oa Civil Engineering = Siviele Ingenieurswese - Africa's first landfill gas clean development mechanism project earns commendation : SAICE Awards 2007 - technical excellence
The management team of the Department of Cleansing and Solid Waste of eThekwini Municipality have turned conventional thinking on running landfills on its head with the revolutionary 'closed-loop' design and operation introduced at the Mariannhill landfill. The approach is to ensure that once waste comes onto site, nothing leaves. This entails constructing a good lining system, treating the liquid (leachate) produced, capturing and utilising the gas produced, and managing the odours that are always present with seven-day-old waste. The project was entered by the Durban Branch and earned a commendation in the category Technical Excellence.
