International Biochar Initiative Educational Webinar Series:

Recording: Biochar Use in Asphalt

Originally Aired: May 13, 2020 | 9:00 AM - 10:30 AM ET


Tens of thousands of kilometers of roads are built or rebuilt around the planet every year. For the past six years, road building company CarbonCor, has been piloting the use of different types of biochar in roads built in Malaysia, Thailand and most recently in Australia. They have developed road building materials that can sink up to 30 tons of biochar into 1 kilometer of road. At these rates, asphalt could potentially be a larger market for biochar than soils!

Beyond safely storing carbon for the foreseeable future, roads built using biochar are stronger, cheaper and can be built faster. This webinar will outline the environmental and economic benefits of using biochar inn CarbonCor’s environmentally friendly cold asphalt premix. CarbonCor’s Andre van Zyl has been building roads for decades; he will discuss the use of biochar to stabilize soils for roads as well as in the asphalt itself

Upon completion of this form and successful payment processing, you will receive a link to view the May 13, 2020 Biochar Use in Asphalt webinar and slides.


Andre Van Zyl Presenter

Andre Van Zyl graduated in 1986 as a Chemical Engineer from the Vaal University of Technology in South Africa. He has substantial experience in process plant design and implementation for the steel, water treatment, mineral processing and mining industry in Africa, Asia and South America. For the past 15 years he has focused substantially and has acquired specialized knowledge and skills in road surfacing technology especially in the development and manufacturing and installation of environmentally friendly emulsified cold road premix material for new urban and remote infrastructure development areas. During the last 4 years, he has been instrumental in the further development and re-design of the Carboncor Technology to suite specific climatic, geotechnical and soil conditions as viable and cost-effective road products in the ASIA region.

Kathleen Draper Moderator

Kathleen is a member of the IBI Board and Chair of IBI's Information Hub. She is also the US Director of the Ithaka Institute for Carbon Intelligence. The Institute is an open source network focusing on beneficial carbon sequestration strategies which simultaneously provide economic development opportunities both in the developed and developing world. She is an editor and writer for The Biochar Journal, sponsored by the Ithaka Institute. Kathleen also works with various different universities and individuals on projects that are investigating the use of biochar in cement and other building and packaging products to develop products with lower embodied carbon which can be made from locally available organic waste. She has written extensively about various topics related to biochar and is a co-author of the book "Terra Preta: How the World's Most Fertile Soil Can Help Reverse Climate Change and Reduce World Hunger" and “BURN: Using Fire to Cool the Earth”.
