The project promoters, who had already obtained urban planning authorization during the summer, anticipate that the plant's construction will last approximately two years. Once operational, the facility is designed to transform around 500,000 tons of organic waste into biomethane.

The CIP group emphasized that the plant will utilize cutting-edge technology, including an air treatment and deodorization system to prevent any odor emissions outside the facilities. Furthermore, they guaranteed that farm waste, such as pig slurry and cow manure, will be transported in sealed tank trucks to eliminate any risk of spills or odors during transit to La Sentiu de Sió.

Raw materials include pig slurry, cow and calf manure, poultry litter from local farms, slaughterhouse remnants, and other non-hazardous industrial organic waste from companies in the area. Promoters state that over 80% of the slurry they manage will come from farms located within a 15-kilometer radius of the plant, claiming adherence from more than 350 farmers across the Noguera, Pla d'Urgell, and Urgell regions.

Despite administrative approval, the project faces significant legal opposition. Opposing entities and four town councils from Ponent filed two administrative contentious lawsuits before the High Court of Justice of Catalonia (TSJC) a week ago. The plaintiffs plan to request precautionary measures to prevent the Cobirgy promoters from starting construction in early 2026.
