Low-temperature anaerobic digestion for wastewater treatment

► Anaerobic digestion (AD) wastewater treatment is environmentally sustainable. ► Conventional, heated AD is not suitable for cold, low-strength wastewaters. ► New information on biology has underpinned low-temperature LTAD process development. ► LTAD now successfully implemented at laboratory and pilot-scale. ► Potential for integration with other technologies to maximize resource recovery.
