CO2 and waste

Decrease our CO₂ emissions and maximise the reuse of waste

Our Vision and Ambitions

The demonstrable change in the climate caused by man, coupled with the long-term prospect of fossil fuel shortages and the resulting price implications, are all important reasons for Grolsch to substantially improve its energy efficiency and make sharp cuts in CO2 emissions. Our wastewater purification produces a great deal of biogas. In that way Grolsch generates 18% of its total energy needs itself. Grolsch's target for F16 is to further reduce CO2 emissions to 5.28 kg per hl beer.

Regarding waste Grolsch ambition is to reuse waste as much as possible. No less than 99.8% of the 14,171.5 tonnes of waste is reused! For example the brewers grains that are released during brewing are sold to farmers throughout the Netherlands as animal feed, yeast is reused in the pharmaceutical industry and our labels are reused in the brick industry.


Sustainability is also key for packaging that Grolsch designs. We use lightweight packaging and ensure that bottles are reused. No less than 15,000 tonnes of our old pilsner bottles were reused last year. We also encourage recycling, which saves raw materials and is less damaging to the environment.

When it comes to our CO₂ footprint, we look beyond our core business. We work together closely with our partners to make transport as efficient as possible.


Our Activities
At Grolsch we are undertaking a variety of initiatives and activities to reduce energy use and CO₂ emissions:

  • Projects for improving energy-efficiency in the supply chain (production and filling);
  • Optimising heating and lighting at our premises;
  • Increasing our level of biogas (green energy) produced by our wastewater purification system;
  • Encouraging careful use of energy by employees;
  • Economical use of raw materials, consumables and packaging materials.
  • A returns system for bottles/crates;
  • Drawing up a Life-cycle Analysis for all packaging, to establish its impact on the environment;
  • Reusing 99% of by-products and waste;
  • Use of bio cups at events.
  • Use of plastic pallets;
  • Use of lightweight bottle caps.
