Conversion of low-temperature industrial waste heat into electricity

Specializing in the recovery of low-temperature industrial heat, the young company Entent is developing Pulse, a containerized plug-and-play machine capable of converting low-temperature industrial waste heat (between 60° and 150°C) into electricity. Several Pulse units can be installed on the same site to increase the amount of electricity produced. Initially intended for industrial use, Pulse can also be used for energy production or in data centers.

Automated floating barrier intercepting up to 80% of plastic waste in rivers

Indiggo co-founded in 2024 Plastic Vortex, a company specializing in combating plastic pollution in rivers and streams. The patented Vortex 150 system is designed to capture up to 80% of plastic waste carried by rivers downstream from urban areas before it reaches the oceans. The system uses natural currents to guide waste towards a conveyor that automatically dumps it into a skip where it is then sorted and sent for recycling. 

Low-carbon electrothermal oxidation system for industrial emissions 

Founded in 2025, Philectrify develops high-temperature, zero-emission technologies for industrial process heat applications. Its zero-fuel inductive oxidizer uses inductive heating of a corrosion-resistant silicon carbide (SiC) ceramic, enabling clean, uniform, and contactless gas heating up to 1,200°C, even in harsh oxidative gas atmospheres.  Built for industrial air pollution control systems, it enables a very efficient energy transfer with a small footprint (no external combustion chamber is needed).

Real-time detection of airborne particles with a link to their emission source 

Specializing in real-time air quality measurement, Oberon Sciences is developing a solution capable of detecting dust in the air in real time and automatically linking it to its source of emission. The technology which combines real-time particle imaging with automatic AI characterization makes it possible to accurately identify the respective share of emission sources. It offers targeted, automatic and coninuous recommendations to inform and act on the sources.

Dismantling of composites materials by supercritical fluids 

ADN Group together with the CNRS develops a technology aimed at dismantling multilayer composites based on the use of CO2 in supercritical conditions. This allows the polymer matrix to be selectively broken down without altering the reinforcing materials (fibers, films, inserts) thanks to a clean, non-toxic, and recyclable solvent. The precise and controlled separation of the different composite layers paves the way for high-value material recovery.

Transforming roofs, facades, and fences into controllable rainwater reservoirs

The young company Cactile uses buildings to better manage rainwater in the city. The « cactus building » transforms sloping roofs, facades and garden fences into controllable rainwater tanks, capable of storing thousands of litres of water without leaving a footprint on the land, and releasing this water by gravity, with no need for any pump and no energy consumption. In the event of a storm, the facade can be emptied preventively to act as a buffer reservoir for the urban drainage network. 

Automated waste sampling station 

NextWaste and Greyparrot have developed an automated waste characterization station. At the heart of the station is Greyparrot’s AI Analyzer, capable of identifying more than 111 waste classes across 13 major categories (plastics, paper, metals, textiles, composites, etc.) in real time. The station can process over 120 kg of waste in just a few minutes. All results are automatically compiled into detailed reports, accessible via a web dashboard or integrated directly into existing information systems. 

Complete recycling solution for greywater and treated water from WWTPs

An expert in water treatment, Nereus has developed the Fiber solution which can treat, filter and disinfect grey water by eliminating pathogens, organic pollutants and micro-particles to produce up to 80% A+ quality water. The water produced is ready to be reused for non-food and non-bathroom uses at home. Already deployed in a 232-home residence, the solution is also suitable for tourist complexes, campsites and community swimming pools. 

Mix of anti-E. coli bacteriophages for water treatment

Since 2017, Greenphage has been developing natural and precise antibacterial solutions for human health and ecosystems. Its treatments selectively eliminate pathogenic and dangerous bacteria present in wastewater or rainwater. Based on bacteriophages, the natural predators of bacteria, Waterphage can rapidly reduce E. coli populations by 2 to 3 Log in large volumes, naturally and without toxic residues. A first large-scale production unit will soon be commissioned (see €1.9 million raised in September).
