Avientus

Avientus is revolutionizing the way goods move - Anything, Anywhere, Anytime. We develop fully electric, fixed-wing drones with vertical take-off and landing (VTOL) capabilities to autonomously transport a wide range of payloads, from parcels and food to medical supplies and spare parts, across both urban and rural environments. Our system enables bi-directional, autonomous logistics, opening up fast, flexible, and sustainable delivery routes, all without relying on existing infrastructure. What sets us apart? It’s not just the drone, it’s the system. Avientus combines intelligent route planning, autonomous payload handling, and seamless ground operations to deliver a fully automated logistics workflow, designed for effortless integration into existing supply chains. Proudly designed and built in Switzerland, we unite precision engineering with environmental responsibility. Why it matters? Our technology enables faster and more efficient delivery of essential goods, significantly reduces emissions compared to conventional methods such as cars and helicopters, and powers smarter, cleaner logistics networks for the future.

GR3N SA

GR3N SA is a Swiss company founded in 2011 that developed an innovative process, based on the application of microwave technology to an alkaline hydrolysis, which provides an economically viable recycling process of Polyethylene Terephthalate (PET), allowing the industrial implementation. This new process can potentially change how PET is recycled worldwide, with huge benefits both for the recycling industry and for all the polyester value chain. In the past, many efforts were made to transfer chemical recycling from research labs to industry but the economic aspects blocked the proposed solutions. Thanks to the DEMETO (Depolymerization by MicrowavE TechnolOgy) technology developed by gr3n this approach becomes real. gr3n has a massive advantage with respect to its competitors because it can supply a chemical recycling solution (i.e., closing the PET lifecycle, offering polymer grade material, treating waste, lowering carbon footprint) providing cost savings for players in the value chain. The input materials for the process can be post-consumer and/or post-industrial polyesters, both from bottles (colored, colorless, transparent, opaque) and textile (100% polyester but also with up to 30% of other materials like PU, cotton, polyether-polyurea, etc.). The reaction output is a mixture of building block derivatives, which are then isolated and purified. Monomers can be endlessly re-polymerized to provide brand-new virgin PET or any other polymer that is using one of the monomers. As mentioned for the depolymerization step, every time we run a polymerization, we obtain a brand new polymer, where the technical features depend on the monomer purity and the polymerization conditions.

Coachbetter

Coachbetter is the unified operating system for grassroots football clubs - the only platform that connects club operations and coaching in one system.
