A life cycle assessment into energy recovery from organic waste : a case study of the water treatment facility of SABMiller Newlands Brewery

This thesis aims to assess the avoided environmental burdens of waste water treatment by additional on-site anaerobic waste water treatment prior to municipal treatment and disposal to river. It investigates the opportunity for further burden reduction by way of energy capture from generated biogas and re-integration within a plant-wide environment. The Life Cycle Assessment (LCA) was the analytical tool used to quantify burdens attributable to additional on-site effluent treatment, and further quantify the burdens avoided due to energy capture and re-integration. This thesis was born from the opportunity for energy reclamation from biogas, generated by SABMiller Newlands Brewery anaerobic digester. Western Cape power failures prompted the search for alternate energy sources, focusing SABMiller attention to the currently flared biogas emitted from the SABMiller Newlands effluent treatment facility.
