DOI: http://dx.doi.org/10.1065/lca2001.12.069 --- A Life Cycle Assessment (LCA) was carried out for
milk production extending from the origin of the inputs to the
agricultural step to the consumer phase and the waste management
of the packaging. Three Norwegian dairies of different
sizes and degree of automation were studied. The main objectives
were to find any hot spots in the life cycle of milk, to determine
the significance of the dairy size and degree of automation,
and to study the influence of transport. The agriculture
was found to be the main hot spot for almost all the environmental
themes studied, although the dairy processing, packaging,
consumer phase and waste management were also of importance.
The consumer phase was the main contributor to
photo-oxidant formation and important regarding eutrophication.
The small dairy was found to have a greater environmental
impact than the middle-sized and the largest dairies. The
transport did not have any major influence. | | Keywords: consumer; dairy; dairy processing; detergents; distribution; industrial milk production; LCA; life cycle assessment (LCA); milk; milk farming; milk packaging; milk production; packaging; transport; waste management |
