How about applying the Zero Waste Event guidelines to the OSCE Days in Berlin and ideally in all cities?
Festivals and conferences create an insane amount of waste. It's important
ensure that during the 5 days we will actually make our best to reduce the amont of solid waste, and raise awarness on site.
Waste reduction can be applied to differents aspects of the organisation (material used during workshops, catering, communication ...)
We can brainstorm together to identify for each aspects how can we reduce the amount of waste and the alternative that be implemented as substitute.
Here there are already some useful and easy to implement tipps:
Create a Zero Waste Event Guideline
it can be published in severals languages on the OSCE days website, sent in the newsletters and sent as reminder with the participants confirmation
Provide only reusable plates and cups
Plan in advance the number of participant to manage food supply accordingly to minimise food left overs
Limit flyers, billboard, and encourage our partners to do so
Create userfriendly signages for waste sorting
Find local partner for waste recovery
Organise a material library during the event
Organisation on site / logistic
Rental of furniture and technical equipment
Collect used badges from participants
Make sure to transform materials from the OSCE days into materials for future events.
Elaborate a waste reporting to track waste flow and measure the improvements
(this can be part of the documentation work after the event)
