Researchers in Brazil have developed a treatment system that can convert pig waste into potable water, addressing both environmental pollution and water conservation. The initiative, led by the Brazilian Agricultural Research Company (Embrapa), aims to minimize the contamination of rivers by pig feces and urine while also experimenting with turning this waste into other products, such as beer. Although the beer produced from this process will not be sold commercially, it highlights the innovative uses of the system.

The Treatment System for Swine Waste (Sistrates) is already being utilized by several pig farmers, where the treated water is primarily used for cleaning installations or returned to rivers in compliance with environmental standards, rather than for human consumption. This ensures that while the system helps in managing waste effectively, it also contributes to maintaining water quality in the surrounding areas while reducing reliance on fresh water sources.

In experimental batches, 40 liters of this unique beer were produced and tasted at scientific events in 2024 and 2025, showcasing not only the system’s capabilities but also providing a conversation starter about sustainability in agriculture. Brewer Fernando Cavass expresses interest in the initiative, suggesting its relevance in discussions around sustainable practices in food and beverage production, sparking curiosity about the potential for broader applications of such wastewater treatment technologies.
