From soy to insects: how decentralized farming can revolutionize sustainable protein production

Black soldier fly larvae are paving the way for a new paradigm: transforming waste into value, thanks to local, modular facilities that combine efficiency, circular economy, and protein independence.

For decades, soy and fishmeal have been the pillars of the animal feed industry. Today, however, this model is increasingly showing its limitations: environmental pressures, price volatility, and growing global demand for protein are pushing the industry to rethink its foundations. The focus is no longer just on quantity — “more protein” — but on the quality and intelligence of protein sources.

In this scenario, alternative proteins are gaining ground, particularly those obtained from insects and single-cell microorganisms. These are not just new ingredients, but a real paradigm shift. The value of these proteins is no longer defined by production efficiency, but by their ability to fit into a circular economy model, reducing waste and environmental impact.

Insect farming, and in particular that of the black soldier fly (BSF), perfectly embodies this transformation. BSF larvae can convert organic waste and food by-products into high-value proteins, closing the nutrient cycle and transforming a problem—waste—into a valuable resource. This approach reduces pressure on traditional protein crops and creates new economic opportunities for local supply chains, from agriculture to aquaculture.

However, the sustainability of insect farming depends heavily on the choice of raw materials used. Extending authorizations for the use of by-products and diversifying supply sources are key steps in accelerating the transition to full circularity. Added to this is a crucial factor: logistics. Farms must be located close to waste sources, because transporting organic materials over long distances risks negating the environmental benefits.

This is where the decentralization of production systems comes into play. Modular and distributed plants are one of the most promising developments for the sector: they allow waste to be transformed into resources directly where it is generated, reducing costs and emissions. In this model, each node in the network contributes to the overall value: agricultural or agro-industrial by-products become food for larvae, which produce proteins, oils, and frass that can be used in feed and as natural fertilizers.

This decentralized paradigm combines economic efficiency and environmental regeneration, making protein production more resilient, scalable, and accessible even for medium-sized agricultural or livestock businesses. At the same time, it promotes shorter and more transparent value chains, capable of restoring balance between the economy, nature, and the territory.

Nutritionally, insect proteins offer an excellent profile: they contain all the essential amino acids, functional fatty acids such as lauric acid—known for its antimicrobial properties—and micronutrients that promote animal health and growth. These characteristics make it a viable alternative to fishmeal and plant sources, ensuring palatability, digestibility, and formulation stability in aquaculture, poultry, and pet food.

The push towards insect protein is therefore technical, cultural, and strategic. The global feed market, subject to ongoing geopolitical tensions and growing consumer awareness of sustainability, is looking for resilient, transparent, and low-impact protein sources. Black soldier fly larvae offer a concrete response to these needs, combining biological innovation, production efficiency, and circular logic.

Ultimately, the transition to a more sustainable food system also passes through here: from recognizing that waste is not an end point, but the beginning of a new production cycle. Insects teach us that nothing is wasted in nature — and that the future of protein could come from what, until recently, we considered waste.

Thanks to the spread of decentralized breeding facilities, this vision is not just an ecological ideal, but a concrete model of industrial innovation: a widespread network capable of generating local value, reducing distances, and restoring balance between the economy, the environment, and the community.
