Synergie Environ was commissioned by Envirowise to carry out a study at The Scottish Salmon Company’s Cairndow site. This is one of a number of sites around Scotland operated by the company and processes 16,000 tonnes of salmon per year which accounts for 73% of the company’s total production of 22,000 tonnes. The Scottish Salmon Company itself accounts for approximately 20% of Scotland’s salmon production volumes. A detailed site survey was carried out in partnership with The Scottish Salmon Company’s staff, to investigate the total cost of waste and water management at the site and make recommendations to improve the efficiency with which water and raw materials are used

The survey was supported by the collation and analysis of extensive billing and production data to identify the tonnage of fish processed as well as water consumption to make specific recommendations for improvement. Key findings included opportunities to reduce water consumption, flow rate restrictors and fittings with alternative spray patterns to hoses used for fish washing, urinal flush controllers, WC cistern volume reducers and aerator heads to the hand washing station outside the production area.  

In total, the review identified total potential cost savings of over £48,000 per annum. The associated potential environmental benefits included waste tonnage savings of over 10 tonnes per annum and water savings of over 16,700 m3 per annum. It is recommended that the existing cleaning processes are reviewed and the possibility to reduce water and detergent consumption is investigated. To achieve this will require continued awareness raising of staff. Whilst many of the recommendations made in the project were relatively low cost, tax allowances are available to support the purchase of specific water saving equipment.
