Arjun increases its stake in the Danish biogas platform Bigadan

Arjun Infrastructure Partners is pleased to announce it has increased its investment in Bigadan, a Danish biogas platform, supporting the company’s next phase of growth and development. This acquisition is the second investment of Arjun’s latest fund, the Infrastructure Alliance Europe 3 (IAE-3) fund.

Bigadan is a leading Danish renewable energy platform transforming organic waste including manure, food industry by-products and industrial organic waste products into biogas for renewable energy and fertilisers. With over 40 years of operational experience, the company owns nine operational biogas facilities producing around 1.3 TWh of renewable energy annually, with plans to increase output to over 2 TWh by 2027. Operating under long-term feed-in tariffs, Bigadan plays a central role in Denmark’s circular bioeconomy while also providing engineering and operational expertise to third-party partners.

Under Arjun’s majority ownership, Bigadan will be well positioned for its next phase of growth. The company plans to expand its platform through the development of carbon capture facilities and the conversion of two additional plants from combined heat and power (CHP) generation to grid injection. These initiatives will further strengthen Bigadan’s contribution to Denmark’s renewable gas supply, energy security, reduce emissions and support national decarbonisation objectives.

Additional avenues for expansion being considered are increasing biomethane output for use in transport and industry, liquefying biogenic CO₂ for Carbon Capture Usage & Storage (CCUS), and replicating its model in international markets.

The acquisition underscores Arjun’s long-term commitment to the European energy transition and its strategy of investing in real infrastructure - essential, sustainable infrastructure that delivers reliable, inflation-linked returns for investors while supporting the shift to a low-carbon economy.

Surinder Toor, Managing Partner at Arjun Infrastructure Partners, commented: “This investment marks an important milestone in Arjun’s energy transition strategy, highlighting our strong conviction in the business. Bigadan’s integrated model represents significant growth and diversification opportunities, with exceptional positioning to support Europe’s decarbonisation strategy, backed by supportive Danish and European policy. We look forward to working even more closely with Bigadan’s leadership to advance the transition to a low-carbon economy and continue delivering on Arjun’s commitment to investing in real, essential infrastructure.”

Henrik Laursen, CEO at Bigadan, added: “We are pleased to have Arjun support us in our aspiration for the next phase of our growth strategy. Together, we work to implement a range of new initiatives and expansion projects to capture the opportunities in the biomethane, carbon capture, and energy transition sectors - unlocking the company’s significant growth potential."
