The next feedstock war: Why the feed industry is fighting energy for waste

The global race to decarbonise industry has triggered an unexpected, high-stakes collision between aviation fuel producers, livestock feed manufacturers, and agri-food giants. The prize? 

Waste-derived raw materials.

What was once dismissed as low-value garbage, used cooking oils (UCO), animal fats (tallow), agricultural processing residues, and industrial fermentation side-streams, is now one of the most fiercely contested resource pools in the global bioeconomy.

According to the UNEP and FAO Food Waste Index, the world discards roughly 1.05 billion tonnes of food waste annually. Historically, the commercial feed sector acted as the primary circular valve for these materials, processing industrial co-products into nutritious rations.

However, as aggressive Sustainable Aviation Fuel (SAF) mandates roll out across Europe and North America, a massive influx of energy capital is aggressively poaching these exact waste streams. The animal nutrition sector now faces an existential challenge: adapt and innovate, or find itself priced out of its own circular supply chains.

The Fuel Subsidy Threat to Feed Costs

At the core of this industrial collision is an asymmetric financial battle. For decades, the global animal feed industry, which manufactures over 1.29 billion metric tons of compound feed annually, depended on predictable, lower-cost access to agricultural by-products and processed fats to keep livestock rations affordable.

But the energy sector’s appetite for these inputs has expanded exponentially. According to recent market data, global biofuel production now consumes over 23 million metric tons of collected UCO annually, leaving just a fraction for alternative industries like animal feed and oleochemicals.

End-Use Application	Estimated Annual Vol (Million Metric Tons)	Percentage Share	Primary Market Drivers
Biofuels (SAF & Biodiesel)	~23.0	~67.6%	SAF mandates, LCFS credits
Oleochemicals & Lubricants	~5.6	~16.5%	Bio-plastics, soaps, surfactants
Animal Feed & Rations	~2.8	~8.2%	Caloric density in livestock diets
Other Uses (Reprocessed/Misc)	~2.6	~7.7%	Secondary non-commercial cooking

Because SAF and renewable diesel producers enjoy massive government tax credits and blending mandates, they can absorb higher feedstock prices. A commercial aviation industry scrambling to hit its target of 500 million tonnes of SAF by 2050 can easily outbid a livestock producer operating on razor-thin margins.

When advanced pretreatment facilities, like the facility commissioned by BDI-BioEnergy International and Ghent Renewables at North Sea Port, upgrade highly contaminated waste streams into pristine fuel precursors, they effectively strip the feed industry of its traditional safety valve: low-quality, cheap lipid streams.

Redesigning the Ration: Feed Companies Pivot to Circularity

Faced with the threat of being priced out of conventional lipid and agricultural waste markets, major feed and animal nutrition companies are shifting from passive consumption to an aggressive, tech-driven approach to circularity. The goal is no longer just hitting emissions targets; it is protecting long-term margin security.

Rather than competing head-to-head for finite pools of used cooking oil and tallow, the animal nutrition sector is scaling up proprietary biotech alternatives.

Biotechnology companies are successfully converting industrial forestry and food processing effluents into high-value nutrition. For instance, biotech pioneer Enifer is commercialising its proprietary PEKILO® process. This technology uses specialised fungal fermentation to transform agricultural and forestry byproducts directly into nutrient-dense, high-protein ingredients designed for aquafeed and pet food applications.

Advanced technology pioneers like Innovafeed are bypassing traditional agricultural resource loops entirely. By utilising localised, non-lipid organic waste residues as a direct substrate to breed black soldier fly larvae, they can generate massive volumes of premium insect protein. The resulting structural oils and protein fractions are highly scalable and precision-tailored to replace volatile conventional inputs in poultry and aquaculture diets.

Pioneering firms like Calysta are leveraging sophisticated gas-fermentation systems to turn methane and low-value inputs into high-quality protein fractions. By feeding naturally occurring microbes a blend of gas and basic nutrients, they can continuously harvest pure protein. This bio-industrial approach completely decouples global feed production from traditional, climate-vulnerable land and water constraints.

Concurrently, industry giants like Nutreco (via Skretting and Trouw Nutrition) and dsm-firmenich are deploying precision-formulation software. These digital tools allow nutritionists to instantly swap out volatile, heavily contested fats for upcycled alternative ingredients the moment fuel markets drive up prices.

Meanwhile, originators like ADM and Cargill are rapidly verticalizing their supply chains to capture, treat, and retain agricultural co-products internally before they can escape to external energy brokers.

The New Geopolitics of Biomass

The restructuring of waste markets has also fundamentally shifted how agribusiness views supply chain resilience. The compounding shocks of the war in Ukraine and volatile trade corridors in the Middle East laid bare the deep vulnerabilities of globalised feed grain and fertiliser distribution.

As a result, waste-derived raw materials are no longer evaluated solely on their green credentials; they are now highly prized as geographically insulated assets. A ton of locally sourced cassava peel, fruit processing pulp, or domestic food waste represents an uninterrupted, tariff-free unit of nutrition.

By scaling up localised “waste-to-feed” upgrading technologies, the livestock sector can insulate itself from macro commodity shocks while driving a true regional circular economy.

Competitiveness in a Finite World

The overarching transformation occurring across the agri-food landscape is a deep philosophical pivot. Waste is no longer an environmental liability to be mitigated or discarded; it is an economic prize to be defended.

The animal feed industry is discovering that its historical claim to agricultural by-products is no longer guaranteed. If the sector fails to scale its own waste-valorisation pipelines, the energy industry will gladly buy up those resources to fuel commercial aviation fleets.

For livestock producers and feed millers globally, winning this feedstock war is no longer a matter of sustainability branding. It is the defining variable for long-term competitiveness, biosecurity, and survival in a resource-constrained world.
