ONTARE. REVISTA DE INVESTIGACIÓN DE LA FACULTAD DE INGENIERÍALos Residuos Sólidos Municipales, son un nuevo objetivo de las admi- nistraciones municipales debido a las consecuencias negativas que trae su manejo y gestión inadecuados: problemas de salud, contaminación, etc. En Colombia, la práctica más utilizada para el manejo de los residuos sólidos municipales es la disposición final en rellenos sanitarios, sin embargo, no todos los residuos que se disponen son no aprovechables: (a) la fracción inorgánica que no tuvo separación en la fuente, pierde su posibilidad de incorporarse en cadenas de valor; (b) la fracción orgánica, que se produce durante la preparación de alimentos en casas, restaurantes y empresas, tiene usos potenciales como el abono, que es el más tradicional u otros procesos que usan dicho material como inicio. Este artículo busca explicar dos posibilidades de uso y valorización de la Fracción Orgánica de los Residuos Sólidos Municipales (FORSM o FORSU), desde los resultados obtenidos en dos investigaciones realizadas en la Especialización en Gestión de Residuos Sólidos de la Universidad EAN. ABSTRACTThe Municipal So/id Waste has become a new target for the municipal government due to the negative consequences it may bring in case of inadequate management: diseases, pollution, etc. In Colombia, the most frequent action taken is the final disposa/ in /andfi/1, nevertheless, not al/ the so/id waste is real waste or unusable material: (a) the inorganic fraction that, due to no source separation, loses the possibility to be used and included in value chains, and (b) the organic fraction, which is produced during food processing in houses, restaurants and enterprises, has potential uses such as compost, which is the most traditional one, or new uses as matter for other processes  . This paper intends to explain two possibilities for the use and valorization of the Organic Fraction of Municipal So/id Waste (OF­ MSW), from the research results of two works in the Specialization in So/id Waste Management of the EAN University

In comparison to lignocellulosic biomass, which is suitable for thermo-chemical valorization, the organic fraction of municipal solid waste (OFMSW) is mainly treated via composting or anaerobic digestion (AD). An efficient utilization of OFMSW is difficult due to variations in its composition. Based on the characteristics of OFMSW, hydrothermal treatment (HTT) experiments at temperatures < 200 °C as an alternative OFMSW-processing were evaluated in this study. The raw OFMSW was characterized with a dry matter (DM)-based organic dry matter (oDM) content of 77.88 ± 1.37 %DM and a higher heating value (HHV) of 15,417 ± 1258 J/gDM. Through HTT at 150, 170 and 185 °C, the oDM contents as well as H/C and O/C ratios were lowered while the HHV increased up to 16,716 ± 257 J/gDM. HTT led to improved fuel properties concerning ash melting, corrosion stress and emission behavior. Negative consequences of the HTT process were higher contents of ash in the biochar as well as accumulated heavy metals. In the sense of a bioeconomy, it could be beneficial to first convert raw OFMSW into CH4 through AD followed by HTT of the AD-digestate for the generation of solid fuels and liquid products. This could increase the overall utilization efficiency of OFMSW.

With the implementation of new policies supporting renewable natural gas production from organic wastes, Canada began replacing traditional disposal methods with highly integrated biogas production strategies. Herein, data from published papers, Canadian Biogas Association, Canada’s national statistical agency, and energy companies’ websites were gathered to gain insight into the current status of anaerobic digestion plants in recovering energy and resource from organic wastes. The availability of materials prepared for recycling by companies and local waste management organizations and existing infrastructures for municipal solid waste management were examined. Governmental incentives and discouragements in Canada and world anaerobic digestion leaders regarding organic fraction municipal solid waste management were comprehensively reviewed to identify the opportunities for developing large-scale anaerobic digestion in Canada. A range of anaerobic digestion facilities, including water resource recovery facilities, standalone digesters, and on-farm digesters throughout Ontario, were compared in terms of digestion type, digester volume, feedstock (s), and electricity capacity to better understand the current role of biogas plants in this province. Finally, technology perspectives, solutions, and roadmaps were discussed to shape the future in terms of organic fraction municipal solid waste management. The findings suggested that the biogas industry growth in Canada relies on provincial energy and waste management policies, advanced technologies for diverting organic waste from landfills, improving biogas yield using existing pretreatment methods, and educating farmers regarding digester operations.
