In a significant step towards enhancing sustainable agricultural practices in South Africa, the Technology Innovation Agency (TIA), in collaboration with Fine Bubble Technologies, has launched a nanobubble aquaponics pilot plant at De Grendel School of Skills in Cape Town.
This pioneering project merges fish farming with hydroponics, aiming to enhance water and nutrient efficiency while reducing dependency on chemical fertilisers. It promises to drive forward sustainable agricultural practices, addressing critical issues related to water and nutrient management.
Fine Bubble Technologies, renowned for their advancements in natural water treatment, have introduced patented nanobubble generators that are revolutionizing aquaponics.
Their technology, which creates a staggering 222 million bubbles per millilitre, is a breakthrough in the water treatment industry. These generators enhance water aeration, which is crucial for the health and productivity of both fish and plants. The applications of this technology span across agriculture, aquaculture, medical cleaning, and water purification.
The development of this technology has been co-funded by the department of science and innovation (DSI) through the Agriculture Bioeconomy Innovation Partnership Programme (ABIPP).
ABIPP, an initiative of the DSI, supports agricultural bioeconomy projects by coordinating and funding multi-institutional and co-funded initiatives that contribute to increased productivity, food security, and rural economic development.
The new pilot plant builds on the success of a phase I project, also funded by DSI, which demonstrated a 50% increase in productivity in aquaculture and hydroponics due to the use of nanobubble technology. This advancement addresses common challenges such as pathogen presence and oxygen deficiency, which have traditionally impeded productivity in these systems.

Affordable and sustainable aquaculture solutions
Traditional methods of oxygenation in aquaculture are often costly and inefficient, creating barriers for small-scale and subsistence farmers. The new pilot plant aims to overcome these challenges on a larger scale. By demonstrating the potential of nanobubble-enhanced aquaponics systems, the project seeks to create a replicable and sustainable business model.
Located at De Grendel School of Skills, the pilot plant not only contributes to the school’s food security but also provides direct benefits to the local community. The produce from the plant will be used for school meals, with any surplus sold to local residents.
This initiative supports both food security and economic sustainability through the diffusion of innovative technology.
Sibusiso Manana, head of agriculture at TIA, praised the project, stating, “The installation at De Grendel School of Skills is a testament to the power of bio-innovation in driving economic growth, improving health outcomes, and fostering sustainable communities.
“TIA is committed to supporting innovations that align with the DSI Bioeconomy strategy, and Fine Bubble Technologies exemplifies how innovative solutions can meet the multifaceted goals of this strategy.”
The aquaponics plant has been well received by the school’s principal and staff who have noted the enthusiasm of the learners for the new system. District office officials from the Western Cape department of education were also in attendance, expressing interest in expanding the initiative to other schools and communities.
