Challenges impeding South African municipalities from adopting waste-to-energy schemes : an exploratory approach
type: CreativeWork
description: As a resource, waste is abundantly available but largely underexploited in South Africa. Through waste to energy transformation, waste offers a variety of benefits that could address socio-economic and environmental challenges such as energy poverty, decreasing landfill space and greenhouse gas (GHG) emissions. As South Africa becomes more urbanised, the urban population will rapidly increase and greater effort will be required to manage waste and provide energy services. Municipalities have the potential to deal with these challenges and realise many benefits by transforming and valorising waste through waste-to-energy (WtE) schemes. The most prevalent WtE technologies include biological (biochemical conversion) and thermal (thermo-chemical) based conversion technologies. Biological technologies mainly employ anaerobic digestion (AD) of waste to produce biogas which can be used directly or upgraded to other secondary energy carriers. Landfill gas recovery is also based on anaerobic breakdown of waste in landfills. Thermal treatment methods that produce heat and electricity include combustion, gasification, and pyrolysis. The most common form of WtE conversion technology is combustion or incineration of solid waste. In the developing world, AD is the most common technology especially for small scale and domestic applications. WtE technologies have been successfully deployed in many developed as well as some developing countries but there are limited initiatives in South Africa due to a number of barriers to the deployment of the technology. This study explored the barriers to wide scale deployment of WtE technologies in South Africa with a specific focus on adoption challenges faced by local municipalities specifically in the Western Cape Province. Four objectives were identified, namely: (1) investigate existing waste management methods, challenges experienced and current (proposed) interventions; (2) investigate local municipalities' efforts to implementing WtE sc…
