About: The Anaerobic Digestion Guideline is a practical guideline for wastewater practitioners and managers involved in the planning, design, operation, maintenance and management of WWTW. The guideline is based on the premise of the American “Capable Plant” concept which demonstrates a holistic management process for the beneficial use of biosolids and biogas naturally generated during the anaerobic digestion process. The Guideline will form the basis of a series of training and capacity building events for municipalities offered through WISA.

Disclaimer: The use of the Guideline is restricted to private use and may not be used for income generation purposes. Should any content be cited from the guideline, kindly acknowledge the authors and GIZ as publisher. The content of the guideline has been compiled by subject matter experts, peer reviewed by sector experts and tested during three pilot training sessions in municipalities.

South African wastewater treatment works (WWTW) have a high savings potential on their electricity bill through the generation of biogas from the anaerobic digestion of sludge for their own consumption. The objective of this study was to review the potential of all municipal WWTW larger than 10ML/day for a biogas and CHP project.

One of the key aspects in developing a biogas market in South Africa and understanding the full potential of the technology is unpacking the specific skill-sets required and job potential that the biogas industry holds. Therefore, the objective of this study was to explore in detail the employment potential from biogas along the main phases of a typical biogas project, as well as 4 categories of project sizes. The study also looked at the various skills and levels thereof needed for each project phase.
