AquaOpti

Problem statement

Utilizing aquaculture waste streams for the production of economically viable products

Executive summary

AquaOpti – using bioremediation as a component of integrated multitrophic aquaculture. The underlying philosophy of theproject is to exploit an aquaculture waste stream for the production of an economically viable product, and thus to contribute to the sustainability and economic viability of Irish aquaculture

Value chain description

The emphasis of the project is method development, with a focus on commercial applications. The proposed project will explore how: 1. Lemnaceae (duckweeds) can improve water quality as part of Integrated Multitrophic Aquaculture (IMTA) 2. Enhance fish production and quality 3. Produce a high-quality feed, protein rich feed, thus demonstrating the benefits of circular economy approach

Market deployment considerations

The global duckweed protein market is forecast to reach a market valuation of US$ 87.7 million in 2023, and further register a growth rate of 8.9% CAGR over the forecast period from 2023 to 2033

Environmental considerations

CO2 sequestration, climate change mitigation
