This year’s NLA Annual Meeting will be held from June 9 - 11 at the beautiful Omni La Costa Resort & Spa in Carlsbad, California, a premier destination located just north of San Diego. Set on 400 acres, the recently renovated resort offers attendees championship golf courses, eight resort pools, a full-service spa, and more. Guests will be treated to various tours and receptions, on top of the interesting speakers and topics during the meeting. We look forward to seeing our members next week!

Critical minerals and rare earth elements are used in products such as batteries, semiconductors, electric vehicles, electronics, and telecommunications equipment. Lime supports the processing of these materials by helping control pH levels, removing impurities, neutralizing acids, and assisting with mineral separation and recovery processes. In fact, limestone is a critical mineral as well!

These applications help support efficient production and the development of high-purity materials needed for advanced manufacturing and modern infrastructure. As demand for domestic critical mineral production grows, lime continues to play an important role across the supply chain.

Lime-based materials such as limestone (CaCO3), quicklime (CaO), and dolomite (CaMg(CO3)2) are essential ingredients in glass manufacturing, helping improve the chemical durability and strength of products ranging from windows and fiberglass to food containers and smartphone screens. They also help lower melting temperatures during production, improve furnace efficiency, prevent crystallization, and increase resistance to weathering and corrosion for longer-lasting glass products.

Lime also contributes to the production of specialty glass used in fiber optic infrastructure, which increasingly supports high-speed data transmission as fiber networks continue replacing traditional copper systems.

Its role in stabilizing glass composition makes lime an important part of products used every day across homes, transportation, and technology.

Last week, National Lime Association Executive Director Bill Herz and General Counsel Bradford Frisby visited MLC’s Ste. Genevieve (pictured) and Bonne Terre facilities alongside U.S. EPA staff Haley Turner and Kevin McGinn to provide a firsthand look at lime manufacturing operations and discuss key issues facing the lime industry.

The visit highlighted the essential role lime plays across American industry, as well as the operational, regulatory, and environmental challenges impacting producers. Thank you to MLC and Jonathan Kennedy, pictured here alongside EPA staff, for hosting an informative and productive discussion.

NLA Communications Manager Colleen McNickle spent a day last week at the National Association of Manufacturers (NAM) Professionals Staff Workshop, where she heard from Melody Wilding, Margot Murphy from NAM, Joy Johnson from the Pennsylvania Manufacturers Association, Stacie Manger from the American Forest and Paper Association, Alex Dickinson from Beekeeper, Nick Pericle from Tenexity Inc., and Charles Crain and Stef Webb from the NAM.

The group learned about everything from manufacturing initiatives, how to push your career forward, how to leverage AI in the workplace, and industry activities on the Hill. Communications professionals had a breakout session focusing specifically on corporate communications and online audience engagement.

Thank you to all the speakers, as well as Amy Rawlings and Keith Smith at NAM and the entire NAM team, for such a productive and informative meeting.

Lime is used in road construction to improve the foundation, performance, and longevity of pavement systems.

It is commonly applied to stabilize soils beneath pavement, increasing the soil's strength and reducing moisture sensitivity. Lime can also be incorporated into asphalt mixtures, where it helps bond and prevent moisture-related damage.

When you are on the road during your summer vacation this year, say a quick thank you to Lime.

Whether you are using lime to balance soil pH in your garden or spending the day outdoors hiking and enjoying landscapes shaped by limestone, enjoy spring weekends alongside Lime.

That connection between healthy soils and natural landscapes is grounded in the same material role lime plays across environments. For example, many West Virginia soils require up to four tons to get the highly acidic (pH 5.5) soils back to neutral, a step for improving nutrient use efficiency from applied fertilizers. This becomes especially important as fertilizer prices continue to rise, making efficient nutrient uptake more valuable than ever. https://www.dtnpf.com/agriculture/web/ag/crops/article/2026/04/01/4-fertilizer-prices-rise-double-1

Researchers at Cornell University, led by Phillip Milner, are developing a new carbon capture system powered by sunlight, aiming to reduce the energy required for traditional technologies. At the same time, companies like Origen are rethinking industrial processes themselves and redesigning lime production to capture CO₂ at the source. Together, these innovations address emissions from essential materials like lime, cement, and steel, which will require both technologies and integrated solutions across the supply chain.

As demand for AI grows, so does the construction of massive new data centers around the world. Most conversations about their environmental impact focus on electricity use. But there is another huge component... the materials used to build them.

Lime plays an essential role in the data center supply chain. It is used in soil stabilization before construction, in cement and concrete production, in steelmaking to remove impurities, in aluminum refining, in copper extraction, and even in lithium battery production for backup power systems. It is also used for water treatment during operations. A single large data center campus can require tens of thousands of tons of lime across construction and operations.

As the world rapidly expands digital infrastructure, the role of foundational materials like lime becomes even more important.

NLA members, we will be talking about Lime and AI, as well as other similar topics, at our annual meeting in June! Get excited!
