The Council of Tenerife will take to the Island Government Council the approval of the concession of the company UTE Arico Green Gass for its installation in plot AG2 of the Environmental Complex of Tenerife. The company has proposed an offer based on el treatment of 90,454 tons per year of organic fraction from the mechanical treatment plant, 24,702 tons per year of sewage sludge and 14,100 tons per year of livestock wastewhich adds up to 129,256 tons per year.
The winning company will implement biomethanization processes in plot AG2, consisting of the anaerobic digestion technique, using the digestate for composting, which is considered material recovery. Therefore, any type of energy recovery is clear from the company’s proposal, despite the fact that this was allowed in the tender documents.
This closes a bidding process that began in 2021 through which it is intended to provide an industrial infrastructure to the Tenerife Environmental Complex to process a quantity of waste that is currently deposited in a dumping cell. This tender has been endorsed three times by a study by the University of La Laguna and by two reports by technicians from the Service for Sustainable Development and the Fight Against Climate Change.
The President of the Council, Peter Martinalready indicated in January that these reports clearly explain that in this tender “there has never been space for incineration, because it is expressly excluded, making it clear, moreover, that it complies with European regulations, with national legislation, with the regulations of the Autonomous Community and, of course, with the Waste Plan of the island of Tenerife”.
The Minister for Sustainable Development and the Fight against Climate Change, Javier Rodriguez Medinapointed out that “with the approval of the Governing Council of this hiring Tenerife will take a step forward in waste management, because it is the beginning of the change of model, obsolete and antiquated that continues to function on the island, and that is clearly unsustainable”. The counselor pointed out that “after all the controversy generated from little contrasted and interested information, it has been possible to carry out the tender and thanks to this, more than 130,000 tons of waste per year will no longer be buried to obtain new resources.”
Biomethanization or anaerobic digestion is a biological process that, in the absence of oxygen and through various stages involving microorganisms, allows the transformation of the most degradable fraction of organic matter into biogas, a mixture of gases formed mainly by methane and carbon dioxide. of carbon and by other gases to a lesser extent (water vapour, CO, N2, H2, H2S,…).
