Enagás Renovable and Agropor sign an agreement to sustainably recover the bio-waste generated by pig farming in the Region of Murcia

11 de March de 2024

Madrid, 12 March. – Enagás Renovable, a pioneer in the development of renewable gases in Spain, and Agropor, a company dedicated to pig farming and a benchmark in the Region of Murcia for more than 50 years, have signed a collaboration agreement to manage the bio-waste generated on pig farms and convert it into biomethane and organic fertilisers for agriculture.

Through this collaboration, Agropor joins a project focused on the circular economy, with the aim of achieving the goal of zero waste. A substantial part of the organic waste generated at Agropor’s Murcia farms will be transported to the biomethane facilities planned by Enagás Renovable in the region. This waste will undergo a process of digestion by anaerobic bacteria, which operate in the absence of oxygen, resulting in the production of biomethane. The biomethane generated, 100% renewable energy, will be injected into the gas network infrastructures, contributing to the reduction of emissions.

This is a commitment to promote a circular and sustainable economy as the by-products resulting from the process (digestate) will be treated in the facilities themselves, obtaining two organic-based solutions that can be used in agriculture as solid fertiliser through composting processes and liquid fertiliser (fertigation) through a purification process, complying with current fertiliser regulations. In addition, these organic fertilisers can also be applied in Agropor’s agricultural activities, thus complementing its livestock farming activities, in a complete circular economy cycle.

According to Antonio Illescas, Director of Business Development and Operations of the biomethane area at Enagás Renovable, “this agreement allows us to continue advancing in the sustainable management and recovery of waste from the livestock sector in the Region of Murcia, which has great potential for biomethane production”. Likewise, Gustavo Alfonso Peralta, Project Director of the Agropor Group, emphasised that, “this collaboration is of great value both in environmental terms and in the management of the organic waste generated. Through this agreement, we are implementing a circular economy, turning a waste into a valuable and renewable resource: biomethane, produced directly in the vicinity of our facilities, and, in addition, this process allows us to obtain high quality organic fertilisers, which further strengthens our environmental sustainability”.

Anaerobic digestion is a sustainable alternative for the management of bio-waste from the agro-livestock sector with great environmental and economic benefits. This process avoids landfilling waste, significantly reduces greenhouse gas emissions into the atmosphere, offers a new sustainable use for bio-waste and, in addition, the biomethane produced contributes to the decarbonisation of the economy and energy independence.
