Ingevity’s Evotherm® P35 receives BASt approval in Germany

Key Terms

warm-mix asphalt technical

Warm-mix asphalt is a type of road paving material produced and placed at lower temperatures than traditional hot-mix asphalt by using additives, water, or modified processes that reduce the mix’s viscosity. For investors, it matters because lower production temperatures can cut fuel and equipment costs, reduce emissions and worker exposure, and allow longer paving seasons or faster project completion, all of which affect contractor margins, regulatory compliance, and demand for paving services.

hot-mix asphalt technical

Hot-mix asphalt is a road-building material made by heating and blending crushed rock with a liquid bitumen binder so it can be spread and compacted while warm, like pouring heated cake batter that sets as it cools. Investors care because its demand and price reflect construction activity, municipal road budgets and oil-linked input costs, so changes affect contractors, suppliers and infrastructure-related revenues and margins.

activated carbon technical

Activated carbon is a highly porous form of carbon that acts like a microscopic sponge, trapping impurities, odors and chemicals on its large surface area. Investors watch it because its demand and price reflect spending on water and air purification, industrial filters, medical treatments and environmental cleanup—areas that drive sales and margins for producers and indicate broader trends in regulation, public health and industrial activity.

bio-based materials technical

Materials made wholly or partly from renewable biological sources—such as plants, algae, microbes, or organic waste—instead of petroleum or other fossil fuels. Think of them like recipes that swap oil-derived ingredients for plant-based ones; they matter to investors because they can change production costs, regulatory risks, sales opportunities, and supply chains as markets and policies shift toward lower-carbon or sustainable products.
