300 tonnes of straw, manure, maize and sugar beet per day for the biogas plant
Lars Langsgaard Nielsen is a fifth-generation farmer and continues to run the traditional family business on the island of Funen in Denmark. His farm is located in Otterup in northern Funen, where he runs a modern pig farm. Around 18,000 pigs are produced there every year.
Since the early 2010s, the agricultural business has been supplemented by the Lykkeslund Bioenergi biogas plant. It was built to convert organic waste from agriculture into energy and contribute to a sustainable energy supply.
In 2024, the plant underwent a technical upgrade: a Tietjen BMS biomass shredder, new dosing and pumping technology, and a magnetic separator were installed by system integrator Lobe ApS.
This modernisation improves the processing and feeding of biomass to the biogas plant, thereby optimising the entire fermentation process.
Biomass Shredder BMS – Manure, Straw and Sugar Beet for Biogas Production
Why was the BMS biomass shredder installed?
“And if I chose this system, it’s also because I think it’s quite important to grind all the material that comes in. The more it is grinded before it enters the fermenters, the faster we get the gas out.” Lars Langsgaard Nielsen. (Translation from Danish)
During impact grinding in the BMS biomass shredder, the biomass is intensively broken down mechanically: trapped air is removed and the lignin structure in the plant material is specifically broken down. This special pre-treatment means that straw is broken down much more quickly. As a result, gas production also starts much earlier, which increases the overall efficiency of the plant and enables continuous energy production.
Substrates for the production of 7 million cubic metres of biogas
Lykkeslund Bioenergi produces more than 7 million cubic metres of biogas annually, which is fed into the public gas grid after purification and processing. To achieve this volume, up to 121,000 tonnes of biomass are processed each year. At Lykkeslund Bioenergi, this biomass is composed as follows:
- Manure from pig farming
- Cow manure from surrounding farms
- Wet straw that is unsuitable for combustion
- Sugar beet, maize and grass
How satisfied is Lars Langsgaard Nielsen with the BMS biomass shredder?
“The BMS we have installed has a large capacity, so it can process a lot, and it doesn’t really matter what goes in, it just gets grinded. I would recommend the Biomass Shredder BMS to other biogas plants.” Lars Langsgaard Nielsen. (Translation from Danish)
