The context

Plastic caps from empty bottles, yogurt, and milk packages often end up in general waste bins, even though they're easily recycled for reuse. These caps have long been used as a way for people with disabilities to collect resources for the purchase of essential items.


we had to communicate to the public that even a small bottle cap can be priceless to people with disabilities and the environment. "A small cap can be a big help" was chosen as the slogan of the campaign. Based on this slogan, we decided to create the largest mosaic from discarded bottle caps in the world.

The bottle cap
collection campaign

Before the main event of the campaign, we prepared a mini-campaign, which called on the public to assist in the collection of bottle caps in designated buckets placed at major retail centers and other locations in the country. This allowed us to collect over 500,000 bottle caps which we were going to use to build our mosaic in only 2 months.

Color separation of caps

In order to effectively use the bottle caps to create a mosaic and make sure we had the needed quantity of caps, so that we would not run out in mid-build, we needed to separate the collected caps into color groups. The retirement home in Hrastnik helped us out and separated all the caps into color groups.


We assembled the mosaic in the parking lot of BTC, in front of the Crystal Palace office building. More than 120 elementary school, university students, and volunteers had a plan to assemble the mosaic in 48 hours and qualify for the Guinness Book of Records.

We also invited a graphic technology engineer, who prepared a cutout template in the size of 600m2, onto which the caps were being applied. We had to glue the caps with a material that doesn't leave traces so that the caps could be recycled after the campaign ended. The mosaic assembly was communicated as an event, with guest appearances by musicians Alya, Hamo, and Tribute2love and other accompanying entertainment.

Communication materials

The motif of the mosaic was used on posters, advertisements and digital banner ads.

Social media management

The cap collection campaign was covered on the largest evening news program in the country, as well as media such as Siol, Žurnal, and other news outlets. The participants of the broader event used their own social media channels to communicate about the campaign with their followers.

During the build itself, we recorded a web video and communicated with the public through the event Facebook page. The highly profiled portal Trend Hunter published our video and placed it among the top 3 most innovative environmental campaigns of the year.

The charity auction
and donation

We asked the Slovenian photographer Aljoša Rebolj to photograph the mosaic for the purpose of an auction. We would invite local companies to bid on the photographs, and the auction proceeds were donated to three families in need.
