SANTA CRUZ DE TENERIFE, March 1. (EUROPE PRESS) –
The Cabildo de Tenerife has informed that it will take the approval of the concession of the company UTE Arico Green Gass for its installation in plot AG2 of the Environmental Complex of the island to the governing council of the island institution.
In this sense, the company has offered the 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 waste, which adds up to 129,256 tons per year, according to The Cabildo has reported in a press release.
The winning company will implement biomethanization processes in plot AG2 that consist of the anaerobic digestion technique, using the digestate for composting, which is considered material recovery. In this way, they indicate, any type of energy recovery is clear from the company’s proposal despite the fact that “this was allowed in the tender documents”.
This process will make it possible to close the bidding phase that began in 2021 through which it is intended to provide an industrial infrastructure to the Tenerife Environmental Complex that processes a quantity of waste that is currently deposited in a dumping cell.
This tender, they point out, 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.
In this regard, the president of the Cabildo de Tenerife, Pedro Martín, has pointed out that in these reports “it is clearly explained” that in this tender “there has never been room for incineration because it is expressly excluded, also making it clear that the European regulations, with national legislation, with the regulations of the Autonomous Community and, of course, with the Waste Plan of the island of Tenerife”.
For his part, the Minister for Sustainable Development and the Fight Against Climate Change, Javier Rodríguez Medina, underlined that with the government council’s approval of this contract, “Tenerife will take a step forward in waste management because it is the beginning of change of model, obsolete and antiquated that continues to function on the island, and that is clearly unsustainable”.
He added 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 throughout several stages, involves microorganisms and allows the most degradable fraction of organic matter to be transformed into biogas, a mixture of gases formed mainly by methane and carbon dioxide. and by other gases to a lesser extent (water vapour, CO, N2, H2, H2S).
