Development of biomaterials from sustainably produced macroalgae feedstocks
Upgrading and maintaining large-scale wastewater treatment plants (WWTPs) is notably expensive, particularly in rural areas of New Zealand. Freshwater macroalgae ponds may offer a cost-effective alternative for wastewater treatment in these areas. These ponds produce significant amounts of residual …
