1. Brewing with 100% unmalted barley reduces climate impact and improves land utilizationNovozymes Ondea® Brewing Life cycle assessment documenting 8% reduction in greenhouse gas emissions and 7% improved land utilization
2. 17/11/2009 2 Beer has traditionally been produced from malted barleyWith Ondea Pro, great beer can be produced from un-malted barley Avoiding malting reduces CO2 emissions and barley losses Barley Brewing with Novozymes Ondea® Pro reduces environmental impact Greenhouse gas emissions can be reduced with 8% and 7% less land is required to produce a hectoliter of beer.

Hinweis der Redaktion
LCA is about comparing the environmental impacts of two or more alternative ways of delivering the same product.In the following, we have analysed and compared the changes that occur when Ondea Pro is used in production of one hectorliter of beer (100 liters) and malting is avoided.
