A British company using AI to help optimise recycling and a Dutch start-up transforming air into drinking water are among the cleantech innovators that Amazon has decided to support through its Sustainability Accelerator.
The e-commerce giant has confirmed the 2025 Climate Tech cohort of its Sustainability Accelerator, selecting 11 winners from more than 550 applications.
All applicants had to prove how they were addressing at least one of three environmental challenges: energy efficiency, waste reduction and water management.
UK-based Greyparrot was selected for its work to enhance recycling rates. It has developed an AI-assisted computer vision system which observes waste conveyor belts, identifying and categorising materials in real-time. This system can recognise more than 100 types of waste.
Another innovative British organisation, Mhor Energy, was selected for its innovation in battery technology. It has developed an innovative flow battery that stores energy in liquid form, which can work efficiently even in high temperatures.
Mhor’s batteries could be suitable for solar farms. They can store energy for longer than typical lithium-ion batteries and also have a longer operational lifespan of up to 25 years.
“Our journey began with a simple frustration over the lack of innovation in heating systems,” said Mhor’s CEO and founder, Jamie Lindsay.
“This led us to develop a system that uses environmentally friendly liquids to store electricity. By creating a heat-resistant, non-flammable solution, we’re helping industries transition to renewable energy while significantly reducing their operational costs and environmental impact.”
The class of 2025
In addition to Greyparrot and Mhor, nine other organisations were chosen to benefit from the Accelerator. They are:
- Solaq, whose shipping-container-based system transforms atmospheric moisture into drinking water—even in areas with low humidity.
- Vuala, creators of a bio-mechanical system which uses specialised microorganisms to process food waste into an odourless form.
- Cartesian, which developed a next-generation thermal battery.
- Over Easy Solar, innovators of a lightweight solar system which stands up vertically.
- Active Surfaces, developers of ultra-thin, flexible solar sheets made using perovskite.
- Omniflow, a Portuguese company offering energy-efficient streetlights with built-in wind and solar.
- Blue Frontier, creators of air conditioning systems which use up to 90% less energy, thanks to the use of liquid desiccant technology.
- Belgian firm Shayp, whose water leak detection technology has already helped building operators save more than 21 billion litres.
- NANDO, which has created a tech platform to track bins and large waste containers to analyse their contents in real-time. It can accurately recognise more than 70 types of waste.
“What stands out about this cohort is their combination of technological innovation and practical applicability,” said Amazon’s European director of sustainability and packaging operations, Olivier Pellegrini.
“These founders are developing technologies that have real potential for implementation within our operations and could be truly transformative at scale.”
