Renter provides an electric two-wheeler subscription service for last-mile delivery in Central and Eastern Europe. We replace petrol scooters and delivery cars with EU-compliant e-bikes and e-mopeds engineered for long, demanding courier shifts in dense urban areas. Riders and logistics companies pay a weekly or monthly fee that includes the vehicle, all maintenance, and a 30-minute repair-or-replace guarantee, ensuring zero downtime and no income lost to breakdowns. Active in Bucharest and Chișinău, we focus on high-traffic neighbourhoods where delivery activity and emissions peak. By combining low-emission vehicles with circular repair processes and the recycling of worn parts, we help cities cut CO₂ while giving couriers a more stable and predictable way to work. Renter has grown from a high-school project into a cross-border mobility company with €700k raised, 300 active vehicles, and approximately €36,000 in monthly recurring revenue. We primarily support low-income and immigrant couriers and have earned more than 530 five-star reviews from riders. A core value of our team is a strict “zero-waste” mindset, not just in materials, but in eliminating wasted time and money for couriers. Instead of navigating repairs, research, and unreliable vehicles, riders receive a ready-to-use solution that makes sustainable mobility simple, fast, and accessible.

Wastespresso is a waste management and materials company focused on the collection and upcycling of spent coffee grounds from offices, corporate headquarters, hotels and hospitality venues. The company addresses the environmental impacts associated with organic waste disposal and the continued use of petroleum-based plastics by transforming coffee waste into reusable raw materials and products. Through a proprietary processing approach, the company converts this waste stream into coffee-based granules that can be used as an alternative input for bioplastic production. These granules serve as a raw material for the manufacture of reusable consumer and industrial products, offering a non-fossil-based option for plastics. The company’s solution avoids the use of food-based bioplastic feedstocks such as corn or vegetable oils, instead relying on an abundant and underutilized waste stream. By valorizing up to 99% of collected coffee grounds, Wastespresso supports circular material flows and reduces emissions associated with waste disposal and virgin plastic production. Its products are marketed to both business and consumer markets, with applications ranging from reusable items to customized plastic components.

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.

Nepser has developed FloCatch, a passive bubble-based waste collection system designed for marinas, ports and rivers. The system addresses floating and submerged macro plastic waste by using a surface bubble curtain that operates without compressors. Instead, it leverages oxygen dissolved in water and the Bernoulli principle to create a continuous barrier that directs waste to a collection unit, where it is automatically transferred to shore. FloCatch is a permanent, low-cost solution suitable for both stagnant and flowing waters. It can be deployed as a defensive line in port berths to prevent pollution, including oil spills, from spreading to open waters. The system is especially suited for preventing plastics from reaching areas like the Pacific Garbage Patch by intercepting them early. Compared to alternatives like SEABIN or conveyor boats, FloCatch operates with lower operational costs and greater efficiency in real-world aquatic environments.

İlker Teknik Ltd. has developed a digital platform that enables comprehensive, transparent and real-time monitoring of waste collection, inventory and management processes across multiple stakeholders.
