Cuddly toys and colorful bins: Festivals are a test-bed for sustainability
The traditional Hanse Sail festival in Rostock has set all sails – and Clean is on deck scouting for sustainable innovation.
Through the STRIVE-project, Clean supports sustainable initiatives during Hanse Sail and other events marked by a strong tourist presence.
Clean is the lead on the project, and for us it’s really nice to have a lead that has so much knowledge in making new projects and who has a big platform. – Janika Ballhöfer, Project Manager, Plastikfreie Stadt
My first circular economy
One concept, realised by the Plastic-Free City Initiative, turns waste collection into a can-tossing game with cuddly toy prizes.
Closing a child-sized loop of ownership, families can donate their own pre-loved toys. The toys are then thoroughly cleaned and put up as prize rewards for others.
It’s no accident that STRIVE pioneers new projects at an event like Hanse Sail.
This is an opportunity to test innovative solutions, and festivals are the best platform for that, because they are a kind of creative labs. – Janika Ballhöfer, Project Manager, Plastikfreie Stadt
Supporting sorting
Another project involves experimental bins. Using intuitive combinations of shape and colour, the bins are designed to improve festival-goers’ waste sorting.
15 stations sorting stations currently test the effectivenes of the recycling streams where waste is sorted into plastic, paper and residual.
Each waste item might be small, but the potential reach is massive, as the traditional sailing festival attracts hundreds of thousands of visitors every year.
The plan is to scale it up and use it so it spreads, and so it has an influence on the tourism in the city’s other areas. – Janika Ballhöfer, Project Manager, Plastikfreie Stadt
Circular sanitation
As part of the STRIVE project, Hanse Sail is also testing compost toilets from the company Finizio at the festival.
The aim is to asses user acceptance and environmental impact from the innovative solution and set up a system for recycling human waste.
Going around, coming around
The initiatives are pilot-projects testing scaleability. But STRIVE’s presence also supports a general and ongoing knowledge-exchange:
It’s about collecting best practices, it’s about learning from each other – Janika Ballhöfer, Project Manager, Plastikfreie Stadt
Through STRIVE-initiatives, the exchange of knowledge spreads to festivals such as Malmöfestivalen in Sweden and the Freedom and Solidarity Festival in Poland.
We can learn from each other. We can see how they face these challenges and struggles. – Janika Ballhöfer, Project Manager, Plastikfreie Stadt
STRIVE and Hanse Sail
Hanse Sail is Rostock’s annual maritime festival for traditional sail ships.
The festival runs from August 7-10 and attracts around 500.000 visitors, over 50 % of whom are tourists.
This year 122 traditional ships join the festival, which is spread out over 7 distinct venues.
The STRIVE project works to transform festivals into drivers for sustainable tourism in the South Baltic region.
At Hanse Sail STRIVE works with local and international sustainability innovators to share knowledge and pilot new projects.
