TL;DR: Algae biofuels (e.g. biogas, ethanol, biodiesel and crude bio-oil), could be produced from the algae harvested from wastewater HRAPs, with biofuel and recovered nutrient fertilizer being by-products, and greenhouse gas abatement results from both the production of the bio Fuels and the savings in energy consumption compared to electromechanical treatment processes.

TL;DR: The preliminary findings indicate the potential to scrub C02 from biogas using high rate pond water without decreasing the effectiveness of wastewater treatment and enabling increased recovery of wastewater nutrients as algal biomass.

TL;DR: The results suggest that covered anaerobic ponds treating agricultural wastes in New Zealand have great potential to reduce odour and GHG emissions and recover renewable energy, while producing an easy to handle effluent for land irrigation or further treatment.

TL;DR: A review of the current knowledge of the processes causing these emissions and the amounts emitted is reviewed in this article, where it was found that methane emissions from ponds are the largest contributor to the total GHG emissions from effluent in managed manure systems in New Zealand.

TL;DR: A simple model of the energy yields of various wastewater treatment technologies is demonstrated to demonstrate how minor shifts in technology selection can lead the industry from being identified as predominantly energy intensive, to being recognised as a source of energy resources.
