At Prismane Consulting, one question comes up in nearly every conversation we have with coating manufacturers, raw material suppliers, technology developers and investors.
When will bio-based coatings become commercially competitive?
After several years of tracking this market, our assessment is that the industry has been asking the wrong question, and that this is precisely why it keeps arriving at unsatisfying answers.
The prevailing assumption has been that bio-based coatings are waiting on chemistry. Once the technology matures, the thinking goes, adoption will follow. That explanation is comfortable, and it is now out of date. The chemistry has advanced considerably. Commercial products are already on the market, particularly across Europe. Bio-based coatings are no longer constrained primarily by technology. They are constrained by economics, and specifically by a carbon pricing gap that no amount of laboratory work will close on its own.
This distinction matters enormously for anyone allocating capital in this space, and it is worth setting out plainly.
Demand Is Not the Constraint
Let us dispose of one misconception first, because it distracts from the real issue.
Demand for sustainable coatings is genuine, and it continues to strengthen. Net zero commitments, tightening regulation of volatile organic compounds and hazardous substances, circular economy initiatives and ESG driven procurement are all reshaping purchasing behaviour across the value chain. Manufacturers in construction, automotive, packaging, appliances and industrial equipment are actively seeking coating solutions that reduce environmental impact without sacrificing performance.
The demand exists. Adoption is nevertheless slower than almost anyone forecast five years ago.
When intent is strong and uptake is weak, the binding constraint sits somewhere else. In our view it sits in the economics.
The Economics of Bio-Based Coatings Matter More Than the Chemistry
One of the clearest articulations of this problem came recently from Thomas Lüder of Beckers Group, speaking at the Biobased Coatings Europe conference in Düsseldorf. His analysis aligns closely with what our own coverage of the coatings value chain has surfaced, and it deserves wider circulation.
The problem is not that bio-based coatings cost more in the abstract. The problem is that they deliver carbon abatement at a cost above what the value chain currently pays for carbon abatement.
The numbers make this concrete. The green premium on low carbon cold rolled steel in Europe sits at roughly 125 EUR per ton. Work backwards from that and it implies the coil coating value chain values carbon abatement at somewhat below 100 EUR per ton of CO2 equivalent. That figure is not arbitrary. It is a ceiling, and it has already been set by the steel value chain sitting above the coating.
Now measure today's bio-based raw materials against that ceiling. On the evidence Beckers has published from its own evaluations, they largely sit above it.
That single comparison explains more about the state of this market than any discussion of resin chemistry. Customers are willing to pay for carbon abatement. They are simply not willing to pay what bio-based coatings currently charge for it.
We find this framing useful because it turns a vague grievance into a solvable equation. There are exactly two ways to close the gap. Either the cost of the abatement that bio-based materials deliver comes down, or the value the market assigns to carbon abatement goes up. Every credible pathway to commercialization is a variation on one or both of those movements. Anything else is noise.
The Regulatory Blind Spot Almost Nobody Is Pricing In
This is the point we would most want a client to absorb, because it is consistently underweighted in commercial forecasts.
Regulation has historically been the single most effective mechanism for closing cost gaps on sustainable alternatives. Renewable energy, electric vehicles, recycled plastics. In each case, policy translated an environmental priority into a market price, and the economics reordered themselves around it.
That mechanism does not currently exist for coatings.
Consider what is arriving in Europe. The Construction Products Regulation (CPR), the Energy Performance of Buildings Directive (EPBD) and the Ecodesign for Sustainable Products Regulation (ESPR) are all consequential, and all will reshape construction materials. Every one of them regulates the building element or the finished product. None of them regulates the coating applied to it.
The regulatory pressure lands on the layers above the coating and stops there. Coating level de-fossilization sits in a blind spot.
The consequence is structural, and we will state it bluntly. The cost gap will continue to close more slowly than the technology matures, and it will keep doing so until a coating specific mechanism exists. Any commercial forecast assuming that regulatory tailwinds arrive on the same timetable as the chemistry is, in our assessment, mispriced.
The Other Barriers Are Real, but Secondary
We do not want to dismiss the remaining obstacles. We want to rank them correctly, because misranking them leads to misallocated investment.
Performance Requirements
Industrial coatings must deliver long term protection against corrosion, ultraviolet exposure, chemical attack, temperature cycling and mechanical wear, frequently across decades of outdoor service. A modest durability shortfall becomes a maintenance cost or a premature failure somewhere downstream. Bio-based polyester binders and hybrid resin systems have improved substantially and increasingly meet demanding specifications, though consistency across the full range of industrial applications is still developing.
Feedstock Availability
Renewable feedstocks contend with seasonal availability, agricultural variability, regional concentration and competition with food production. Petrochemical feedstocks contend with none of these, because several decades of capital investment have already resolved them. Security of supply remains a legitimate concern for any manufacturer contemplating a commercial scale switch.
Manufacturing Infrastructure
Existing coating plants are optimised for established resin technologies. Moving to alternative chemistries typically triggers reformulation, additional testing, customer requalification and process modification before commercial production can begin. These transition costs delay adoption even where technical performance is already satisfactory.
Sustainability Has to Be Demonstrated
Renewable content does not automatically translate into lower environmental impact, and serious buyers have stopped assuming that it does. Leading manufacturers now assess products through full Life Cycle Assessment covering carbon emissions, energy consumption, water usage, waste generation and end of life performance. Only bio-based coatings that demonstrate measurable, whole lifecycle improvement will earn broad commercial acceptance. The label alone is no longer an argument.
Note what these four have in common. Each is a cost problem wearing a different set of clothes. Solve the abatement economics and most of them become tractable. Leave the economics unsolved and none of them matters, because nothing reaches scale regardless.
What Would Actually Accelerate Adoption
Three levers. None of them sits inside any single company.
Lower Feedstock Costs
As bio-based production capacity expands and supply chains mature, unit costs fall, and abatement cost falls with them. This is happening. It is happening more slowly in chemicals than in adjacent sectors, and we would advise clients to plan against the slower curve rather than the optimistic one.
Coating Specific Policy
This is the most direct intervention available. A renewable content quota for chemical products, to take the obvious example, would guarantee demand at a defined level and rewrite the value calculation for bio-based raw materials immediately. We would watch this space closely. When it moves, it will reprice the market faster than a decade of incremental cost reduction.
Collaboration Across the Value Chain
This is the only lever a company can pull today without waiting for policy or cost curves to cooperate. Integrated partnerships linking renewable chemical producers, resin manufacturers, additive suppliers, coating formulators, equipment manufacturers and end users are how the preconditions for scale get built in practice. Firms doing this now are buying themselves optionality for the moment the other two levers finally move.
Where Bio-Based Coatings Adoption Will Begin
Commercial adoption will start where sustainability commitments are strongest and where customers are already prepared to recognise environmental value in a purchase decision.
Building and construction continues to prioritise low emission architectural and building material coatings. Automotive OEMs are pursuing lower carbon primers, topcoats and protective systems across vehicle production. Packaging brand owners keep substituting renewable content to defend their sustainability positioning. Appliances and consumer goods manufacturers are responding to both regulation and consumer expectation.
These four remain the most likely early adopters of commercially viable bio-based coating technology.
What We Would Tell a Client Today
Bio-based coatings will not displace conventional systems in a single step, and any strategy built on that premise is a strategy waiting to be disappointed. The realistic path is a gradual, hybrid transition, with formulations blending renewable and conventional raw materials becoming steadily more common as economics and supply chains mature.
So, the strategic question is no longer whether bio-based coatings will matter. It is how to be positioned when the economics finally cross the line, given that the crossing will be driven largely by forces outside your control.
Our advice is consistent on three points.
Build capability before the market rewards it. Formulation capability, supply chain partnerships and credible lifecycle data take years to develop and cannot be acquired on the day a regulation lands.
Treat coating specific policy as the variable most likely to reprice this market and monitor it with the seriousness that implies rather than as background noise.
Govern by the right metric. Measure every bio-based option on your table by its carbon abatement cost per ton of CO2 equivalent, benchmarked against what your customers actually pay for carbon today. That number, not the renewable content percentage on the technical data sheet, determines whether a product sells. In our experience, the firms that have internalised this are making noticeably better portfolio decisions than those still optimising for bio-content.
The transition to sustainable coatings will be decided by economics, not by chemistry alone. Understanding those economics before the rest of the market reaches the same conclusion is, we believe, a genuine source of competitive advantage.
