Growthpoint Properties has installed an on-site, anaerobic digester at its N1 City Mall property in Cape Town, which uses organic waste to produce green electricity, hot water and fertiliser.

During the Future Cities conference track at African Utility Week and POWERGEN Africa in Cape Town in May, a case study will be presented on South Africa's first Waste Transformer at the shopping centre and will be followed by a discussion on how waste-to-energy plants can be made more competitive.
