Hemp Rebar Market Report 2026

The hemp rebar market size has grown strongly in recent years. It will grow from $71.95 billion in 2025 to $76.09 billion in 2026 at a compound annual growth rate (CAGR) of 5.8%. The growth in the historic period can be attributed to increasing interest in alternative reinforcement materials, early experimentation with hemp-based composites, rising awareness of sustainable construction methods, limited initial production capacity, exploration of corrosion-free rebar options.

The hemp rebar market size is expected to see strong growth in the next few years. It will grow to $95.37 billion in 2030 at a compound annual growth rate (CAGR) of 5.8%. The growth in the forecast period can be attributed to rising demand for low-carbon building materials, expansion of bio-composite manufacturing technologies, increasing regulatory support for sustainable infrastructure, growing preference for corrosion-resistant reinforcement, accelerated investment in natural fiber innovation. Major trends in the forecast period include increasing shift toward low-carbon construction materials, expansion of automated fiber processing technologies, growing use of digital testing and simulation, rising adoption of automated manufacturing systems, increasing development of smart composite reinforcement materials.

The growing demand for green buildings is expected to drive the growth of the hemp rebar market. Green buildings, also known as sustainable or high-performance buildings, aim to minimize negative environmental impacts and maximize positive effects on occupants. Hemp rebar, utilized in green buildings, offers a potential alternative to traditional steel rebar with numerous environmental and performance benefits. The growth of hemp sequesters carbon, and the manufacturing process requires less energy, resulting in a smaller overall carbon footprint for the final product. For example, in July 2024, the U.S. Green Building Council, a U.S.-based non-profit organization, reported that in 2024, over 46,000 residential projects were certified under the LEED green building rating system, with new LEED residential project registrations in 2023 showing an increase of nearly 5%. This growing demand for green buildings is driving the expansion of the hemp rebar market.

The growth of the hemp rebar market is expected to be driven by an increase in infrastructure projects. Infrastructure projects encompass large-scale construction or development efforts aimed at building, upgrading, or maintaining essential facilities and systems that support a society or economy. Hemp rebar offers infrastructure projects a low-cost, non-corroding alternative to steel. For example, in 2023, the World Bank, a US-based international financial institution, reported that 68 countries received investments across 322 projects, up from 54 countries and 260 projects in 2022. Thus, the rise in infrastructure projects is fueling the growth of the hemp rebar market.

Leading companies in the hemp rebar market are focusing on developing innovative solutions, such as sustainable, bio-based reinforcement materials, to improve structural performance while minimizing environmental impact. These materials serve as eco-friendly alternatives to conventional steel or synthetic reinforcements and are made from renewable natural resources like hemp, flax, or bamboo, providing strength and durability while reducing carbon emissions. For example, in September 2025, FibreWerks Inc., a U.S.-based technology and manufacturing company, introduced Hemp Rebar, a plant-based reinforcement material designed to replace traditional steel rebar in concrete construction. Hemp rebar offers comparable strength to steel and naturally resists corrosion, extending the lifespan of concrete structures and lowering maintenance costs. Manufactured through a low-energy, eco-friendly process, it also sequesters carbon dioxide, significantly reducing overall emissions and positioning itself as a sustainable solution for green building and global infrastructure projects.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs are impacting the hemp rebar market by increasing import costs for hemp fibers, bio-resins, and processing equipment, leading to higher production costs and delayed adoption in construction and aerospace applications. Regions depending on imported hemp raw materialssuch as Europe and parts of Asiaface heightened supply chain constraints. However, tariffs are also encouraging domestic cultivation, localized manufacturing, and innovation in bio-composite reinforcement materials, supporting long-term market resilience.

This hemp rebar market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.

Hemp rebar is a construction material crafted from processed hemp fibers, serving as a reinforcing element in concrete structures. It is engineered to deliver strength and durability similar to traditional steel rebar. Additionally, hemp rebar boasts advantages such as being non-corrosive and has the potential to contribute to reduced greenhouse gas emissions.

The primary types of hemp rebar include processed hemp fiber and raw hemp fiber. Processed hemp fiber is a natural fiber extracted from the stalk of the hemp plant. It is obtained through the separation of the outer bark from the inner woody core of the hemp plant. Processed hemp fibers are manufactured in various bar sizes, such as 0.25 Inch x 4 Feet, 0.375 Inch x 4 Feet, 0.5 Inch x 4 Feet, and 0.625 Inch x 4 Feet, and find applications in construction, automotive, and aerospace industries.North America was the largest region in the hemp rebar market in 2025.
