Sustainability
Rye River Brewing Co. has been making big strides towards becoming a more sustainable brewery. Established in 2013, Rye River Brewing Company is based in Celbridge, Co. Kildare, and we’re known for producing award-winning craft beers, focusing on quality and innovation, with a commitment to sustainable brewing practices.
Reverse Osmosis
Meet the MVP behind every single RRBC beer: our brand-new Reverse Osmosis system! Custom made for us by our amazing neighbours Veolia, this upgraded filtration system boasts three times the output of our previous setup, allowing us to keep up with demand while still dialling in a unique water profile for each style of beer. Beer is at least 90% water, so it better be top-notch! Since 2018, we’ve reduced our annual water consumption rate by 26.21%, and now, with this state-of-the-art system, we’re taking things to the next level. Who knew water could be so thrilling?
Malt Bags and Silo
More brewing means more malt! To reduce waste, we’ve invested in a malt silo that, while too massive for our video, can store all our Pale Malt! Now, 26 tons of malt is delivered directly into the silo at a time, cutting out 1,040 plastic grain bags. Plus, we now get our Pilsner, Wheat, Vienna and Munich Malts in 1 ton bags instead of 25kg bags. This all means less deliveries, less plastic bags in the bin and less lifting for the brewers! ♻️🍺
Efficient Brewkit
Our new 100hL brew house isn’t just big and shiny, it’s efficient! We’re getting up to 98% extract recovery from our malt, which means more beer, less waste and that same first-rate RRBC quality. Sláinte! 🍻🌾
Spent Grain
100% of our spent grain goes straight to a local farmer to be used as animal feed. Zero waste = 100 wins for us, the farmer, and the planet! 🌎 Cheers to that! 🍻
Gas Consumption
Over the years, we’ve taken small but impactful steps to reduce our gas consumption. By upgrading to a more efficient boiler, carefully monitoring steam traps, and recapturing heat from our boiled wort to warm water for future brews, we’re improving efficiency and seeing real results! Since 2018, we’ve cut our annual gas usage by 16.28%. 🎉 If you need us, we’ll be clinking glasses over our weekly meter readings. 🍻🌍
Natural Lighting Optimisation
Sunny days might be rare in Ireland, but we’re busy optimising natural lighting around the brewery, and swapping out warehouse lights for LEDs when needed. They sound like small steps, but we’ve cut our electricity usage by 15.06% since 2018. The electricity we do use? It’s 100% renewable. ⚡️
Repak
Over the past few years, we’ve been refining our sustainability and recycling approach with the support of Repak. 
Members since 2019, we’re happy to support their recycling and sustainability goals, and we’ve even reduced our physical waste by 70% since 2018.
