Our other licensed inventions include VR technology for the development needs of children with autism spectrum disorder as well as the bioconversion of food waste into high value-added products, power electronics technologies for energy saving, and air purification and water quality monitoring systems.

A biotechnology company, Vitargent (International) Biotechnology Limited, founded by CityU alumni, makes use of a technology developed at CityU to help improve the safety of food and daily necessities by rapidly testing for toxins through the use of zebrafish embryos.

We constantly explore ways to connect our research to emerging industry interests.

Our environmental scientists collaborated with the Hong Kong Research Institute of Textiles and Apparel to develop a new biological process based on fermentation that will be able to handle the recycling of blended textiles.

In addition, we have developed technology with HKRIT that converts food waste into polylactic acid, which can then be spun into fibres for use in textiles.

The CityU Shenzhen Research Institute, which opened in 2011, has served as an important strategic initiative for deepening engagement with mainland institutions and industrial partners in order to boost our research capacity and knowledge transfer capabilities.

Additionally, we enhance the provision of service learning and community engagement opportunities as a means to strengthen interactions with a range of external stakeholders, including government, non-governmental organisations and businesses.
