The proposed construction of a large-scale biogas and biofertiliser plant in Mazarrón has sparked serious backlash from residents of Camposol and Condado de Alhama, as well as environmental groups. Tensions have been building since the Murcia regional government published the project details in the official bulletin on July 4.

 

The plant, to be built by Biometano Mazarrón S.L., is expected to process 196,000 tonnes of organic waste per year, with a potential maximum capacity of more than 316,000 tonnes annually.

 

According to critics, this would mean around 540 tonnes of waste being treated every day, with an estimated 74 heavy goods vehicles accessing the facility daily.

 

Concerned residents have strenuously argued that the impacts on the local environment and public health could be severe. Among the main worries are the risks of air pollution, unpleasant odours, leakage of contaminated water, overuse of limited water resources, increased traffic and the potential contamination of both soil and aquifers.

 

The Neighbourhood Association of Camposol (AVC) has now formally submitted objections to the plant’s construction. In their allegations, the group emphasised that the plant’s proposed location just one kilometre from the Camposol urbanisation would seriously damage the health and quality of life of its residents, many of whom are elderly or infirm.

 

They also warned that house prices in the area would likely plummet, with some predicting that a widespread sell-off and departure of residents could follow if the project goes ahead.

 

As part of their response, the AVC has asked for the immediate suspension and denial of the Integrated Environmental Authorisation for the plant, which is planned for plots 1, 8, and 9 of polygon 8 in the Mazarrón municipality. The formal file reference is AAI20250009.

 

In addition, AVC representatives have requested an urgent meeting with the Mayor and members of the Camposol Council to discuss how the file is being handled by the local administration. Various other neighbourhood associations are also expected to attend.

 

The proposed site lies between the large residential developments of Camposol and Condado de Alhama, which together are home to thousands of people.

 

The controversy has been gaining traction both locally and regionally, with calls for a broader public debate on whether such industrial-scale biogas operations should be permitted so close to residential areas.
