UWI Technology Ltd was set up in 2009 to develop a patent pending elapsed time indicator (ETI) known as the UWI Label.  Inventor Pete Higgins came up with the idea of a smart label which would indicate how long any jar had been opened for and, therefore, whether or not the food inside had gone off.


The company was looking to establish a collaborative project with an academic group to help advance the technology of the label and develop its commercial potential, ultimately providing a working demonstration of the UWI label for investors.


Through Interface, UWI was introduced to Heriot-Watt University, who had renowned expertise in micro-engineering and colour chemistry.

Besides having the huge potential to be an effective consumer food waste reduction solution, it was soon realised that the idea had significant global applications such as the pharmaceutical industry, medical science and aeronautical manufacturing.  The collaboration received Scottish Funding Council Innovation Voucher funding, followed by further funding support from the EDTC/Product Realisation Centre Scheme for expanding the work to meet additional commercial demand.


  • Significant progress has been made towards the realisation of the UWI Label.
  • There are four to five potential innovations identified by the UWI patent attorney.
  • UWI was the beneficiary of £50K from Barclays Take One Small Step competition as well as £600K in new investment.
  • It is forecasted that staff and turnover for the company will significantly increase.
  • The idea has significant global applications from food and drink to aeronautical engineering
