Hemp was never all that rare. Long before it was banned and stigmatized, this ancient plant was already part of daily life, used in textiles, ship sails, ropes, paper, and even building materials. Today, in 2025, hemp is back in the spotlight of the global economy, but this time in a form that’s shaking up the sustainable construction industry: hempcrete (as in, hemp concrete.)
Hempcrete—a mix of hemp fibers, lime, and water—emerges as an eco-friendly alternative to traditional concrete. It’s lightweight, breathable, insulating, and even absorbes carbon.
This isn’t just a passing trend. A new report from Global Market Insights confirms that in 2024 the global hempcrete market hit $570.2 million, and is projected to reach $2.24 billion by 2034, growing at a compound annual rate of 14.9%.
In the context of a climate crisis, hemp is positioning itself not just as a regenerative crop, but also as a strategic material for reimagining the housing of tomorrow.
A market already making waves
Beyond the total figure, it’s worth breaking down how this market is shaping up:
$383.7 million – Lime-based binders: Hempcrete doesn’t stand on hemp alone; it needs a “glue.” Lime plays that role, mixed with fibers and water to give the material structure and strength.
$338.1 million – Residential construction: A large share of hempcrete goes into housing, especially one- or two-story homes, where it works perfectly as insulation and wall infill.
$279.7 million – Cast-in-place systems: This method takes the fresh hemp-lime-water mix directly to the construction site, poured into formwork where it hardens in place. It’s flexible and allows for custom designs.
$335.3 million – Walls and structural infill: Among the most popular uses, since hempcrete offers excellent thermal and acoustic insulation. In practice, it’s used as filler within walls that already have wood or metal framing.
