Market Dynamics

Growth Drivers: Rising Demand for Sustainable Coatings and Expanding Bio-Refining Capacity

The market is being propelled by growing commercial demand for certified low-carbon paints and coatings, composites, and adhesives, enhanced capabilities for the manufacture of epoxidation and biorefining, increasing processing of cardanol and lignin-based feedstock streams, and rising applications in automotive lightweighting, wind turbine blade production, and electronics enclosures, without using BPA. As the number of companies that are announcing their carbon reduction goals increases continually, demand for supply of high-quality and high bio-content epoxy resins is expected to drive investments in capacities for production across the value chain.

Strategic supply and co-development agreements between paints and coatings, and composite manufacturers and suppliers of bio-based resins reinforce this trend, as downstream players increase their commitment to obtaining volume of renewable content ahead of the regulation-led phase-out of BPA. The growth of venture and corporate investments in bio-refining and cashew-processing capacities are also contributing to expansion of baseline production capacities, and collectively resulting in constantly growing demand throughout the forecast period.

Restraints: Feedstock Price Volatility and Performance Trade-offs Versus Petroleum-Based Epoxy

Volatility in prices of vegetable oil, cashew nut shell liquid, and lignin as feedstock remains an authentic constraint toward faster growth of the market as a whole, considering that smaller specialty players are not endowed with the same purchase volumes and hedging opportunities that large integrated petrochemical-based epoxy resin manufacturers have. This constraint has resulted in the fact that the only reliable large-scale production of such materials at stable prices is carried out by a relatively small number of financially sound firms, limiting the variety of suppliers for formulators.

Unresolved performance gaps between bio-based and regular petrochemical epoxy resins remain another significant constraint, since even with increasing share of bio-based ingredients, the resulting material may feature decreased heat resistance, increased viscosity, or longer processing time than the bisphenol A epoxy resin. To close this gap, further investments should be made into curing agents research and formulation technologies, which continue to evolve and require significant expenses.

Opportunities: Lignin Valorization and Expanding Wind Energy Composite Demand

Increasing investments in lignin valorization to a commercial scale is a truly critical one as suppliers no longer rely only on vegetable oil and cashew-derived raw materials, but are able to utilize plentiful and inexpensive byproducts of the pulp and paper industry. Manufacturers that will establish an advantage in technologies of lignin extraction, purification, and epoxidation will take a decent market share as the bio-based epoxy industry will go beyond specialized products toward the real industrial production of bio-based epoxy.

Another critical opportunity is connected with the expansion of the qualification of bio-based epoxy into wind energy and electric vehicle composite projects, as manufacturers of blades and vehicles are increasingly interested in resins that contain a high percentage of renewable materials. Manufacturers that will be able to provide infusion-grade bio-based epoxy that corresponds to Good Manufacturing Practice will receive more and more market shares due to renewable energy and vehicle electrification manufacturers recognize verified bio-based content as a real competitive factor.​​​​​​​
