. Lingin saves around 20% CO₂ and 50% of fossil fuels.
