| Summary: | Recently, there is a growing tendency in developing countries to build and consolidate stronger solid waste management systems. However, the authorities and police-makers are still struggling to use waste as a resource to generate renewable energy. Colombia has experienced reasonable economic growth over the past 20 years backed with an increase in waste generation. Nonetheless, waste management is still a challenge for the country. A few initiatives are being implemented nowadays in small municipalities to recover the organic fraction of municipal solid waste. In Sabana Centro, a small province in Colombia, six municipalities are currently implementing pilot plans to recover organic waste, two have at least two organics collection routes and send them to compost processes, and one of them (Cajicá) retrieves all the organic fraction and produce soil amendments. These facts are strong evidence that there is a growing interest in the province to implement technologies to recover organic waste. In this multidisciplinary thesis, an assessment of a waste-to-energy process for Sabana Centro by using dry anaerobic digestion and participatory approaches is proposed. First, the most relevant factors that affect municipal solid waste management systems in Colombia were outlined through a combined impact analysis and participatory methodology. Then, dry anaerobic digestion of organic fraction of municipal solid waste using samples from two municipalities in Sabana Centro was evaluated to define possible strategies to increase biogas and methane production. Both strategies were biological pretreatment using white rot fungi and co-digestion with municipal grass waste. |
