BusinessCloud can reveal its EnviroTech 50 innovation ranking for 2025.
Readers of the online technology publication and an expert judging panel have together decided the 50 companies blazing a trail in green technology.
The EnviroTech 50 celebrates businesses of all sizes creating original technology for use in green energy, to protect the environment and boost sustainability.
Automotive emissions tech firm Catagen, based in Belfast, tops the ranking.
Liverpool-based PIN IoT, which digitises the collection process for the waste and recycling industry, is second ahead of London’s IPG Energy, which has developed a green replacement for diesel generators in difficult-to-decarbonise industries.
Perfect Sense Energy, based in the Greater Manchester town of Leigh, is fourth. The firm delivers tailored commercial solar PV (photovoltaics, or panels) solutions using over 15 years’ industry experience and trusted technology to cut costs, carbon and maximise efficiency.
UrbanChain (Manchester) completes the top five.
In seventh, behind Be.EV, is H2Origin Refills. The Manchester startup is on a mission to expand access to water bottle refill stations across public and private spaces, helping to reduce the packaging waste and CO₂ footprint associated with bottled water.
