oscedays twitter white

The first Open Source Circular Economy Days (OSCEdays) happened from June 11th – 15th 2015.

33 cities from 25 countries were involved with local events across the globe discussing, sharing and prototyping an Open Source based Circular Economy.

Naturally, for the way this event was created, there are two types of documentations:


I. IMPRESSIONS & OUTCOMES:  Below you’ll find impressions mostly in the form of links to videos, images, forum topics and documents – a list. There is a mirror of it in the forum where things always can be added.

II. OSCEdays: OPEN SOURCE: The whole event was developed using open source methodology itself, a complete transparent and open workflow. Start with the global OSCEdays READ ME FIRST. – And here is a recipe on: How to develop global OSCEdays15 – A Timeline of Tasks

Future List

OSCE FUTURE LIST – By listening to the global OSCEdays community in 2015 we could distill a future wish list for an OSCE, to tackle together.

rhizom stage

Founding Meeting

OSCE ASSOCIATION – With the success of OSCEdays 2015 the energy was there to build an association to foster OSCE beyond an annually global event.




Live City Video Interviews.

The Global Reporting Team made live-streamed interviews with 24 cities during the event. The videos differ in quality, a lot suffer from instable wifi-connections. There is value in all of them! We point 6 out to you (marked with (*)). Those (also) combine the criteria: stable connection/video, inspiring or surprising thoughts about Open Source & Circular Economy and sparkling enthusiasm for the OSCEdays community and the future of it.°


Video Messages From Experts

We had prerecorded video messages from experts sent to the OSCEdays community. Each day one was published in the Blog. And they are still very highly recommended – videos made to watch!°

Streamed Talks & Roundtables

We had a live-streamed talks with high-level experts from all over the world, mostly thanks to Gien Varney Wong the local organizer in Cape Town who collected and organized most of this talks in his OSCEdays Cape-Town-Channel. (Gien is in the 3 picture from the left interviewing people.)°


I have seen much more video scrolling by during and after the event. Anything that should be added? Share the links or files here.°


Reports from after & before

Working on Challenges is the center of the OSCEdays 2015. And documenting is key. The forum we set up for the OSCEdays allows to share challenges and collaborate on them publicly. Over time an ongoing body of knowledge can be built and connect a global community. For the first edition of the OSCEdays the forum came late, we switched it on 2 months before the event. For many local organizers this was a bit late. So not all published their challenges in the forum. But till today (June 21, 2015) 102 challenges are published in the forum coming from over 10 cities in 4+ languages. Follow the Challenge tag!

#OSCEdays @Twitter

Looking at the hashtag #OSCEdays on Twitter during the days was a quite exciting experience! Tweets with all kinds of interesting statements, images and incredible enthusiasm coming from all over the world. Awesome! How to filter tweets to present here without having a too subjective choice? Maybe we’ll come up with a solution soon 🙂

Liked what you see? Setting up a global event and organizing a global community consumes a lot of resources – for hosting, communication and so on – and needs a lot of time. If you donate to the project we can make sure it continues and can become even stronger! Thank you.
