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 2017 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.
Grolsch is also committed to sustainability in transport and logistics. In the past financial year, we sent 92.5 percent of all our container exports to Africa / United States / Canada via inland shipping to Rotterdam. The choice of inland waterways instead of road transport means significantly less CO2 emissions. Grolsch seeks to emphasize the advantages of inland shipping among customers and carriers. By using inland navigation with a 40-45 ft. sea container, we save 71,2% CO2, compared to road transport.
Together with other large Twente companies, Grolsch signed the Better Use of Twente Canals deal (‘Beter Benutten Twente Kanalen’). The objective is to transport more freight by water. If all goes well, this will mean 900 fewer lorries on the road every day by 2020.
At Grolsch we are undertaking a variety of initiatives and activities to reduce energy use and CO₂ emissions:
