Sustainability is important to our company.
At Assentoft Aqua we believe economic- and environmental sustainability goes hand in hand, and this is what forms the basis for a successful landbased RAS fish farm – now, and for the future.
Therefore we do already in the idea, design, and planning stages, consider various ways to built SUSTAINABILITY into the RAS projects we’re involved with.
Below are some of the parameters we consider essential to achieve success with a landbased RAS fish farm – including some important sustainability factors to consider as well.
- Location – farmed close to the market it is intended for (to minimize transportation).
- Site – suitable location and advantageous site parameters – must facilitate an economical landbased RAS production.
- Production input – farmed in a location with access to sustainable sources of water, energy, and feed.
- Production plan based on relevant growth models and RAS experience figures.
- Farmed in buildings and systems leaving a minimal land footprint.
- Design and choice of equipment components with a focus on durability and low energy consumption.
- Availability and hiring of dedicated staff and experienced management team.
RAS Technology & Production
- Design and dimension of individual components (and plant sections) for optimal growth and minimal stress for the fish.
- Use of efficient and proven recirculating water treatment processes (for maintaining an optimal water quality).
- Feeding with a quality RAS feed and a focus on minimizing any feed waste.
- Applying effluent water treatment technology and use of bioremediation (in cooperation with partners).

Sustainability Partner – Advanced Substrate Technologies
One of our sustainability partners is Advanced Substrate Technologies (AST).
AST is a technology company which designs, constructs, projects and installs turnkey process plants.
By using partially degassed biomass, it is possible to dramatically increase the utilization of the energy potential of biogas plants, produce substrates for fungal production, bedding for poultry and cattle, and fertilizers.
Through the combination of expert competencies and a targeted investment in an experimental plant, we have built up such extensive experience that the technology is now ready for industrial scale operation – and the first major projects are in the pipeline.
