Sustainably produced milk with guaranteed origin

Right from the start, Osmar and Carmen Trevisan searched for a way to improve efficiency, enhance animal well-being and enable the sustainable processing of animal waste on their dairy farm. Convinced by GEA’s holistic solution, the family farm initially invested in a GEA free stall barn including its system technology for intelligent manure management some years ago. The farm's latest project, a new production line for milk processing, guarantees low energy consumption, minimizes the carbon footprint and adds a guarantee of origin. Thanks to a long-term partnership, GEA was again selected as a partner for this project.

With GEA milking technology components and Holstein dairy cattle, the family farm initially produced 1,500 liters of milk a day. The Trevisan farm now produces 13,000 liters of milk daily with a herd numbering 900 animals, with 370 lactation cows at their new location in Farroupilha in the state of Rio Grande do Sul in southern Brazil. To optimize the animal’s living conditions, the free stall barn provides animal-friendly equipment from A to Z: Ventilators, sprinkler systems, a fresh water supply and rubber mats noticeably enhance animal comfort. The relaxed atmosphere in the barn and the cows’ well-being has a positive effect on milk performance.

Sustainability and environmental friendliness were also considered when processing the manure. GEA’s liquid manure technology therefore consists of a scraper system ensuring dry walkways continuously and improving the hygiene standard in the barn. The resulting mass is first homogenized in pump and agitator systems. Subsequently liquids and solids are processed in separators, screens and presses. As valuable compost as well as liquid fertilizer for growing grain, the processed liquid manure replaces artificial fertilizers. In addition, the high-energy material is used in Fazenda Trevisan’s own biogas plant to produce electricity, which can then be used for the farm’s operational processes.

“Processing our own milk and marketing it successfully in the region was another important goal,” says Jean Carlos, one of Trevisan’s sons, explaining the investment in the farm’s own dairy. The GEA product line consisting of centrifuge, homogenizer and pasteurizing system increases the added value of the operation and opens the door to a segment of the dairy sector that will bring the family farm a significant increase in income in the long term. The dairy was installed right next to the milking facility to process the raw milk into high-quality dairy products in the shortest possible time and pack them. The fully automated GEA production line optimizes the workload for personnel and ensures the highly efficient, economical use of energy, water and operating resources for process control and plant hygiene. Thanks to processing the milk directly on the farm, transport routes are eliminated and cooling times minimized, with a positive effect on Fazenda Trevisan’s environmental impact.
