Cambi has secured a contract to provide its thermal hydrolysis process (THP) technology to the Palma Wastewater Treatment Plant (EDAR II) in Palma de Mallorca, Spain. The plant is operated by the municipal water utility EMAYA. The project, awarded by a construction consortium comprising Tedagua, Lantania and Copasa, marks an important milestone in advancing sustainable wastewater treatment in the Balearic Islands.
Cambi's THP system, installed between two anaerobic digestion steps, maximises biogas production from the available wastewater solids, providing up to 25% net energy increase. Cambi’s THP system will also improve dewatering, reducing the volume of biosolids by up to 45%. The high-quality biosolids qualify for land application, enabling a circular economy with lower costs and a lower carbon footprint.
Per Lillebø, CEO at Cambi, remarked: “The project in Palma exemplifies Cambi's commitment to enabling cities to become more sustainable by reducing sludge volumes and producing more biogas to reduce costs and come closer to net zero carbon emissions. I look forward to collaborating with EMAYA and the contractor consortium to deliver a solution that improves operational efficiencies and enhances environmental outcomes in one of Europe's most popular tourist destinations."
The EDAR II wastewater treatment plant services part of the city of Palma and three adjacent municipalities, with peak demand of up to 750,000 inhabitants. The plant is undergoing a complex upgrade, including modernisation and expansion, reaching the capacity to handle the wastewater of one million people.
The scope of Cambi's delivery includes THP equipment and solutions designed to optimise the site's sludge treatment capacity. The THP system will be installed in 2026, with operations expected to begin by 2027.
