Specific research activities include the monitoring of ocean acidity and its effects on corals and shellfish, and this information is reported to the UK government. As part of its research into sustainability, PML uses technology such as photo-bioreactors to cultivate algae that could be used in the production of biofuels or in the treatment of waste water. Aside from its environmental research, PML also works alongside the Boots Group to investigate the use of algae in skin-care products, since these organisms utilise sunscreen-like compounds to protect themselves from the sun.
