Bio-Based Epoxy Resin Global Market Report 2025

The bio-based epoxy resin market size has grown strongly in recent years. It will grow from$3.59 billion in 2024 to $3.88 billion in 2025 at a compound annual growth rate (CAGR) of 8%. Growth during the historic period was driven by increasing environmental concerns about petroleum-based resins, expansion in green building and sustainable construction materials, government regulations encouraging bio-based chemicals, intensified research and development in bio-based polymers, and growth in automotive lightweighting efforts.

The bio-based epoxy resin market size is expected to see strong growth in the next few years. It will grow to$5.2 billion in 2029 at a compound annual growth rate (CAGR) of 7.6%. Looking ahead, growth in the forecast period is expected to be fueled by the development of high-performance bio-based resin formulations, rising investments in bio-refineries and green chemistry, expansion of circular economy and waste valorization initiatives, growing demand from the wind energy and aerospace sectors, and increased adoption across various industries. Key trends anticipated include exploration of novel feedstocks, technological innovations, advancements in bio-based curing agents, deeper integration in automotive lightweighting, and progress in biotechnology and chemical engineering.

The growing demand for renewable energy is anticipated to drive the expansion of the bio-based epoxy resin market in the coming years. Renewable energy refers to power derived from naturally replenished sources such as solar, wind, hydro, and geothermal energy. This increasing demand is largely fueled by the urgent need to cut greenhouse gas emissions, as countries and industries strive to shift away from fossil fuels to combat climate change and achieve international climate goals. Bio-based epoxy resin contributes to renewable energy development by offering a sustainable, high-performance alternative to conventional petroleum-based resins used in wind turbine blades and solar panel components, improving durability while minimizing environmental impact. For example, in December 2024, Eurostat, a government agency based in Luxembourg, reported that renewable energy accounted for 24.5% of the European Union’s total energy consumption in 2023, up from 23% in 2022. Consequently, the rising demand for renewable energy is supporting the growth of the bio-based epoxy resin market.

Key companies in the bio-based epoxy resin market are working on the development of sustainable bio-based epoxy coatings using lignin as an eco-friendly substitute for harmful chemicals such as Bisphenol A, while ensuring high durability and performance. These bio-based epoxy coatings are environmentally friendly protective layers made by replacing traditional petroleum-derived substances with lignin, a natural polymer sourced from plant biomass, to reduce toxicity and increase sustainability without sacrificing functionality. For instance, in July 2024, AGC Vinythai Public Company Limited, a chemical manufacturer based in Thailand, partnered with Michigan State University (MSU), a U.S.-based academic institution, to create fully bio-based epoxy coatings that use lignin as a sustainable alternative to Bisphenol A. The collaboration aims to develop sustainable, 100% bio-based epoxy resins and coatings utilizing bio-based epichlorohydrin, thereby lowering the environmental impact of industrial resins while maintaining high standards of performance and safety.

In February 2022, Westlake Chemical Corp., a U.S.-based manufacturer of petrochemicals, polymers, and building products, acquired the epoxy business of Hexion Inc. for around $1.2 billion. This acquisition was intended to enhance Westlake’s integrated business strategy by broadening its presence in the specialty materials sector, particularly within the fast-growing epoxy resins market. It also aimed to diversify its product offerings, support a wider array of industries such as wind energy, coatings, and construction, and leverage synergies across its manufacturing, research, and distribution capabilities. Hexion Inc. is a U.S.-based company known for its expertise in producing bio-based epoxy resins.

Bio-based epoxy resin is an environmentally friendly alternative to conventional epoxy resin, formulated from renewable, plant-derived sources rather than petroleum-based feedstocks. These resins offer similar performance benefits - including strong adhesion, chemical resistance, and durability - while supporting sustainability initiatives.

Key types of bio-based epoxy resin include vegetable oil-based, soybean oil-based, cardanol-based, furan-based, lignin-based, and others. Vegetable oil-based variants are derived from natural sources like linseed, castor, or palm oil, which are converted into epoxy monomers to replace traditional petrochemical inputs. Common curing methods for these resins include thermal curing, ultraviolet (UV) curing, moisture curing, and chemical curing. Reactive diluents used in these formulations include bio-based glycidyl ethers and other bio-derived compounds. Bio-based epoxy resins are utilized across a range of applications such as paints and coatings, adhesives, composites, and laminates, serving end-use sectors including building and construction, automotive and transportation, wind energy, consumer goods, general industrial, and more.
