Food Tech Company Divaks Selects Bühler to Develop Industrial-Scale Yellow Mealworm Plant

UZWIL, Switzerland, and VILNIUS, Lithuania — Lithuanian insect producer Divaks selected the Swiss technology group Bühler to build its first commercial-scale yellow mealworm plant. Scheduled to go into operation in 2025, the plant will produce up to 15,000 metric tonnes of sustainable insect-derived products annually. Bühler will be responsible for planning and executing the plant as well as providing solutions for the entire supply chain.

Following the establishment of its pilot facility in May 2022, Divaks has now taken a major step towards its first industrial-scale yellow mealworm plant. Divaks’ site, which is located in Lithuania’s Marijampolė Free Economic Zone, spans an area of 10,000 square meters. Encouraged by the opportunities in this market, the company said it expects to double its production in the new facility by 2030. 

In the new plant, Divaks will produce yellow mealworm (scientifically known as Tenebrio molitor), an environmentally friendly, nutritious protein source that can be used in applications including meat alternatives, sports nutrition, snacks and confectionery as well as premium pet food. The residue from the mealworm production (or insect frass) will be utilized as organic fertilizer, as it contributes to healthier soils, fostering a circular economy approach. 

Bühler will be responsible for all process technology for the plant, which will include feedstock preparation to provide safe, palatable and nourishing feed to the larvae and a fully automated larvae growth system with sophisticated climate control. Furthermore, Bühler will provide the processing line to transform the harvested larvae into textured insect proteins (TIP), insect protein concentrates (IPC) and other specialized food ingredients.  

Kęstutis Lipnickas, Divaks CEO and co-founder, said, “This is a huge step forward for Divaks as we work to establish ourselves as global leaders in high-quality insect-derived ingredients for human nutrition. Bühler will deliver the state-of-the art technology we need, allowing us to focus on the most important activities: market development and creating sustainable products that excel in nutritional and functional qualities.” 

Andreas Baumann, head of market segment insect technology at Bühler, added, “We are delighted to have been chosen to provide a full-scope solution for Divaks’ yellow mealworm production site. It reinforces Bühler’s commitment to ambitious targets that will help to mitigate climate change and build a more sustainable food system.” 

Yellow mealworms — which have been recognized as safe for human consumption by the European Commission — provide a complete protein source with all essential amino acids, vitamins and minerals, according to Divaks. At the same time, the company added, commercial insect farming is considered to have a low environmental footprint, requiring minimal water, energy and land resources. It also supports circular food systems, with insect bioconversion potentially allowing for around a third of the EU’s annual food waste to be safely upcycled, the company said.

“Edible insects have a key role to play as we move toward a more resilient and sustainable food system,” Lipnickas said. “Our new facility will help food brands tap into this fast-growing, high-potential sector with high-quality protein ingredients for premium food products.”
