How to demolish 42,000 square meters of concrete from the Algarrobico after 20 years of work stoppage

The demolition of 42,000 square meters of concrete from the illegal hotel at El Algarrobico, located in Carboneras, Almería, has finally begun after more than two decades of legal delays and administrative limbo. The long-awaited decision to dismantle the structure marks the culmination of a complex and contentious urban planning dispute that has spanned nearly two decades. The operation will involve removing the massive volume of concrete and managing the resulting waste, which is estimated at around 60,000 cubic meters. The process has been shaped by a detailed agreement reached in 2011 between the Spanish government and the regional government of Andalusia, which outlined responsibilities for both demolition and environmental restoration. According to a study conducted by Tragsa in 2012 at the request of the Ministry of Agriculture, Food and Environment, then led by Miguel Arias Cañete, the initial cost estimates for the demolition and treatment of construction and demolition waste were set at 3.9 million euros. This figure was based on calculations that considered the hotel’s surface area of 43,840 square meters and its apparent volume of 142,480 cubic meters. These figures suggested that the volume of debris generated would amount to approximately 60,000 cubic meters. Additional costs included 304,920 euros for preliminary studies and project drafting, and 217,800 euros for the direction of works, safety, and health measures. The environmental restoration of the El Algarrobico site, assigned to the regional government, was initially estimated at 1.5 million euros. The restoration work, which falls under the responsibility of the Andalusian government, will commence once the demolition and waste management phases are completed. The affected areas have been divided into three distinct zones: Zone A, occupied by the hotel itself and spanning 3.28 hectares; Zone B, impacted by earth movements; and Zone C, partially affected by earthwork and road construction. The restoration plan outlines four stages, with the first two focusing on creating a harmonious landscape and stabilizing the terrain. These initial steps carry a budget of one million euros. The third stage involves establishing a protective vegetation cover to prevent erosion, with an allocated budget of 319,000 euros. The fourth and final phase includes irrigation, monitoring of invasive species, and erosion control, with an estimated cost of 84,000 euros. Since the 2012 study, the cost of demolition tasks could have increased by up to 50% due to rising energy prices and other economic factors. Despite these potential increases, the exact current cost remains uncertain. The government is responsible for the demolition and removal of waste, while the regional government oversees the ecological recovery of the surrounding area. The entire process requires coordination between multiple agencies and is expected to take several months to complete. The long-standing legal battle over this unauthorized construction has highlighted broader issues related to unchecked urban development along Spain’s coastline. The El Algarrobico case has become emblematic of the challenges faced in enforcing environmental regulations and ensuring sustainable land use. As the demolition proceeds, officials will need to address not only the technical aspects of the operation but also the broader implications for local ecosystems and community relations. The completion of this task will represent a critical step toward restoring the natural environment of the region.
