| Résumé : |
It is false to believe that manufacturing anything results in zero waste - unless by "zero" what you mean is when the waste can enter something called its end-of-waste cycle. These waste products can be modified by producers into valuable co-products (non-determining in the case of leather). Likewise, a company cutting car seats and trim could develop the mentality that there is the main leather cut part product and then the cutting co-products (which will also be non-determining).
This is the mentality of companies that are using the geometrisation of leather as a process design focused way of seeing the cattle hide in two parts - the leather main product and its by-products ; another name for non-determining co-product. Geometrisation, such as Kind Leather from JBS Couros for example, removes leather by-products as early in the process as possible, before they have changed into a form that determines how producers can use them.
Geometrisation is the design of a process that tries to maximise profit from all the input mass entering a cycle. Trimmings constitute a significant part of the process, with typically a tannery processing from raw to finished producing a little more than 10% - 129kg trimmings out of 1100 kgs of unsalted hide. A tannery geometrising will negate that downstream trimming by-product and those trimmings can enter the food industry as a co-product - increasing value. |
