The global biogas plant market is hosting long-established Europe-specific engineering leaders such as EnviTec Biogas and PlanET Biogas that offer turnkey anaerobic digestion and upgrading solutions. Meanwhile, the integrated energy firms such as ENGIE and Wärtsilä leverage global scale and long-term offtakes, whereas the specialist technology providers such as WELTEC BIOPOWER and Naskeo focus on modular and efficient designs. In this context, in May 2025, Nordic energy company Gasum acquired full ownership of NSR Biogas AB and the remaining shares of Liquidgas Biofuels Genesis AB in Helsingborg, Sweden, by consolidating the entire biogas production and upgrading chain at the site. It also mentioned that the plant processes 160,000 tons of household, industrial waste, and manure, producing up to 80 GWh of upgraded biogas annually, which is supplied to the market.
