Since 2010 Swish has collected and sorted its own cardboard, paper, polythene, wood and metal waste. The remaining general (unsorted) waste is collected by Swish’s waste processing partner Briers.
All of the sorted and unsorted waste is reprocessed by Briers and a report supplied to Swish on a monthly basis showing the outcome of the sorting process.
Since 2010 no waste has gone directly from the Swish site to landfill.
Swish reports its waste figures in two forms. In overall terms during 2014 the following waste was collected and processed:
| Waste Type | 2013 to 2014 % change normalised per production tonne | 2008 to 2014 % change normalised per production tonne | 2015 Target | Comments |
| Production & office waste (primarily card, poly, paper, wood and metal). | 21.3% | 113.7% | Maintain | The amount of clean waste diverted from the General Waste stream and pre-sorted by Swish on site continues to grow. Eventually this figure should stabilise |
| General waste (unsorted) | -51% | -50.70% | -10% | In 2014 the general waste figure grew as the company absorbed new production facilities into its systems. General waste generation is now back under control. |
Swish is a highly efficient manufacturer that creates little waste. Any manufacturing waste that is generated, including saw dust from in line saws, is recycled back into the production process.
Waste from raw material transportation and storage is minimised by the use of silo storage and supplier control of the material levels in those silos.
