How to reduce the environmental impact of production processes by keeping high efficiency levels?

By means of the study and ongoing application of solutions that can be seamlessly integrated into our production processes to improve environmental impact

We focus on ensuring that our Cermenate and Quimper plants, ranked among the leaders in Europe for production capacity, are also considered best practices in relation to the reduction of environmental impacts.

Our production plants are ISO 14001 certified and our commitment, outlined in our Environmental Policy, is targeted at improving impacts. In particular, it focuses on greenhouse gases, energy and water consumption, the production and recycling of waste and the materials used for the packaging of our products.

Emission management

Over the past four years, in addition to paying particular attention to the issue of controlling greenhouse emissions both at our production plants and in our offices, we have focused on the emissions caused by fishing fleets working for Saupiquet in France.

Saupiquet owns three Purse Seiner vessels, which fly the French flag and fish tuna in the Atlantic Ocean. Every year, a certification body issues a conformity certificate for each vessel based on respect for the criteria outlined in this certificate: prevention from atmospheric pollution, from hydrocarbons and waste water.

We are also committed to reducing gas emissions produced during the transportation and distribution of finished products.

  • Increased efficiency thanks to full-load transport and programmed deliveries
  • Supply chain collaboration with co-trucking systems, which consist of transporting our goods with those of other companies and the use of vehicles boasting a 15% higher load capacity than conventional trucks
  • Modernization of vehicles, by asking to our suppliers to endorse the use of green vehicles such as Euro 5 and 6 vehicles

Energy consumption

The consumption of electric energy at our plants is closely connected to daily production volumes, to the use of production techniques and to climate conditions, meaning that the energy efficiency process is ongoing.

Since 2011, the Cermenate plant has sourced 100% of its electric energy - mainly hydroelectric energy - from renewable sources. Over the next few years, the same procurement policy will also be extended to the Quimper plant.

** This data does not include consumption in 2014 at Bolton Alimentari’s headquarters in Milan or the French headquarters of Courbevoie, where its offices are located. However, this data represents a minimum fraction compared to plant consumption.

Water consumption

Our water consumption is related to the defrosting and sterilization of our fillets and to the functioning and cleaning of our plants. Over the past four years, production line efficiency has resulted in a 10% reduction of water consumption per ton of product produced, decreasing from 13.91 m3/ton to 11.82 m3/ton.

Waste water is treated by means of special plants located inside the factory. Once purified, in the case of the Cermenate plant, the water is re-introduced into the area’s water basin, while in the case of Quimper, it is re-introduced into the urban water network. In the latter case, prior to being assimilated, the water is pre-treated at the Quimper wastewater treatment facility.

Waste management

Bolton Food is renowned for its meticulous waste management process. In 2017, approximately 99% of the 7,305 tons of waste produced by the Cermenate and Quimper plants and the Saupiquet fleet were recovered and recycled at authorized plants. In particular, waste related to the packaging used for production purposes including paper, cardboard, plastic, wood and metals are all earmarked for recycling or re-use.

Packaging sustainability

For the packaging of our finished products we mainly use cardboard, tinplate and aluminum. In keeping with the increase of production volumes, over the past few years, consumption of these raw materials has increased, as has the percentage of raw materials originating from recycled materials.



Type of packagingPercentage of recycled raw materials (2017)
Main materialsPaper and cardboard81%
Materials used marginallyWood0%

In collaboration with our suppliers, we have worked towards increasing the recyclability of these materials.

Over the past two years, activities aimed at reducing the thickness of packaging materials have permitted us to save a total of approximately 290 tons of aluminium and tinplate, equal to the weight of approximately 240 utilitarian vehicles.

Product packaging is the most immediate medium to convey information on which consumers’ purchasing decisions are often based.

For this reason, we are committed to using our packaging to convey clear and correct information regarding the ingredients contained in our products and their nutritional properties. In 2018, we will start introducing information about fishing oceans, the FAO area and fishing methods on the packaging of all our products. At present, this information is only accessible by filing a request for traceability on our websites.
