Comparative study of 3 products
The first step in the study was to determine what exactly is meant by the term ‘capital goods’. A practical definition is chosen: capital goods are all goods with a useful life of more than one year, such as machinery, instruments and buildings, that are used during the life cycle of a product. Everything that is used for less than one year, such as fertilisers, diesel, natural gas, pesticides and substrate, are considered as ‘operational inputs’, also qualified as consumables.
To obtain a picture of the contribution of these capital goods on LCA results, Mike is carrying out a comparative study of 3 products (strawberries, milk and cereals) using a model with and without capital goods included. To keep the study manageable its scope is restricted to capital goods used on the farm.
