The Trescases commitment

The carbon footprint

The Bilan Carbone TM (carbon footprint) study was conducted by Cairn Environnement, an independent consulting and engineering firm specializing in the environment, located in Perpignan in the Pyrénées Orientales region of France, through the FFSL (French Federation of Cork Unions).
This study is based on the Bilan CarboneTM, a methodology developed by the French Agency for Environment and Energy Management (ADEME).
It is used to analyze and measure the greenhouse gas (GHG) emissions of a company and its activity.
The carbon footprint calculation for Trescases corks measures direct and indirect greenhouse gas emissions from the Le Boulou plant.
The parameters taken into account are:
  • The stages of the production of cork (from lifting in the cork oak forest to the production of semi-finished corks shipped throughout France)
  • The upstream freight (corks, related products, packaging)
  • Manufacturing related products
  • Manufacturing and packaging end-of-life
  • The energy consumed on site and internal refrigerant emissions
  • The energy consumed on subcontractor sites
  • People travelling (commuting and business travel)
  • Management of direct on-site waste
  • Delivery to customers
  • End-of-life of the corks


Stages of cork production: 5.5 g CO2 eq per unit estimated.
Trescases plant Le Boulou carbon footprint 5.4 g CO2 eq per unit.
End-of-life of corks: - 2.7 g CO2 eq per unit.
Carbon footprint for the Bouchons Trescases site at Le Boulou:
5.4 - 2.7 = 2.7 g CO2 eq per unit.
Total Bouchons Trescases Carbon footprint for the entire
cork manufacturing process:
5.5 +2.7 = 8.2 g CO2 eq per unit.


The carbon footprint for "natural cork stoppers" and especially that of Bouchons Trescases is the lowest of all closure solutions for still wines. This is due to good control of the process on the Le Boulou site.



  • Continuous optimization of manufacturing processes to reduce energy consumption and waste production.
  • Installation of solar panels for electricity generation
  • Environmental approach according to ISO 14001.



Energy: Solar panels
Modification to the roof of the storage sheds with an area of 3,200 m², removing the old fibre cement roof, fitting a new steel roof and photovoltaic solar panels with a surface of 1,000 sqm on the south-facing slopes.
This facility will provide us with better energy management and very significantly improve our carbon footprint.
Electricity production in 2010: 28,431 Kw/h
2011 : 28 124 Kw/h
2012 : 28,327 Kw/h
Changes to the cooling system of the cork packaging machine and a branding machine with a closed-loop cooling system (like a radiator), resulting in significant savings in water consumption.

To make natural cork closures, Trescases does not emit any volatile organic compounds (VOC).
In 2007, a study of the carbon footprint was conducted by Cairn Environnement on our site at Le Boulou.
Carbon footprint of the Trescases plant: 7.0 g of C0 ² per unit.
The carbon footprint of Bouchons Trescases is the lowest of all closure solutions for still wines. This is due to good control of the process on the Le Boulou site.


Value chain of cork:
Corks discarded during our manufacturing process are sent to a factory to be incorporated into other applications with high added value (e.g. insulation).
So with cork, nothing is wasted and no waste is generated. Nothing is lost and everything is made use of.
Use of recycled materials:
In addition to the complete recycling of cork, preference is given to recyclable materials, whenever this option is viable.

Bouchons Trescases has set up a Waste Management Environment procedure, consisting of reducing the volume of packaging.
All waste from running the plant is sorted: cardboard, plastic, empty plastic containers, pallets... Office waste: used printer cartridges, batteries, small cardboard boxes, paper, etc.
This improved waste sorting management meant that we were able to make significant savings in 2012 as compared to 2011 for the item "waste dumped": lower by 14.28%.

Acquisition of a second laser marker to maximize productivity and to improve the quality of marking for smaller orders.
Acquisition of a 3D-view machine for sorting and lining up cork tops and bottoms (a Trescases prototype): automated marking station on a single end.
As part of ongoing HACCP actions and attention to maintaining hygiene, we have thoroughly cleaned the marking room and the surface treatment hall.
Purchase of a fast counting machine (400,000 corks / hour) with a feeder belt. The feeder belt of the small packaging unit has been replaced.
Implementation of 25 programmes on the surface treatment programming units and full electrical overhaul of the surface treatment machinery.
(Investment: 10,000 € excl. tax).


Bouchons Trescases have identified all risks by activity and have implemented control measures as follows:
Human risk: associated with manual and mechanical handling:
Limiting the carrying of weights by creating storage racks, determining traffic areas and wearing safety shoes and clothes.
Fire risk: extinguishers and smoke hatches checked annually, personnel evacuation plan, staff fire drill.
Electrical risk: annual inspection of electrical installations, accreditation for the maintenance manager, cabinets are locked.
Transportation risk on the site: the safety protocol for loading and unloading is issued to all of our carriers.


November 2012: The five employee first-aid and rescuer workers did training to maintain and update their skills, and five other employees received initial training in first-aid and rescue work.
The entire staff is trained annually and daily vigilance is required for compliance with health and safety practices in accordance with our established HACCP system.
All staff are trained in the use of fire extinguishers and those who drive power trucks have a driving accreditation (CACES) that is monitored and updated.


For many years, Bouchons Trescases have had a quality management process:

  • Certification of compliance with the International Code of Cork Stopper Manufacturing Practice (5th Edition) SYSTECODE. Since 2012, Bouchons Trescases has had SYSTECODE PREMIUM accreditation.
  • Certification according to the guidelines of the EC-Cork; audit guide of the Analysis System for Hazard Critical Control Points (HACCP) in the cork industry.
  • Only for our corks sold as "FSC Pure": Control System for FSC wood products in accordance with the Forest Stewardship Council system of certification.
