“…Este factor considera los efectos positivos que se produce al reducir el CH 4 , a CO 2 , es decir, una disminución de emisiones de GEI [20,23], puesto que las características del biogás producido contienen 50 % de metano, se espera la destrucción de este gas a través de su combustión. La destrucción del metano (el CH 4 , tiene una equivalencia de 21 veces el CO 2 ).…”

N.• 16, (Julio-Diciembre). pp. 36-42. ISSN: 1390-650X. Resumen AbstractLa provisión de recursos y energía para las ciudades es un reto para los planificadores urbanos. Más del 50 % de la población está concentrada en las ciudades y se espera que esta tendencia se incremente. Bajo el enfoque del metabolismo urbano, a las ciudades se las puede considerar como un ecosistema artificial, que requiere de materiales, nutrientes, agua y energía. La obtención de estos recursos ejerce una enorme presión sobre el medioambiente, no solo por el requerimiento de materia prima, sino por la generación de emisiones, residuos y efluentes. Por ello se plantea nuevas formas de recuperar los recursos, cambiando el modelo urbano desde un metabolismo lineal a uno circular. Una de las tecnologías que reúne estos requisitos es utilizar el biogás de los rellenos sanitarios para producir energía eléctrica. De esta manera, se disminuye la importación de energía hacia la ciudad y se reducen las emisiones de gases de efecto invernadero. Se focaliza el análisis al Relleno Sanitario de Pichacay, ubicado en la ciudad de Cuenca, Ecuador.The provision of resource and energy for the cities is the goal for the urban planning team. 50% or more of the people is living on the metropolitan area of the cities and this trend is expected to increase. Under the urban metabolism approach to cities they can be considered as an artificial ecosystem that requires materials, nutrients, water and energy. Obtaining these resources causes enormous pressure on the environment, not only by the requirements of raw material but by production of contaminants. This paper propose a new behavior of recovering resources arises, changing the urban model from a linear to a circular metabolism. One technology that meets these requirements is to use biogas from landfills to generation of electricity. Reducing purchasing of energy import to the city and emissions of greenhouse gases are reduced too. The analysis of Pichacay Landfill, located in the city of Cuenca, Ecuador, was prepared.Palabras clave: metabolismo urbano, energías renovables, biogás, sostenibilidad energética.

“…Both biogas technologies require less investment costs than the thermal conversion technologies and have smaller gate fees but the transport technology is cheaper. Energy production from LFG in Central Italy has been reported (Caresana et al, 2011). The authors have investigated the profitability of five alternative configuration plants for power generation and for CHP.…”

Possibilities of Using Landfill Biogas for Heating Agricultural Greenhouses in Crete-Greece

Biogas is currently produced in Crete-Greece from the two existing landfills in the island, as well as from the sewage treatment plants in Chania and Heraklion. Biogas produced in the two treatment plants is already used for co-generation of heat and power. However, since the quantities of landfills biogas and its energy content are significant, it can be used in the future either for heat production or for heat and power generation. Generated power can be fed into the grid and the produced heat can be used from a heat consumer. Since large heat consumers are not located nearby the existing landfills, there is the possibility for the creation of agricultural greenhouses in the surrounding agricultural areas which can utilize the generated heat. Landfill in Heraklion has an average biogas production of 1.43x10 7 NM 3 /year, almost five times higher than the landfill in Chania and the totally recoverable biogas from the two landfills can generate 16.73 GWh/year of electricity, in the case of a CHP plant, and enough heat for heating 15.4 hectares of modern greenhouses. In the case of direct heat generation, recoverable landfill biogas can heat 24.41 hectares of modern greenhouses. Since the global warming potential of methane is much higher than CO 2 , energy exploitation of landfills biogas in Crete will result in environmental benefits compared with its direct emission to the atmosphere.

“…In the Mediterranean area Energy production from LFG in Italy has been also reported by Caresana et al (2011) with reference to the landfill site in Marche region which receives about 100,000 ton yr -1 of urban and industrial waste. They investigated the use of an internal combustion engine, a CHP plant as well as micro-turbines for energy generation.…”

The landfill gas (LFG) produced from the existing landfill site in Heraklion city, Crete island, Greece, is not currently exploited to its full potential. It could however be exploited for power generation and/or combined heat and power (CHP) production in near future by fully unlocking its energy production potential of the gas generated from the landfill site. This gas (LFG) could feed a 1.6 MW el power plant corresponding to the 0.42% of the annually consumed electricity in Crete. The LFG utilization for power generation and CHP production has been studied, and the economics of three energy production scenarios have been calculated. An initial capital investment of 2.4 to 3.2 M €, with payback times (PBT) of approximately 3.5 to 6 years and Net Present Values (NPV) ranging between 2 to 6 M € have been calculated. These values prove the profitability of the attempt of bioenergy production from the biogas produced from the existing landfill site in Heraklion city, Crete. Based on the current economic situation of the country, any similar initiative could positively contribute to strengthening the economy of local community and as a result the country, offering several other socioeconomic benefits like e.g. waste minimization, creation of new job positions etc. by increasing, at the same time, the Renewable Energy Sources (RES) share in energy production sector etc. Apart from the favorable economics of the proposed waste to energy production scheme, all the additional environmental and social benefits make the attempt of a near future exploitation of the landfill gas produced in Heraklion, an attractive short term alternative for waste to bio-energy production.
