Innovation

Industry Problem

Sweden imports much of its seafood, while land-based aquaculture can have high energy use, nutrient waste and capital costs.

R&D Focus

Land-based recirculating aquaculture and industrial symbiosis.

Innovative Solution

Co-locates rainbow-trout farms with process industries to reuse surplus heat, oxygen, water and nutrient streams in a circular production system.

Solution Effectiveness

The company reports about 20% higher aquaculture efficiency. Its permitted Alby project is designed for 6,000 tonnes of rainbow trout annually, targeted for operation in 2027.

About

Big Akwa is a food-tech innovation start-up that economically and environmentally revolutionizes land-based aquaculture by introducing industrial symbiosis between the aquaculture and the process industry. Our solution introduces an efficient circular approach to the fish production based on industrial symbiosis. Low temperature waste heat from the plant is used to warm up fish farm water, ensuring faster fish growth and lower energy usage. The dirty water from fish farm is converted into a resource for the industry too. The usage of new technology, sharing resources and infrastructure presents a novel opportunity to improve the environmental footprint of fishfarm and with decreased capital investments reduces production costs up to 20%. Sustainable fish can be farmed in a closed loop each year, with no nutrients released in nature.
