GPS Renewables Partners with Germany’s Biogastechnik Süd to Manufacture Advanced Paddle Agitators in India

GPS Renewables, a leading full-stack biofuels firm, has announced an exclusive partnership between its subsidiary Proweps and Germany-based Biogastechnik Süd GmbH (BGTS) to introduce Varibull Advanced Paddle Agitators in India. The agitators, globally recognized for efficiency and durability, will now be manufactured at GPS Renewables’ Bengaluru facility.

The collaboration aims to improve operational efficiency of biogas and Compressed Biogas (CBG) plants in India, while offering cost advantages over conventional agitators currently in use. Unlike traditional mixers—which often struggle with high-fibre substrates like paddy straw and Napier grass, leading to crust formation, sedimentation, and higher power consumption—the Varibull Paddle Agitator is designed to deliver superior mixing, lower energy use, and long-term reliability.

Speaking on the development, Rajesh Ayyappasur, Director – Business Development & Partnerships, GPS Renewables, said:
“Our focus has always been on introducing innovative technologies that can address challenges in biogas production. This partnership marks a significant milestone as we enter into a new product category with paddle agitators, leveraging Biogastechnik Süd’s global expertise.”

Mainak Chakraborty, CEO & Co-founder, GPS Renewables, added:
“Many Indian CBG plants face crusting, sediment build-up, and frequent breakdowns due to conventional agitators. Proven paddle agitators like Varibull are purpose-built for tough substrates and will enable efficient mixing, lower energy consumption, and reliable operations.”

From the German side, Gregor Maier, CEO of Biogastechnik Süd, emphasized India’s importance as a bioenergy growth market:
“Our mission is to deliver reliable and efficient technologies that add long-term value to biogas operators. Partnering with GPS Renewables ensures effective localization of our solutions for Indian developers.”

Robert Ohneberg, International Sales Manager, BGTS, noted:
“The Varibull Paddle Agitator has become one of the world’s best-selling agitators due to its robustness and low-maintenance design. Through this partnership, we can help Indian CBG plants achieve higher process stability and reduced lifecycle costs.”

The agitators will be integrated into GPS Renewables’ turnkey plant solutions and its OptiMaxx equipment portfolio, with plans to also explore export opportunities from India.

Taking a holy dip in the Ganga, offering prayers to Maa Ganga, and visiting Baba Vishwanath is a centuries-old tradition in Kashi. Now, devotees will soon be able to do all this with greater ease, thanks to a unique initiative of the Yogi government — hexagonal-shaped floating jetties on the Ganga.

These special jetties will come with changing rooms and a small place of worship, making it convenient for devotees to bathe, change clothes, and perform rituals without having to move around. Boats will also be able to dock directly at these platforms.

Officials said the hexagonal design has been chosen so that the natural flow of the river is not disturbed. Each jetty will have a shed-covered worship space, four changing rooms, double railings for safety, and a double-layer HDPE pontoon to keep it steady in water.

“After successfully trying out floating changing rooms at eight ghats, we are now setting up four advanced floating jetties with both worship and changing facilities,” said Smart City Chief General Manager Amarendra Tiwari.

Work on the project will begin once the water level of the Ganga comes down. Each jetty, spread across 73 square meters, will cost about ₹1.87 crore.

Officials say these floating jetties will be a perfect example of how modern technology and tradition can come together — ensuring convenience for devotees while keeping the Ganga clean and uninterrupted.
