ERUSUFA is a Turkish startup that developed SUF@ - a self-sufficient urban furniture system that functions as an air purification and climate resilience tool using living microalgae. It addresses urban air pollution by capturing CO₂ and volatile organic compounds (VOCs), producing oxygen through photosynthesis, and generating sustainable biomass that can be used to manufacture biodegradable components. Each SUF@ unit has the photosynthetic capacity of six adult trees. Powered entirely by solar energy and using harvested rainwater for microalgae cultivation, the unit operates independently and includes a biosensor and automation system for real-time monitoring and optimal function. It embodies circular economy principles, producing biopolymers from its own biomass, eliminating plastic intermediates, and contributing to greener, healthier urban environments. The SUF@ system is especially suited for cities with limited green space and high air pollution, offering an innovative solution that integrates ecological restoration with smart design and flexible, modular deployment.

G&D Sorption Green Development is a startup from Türkiye that has developed an electricity-free industrial cooling system transforming low-grade waste heat into chilled water for use in process cooling and air conditioning. By harnessing waste heat without external energy input, the G&D system reduces operational energy demand and eliminates the carbon footprint associated with traditional HVAC systems. Its compact and lightweight adsorber bed enables high performance even at low flow rates and moderate temperatures (50–90°C, 3–5 m³/h), extending applicability to facilities with limited waste heat outputs. The system includes AI-supported control software that adapts performance to varying operating conditions, improving efficiency and automation. Using water and silica gel as working mediums, the chiller avoids toxic or ozone-depleting refrigerants. G&D systems are suitable for diverse sectors including metallurgy, food processing, ship cooling, geothermal plants, solar facilities, and energy-intensive industries. By replacing electricity-powered cooling units, each G&D installation can reduce CO₂ emissions equivalent to over 4,000 trees annually.

Gemasan Robotics is a robotics company developing autonomous underwater systems for marine maintenance, inspection and monitoring applications. The company’s work focuses on improving the efficiency, safety and sustainability of operations in maritime and underwater infrastructure environments. Gemasan Robotics’ technology is a modular autonomous underwater robot designed to clean biofouling and pollution from the submerged surfaces of ships, reducing hydrodynamic resistance and associated fuel consumption. The system enables in-water hull maintenance without the need for dry-docking and can be operated wirelessly or via cable, depending on operational requirements. It integrates AI-based image processing and thickness measurement software to support real-time diagnostics, hull mapping and condition assessment. Beyond maritime vessel maintenance, the robot is applicable to the inspection and cleaning of underwater infrastructure such as dams, hydroelectric power plants, ports and research installations. Its modular architecture allows configuration for additional use cases, including leak detection, sediment analysis and underwater habitat mapping. The company also provides simulation tools to support operator training and deployment planning, and is developing in-house production capabilities for key components to enhance system reliability and adaptability.

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.

HER is a biomaterials company developing leather-like alternatives for textile, fashion, upholstery and interior applications. The company focuses on replacing petrochemical and animal-based materials with bio-based inputs produced through low-impact manufacturing processes. HER’s material is produced using a proprietary fermentation-based method in which cellulose is generated by yeast in water. The process yields a biodegradable biomaterial with a soft, natural leather-like texture and color. While the full biological cycle takes place over several months, production and shaping of the material can be completed within a few days, enabling scalable and flexible manufacturing, including custom-shaped bio-leather formats. The production process is designed to be waste-free, with all residues separated into three distinct by-products for further use. The resulting material is water-resistant without chemical coatings and certified to withstand mechanical stress of up to 900 Newtons, making it suitable for functional textile and surface applications. HER operates with near-zero CO₂ emissions and positions its materials within regenerative and circular value chains aimed at waste reduction and sustainable material innovation in the textile sector.

HGG ENERGY A.Ş. is a Turkish startup that has developed a cost-effective and sustainable solution for purifying and upgrading biogas into biomethane. Biogas, while offering a renewable alternative to fossil fuels, contains toxic and corrosive components that prevent its direct use. The proposed technology uses an integrated physical and biological absorption system within a single column to remove impurities and upgrade biogas to pipeline-quality biomethane. Unlike conventional methods such as water scrubbing, chemical scrubbing, and cryogenic separation, which are capital- and energy-intensive, this approach reduces investment costs by approximately 30% and offers improved operational efficiency. The compact design of the system allows for easier deployment, and the upgraded biomethane can be fed directly into natural gas pipelines, reducing the carbon footprint and fossil fuel dependency.
