Plant-Powered
Construction Innovation

Our economical soy-based products make infrastructure and energy systems more resource-efficient. We help refineries unlock greater fuel and lubricant yield while converting residues into durable paving asphalt. We empower owners and transportation agencies to use more recycled asphalt materials while extending pavement life. We save homeowners money by helping their roofs last longer. Our mission: affordable, longer-lasting roads and roofs, reduced waste, and a cleaner path forward.

Our Story

At SoyLei Innovations, we transform soybean oil into low-cost, high-performance solutions that help refineries and owners of pavements and roofs save money, improve efficiency, and reduce waste. Whether it's getting that last drop of fuel out of every barrel of oil, that last mile out of an aging pavement, or that last year from a roof, SoyLei uses our farmers' bounty to keep our infrastructure looking great with less waste.

Our journey began in 2008, when a supply crisis challenged the asphalt industry to find new answers. Our founders invented a range of soy-based polymers and additives that offer an unmatched blend of cost and performance. Just ask our customers!

We won’t stop at asphalt. From concrete preservation to emulsions and specialty applications, our products are engineered for both today’s infrastructure needs and tomorrow’s sustainability challenges. At SoyLei, we’re not just improving materials—we’re shaping a cleaner, more resilient future.
