What is Eco Roast coffee?

How are Eco Roast coffee beans made?

Used coffee grounds are an abundant, energy-rich resource that shouldn’t end up in landfill.  Eco-Roast technology harnesses this valuable resource by collecting used coffee grounds and turning them into biofuels which are used to roast the next batch of coffee.

It’s carbon-negative, sustainable, waste-negative, and the most environmentally friendly process available today.

Did you know that in the UK we consume a staggering 95 million cups of coffee every day, creating hundreds of thousands of tonnes of spent coffee grounds every year. The vast majority of this largely unused resource ends up in landfill emitting harmful greenhouse gases, including methane.

“Eco Roast delivers a positive impact on our environment using closed loop technology and a passion for great coffee for a more sustainable future”

Here’s the Eco Roast process in a simple infographic:

The Eco Roast coffee process

Step 1 – The waste coffee grounds are collected

The process starts with you and me, enjoying a delicious cup of coffee in a coffee shop – the coffee shop collects the used coffee grounds in special re-purposed collection containers issued to them by their supplier. These containers are then collected at the same time as the shop’s next delivery of freshly roasted coffee.  No more chucking them into the bin!

Step 2 – The waste coffee is dried, processed and turned into biofuel

The next stage of the process, once the grounds have been collected is to sieve out any foreign objects and dry the coffee grounds. Once there is only dried coffee with no gnarly bits in it, it’s fed into a press that forces the coffee under huge pressure through a die and this forms the biofuel logs we use for our Eco Roasters.  These look like this:

Step 3 – Let the roasting begin!

Here the magic starts all over again. The third stage of the process is roasting. Custom made Eco Roasters are used to turn the coffee biofuel logs into the heat energy necessary to roast delicious fresh coffee beans. These roasters are so energy efficient that they only use around 40 grams of biofuel logs to roast a kilogram of fresh coffee! The excess heat generated is stored in large thermal tanks and used to heat the building to keep the coffee roasters toasty when it gets frosty outside.

Step 4 – packing and dispatch, and collecting the next batch

Win-win!

Once the coffee is roasted the beans are quickly cooled and packed in valved bags to seal in their freshness. If the customer is using the waste collection service then their new batch is delivered when the old grounds are collected, giving a totally carbon-neutral coffee journey. Bonus!

Eco-roasting is not only a zero-waste process, but it actively reduces waste going to landfill meaning that the whole process is waste-negative.
