Proiektu honen asmoa da Bilboko Ingeniaritza Eskolako tailer mekanikoan eta Zamudioko instalazio berrietan kokatutako Fabrikazio Aeronautiko Aurreratuko Zentroan egiten diren mekanizazio prozesuek ingurumenean duten inpaktua murriztea. Horretarako, helburu nagusitzat proposatzen da oraingo olio-emultsioen ordez (taladrinak deitu ohi zaienak), makina-erremintek ebaketa-likido gisa erabiliak, hozte kriogenikoa erabiltzea, ingurumenaren, osasungarritasunaren, garbitasunaren eta ekonomiaren ikuspegitik instalazioen eraginkortasuna areagotzearren.
