Algae Will Not Fix Your Soy Problem. It Might Fix Your Egg.

On 5 January 2026 the Brazilian vegetable oil association Abiove announced that its members were leaving the Amazon Soy Moratorium, the voluntary pact that for two decades kept soy grown on land cleared after 2008 out of the export chain. The members include Cargill, ADM, Bunge and Amaggi, firms that together handle close to 45% of Brazil's soy exports, Mongabay reported. The Amazon Environmental Research Institute estimates that abandoning it could push Amazon deforestation up by as much as 30% by 2045.

Most coverage read this as Brazilian state politics. If you buy feed protein into the European market it is a compliance story, and the timing is unkind. The EU Deforestation Regulation starts applying to large and medium operators on 30 December 2026, with micro and small enterprises following on 30 June 2027, as the latest postponement confirms. The private control layer is coming off in the same year the public one goes on.

So the question lands on a lot of desks at once, and it is almost always the same question: can algae replace the soy. The honest answer is no. The more useful answer is that it is the wrong question.


What the moratorium was actually doing for you

The soy in European chicken is not a rounding error. In 2020 the EU27 plus the UK imported 33.9 million tonnes of soy products, with Brazil supplying 48%, and broiler feed was the single largest use at roughly 41% of all feed soy, around 13 million tonnes, according to WWF's mapping of the European soy supply chain. The same report puts embedded soy in chicken at 956 grams per kilogram of retail weight meat. A kilo of chicken is very nearly a kilo of soy.

It is worth being precise about what soybean meal is, because it gets described as a residue. It is not a byproduct in any meaningful sense. A soybean is roughly 80% meal and 20% oil by mass, and while meal used to carry about two thirds of the crush value, oil now takes around half of it on the back of biofuel demand, as feed nutritionists in the sector put it. You are not displacing a waste stream. You are displacing the commercial core of a global crop, with an amino acid profile every formulation model in the industry is tuned around.

The exposure attached to it is measurable. Trase data cited by WWF attributes about 1.5 hectares of deforestation and conversion to every 1,000 tonnes of Brazilian soy imported into the EU between 2009 and 2018, roughly double the rate carried by Chinese imports from the same origin. The moratorium is what made a deforestation free claim on that volume cheap to make. Without it the claim has to be built from geolocation and due diligence on your own account, on a deadline, in a market where the traders who used to underwrite it have stepped back.


The 2026 answer on substitution

The cleanest test of the substitution question was published this year. Fanari and colleagues replaced 30% of the crude protein from soybean meal with Nannochloropsis oceanica in broiler diets and ran it for 35 days, publishing in Foods. Every performance variable was impaired: lower body weight at day 35, lower daily gain, lower feed intake, worse feed conversion, lower European Production Efficiency Factor. There was no significant difference at day 10, so the penalty accumulates rather than announcing itself early. Meat quality held apart from colour, and the meat gained EPA and carotenoids.

A 2025 study in the Journal of Animal Physiology and Animal Nutrition points the same way from another angle, reaching for extrusion and enzyme superdosing simply to manage the metabolic impact of 20% chlorella inclusion. That is a processing problem, not a bargain.

Now hold that against the low dose evidence. In Scientific Reports, Nannochloropsis oculata at 0.5% and 1.0% in laying hens under heat stress improved egg number, egg weight, egg mass, feed conversion and mortality. In the International Journal of Molecular Sciences, 0.1% spirulina in reduced protein broiler diets improved feed conversion across the full cycle with no loss of body weight.

The same alga wrecks feed conversion at 30% of dietary protein and improves it at 1%. A 2021 review in the Journal of Animal Science and Biotechnology puts the beneficial broiler window at roughly 1.5% to 10% of the diet, with performance falling away beyond it, and names cell wall digestibility as the reason. Algae is a functional ingredient with a dose response, not a protein commodity. Cross the dose and you are not buying more benefit, you are buying a problem.


Why the feed budget can never pay for it

Here is the constraint that decides everything downstream. Soybean meal traded at about USD 404 per tonne in March 2026 on the World Bank series, roughly 40 cents a kilo. Delivered feed grade microalgal powder sits one to two orders of magnitude above that.

At those multiples the arithmetic is brutal and simple. Any inclusion rate high enough to displace meaningful soy protein costs more than the entire feed budget it was supposed to improve. Even the modest functional dose has to earn its place against a feed cost the buyer is measuring in single euros per tonne.

This is why almost every algae in feed conversation stalls. The person on the other side of the table is pricing protein and energy, and against that yardstick the ingredient is simply expensive. The way out is not a cheaper alga. It is a different buyer.


Where it does pay: the egg

Switch from the feed budget to the product the consumer picks up, and every number in this article changes sign.

Start with the regulatory lever, because it is the part most people miss. Under EU nutrition claims rules, a food may be labelled a source of omega 3 fatty acids at 40 mg of EPA plus DHA per 100 g, and high in omega 3 fatty acids at 80 mg. Those are thresholds, not a scale. Cross one and the pack changes. Everything above it is chemistry the label cannot use and the shopper cannot see.

An egg starts unusually close to that line. Ordinary eggs already sit around 52 mg of EPA plus DHA per 100 g, so a small dose moves a product that is nearly there into a category it can advertise. Feed Nannochloropsis oceanica at 3% of a layer diet and eggs reach about 105 mg DHA and 5 mg EPA per 100 g, with transfer efficiency running from 85% down to 60% over four weeks, as published in Applied Sciences. That clears the high omega 3 threshold with room to spare. There is no comparable lever in broiler meat, which is a large part of why eggs are where this works.

Note what that means for strain choice. Nannochloropsis is an EPA producer carrying very little DHA, and the eggs still gained DHA, because hens elongate EPA themselves. And you do not need to out deposit the DHA rich alternatives, which saturate above 20 g/kg anyway, reaching 223 mg per yolk at that rate and only 253 mg at double it. The competition is against a regulatory number, not against another supplier's fatty acid profile. That opens the field to strains a deposition contest would rule out.

Then the cost. On a hen eating about 110 grams a day and laying about 0.9 eggs a day, 3% inclusion adds somewhere between a few cents and about ten cents per egg at realistic ingredient prices. Enriched eggs carry retail premiums comfortably above that. The cost is funded by the egg price rather than the feed budget, which is the only structure in which any of this works.

And here the case gets better than a single claim, because one ingredient is doing three jobs at once.

The omega 3 claim is the one you sell. The carotenoids ride along in the same biomass and do visible work on yolk colour, which packers already buy synthetic pigments to control, so a second input can come off the formulation while the first one goes on. And the bird itself benefits: at the very inclusion rates that create the claim, the Scientific Reports trial recorded better egg number, egg weight, egg mass, feed conversion and mortality. That last point is unusual and worth sitting with. Normally a claim ingredient is a cost you accept in exchange for the marketing. Here the additive that earns the premium also appears to improve the flock that produces it.

So the honest summary is not that algae is a cheaper protein, because it is not, and it never will be. It is that in the right product, at the right dose, a single ingredient can clear a labelling threshold, replace a pigment, and support the animal, and be paid for by a premium the consumer is already willing to pay. That is a real business case. It just is not the one people go looking for when they start from the soy problem.


Where BlueBurn fits

Most people come to us at one of four moments.

The first is the question this article has been circling: which alga, for which effect, at which dose. The species are not interchangeable and the differences decide the outcome. Nannochloropsis brings EPA, Schizochytrium brings DHA, spirulina brings protein and phycocyanin, chlorella behaves differently again, and brown seaweeds bring laminarin and fucoidan for entirely different reasons. Match the strain to the effect you are actually selling, then set the dose from the threshold or the response curve rather than from a brochure, then check the cost lands per unit of finished product rather than per tonne of feed. Getting that sequence wrong is the single most common reason these projects stall, and it is usually settled long before anyone talks to a producer.


The second is when supply gets hard. A key input turns scarce, a voluntary standard collapses, a trade route or a regulation rules out what you were using, and the question stops being whether algae is interesting and becomes who can supply a qualified, compliant alternative, at volume, by when. We shortlist verified algae producers and processors that genuinely meet your specification, and we walk you through the regulatory path in your destination market so the supply holds when it matters. In feed that specification is unforgiving: registered feed material status in the EU catalogue, contaminant control on heavy metals and iodine that survives an audit, stable composition batch to batch, and analytical substantiation that holds for every batch rather than for the trial.


The third is earlier and simpler: could algae replace something you already use, and would it stand up on cost. That is a BlueBurn Quick Scan. We look at your current formulation, flag which ingredients have a credible algae alternative, and give you supply and cost per substitution with a clear order of what to try first. In feed that usually means separating the bulk protein question, which is not live, from the claim bearing additive question, which is.


The fourth is the longer view: independent market analysis and roadmap planning for teams, and governments, deciding where algae fits over the next several years, and where it does not.


What sits under all four is hard to buy elsewhere. We are inside the institutions shaping this sector, as members of the European Algae Biomass Association (EABA) industry commission and the European standards committee CEN/TC 454 Algae and algae products. We are not watching the market from the outside. We are helping write the standards by which it operates.

So if a supply problem, a formulation question, or a roadmap is live for you, get in touch. Tell us what you are working on, and we will tell you which alga fits, what timeline is realistic, and which producers we would put on your shortlist.
