KNOCK . OUT . BUDDY

The Recycling of Used Coffee Grounds

ABOUT

With a very welcome rise in the awareness of the need to recycle and repurpose used coffee grounds from thousands of coffee outlets around the globe, it is becoming a more common practice to offer the coffee grounds back to the consumer, to be taken home and used in their own gardens. There are also a growing number of other more commercial schemes that look to recover the used coffee grounds from coffee shops to reprocess into new products such as soil conditioners, biomass fuel, bio diesel, flavourings, oils, mushroom substrate, essences, stains and many other products besides.

The PURPOSE

& The PRODUCT

The Knock Out Buddy is a simple mechanical device by design to enable the discharge of used coffee waste from the portafilter (handle of an espresso machine) into a ‘coffee bag’ in a coffee shop style environment whilst simultaneously enabling specific advertising space and opportunity. The purpose of this gadget is to enable the operator the ability to offer used coffee grounds to their customers to take home (for use in their own gardens), or to return the used coffee grounds neatly in a sealed bag to a re-processor of used coffee grounds

"

Currently the majority of coffee houses use a "Knock out drawer", usually situated under the grinder, which has a bar for knocking the portafilter onto. When this drawer is filled up, or at the end of the day, the operator will then be required to empty the drawer into other containers or bags to enable storage of the product until collection.

This process can be time consuming and messy if trying to put the grounds into smaller bags for the consumer to take away.

We considered that one of the best ways to store the used coffee grounds (UCG) was in the original package it arrives in. The majority of coffee shops receive their coffee beans in 1kg foil lined bags fitted with degassing valves.

We realise that if we are to expect the coffee houses to use these bags to store the UCG in, we needed to make it super easy and efficient to get the grounds back into the bags.

Taking the process back to the beginning, we thought why don't we discharge the UCG directly into the bags that the beans arrived in.

The DESIGN

We spent time designing and prototyping a number of different methods of discharging the coffee directly back into the freshly opened coffee bags. Our designs had revolved around the principle of attaching the bag to a stand with an integrated knock bar, this presented a number of issues of stability and size of footprint.

The "eureka" moment occurred when we were trying to overcome one of our design briefs, which was to ensure the empty bag continued to display the coffees brand during its secondary purpose of collecting the UCG, we considered putting the knock out 'gadget' INSIDE the bag!

Very quickly, this proved to be the perfect solution to all the different key areas of the design brief, and the Knock Out Buddy was born!
