Pyrolysis plants as the key to climate-neutral supply – experiences from Lemvig Vand A/S

Water & Energy | Hal MEnglish

Lemvig Vand has just commissioned a new pyrolysis plant. On stage, the company will provide insight into the journey they have been through – from the initial considerations to the final decision and construction of the facility. The presentation delves into the central reflections that formed the basis of the investment: Which factors and expectations were decisive? And what are the perspectives now – both operationally and strategically in a forward-looking climate accounting context?

Sewage sludge is a significant source of CO₂ emissions, and with the goal of climate neutrality in the utility sector by 2030, there is a need for major technological shifts. Lemvig Vand has taken a big step in this direction with the commissioning of a new pyrolysis plant – and in this presentation, they share experiences from the entire process: from the first strategic considerations to the implementation and operation of the facility.

Pyrolysis is expected to reduce the utility’s overall CO₂ footprint, while the technology also opens new opportunities for environmental protection, including the breakdown of PFAS, pharmaceutical residues, and microplastics. In addition, important nutrients such as phosphorus are preserved, which can be used in fertilizers. Thus, pyrolysis represents not only a technical solution – but also a strategic choice at a time when green transition and resource recycling are more relevant than ever.
