The UK heat of Europe-wide competition to find the latest talent working in clean technology.
Innovation Birmingham Campus hosted the heat of the 'CleanLaunchpad' competition in which the eventual winners and two runners up will collectively receive £13,600 (€17,500) to develop their clean-tech products and services.
The competition is one of the initiatives being run by Innovation Birmingham's Climate-KIC team.
Cambridge-based bio-glue manufacturer Cambond was named the overall winner of CleanLaunchpad UK.
The company makes adhesives from biomass feedstocks including algae using a low-carbon, cost-effective process.
It will now progress to the European-wide final in Valencia at the end of October where it will be joined by the UK joint runners-up.
Derby-based Adaptavate has developed a natural compostable plasterboard, suitable for use on heritage buildings and traditional homes, while London company Desolenator has produced a solar-powered means of desalinating water.
Catherine Shelley, Innovation Birmingham's Climate KIC programme development and delivery officer, said: "Many of the innovative concepts that came onto the CleanLaunchpad competition at the beginning of the process have made genuinely impressive progress with developing their products, plans for reaching the mass market and the quality of their pitching.
"We are confident that Cambond, Adaptavate and Desolenator will do the UK proud in the final and I really hope that all entrants keep developing their ideas."
