Manufacturing Concrete-grade Fly Ash from Landfilled/Impounded Sources
September 15, 1-2 pm Eastern
Presented by Kyle Flynn, Vice President of Business Development, Separation Technologies LLC, a Titan America business
Hosted by Lionel Lemay, PE, SE, LEED AP | ConcreteNexus
High quality concrete-grade fly ash is becoming more difficult to reliably source due to the retirement of coal fired electric generation units. Fly ash remains an important tool for concrete producers to meet demanding specifications while reducing mix cost and improving sustainability. This presentation describes how Separation Technologies LLC, a Titan America business, is investing in new processing capacity to manufacture concrete-grade fly ash using historic waste coal ash from landfills and impoundments as a feedstock.

THE FUTURE OF CONCRETE WEBINAR SERIES
Sponsored by Climate Earth and hosted by Lionel Lemay of ConcreteNexus, The Future of Concrete explores how the industry is rapidly evolving to meet new expectations for sustainability, performance, and transparency. Each monthly session features practical, real‑world conversations with producers, designers, owners, and policymakers who are shaping the next generation of low‑carbon, high‑performing concrete. From EPD‑driven specifications and responsible sourcing to LEED, Envision, and emerging policy trends, the series highlights what’s changing in the market—and what it means for competitive, resilient project delivery. Join us to stay ahead of the curve and understand where concrete is headed next.

CCMPA x Climate Earth: Canada’s Concrete Masonry EPD Update
September 9, 2026
2 PM Eastern | 11 am Pacific
Online
CCMPA and Climate Earth are coming together to help concrete masonry producers understand Canada’s evolving EPD landscape, including PCR rule changes, 2026 industry-average EPDs, low carbon project specification guidance, and future carbon reporting expectations.
Attendees will learn how to:
- Understand what PCR changes mean for concrete masonry products
- Review 2026 industry average EPDs for concrete masonry in Canada
- Be introduced to CCMPA's Guide to Low Carbon Project Specifications
Communicating Sustainability Without Losing the Room — Messaging for Producers
October 14, 2026
2 PM Eastern | 11 am Pacific
Online
Join host Lionel Lemay, Founder and CEO of ConcreteNexus along with an expert panel as they explore how to explain low-carbon concrete to architects, engineers and contractors. They will discuss how to address the common myths (“concrete isn’t sustainable,” “it cracks,” “too expensive”) along with storylines that win over skeptical stakeholders.
Concrete Sustainability Excellence
November 11, 2026
2 PM Eastern | 11 am Pacific
Online
Join host Lionel Lemay, Founder and CEO of ConcreteNexus along with an expert panel as they explore how leaders across the value chain—aggregates, construction, and design—are setting the standard for low-carbon concrete in real projects. They will present practical strategies each stakeholder uses to drive embodied-carbon reductions without compromising performance, schedule, or cost. They will discuss what “excellence” looks like in 2026: the materials, specifications, and coordination practices that consistently deliver low-GWP outcomes.
Designing With Low-Carbon Concrete — What Architects & Engineers Need to Know for 2027
December 9, 2026
2 PM Eastern | 11 am Pacific
Online
Join host Lionel Lemay, Founder and CEO of ConcreteNexus along with an expert panel as they explore how designers can confidently specify low-carbon concrete using clear performance data, EPDs, and realistic GWP targets. They will present what producers are actually able to deliver in 2026: mix performance, SCM availability, ACI compliance, and carbon reduction pathways. They will discuss how architects, engineers, and producers can align early in design to meet LEED v5, Buy Clean, CALGreen, and owner-driven carbon goals without adding project risk.
EVENTS
Responsible Sourcing in Healthcare: Certifications That Support Better Material Decisions
Green Building Initiative (GBI) Webinar
September 9 – 11:30 am – 1:00 pm Eastern
Online
Healthcare projects rely on materials such as steel, concrete, vinyl, wood, natural stone, and ceramics. As organizations seek greater transparency and sustainability in their supply chains, third-party certification programs can help verify responsible sourcing practices and support informed procurement decisions. Join Green Building Initiative and the Responsible Sourcing Collaborative for a panel discussion featuring representatives from the Vinyl Sustainability Council (VSC), Sustainable Forestry Initiative (SFI), Concrete Sustainability Council (CSC), American Institute of Steel Construction (AISC), Natural Stone Institute (NSI), and Tile Council of North America (TCNA). Using healthcare project examples, panelists will discuss how leading certification and accreditation programs can support sustainability, resilience, quality assurance, supply chain transparency, and Green Globes certification goals while helping project teams make more responsible material choices.


Will AI Agents Specify, Design, Source and Build the Next Generation of Sustainable Concrete Construction?
AggNexus Digital Innovation Conference
September 15-17, 2026
University of Texas, Thompson Convention Center, Austin, TX
Agentic AI is moving beyond simple prompts and chatbots toward autonomous systems that can plan, analyze, optimize, and document complex workflows. This panel will explore how agentic AI could transform the future of responsibly sourced and low-carbon concrete—from interpreting project specifications and optimizing mix designs to evaluating embodied carbon, generating EPD and sourcing documentation, supporting procurement decisions, and improving construction outcomes. Panelists will discuss what is possible today, what may be feasible in the near future, and where human expertise, verification, and judgment remain essential. The session will focus on practical applications for the aggregates, cement, concrete, and construction materials industries, with an emphasis on sustainability, digital transformation, and responsible decision-making. The discussion will be moderated by Lionel Lemay, PE, SE, LEED AP, Founder and CEO of ConcreteNexus LLC and Director, Market Development – Concrete Sustainability Council.


Advancing Net Zero Goals Through Responsible Sourcing of Concrete
Net Zero Conference 2026
October 8, 2026 | Los Angeles Convention Center
Concrete’s global scale makes it essential to any credible net zero strategy. Responsible sourcing provides a practical, verifiable pathway to reduce the material’s carbon footprint while improving transparency and performance across the supply chain. Certification frameworks such as the Concrete Sustainability Council (CSC) help project teams evaluate environmental stewardship, ethical practices, and continuous improvement from raw materials through ready mix production. By prioritizing lower carbon cement blends, optimized mix designs, renewable energy, efficient quarry operations, and circular practices like recycled aggregates, responsible sourcing directly reduces embodied carbon. It also supports compliance with LEED v5 and emerging owner requirements for low carbon procurement. This session, presented by Lionel Lemay of Concrete Sustainability Council and Lawson Sanford of Climate Earth, will show how responsible sourcing accelerates market transformation and enables concrete to meaningfully contribute to global net zero commitments.
