GSA Servicios Ambientales

What GSA Servicios Ambientales does

GSA Servicios Ambientales (legal entity: Guadaíra Servicios Ambientales, S.L.) is a privately held Spanish environmental services company founded in 1995 and headquartered in Alcalá de Guadaíra, Sevilla. The company provides end-to-end waste management services to municipal and regional governments across Spain, with operational concentration in Andalusia. Its service portfolio spans municipal solid waste collection and treatment, hazardous and non-hazardous waste management, biosanitary waste sterilization (one of only two authorized facilities in Andalusia, with capacity for 60 tonnes per hour post-sterilization), landfill sealing and rehabilitation, biogas extraction and electricity generation, and specialized selective glass collection at large-scale events. The company also operates circular economy initiatives including a flagship partnership with Hotel Meliá Sevilla (the Aceite Circular project) that transforms hospitality waste into organic fertilizer for olive groves, producing olive oil that returns to the hotel.

In 2025, GSA managed 329,954 tonnes of waste, including 260,000 tonnes transported annually from LIPASAM's transfer plant in Seville to its Centro Integral de Tratamiento RSU Montemarta Cónica. Its technology stack includes Movertis fleet management with real-time geolocation and route optimization, an autoclave-based biosanitary sterilization line (operating at 2.5 atmospheres and 134°C for 10 minutes), landfill biogas-to-energy infrastructure across five Spanish regions, and an active R&D pipeline (C-Biofert/CompoRISE funded by CDTI-FEDER, LFG2H2 green hydrogen, LFG2Jet aviation biofuel, All to Gas biomethane) targeting biofertilizers, green hydrogen, biofuels, and biomethane from waste streams. The company holds ISO 9001/14001/45001/50001, EMAS, SACE carbon registry, Bureau Veritas water footprint verification, ODS Strategy, and Forética SGE 21 certifications.

Revenue is generated primarily through multi-year public procurement contracts with municipal councils and the Junta de Andalucía, awarded via competitive tender processes, supplemented by direct B2B relationships with private sector clients in hospitality and healthcare. GTM is sales-led through public tender, with supplementary commercial relationships and international exploration (Mexico via ICEX forums). The company invested approximately 3 million euros in 2025 on fleet renewal and digitization, and 4 million euros in biosanitary plant modernization in the prior year, signaling a capex-intensive phase tied to its Sustainability Strategy 2025-2030. As of mid-2026 the company employs 101-250 staff and operates under CEO Pedro Caraballo Bello, with new Technical and Strategy Director (Álvaro Barco Castro) and Operations Director (Natalia Macías Martín) appointments made to execute the strategic plan.
