Adone Facilities management has developed an integrated circular feed system that converts organic waste into sustainable animal feed and organic fertilizer. The system combines Black Soldier Fly (BSF) larvae production with duckweed cultivation, using both solid and nutrient-rich liquid waste streams to produce dual protein sources. BSF larvae provide high-quality insect protein, while duckweed offers a fast-growing plant protein alternative. These are blended into a cost-effective feed solution for poultry, aquaculture, and livestock. The modular system reduces waste, lowers feed costs, and supports local production, contributing to circular agriculture, climate resilience, and sustainable food systems in emerging markets.

CircularBuild is a construction materials marketplace focused on reducing waste and improving efficiency in the construction industry.
In South Africa, a significant amount of construction materials is lost as waste each year, despite ongoing demand from builders and contractors. CircularBuild addresses this gap by enabling contractors, suppliers, and developers to sell surplus and unused materials instead of discarding them.

The platform connects supply and demand through a combination of on-the-ground sourcing and simple digital tools, allowing materials to be captured, listed, and redistributed quickly. This helps sellers recover value from unused stock while giving buyers access to more affordable materials.
CircularBuild is currently in its early operational phase, working directly with construction sites to identify surplus materials and facilitate real transactions between users. This hands-on approach allows the company to validate market demand, build trust, and refine its model based on real-world activity.

By improving material reuse, CircularBuild contributes to reducing construction waste, lowering carbon impact, and supporting a more circular economy within the built environment.
Over time, CircularBuild aims to expand into a broader infrastructure layer that supports logistics coordination, material data insights, and sustainability reporting across the construction value chain.

GemanLee is a South African cleantech venture specialising in the recovery and refinement of high-value critical metals from end-of-life lithium-ion batteries. Operating within the waste beneficiation sector, the company collects spent lithium-ion batteries from registered recyclers across Gauteng Province, processes them through a proprietary mechanical and electrochemical recovery system, and produces battery-grade outputs including cobalt, nickel, manganese, and lithium carbonate, achieving metal purities of up to 99.66%.
The core technology combines an eco-friendly organic acid leaching system with a novel ultrasonic-assisted electrochemical recovery method. Unlike conventional pyrometallurgical approaches which are energy-intensive, CO₂-heavy, and destroy lithium in the process and standard hydrometallurgical methods that rely on hazardous inorganic acids, GemanLee process uses biodegradable reagents, operates at lower temperatures, and produces five distinct, market-ready metal outputs rather than lower-grade mixed black mass. This results in a meaningfully lower carbon footprint and reduces hazardous waste generation.

Environmental Process Solutions (EPS) has developed an advanced Hydrothermal Liquefaction (HTLF) technology that converts wet organic and biomass waste into high-quality biocrude. Unlike conventional processes, HTLF efficiently handles high-moisture feedstocks, eliminating the need for energy-intensive drying and enabling cost-effective processing of diverse waste streams. EPS addresses two critical challenges: sustainable waste management and clean energy production. By diverting waste from landfill, the technology reduces greenhouse gas emissions while unlocking value from underutilised resources. In doing so, it produces a diesel-like biocrude suitable for refining or co-processing in existing petroleum infrastructure, enabling immediate integration into current fuel supply chains. The solution is designed for modular deployment, supporting job creation, circular economy integration, and measurable environmental impact.
