What They Do
Lundsby specializes in biogas production from biomass, offering EPC (Engineering, Procurement, and Construction) turnkey solutions that convert thousands of tons of organic waste from agriculture, households, and industry into CO₂-neutral biomethane. This biomethane can be upgraded for injection into the gas grid, liquefied biogas (LBG), or energy supply (source: lundsby.com). Their services include complete plant design, construction, commissioning, and customization for scalability, including robust tanks, upgrading systems, and byproduct management, with close collaboration with customers before, during, and after construction to ensure reliability and future expansion (source: lundsby.com). Target markets are centered around Northern Europe, where they serve utilities, energy companies, and biomass producers seeking stable green energy to complement intermittent renewable energy sources like solar and wind (source: lundsby.com). As one of Denmark's largest biogas EPC developers, they stand out with 30 years of progression from small farm plants to multimillion-scale facilities, and they have been pioneers in upgrading for the gas grid, as seen with the Madsen Bioenergy facility (source: lundsby.com).
Projects & History
Among the notable completed projects is Tønder Biogas in Denmark, which is one of Europe's largest, handling 930,000 tons of biomass annually to produce over 40 million Nm³ of biomethane, achieving a production record of 127,000 m³ per day in 2025 (source: lundsby.com). Götene Biogas in Sweden for Gasum processes 400,000 tons of biomass annually for 120 GWh of LBG and reached full operation in early 2025 (source: lundsby.com). Madsen Bioenergy in Salling, Denmark, is the groundbreaking facility for upgrading to the gas grid, established in 2012 (source: lundsby.com). Current projects include the upgrading of Langaa Bioenergy in Denmark, being carried out without stopping operations (source: lundsby.com), as well as a new 133 GWh facility in Borlänge, Sweden for Gasum under an EPC contract from 2024 (source: formland.com). An additional EPC contract was signed in November 2024 for a large-scale facility in Kiuruvesi, Finland by Suomen Lantakaasu Oy (source: formland.com). Key customers include Gasum (Sweden, Götene, and Borlänge) as well as local Danish partners, with a geographical presence in Denmark, Sweden, Finland, and previously Germany (source: lundsby.com).
Recent Developments
In the past two years, Lundsby has secured significant EPC contracts, including the October 2024 agreement in Borlänge, Sweden for 133 GWh capacity with Gasum and the November 2024 project in Kiuruvesi, Finland (source: formland.com). Tønder Biogas reached a production milestone of over 5,300 m³ of biomethane per hour in 2025, and Götene Biogas was inaugurated into full operation early in 2025 (source: lundsby.com). Langaa Bioenergy upgrades are progressing without downtime (source: lundsby.com). Leadership was transferred to Carsten Nielsen, who was appointed CEO as of April 1, 2025, to drive growth and international expansion (source: lundsby.com). The company celebrated its 30th anniversary on October 31, 2025, highlighting three decades of biogas advancements (source: lundsby.com). No acquisitions, mergers, or funding rounds were reported during this period.

Lundsby offers roles in design, technology, project management, customer service, business development, technical bid management, sales, and engineering.

Hiring takes place at the headquarters in Løgstrup, Denmark, as well as at the office in Middelfart (source: formland.com). The company culture emphasizes dynamic collaboration, professional development, and pride in contributions to large-scale biogas, as seen in employee portraits and anniversary celebrations (source: lundsby.com).

Job Description
At Lundsby Renewable Solutions, we are proud to contribute to the green transition through the development and construction of biogas plants in Denmark and the rest of Europe. We know that the future is shaped by the people who choose to engage in the solutions – which is why we would like to invite bachelor students to join us for an educational internship.
Who are we looking for?
Are you looking for an internship as part of your bachelor’s degree and have a special interest in electrical, piping or commissioning? Perhaps you have a practical background as a blacksmith, electrician, mechanic or machinist and want to strengthen your professional knowledge towards more complex technology and project work? Then Lundsby is the right choice for you.
It is not a requirement, but an advantage if you have an interest in energy, process and the green transition.
Three professional tracks - strong link between theory and practice
We offer internships in three key areas where you can put your knowledge to work while gaining hands-on experience in the technical disciplines that drive our projects forward:
Commissioning
You will be close to the actual start-up of the plants. The work is primarily on-site, where you will participate in practical commissioning, instrumentation, setting up alarm thresholds, reporting systems as well as measuring gas purity and gas detector function. A commissioning phase typically lasts 3 months of high intensity, followed by a period of fine-tuning and optimization.
Electrical design and implementation
Here you will work with electrical engineering design, documentation and possibly quality assurance of electrical contracts. You may also prepare tender documents, ensure compliance with standards and follow up on site execution.
Pipe sizing and flow calculations
You’ll dive into pipe dimensioning, flow and viscosity calculations, and optimal placement of pumps and components. The work takes place both in the design phase and as quality assurance of the practical execution.
An opportunity to grow – maybe even after your internship
An internship at Lundsby is not only an opportunity to learn – it’s also an opportunity to become part of a strong professional community where we work closely with customers, suppliers and colleagues to create the best solutions. We are approximately 100 employees and still growing. An internship with us will give you a strong hand – both professionally and on your CV.
Do you want to join us?
Every great collaboration starts with a conversation.
If you’re curious, practical and ready to turn knowledge into green action, we want to hear from you. At Lundsby, we learn from each other and we look forward to welcoming committed interns to our team.
Write or call Thomas Rye Tengstedt, CHRO. You are also welcome to connect with Thomas on LinkedIn. We look forward to talking to you.
Stay tuned for the future
