<pclass="column"style="float: left; width: 50%; padding-right: 40px;">We used mutated varieties of the PETase enzyme which can break down and covert polyethylene terephthalate (PET) plastic into more usable monohydroxyethyl terephthalate (MHET). These were synthesised these enzymes and then immobilised onto silica beads. These beads could then be placed in water to break down PET. </p>
