Making Coffee Better for the Environment
We recognise that we live in a world with finite resources and we want to play our full part in the global movement cutting carbon emissions from the coffee supply chain.
Some of the steps we've taken to reduce our environmental impact are big, whilst other steps are pretty small, but regardless of size we've learned that every step counts.
Greener coffee roastery and workspaces
Powered by Renewables
Our sites are powered by green electricity and we are striving to create zero waste in our worklives.
More than 80% of our team walk, cycle or use public transport to commute to work and the roastery is fitted with electric vehicle charging points.
Recycling & Restoration is in our bones
Upcycling and restoration have always been a part of the Extract Coffee Roaster history; it’s just how we approach life. For instance, a visitor to our roastery will notice that our cupping table is made from reclaimed planks and the door handles were formerly parts of the roasting equipment.
The roasters themselves are rescued from scrap and restored rather than bought brand new. Our biggest roaster, Bertha, was brought over from Bosnia. Our smaller roaster, Betty, has been with us a decade now but was made in the 1950s. In the last few years, we’ve modernised these beautiful machines to make them as efficient and environmentally sound as possible.MEET THE ROASTERS
Reducing our carbon footprint
Cutting transport miles
We receive our coffee beans by sea, not air, which keeps carbon emissions down. We are always looking for ways to make the journeys shorter and the transportation more efficient.
One example is the beans for our Half Speed low caffeine and Sugarcane Decaf coffees from Colombia. With our previous decaf, using the Swiss Water method, South-American beans were shipped to Vancouver to remove the caffeine before being sent on to the UK. We found a processor in Colombia who removes the caffeine using a bioethanol by-product from coffee instead, so we were able to connect them with one of our long term Colombian partners, La Marianela to cut out the unnecessary food miles.
We have cut the carbon emissions from our roasting operations by buying green energy to power our roastery and keep the lights on. Even though our energy source is carbon neutral, we are still taking steps to use power as efficiently as possible: we’ve tinkered with our roasters to optimise their performance, added a variable fan and upgraded the burner. They now run off just 40% of the fuel they would have used when new.
We’ve added afterburners to our roasters to eliminate VOCs (volatile organic compounds) from our emissions – meaning cleaner air for our Bristol community.
Right now, a perfect solution for coffee packaging which preserves freshness and is widely recyclable / home compostable simply doesn’t exist. So, we are making imperfect progress in the right direction, you can read more about this in our Coffee Packaging FAQs.READ MORE IN OUR COFFEE PACKAGING FAQs
Reducing coffee waste
Recycling Coffee Grinds & Chaff
When you roast coffee, you are left with a nitrogen-rich chaff – like a fine sawdust. A handful of local gardeners who take the odd sack of it off our hands for their allotment, and the rest goes to GENeco which turns it into bio-fuels.
Not only does this avoid waste ending up in landfill, the bio-fuels also replacing fossil fuels – a double win. GENeco estimate that the 3.4 tonnes of chaff they collected from us in June 2021 has displaced 2 tonnes of carbon dioxide through landfill diversion and produced enough power to charge an iPad more than 29,000 times!
Recycling Coffee Sacks
The beans are delivered to our roastery in large hessian sacks with plastic liners. The sacks are passed on to the local arts centre for community arts projects, and to a Zoo to be reused in animal enclosures. The plastic liners are re-used in the roastery as bin liners.
Reducing milk wastage
Milk wastage is a common challenge in barista training. In 2020 we a zero-waste latte art throwdown with Oatly, to highlight how much milk can be wasted in barista training.
Of course, baristas need to practice latte art, which requires more coffee and milk than anyone can drink! We train foundation level baristas to practice latte art and milk-steaming using watered-down milk or washing up liquid and water.
Milk wastage is common during service, too, but we've been making positive steps here too, working closely with machine manufacturers and testing new milk-dosing machines with cafe partners to reduce wastage during service.
Choosing better suppliers
It’s not all about the coffee: we work with tea smiths in in Somerset to make our own range of Extract Tea. They thought it was nonsense to ship it from India in tiny tea bags – instead they purchased a tea bag making machine and began bagging it themselves, allowing the leaves to be shipped to the UK with 70% less packaging.
When water boilers are required, we supply cafes with Marco Bev Eco Boilers: the steel they are made from has less embodied carbon and they are highly energy efficient. They come packaged in corrugated card instead of polystyrene too – another environmental win.
Recyclable Water Filters
We choose BWT for water filtration. These filters are made from recycled plastic and are completely recyclable too.
Locally made syrups and British sugar
For syrups and pure powders we use Bristol-based Beyond The Bean. Not only are their syrups made in Bristol, just minutes from our roastery, they're made using UK grown sugar too.
Recyclable Takeaway Cups
Our takeaway cups are recyclable in your paper recycling. We chose our Re-Earth cups because paper recycling bins are now much more commonplace in public spaces. While this is an imperfect solution solution (what if it's thrown in the wrong bin?!) we chose it because it seemed like the best chance of getting the cup in to the right waste stream overall.
