Arciplug, a pioneering Finnish engineering company, is redefining the biogas landscape with its patented “PLUG FLOW” digester technology. Backed by more than 15 years of expertise and over 30 installations across the globe, Arciplug converts even the most challenging organic and mixed waste, from agricultural straw to municipal solid waste, into renewable biogas and biomethane. Remarkably, the process requires no added water and minimal energy input, setting a new benchmark for efficiency and sustainability.
With factory-prefabricated, turnkey systems, Arciplug ensures swift installation, uniform performance, and effortless scalability worldwide. Headquartered in Jyväskylä, Finland, the company blends engineering precision with a powerful sustainability vision: turning waste into lasting value.
In an exclusive conversation with The Interview World at the Renewable Energy India Expo 2025, Tejas Chauhan, Project Manager (Asia) at Arciplug, shed light on the company’s cutting-edge biogas technologies. He outlined what makes their system uniquely effective, discussed its role in tackling stubble burning in Northern India, and shared insights into Arciplug’s growing production capacity in India. The following are the key takeaways from this enlightening exchange.
Q: Could you elaborate on the technologies and solutions Arciplug provides for the biogas industry?
A: Arciplug, headquartered in Jyväskylä, Finland, stands at the forefront of biogas innovation with its patented Plug Flow Reactor technology. The company operates this advanced system to generate biogas from virtually any challenging feedstock, from paddy and wheat straw to press mud from the sugar industry, cow dung, corn straw, maize, Napier grass, and other organic or biodegradable wastes.
Unlike conventional systems, Arciplug’s technology delivers superior efficiency and performance, transforming diverse waste streams into clean energy with remarkable consistency. In essence, if it’s organic, Arciplug can turn it into biogas efficiently, sustainably, and at scale.
Q: What makes this technology stand out from other solutions in the market?
A: The true breakthrough of Arciplug’s technology lies in one game-changing fact, it requires no additional water. Conventional biogas systems consume enormous amounts of water, an irony in a world where 70% of the planet is covered by water, yet so little is fit to drink. Arciplug turns that challenge into an advantage.
By eliminating water dependency, the company not only conserves a precious resource but also enhances system efficiency and sustainability. In doing so, Arciplug simultaneously produces renewable biogas and drives a circular economy, empowering farmers and communities across the globe to turn waste into clean energy without draining vital water reserves.
Q: Stubble burning remains a major environmental challenge in Northern India. Has your technology proven effective in addressing this issue?
A: Until recently, farmers had no alternative but to burn paddy and wheat straw, a practice that caused severe air pollution across Punjab, Haryana, and even the Delhi-NCR region. The lack of viable solutions for converting crop residue into energy left them with little choice, and no economic return.
Arciplug’s revolutionary Plug Flow technology has changed that narrative. Today, farmers can transform what was once waste into wealth, earning revenue by supplying straw for biogas production. This shift not only reduces pollution but also creates new income streams for both farmers and plant operators, who profit from the sale of clean biogas.
Moreover, the process yields a valuable byproduct, organic digestate, which serves as a natural fertilizer. At a time when organic farming is rapidly gaining global traction, this fertilizer provides a sustainable alternative to chemical inputs. In essence, Arciplug’s innovation powers a complete circular economy, converting agricultural waste into renewable energy and nutrient-rich organic fertilizer, while driving environmental and economic resilience across rural communities.
Q: What is your current production capacity in India, and how do you plan to further expand it?
A: Arciplug has launched its first plant in India, located in Ambala, Haryana, marking a significant milestone in the country’s clean energy journey. The facility processes 100 tons of paddy straw per day and produces 15 tons of bio-CNG daily, a powerful example of how agricultural residue can be transformed into renewable energy.
The plant is currently in the commissioning phase, having already achieved 50% operational capacity, with full-scale commissioning underway. Though the process is gradual, the progress reflects Arciplug’s commitment to precision and performance.
Building on this success, the company is now advancing over 15 additional projects across India, focusing on energy crops, agricultural residues, and biowastes. Together, these initiatives will not only accelerate India’s biogas production but also strengthen the circular economy, turning waste into opportunity while driving cleaner, more sustainable growth for the nation.
