Ozone can oxidise plastics leading to changes in the characteristic properties. Samples of traditional plastics and bioplastics were exposed to ozone in a laboratory setting and analysed in terms of strength, colour and surface properties.

The ozone was produced in the laboratory using both a lab- scale ozoniser and a commercial ozone generator. Both devices use an electrical discharge to convert oxygen into ozone. The levels of ozone produced were quantified using redox titration.

In addition, a commercial ozone detector was used to measure the levels of ozone accumulation within the school building, particularly in vicinity of high-temperature printers.
