About Stronga.
Stronga is a family-owned international business dedicated to delivering world-class continuous drying systems.
Since launching the FlowDrya in 2012, we have grown into a global leader in biomass, digestate and SRF drying systems known for durable, energy-efficient designs that maximise value from wet by-products and feedstocks.
FlowDrya equipment has proven its reliability in long-running installations such as the Keisby Estate AD plant, where it has operated for over 70,000 hours drying digestate fibre — and major biomass producers like Eco-Power Wood Fuels, who increased briquette output five-fold with FlowDrya. Combining strong engineering heritage with a committed, long-serving team, FlowDrya continues to set the industry standard for high-throughput drying in bioenergy, waste-to-fuel and circular-economy applications.
Global Leadership in Drying Solutions Since 2012
Since 2012, Stronga has built a globally-recognised reputation for drying wet materials with unmatched efficiency, reliability and simplicity.
With FlowDrya systems operating across the globe, from Europe and North America to Asia and Australasia, Stronga has gained extensive real-world experience in drying biomass, digestate, woodchip, SRF, waste plastics, packaging waste and other challenging materials. Over this period, the FlowDrya design has evolved to meet the rising demand for low-energy drying solutions. The fundamentals of the machine have, however, remained unchanged: the FlowDrya is still robust, reliable, uncomplicated and easy to operate, qualities that make it the world's leading dryer for biomass, digestate and a wide range of organic and recycled materials. This long-term development — combined with proven international performance — positions Stronga as a trusted global partner in advanced drying systems.
