Andrew Ward discusses transforming regional wastewater treatment using high-rate algae ponds Jun 5, 2023 | ![User Icon](https://www.awa.asn.au/hubfs/website-assets-2021/icons/icon-user.svg "User Icon") by Justin Matters ![](https://www.awa.asn.au/hubfs/R%C3%A9utilisation_%C3%A0_Attaouia_effluent_utilis%C3%A9_(11323854204).jpg) How do we solve a complex issue like sludge, greenhouse gases and wastewater? The answer may lie in high-rate algae ponds.  Andrew Ward (Research Fellow at the Australian Centre for Water and Environmental Biotechnology at the University of Queensland) discusses his research on transforming regional wastewater treatment using high-rate algae ponds. Originally presented at Ozwater'23, Andrew joins Jo Taranto on Season 6 of the Australian Water Association's podcast series to outline the benefits of utilising high-rate algae ponds correctly to form part of a net zero approach to reduce overall greenhouse gases.
