Metropolitan plant comprehensive waste treatment Presentation The Ecoparc de Barcelona is an environmental facility dedicated to comprehensively treating waste from the metropolitan area of Barcelona. We take advantage of organic and undifferentiated municipal waste (brown and gray containers) through various treatments, such as the selection of recyclable materials, composting and methanization. We are at the service of the population and the municipalities that carry out selective collection, based on the commitment we acquired in the Metropolitan Municipal Waste Management Program. OBJECTIVES Minimize the environmental impact of the facility. Improve the safety and health conditions of the personnel. Adapt to changes in the quality and quantity of the waste that reaches us. Optimize biogas production. Maximize compost production. Minimize plant rejection (waste that we cannot take advantage of). Minimize the percentage of organic matter contained in the plant rejection. Recover as much recyclable materials as possible. We bring the complete waste treatment process closer to citizens. Process in three phases Pretreatment Methanization and cogeneration Composting One of the objectives of the Ecoparc de Barcelona is to take advantage of the organic matter from selective collection to produce biogas through the methanization process. Before methanization, the organic matter separated during pretreatment is subjected to a wet treatment: it is introduced into three stirrer tanks ( pulpers ), where it is mixed and disintegrated in water. In addition to diluting it, the movement of the tanks causes sand and pieces of glass (inert) to settle, and plastics (floating) emerge, which were still mixed with the organic matter. The resulting pulp is transported to the interior of the digesters, which are four 4 tanks with a capacity of 6,700 m3. The digesters act as anaerobic fermentation reactors: they keep the pulp closed without contact with oxygen and at a temperature of 37 ºC for 20 days. During this time, anaerobic fermentation releases biogas, a mixture of methane and carbon dioxide, which is used as a renewable fuel to generate electricity and heat. The biogas is led to a gasometer, which stores it and regulates the outlet flow. The gas is kept at a pressure equivalent to atmospheric pressure (20 mb). From the gasometer, the biogas is directed to the cogeneration plant, equipped with 5 Jenbacher 20-cylinder engines and a total power of 5.24 MW. The combustion of the biogas generates electricity, which is exported to the grid, and heat, which is used to keep the temperature of the digesters stable at 37 ºC. Every year, the Barcelona Ecoparc produces an average of 13,000 MWh, equivalent to the electricity consumption of some 3,000 families for a whole year. This electricity, coming from a renewable energy source, offsets 4,536 tons of CO2 emitted into the atmosphere, according to sources from the Ministry of the Environment.
