All food production has an impact on nature, whether we speak about the area that a production occupy or the discharge from a facility. The level of impact depends on the location, the farming area, the volume of production, the system design and the discharged amount and the content.
All the plants are built in industry-regulated areas. This means that the areas have been selected and approved by the authorities for this specific food production industry. Many of the fish farms are placed in already established industrial areas. It is the local government that decides what can be built and the impact on nature is always considered before any approvals are given. Prior to the execution of a project, the permit is either approved for a limited period or on a permanent basis.
To minimize the impact on nature, we have introduced the zero water concept (ZWC) in our recirculation aquaculture systems (RAS). This technology brings down the nitrate and phosphorous levels and reduces the water consumption by 99%. The technology also makes it considerably easier to retain all sludge and treat the effluent water to meet the consent levels permitted. The accumulated sludge can be used for soil improvement and fertilizing or for biogas and biodiesel.
Our teams of engineers and biologists are always ready to support customers in identifying the most efficient treatment technologies to meet the requirements for a sustainable production.
