Environmental performance of a Portuguese mature cheese-making dairy mill

Improvement alternatives for the environmental key factors within the limits of the dairy factory were proposed based on a reduction of energy consumption, the use of a more environmentally friendly fuel in the boilers and the use of new trucks with lower exhaust emissions. According to the results, it has been demonstrated that it should be possible to slightly reduce the environmental profile in some impact categories (acidification, eutrophication, global warming and photo-oxidants formation) without involving significant economic investment.
