Industrial innovation and circularity in Trøndelag
Next to Salmar's modern smolt facility at Malm, we are now developing Malm Biogas. This will be one of Norway's most advanced biogas plants, tailored to handle large quantities of organic waste from both agriculture and aquaculture in the region.
A strategic resource node
The plant is designed to process 150,000 tonnes of biomass annually. Through close collaboration with local stakeholders, we ensure a robust, circular value chain where nothing goes to waste.
We accept:
- Aquaculture Fish sludge and fish silage directly from Salmar and other operators in the aquaculture industry.
- Agriculture Manure from nearby farms, which is converted into valuable energy before the nutrients are returned to the soil.
Future products for transport and industry
By harnessing the market's best technologies, including Antec's proprietary solutions, we manufacture high-value products:
- Liquefied biogas (LBG): A green, zero-emission fuel alternative for lorries and ships, contributing to a more sustainable transport sector.
- Precision fertiliser: We produce a nutrient-rich bio-fertiliser where phosphorus and nitrogen are separated. This enables local farmers to fertilise more precisely, improve crop yields and cut the need for synthetic fertilisers.
- Green CO₂ In the next phase, we are planning the capture of biogenic CO₂ for use in the food industry, which closes the loop even further.
Local economic impacts
Malm Biogass is to be a key player for sustainable energy in the region. The project will generate significant activity in the municipality:
- 5 to 7 direct jobs related to operations and administration.
- 6–8 indirect jobs within logistics, transport and maintenance.
Status and progress
The project is now in FEED phase (Front-End Engineering Design). We are working closely with all relevant stakeholders and authorities ahead of the final investment decision (FID).
Planned start: Q3 2027
