CarbonBuilt

Produces ultra-low carbon concrete blocks

Overview

CarbonBuilt makes ultra-low carbon concrete blocks and sells associated carbon credits to decarbonize construction. The blocks cut concrete’s carbon emissions by 70% to 100% without raising production costs and still meet performance needs, with Environmental Product Declarations to help producers win bids and ESG/LEED benefits for builders, plus high-quality carbon credits for buyers that permanently avoid CO2. Unlike some competitors, it offers blocks that are cost-competitive with traditional blocks and provides industry-leading EPDs and carbon credits across producers, builders, and buyers. The goal is to reduce the concrete sector’s carbon footprint across the construction industry by delivering affordable, verifiable low-carbon blocks and credits that accelerate decarbonization.

CarbonBuilt reshapes Jolley plant methods and branding

CarbonBuilt reshapes Jolley plant methods and branding. Los Angeles-based CarbonBuilt Inc., a developer of processes lowering the carbon dioxide emissions associated with conventional concrete masonry unit production, is molding block using its Reversa binder technology at a wholly owned, Danielson, Conn. operation. Ratings gleaned from the Building Transparency Embodied Carbon in Construction Calculator (EC3) indicate CarbonBuilt block have the lowest carbon factor of any block produced in the U.S. "This is a defining moment for CarbonBuilt," says CEO Michelle Carvin. "With the conversion of the Danielson plant complete, we're demonstrating how our innovative Reversa technology combined with more efficient operating processes are transforming the future of concrete masonry. We are producing high-performing block with dramatically lower carbon emissions. Building owners, architects, general contractors, and masons across the Northeast can now source concrete masonry units that deliver exceptional quality and a meaningful climate impact, without paying a premium." Made from a proprietary blend of upcycled industrial materials, Reversa replaces traditional carbon-intensive cement in concrete production, dramatically reducing its carbon footprint. Through the replacement of up to 50 percent of cement in CMU mix designs with Reversa, waste reduction and targeted operational upgrades, CarbonBuilt is improving product quality while reducing the plant's carbon footprint by as much as 70 percent. Since acquiring the Jolley Concrete and Block plant in Danielson, CarbonBuilt has invested in operational efficiency, strengthened product quality, and reduced both cement usage and material waste. The facility has annual production capacity of 80,000-plus tons and is poised to offer low carbon segmental retaining wall units and architectural masonry products in the near term.
