A large part of our environmental impact comes from our wastewater, mainly with organic oxygen-consuming substances and phosphorus. The wastewater goes to our own wastewater treatment plant in Ingvallsbenning where it is purified by a membrane bioreactor before it reaches a lake. Our work focuses on constantly reducing this burden, mainly by reducing wastage in production. This may be possible due to changes in work procedures and staff education.
Oppigårds care about the local food production, therefore we can proudly say that a large proportion of our byproducts from our production is used as animal feed for farmers in the region. Spent grains consisting of malt residues from mashing, becomes food for dairy cows, whereas the yeast, hops and hot brake (a protein precipitate from the brewing process) becomes prime pig food.
- about 20 tons of spent grain a week
- perfect feed for cows
- 20 000 liter a week
- yeast and beer
- contains enough proteins to cover the dayily intake.
The water used to cool the wort is being heated through the process and we then reuse that water for the next brew.
We also recycle the steam from boiling the wort to heat our dishwater. The farm where our family owned brewery is located has been in the same family for almost 300 years and we intend to keep it that way for many more to come.
We are also running our own waste water treatment plant. All waste water go thorugh the proscess and get cleaned to drinking level.
