EcoDurable is a Free State-based cleantech venture that transforms low-value waste streams specifically discarded tyres and waste glass into high-performance, eco-friendly paving blocks and pothole repair materials. The solution addresses the growing environmental challenge of non-biodegradable waste accumulation while simultaneously providing affordable and durable construction alternatives for households and small-scale infrastructure. By combining crumb rubber from end-of-life tyres with recycled glass powder and an eco-friendly binder, EcoDurable produces weather-resistant, flexible, and long-lasting paving solutions suitable for driveways, walkways, and rural access paths. This approach significantly reduces reliance on traditional cement-based materials, thereby lowering carbon emissions associated with construction. The innovation is designed with a strong focus on the circular economy, enabling local waste collection, processing, and manufacturing within communities. EcoDurable aims to create inclusive economic opportunities by engaging youth, women, and informal waste collectors in the value chain, contributing to job creation and skills development in green manufacturing. Currently at a prototype and pilot-ready stage, EcoDurable is preparing for real-world deployment in Free State communities, with plans to scale across South Africa. The venture aligns with national priorities on waste reduction, climate action, and sustainable infrastructure, offering a practical and scalable solution for a cleaner, more resource-efficient future.

Basadi E-Waste is a South African recycling company that focuses on the responsible management of electronic waste (e-waste). It collects, dismantles, and processes discarded electronic devices such as computers, TVs, and office equipment, ensuring they are safely recycled, refurbished, or remarketed.
The company aims to reduce environmental harm by preventing toxic materials from ending up in landfills, while also recovering valuable materials like metals and plastics for reuse in manufacturing.
In addition, Basadi E-Waste supports a circular economy by turning waste into new products and creating job opportunities, particularly contributing to sustainable development and environmental protection in South Africa. Basadi E-Waste extends its recycling operations beyond basic dismantling by focusing on the beneficiation of e-waste plastics into valuable raw materials. After electronic devices are manually dismantled, plastic components are carefully sorted by type and quality, cleaned, and processed through shredding and pelletizing. This process converts the plastic into reusable pellets that can be sold as secondary raw materials to manufacturers for the production of new plastic products.
Through this approach, Basadi E-Waste diverts significant volumes of plastic from landfills while supporting a circular economy—turning waste into input materials for industries such as packaging, construction, and manufacturing.
In addition to producing plastic pellets, the process also generates by-products such as mixed plastic blends for lower-grade applications, as well as recovered metals and components extracted during dismantling. These by-products create additional revenue streams and ensure that almost every part of the e-waste is utilized efficiently, minimizing waste and maximizing value recovery

eSwitch AI is a hardware-agnostic Virtual Power Plant (VPP) and Microgrid OS designed specifically for enterprise commercial EV logistics fleets. The transition to zero-emission transport is currently bottlenecked by constrained municipal grids and crippling Time-of-Use (TOU) peak tariffs.
Our software solves this by transforming passive logistics depots into active, intelligent energy hubs. Utilizing unified API frameworks (such as Enode), our platform ingests real-time vehicle telemetry (State-of-Charge, dispatch schedules) alongside localized depot infrastructure data (solar PV yield and Battery Energy Storage levels).
Our proprietary AI engine acts as an automated orchestration layer. It dynamically throttles DC fast chargers to prevent site overloads, autonomously pauses non-urgent charging during peak tariff windows, and actively prioritizes "free" on-site solar energy. By removing the need for massive, expensive physical grid upgrades, eSwitch AI guarantees fleet charging uptime during load-shedding while radically reducing the blended operational cost per kWh.

Acid Mine Drainage (AMD) is one of the most pressing environmental challenges in the mining sector, characterised by acidic water contaminated with dissolved metals. Our solution deploys a high-efficiency Jetloop Reactor system to treat AMD using an integrated, circular approach. A key advantage of our system is its ability to utilise industrial waste, particularly fly ash from coal-fired power stations, as a reagent. This reduces chemical costs while addressing another major waste stream, positioning the solution within a circular economy framework. The treatment process produces two valuable outputs: up to 70% recovered water suitable for reuse in industrial applications, and a mineral-rich sludge that can be repurposed into construction materials such as bricks, kerbs, and backfill. This eliminates the need for costly sludge disposal while creating an additional revenue stream. The Jetloop Reactor system is compact, scalable, and energy-efficient, making it suitable for deployment across mining operations, power stations, and industrial sites. By combining rapid treatment kinetics, resource recovery, and waste valorisation, our solution delivers a cost-effective and sustainable pathway for AMD management."

The Thermal Battery Kettle is a low-power kettle designed to fundamentally reduce peak electricity demand associated with water heating. Conventional kettles draw 1.8–3kW and are among the largest contributors to residential peak load, particularly during morning and evening demand spikes. It is estimated that simultaneous kettle usage in homes can contribute materially (300 to 400MW) to grid spikes during peak times, contributing to grid instability and load shedding in South Africa.
The Thermal Battery Kettle addresses this by decoupling energy input from energy use. A low-power (200W) heating element gradually charges a solid-state thermal storage core, allowing energy to be stored over time rather than drawn instantaneously. When required, the stored thermal energy is released to boil water with zero electrical draw at the point of use.

This approach enables:
• Peak load reduction and improved grid stability
• Compatibility with small inverters and solar systems without costly upgrades
• A pathway to fully off-grid operation, including bundled solar-powered variants
The product is designed to be safe, unpressurized, and mechanically simple, with no moving parts beyond a user-controlled interface.
The target market includes grid-constrained households, solar users, and off-grid communities, with a clear pathway to scale across South Africa and other emerging markets facing similar energy challenges.

Fleetainable is a carbon-intelligence management platform that helps organizations measure, manage, and reduce the environmental impact of their operations. By connecting fuel data, vehicle movement, and location information, the platform automatically calculates energy use, carbon emissions, air pollutants, and the true environmental cost of fleet operations. Instead of relying on rough estimates, Fleetainable, which is a SaaS tool, gives a clear, real-time picture of Scope 1 carbon emissions, where fuel is being used or wasted, and how operations impact the environment. This helps organizations reduce fuel losses, improve efficiency, and lower emissions at the same time. The platform also generates simple, audit-ready sustainability reports, making it easier for companies to meet ESG and regulatory requirements without manual work. Designed for industries with significant emissions propensity, such as mining, logistics, and power stations – Fleetainable turns everyday fleet data into practical insights that save money and support more responsible operations.
