Landfill Bioreactors, A Step Towards Sustainability : Doña Juana Landfill Case Study
Abstract
This report compares the landfill bioreactor and conventional landfill gas to energy projects at Dona Juana Landfill in Bogota, Colombia. The SWANA first order decay formula was used to model methane emissions. The landfill bioreactor produces more methane in a shorter period of time than the conventional landfill and therefore more energy over a 20 year time span. When hidden costs are included in the economic analysis, the landfill bioreactor is a good option for energy generation. Both projects are still expensive when compared to conventional energy generation in Colombia. In both cases, the foreseen impacts are not as significant as the current ones. It is necessary to realign the current management at the landfill in order to assure the success of the landfill bioreactor project. This realignment must be based on stakeholder interests, driving forces, and barriers. As evident from this case study, landfill bioreactors can contribute substantially to sustainable development.
