Research project Circularity by combining aquaculture, entemoculture and hydroponics

General introduction

To what extent can aquaculture linked to insect farming and hydroponics be realized as an interesting circular system for food production? That is the exploratory research question in the AEP-PULSE project. The aim is to maximize the reuse of waste streams to reduce the use of (expensive) raw materials and produce less waste. Hydroponics is plant cultivation using nutrient-rich water instead of soil. Insects provide frass (insect manure and residues from the cultivation substrate), among others.

Research approach

ILVO is researching bioactive substances in insect farming waste products, such as molted remains and frass, and testing their effect on shrimp. Afterward, a bio-screening is done to identify the active components. Together with BGC, a preliminary study is conducted into the use of residual heat from biogas within the system. Finally, a demonstration setup is developed to cultivate gray shrimp and seaweed using insect-based feed and utilizing residual heat from the biogas site.

Relevance/Valorization

The goal is a more sustainable and efficient production system that reduces costs and conserves resources. The system offers a solution to high production costs and scarce resources such as water, space, and raw materials. It aims for local and circular production, with cost reduction through shared infrastructure and space savings through vertical farming. At the same time, essential resources are anchored locally: energy, nutrients, and seawater.
