WHEN CREATIVITY AND SUSTAINABILITY MEET THE ART OF BREWING, A CIRCULAR BEER DOESN’T LOOK THAT FAR ANYMORE…
Commodity producers should aim to “do more and better with less”. This is the motto of the 2015 United Nations summit, in which all countries took responsibility to protect the planet by sustainably producing products and strategically managing natural resources. With 1/3 of produced food wasted every year and the resulting loss of prime resources, the regeneration of the food system is one of the most relevant topics highlighted in the agreement.
Today, we want to take a look at the latest sustainable developments in the world of brewing. May beer be the most widespread and loved beverage in the world, but the current beer production system is not environmentally friendly. To produce one liter of this refreshing drink, it takes between 30 to 90 liters of water, which is ultimately discarded together with draff and dregs. Nevertheless, these scraps, which make up about 90% of total used raw materials, preserve properties that can be of use for other industries. Biogas factories and biorefineries already use them for the production of renewable energy, compost, and organic substrate. Nonetheless, all over the world, we could observe the rising of creative initiatives trying to make brewing a more sustainable economic activity.
