The production of 50,000 metric tons annually of single-cell protein by Unibio in Saudi Arabia represents a breaking point in the food value chain. This facility, powered by local natural gas, aims to reduce imports of animal feed, an industry that saw a $26 billion agricultural debt in Turkey in 2025. The initial capacity of 50,000 metric tons, with expansion to 300,000, generates an alternative biomass flow compared to traditional intensive farming systems.
The choice of Saudi Arabia is not random: the country has a natural gas availability that allows for low-cost energy production. However, the comparison with the Turkish case reveals a contradiction: while Turkey’s agricultural debt grows due to climate and geopolitical shocks, Saudi Arabia invests in infrastructure to reduce its food vulnerability. This contrast highlights an information asymmetry between emerging markets and strategies of food sovereignty.
The Totem and Its Tension
The Unibio model is based on superior thermodynamic efficiency compared to animal protein production. The fermentation of natural gas requires 3 MJ/kg of energy, compared to the 15 MJ/kg needed for intensive farming. This energetic advantage allows a greater buffer capacity relative to seasonal crop systems. However, expansion to 300,000 metric tons requires precise water risk management: the facility needs 12 m³/s of deionized water for the fermentation process.
The comparison with the Turkish sector reveals another tension: while Unibio seeks to reduce foreign dependency, Turkey’s agricultural debt has increased due to feed imports. This demonstrates that technological transition is not automatic. The $26 billion in Turkish debt represents a marginal cost that could only be reduced by investments in local production infrastructure, such as those proposed by Unibio.
Crossing the Threshold
The critical threshold for Unibio lies in the relationship between production capacity and actual demand. With 300,000 metric tons annually, the facility could meet 15% of global protein feed demand. However, product registration in Europe and Saudi Arabia represents a regulatory constraint that may delay return on investment. The system’s buffer capacity will depend on the speed of approval in other markets.
For the Turkish sector, the threshold for financial sustainability is around an irrigation rate of 8 m³/s. Beyond this threshold, irrigation costs exceed crop value added. This physical limit highlights the fragility of the current model, which depends on feed imports at $1200/ha, a cost that may not be sustainable in the long term.
For investors, Unibio‘s model represents an opportunity for diversification from traditional agricultural assets. Single-cell protein production has an estimated internal rate of return (IRR) of 18%, surpassing the sector’s average 12%. However, water risk requires a detailed life cycle analysis of the product, with particular attention to deionized water availability.
In my view, the gap between sustainability narrative and physical reality is not an error but a strategic choice. While the Turkish sector finds itself in a debt trap, Unibio‘s approach demonstrates that variations in energy efficiency can generate economic value. Investors should evaluate these systems’ buffer capacity relative to production marginal costs rather than following market narratives.
