In the United States (US), Verde Resources, Inc., a leader in sustainable, next-generation infrastructure materials, has disclosed groundbreaking preliminary findings from the National Center for Asphalt Technology (NCAT), revealing the transformative impact of its "TerraZyme" technology in road construction.
The Life Cycle Assessment (LCA) of Verde’s S-11 cross-section at the NCAT Test Track demonstrates significant advancements.
Compared to a conventional method also installed on the track, TerraZyme reduced overall carbon emissions by 46 percent, cut Portland cement use by 60 percent, and eliminated hydrated lime.
By utilizing in-situ soil, it further minimized reliance on externally sourced materials, reducing the logistics footprint.
Eight months of comparative data confirm S-11’s superior performance, with minimal rutting, no cracking, and an exceptionally low International Roughness Index (IRI).
These achievements were realized during the subgrade and base layer construction in August 2024.
The numbers speak for themselves, and we couldn’t be more thrilled. These results confirm TerraZyme’s environmental and economic benefits, paving the way for broader adoption in road construction across the United States and globally. By demonstrating significant carbon reductions and enhanced performance, we’re driving industry acceptance and investment in sustainable infrastructure, said Eric Bava, COO of Verde.
Register for carbon avoidance credits
The data from NCAT will be submitted to Climate Action Reserve as part of the ongoing application to register this project and generate carbon avoidance credits, further validating the concept.
This enzyme technology has been incredibly impressive, not only in reducing carbon-intensive materials but also in overall emissions reduction and performance. We will continue monitoring and collecting data, but TerraZyme is shaping up to be a game-changer in the road construction industry, said Nathan Moore, NCAT’s lead for the test track program.
Verde remains committed to driving innovation in Net Zero road construction by collaborating with strategic partners to commercialize common-sense, sustainable infrastructure solutions.
The company will share further insights as additional data emerges.
