Ochis produces the world's first eyewear made from coffee and plant-based biopolymers. It collects used coffee grounds from local cafes and transforms them, together with flax shives and natural oils, into a proprietary, patented biopolymer called BIOCOFEX, produced fully in-house for quality control. The finished eyewear - frames and lenses - is biobased, water-resistant, durable, carries a subtle coffee aroma, and is designed to last for years before returning to the earth. Unlike many 'eco' eyewear brands that still rely on plastics, Ochis controls the entire cycle, from collecting grounds to crafting frames. It sells through a dual-channel model combining B2B partnerships with optical retailers and concept stores and direct-to-consumer online sales. Each frame saves around half its water footprint and cuts CO2 by roughly 80% compared with conventional cellulose-acetate eyewear. Ochis has sold over 3,000 pairs across 48 countries, works with retail partners, and has been featured by BBC, Forbes, and Vogue.

Java General Trading (Pty) Ltd purification system is designed to deliver safe, reliable and sustainable drinking water in rural Namakwa and surrounding areas. At its core, the system uses multi-stage purification process that combines sediment, carbon, and membrane technology to remove contaminants such as sediments, bacteria, viruses, heavy metals, and chemical pollutants. This layered approach ensures high water quality while maintaining consistent performance even when input water conditions vary. A key feature is a solar-powered water purification system with smart water monitoring, making it suitable for off-grid or energy- scarce settings. Smart monitoring sensors track water quality and system performance, reducing downtime.
The modular design allows for easy scaling according to demand, whether serving a simple household, school, or an entire community.
Components are designed for durability and ease of maintenance, minimizing operational costs and technical complexity.
Sustainability is central to design. The system reduces reliance on single-use plastic bottles and minimize wastewater generation, compared to conventional purification methods.
Overall, the solution provides an efficient, adaptable, environmentally responsible approach to water purification, helping to improve public health, support community resilience, and contribute to long-term water security

A research team at the University of Johannesburg is developing a Pure Electric Vehicle (PEV) designed to reduce environmental pollution from conventional agricultural machinery. Led by Prof. Nnamdi Nwulu and Mr. Musole I. Muheme, the initiative addresses the need for cleaner, energy-efficient alternatives in the agricultural sector. The PEV integrates advanced control technologies, including a loop controller that minimizes voltage drop and optimizes power use. With remote control functionality to support precision farming, the vehicle is tailored to the needs of small-scale agricultural operations. The solution offers a sustainable, low-emission alternative that contributes to both environmental conservation and improved farming efficiency.

Cabinet EDE International is an engineering and consulting company founded in 2001 and headquartered in Dakar, Senegal. The company operates across environmental health, water and sanitation, waste management and related infrastructure sectors, providing technical studies, project design and implementation support for public and private sector. Within its portfolio of solutions, Cabinet EDE International has developed a household-scale biogas system focused on the treatment and valorization of organic waste. The system converts organic waste from domestic and market environments into biogas for cooking and mineral-rich biofertilizer for agricultural use, addressing challenges related to organic pollution, waste management and access to biomass-based energy. The biogas unit is designed to operate with both solid and liquid inputs and uses mold-cast construction to ensure gas and water sealing. Unlike conventional fixed-dome digesters, the system does not require specialized technical skills to install, is easy to maintain and is designed for long-term operation, with an estimated lifespan exceeding 30 years. The technology has been piloted in high-organic-waste settings, including Senegal’s central fish market. Through this solution, Cabinet EDE International applies its engineering and environmental expertise to decentralized waste-to-energy applications, supporting circular economy approaches in household and community-scale contexts.

Harcy works on circular economy-focused construction materials derived from textile waste. The company addresses waste streams from the textile industry while supplying material solutions for the building sector. Harcy’s primary product, Harcy Polyester Wool, is a thermal and acoustic insulation material manufactured from post-consumer and post-industrial polyester waste. Each square meter of insulation repurposes approximately 2 kg of polyester, contributing to waste reduction and material circularity. The product is designed for use in residential and commercial buildings. The insulation features a fibrous, water-repellent structure that supports moisture control and low vapor diffusion, while remaining fire-resistant, durable and free from harmful chemicals. It is dust-free during installation, does not disintegrate, and is designed to avoid skin irritation, supporting cleaner application processes. At end of life, the material is recyclable, enabling reintegration into production cycles. Harcy operates at the intersection of textile waste valorization and sustainable construction materials.
