GPS Renewables to Manufacture Paddle Agitators in India

08 Sep 2025 CW Team

Conventional agitators in use today consume higher power and struggle with substrates such as paddy straw and Napier grass, leading to crust formation, poor mixing, and sediment deposits. The Varibull Paddle Agitator addresses these issues with higher efficiency, better handling of fibrous material, and significantly lower energy use. GPS also plans to explore exports as part of its goal to scale advanced biogas technologies.

Rajesh Ayyappasur, Director – Business Development & Partnerships at GPS Renewables, said, “At GPS Renewables, our focus has always been on introducing innovative technologies that can categorically address challenges in biogas production in India. This partnership with Biogastechnik Süd Germany marks a significant milestone for us as we enter into a new product category with the introduction of paddle agitators.”

Mainak Chakraborty, CEO and Co-founder, GPS Renewables, added, “Many Indian CBG plants that rely on conventional agitators face crusting, sediment build-up, uneven mixing, higher power consumption, and frequent breakdowns. Proven paddle agitators like Varibull from BGTS are purpose-built for tough substrates and will enable efficient mixing, lower energy use, and reliable, low-maintenance operation for CBG developers.”

Gregor Maier, CEO of Biogastechnik Süd, said, “India is one of the most important growth markets for bioenergy, and we are proud to partner with GPS Renewables, whose strong execution capabilities and deep sector understanding make them the ideal partner for localising our solutions.”

Through this partnership, GPS Renewables will integrate BGTS’s agitator technology within its turnkey plant solutions and OptiMaxx equipment portfolio, offering Indian CBG developers a proven, future-ready solution.

GPS Renewables, a full-stack biofuels firm, and its subsidiary Proweps have partnered with Germany-based Biogastechnik Süd GmbH (BGTS) to introduce Advanced Paddle Agitators (mixers) under the Varibull brand in India. The agitators, to be manufactured at GPS Renewables’ Bengaluru facility, will improve operational efficiency and reduce costs for Indian compressed biogas (CBG) developers.
