Transition Minett asbl has announced the launch of the first "made in Luxembourg" waste fresco, entitled "Game of Waste - Le Tri-logie".
How should electrical waste be sorted? Should a broken appliance be thrown away or recycled? What happens to waste made of several materials, such as wood mixed with plastic? Where do non-rechargeable batteries end up? And which bag should be used for medicine packaging?
These are some of the everyday questions addressed by participants at the official launch of Luxembourg's first waste fresco on Wednesday 10 December 2025 at Facilitec, the circular economy hub in Esch-sur-Alzette.
Developed with the support of the Œuvre Nationale de Secours Grande-Duchesse Charlotte and the City of Esch-sur-Alzette, Game of Waste - Le Tri-logie takes the form of a collaborative group game. It aims to helps the general public better understand waste management systems in Luxembourg and adopt practices that encourage waste reduction.
The idea for the game emerged during the 2023 "Assises du Climat", within the Citizens' Climate Collective (Collectif Citoyen pour le Climat - CCC) "Zero Déchet".
With support from Transition Minett, the collective drew inspiration from the French "fresque des déchets", adapting it to Luxembourg-specific data and local waste management structures. This approach was further enriched by site visits, notably to SIVEC and Minett Kompost.
According to Transition Minett, the project represented "a true human adventure", mobilising motivated citizens who are now jointly responsible for the development of the game.
The main objective of Game of Waste - Le Tri-logie is to raise awareness and educate the public about the real impact of waste, while emphasising that even recycling is never environmentally neutral.
The game is based on three educational objectives: understanding the end-of-life cycle of products once they are thrown away; becoming aware of the environmental issues linked to waste production and management; and co-creating individual and collective solutions to reduce waste.
Participants select a product type from four categories (food, packaging, single-use or long-lasting) and then work together to reconstruct its journey, from disposal in rubbish bins, through processing to environmental impact. While the full version of the game lasts between two and three hours, a shorter one-hour version was presented at the launch.
The fresco concludes with a collective reflection phase that generates concrete ideas, inspired by the Zero Waste "5 R" principles (refuse, reduce, repair or reuse, recycle and return to the earth): buy second-hand; repair items at repair cafés and sewing workshops; use reusable containers; buy in bulk; pool, lend and share resources.
The game is currently available in three languages: French, Luxembourgish and English.
In 2026, the project is set to expand further, with plans for open-source availability on the Transition Minett website, as well as distribution of complete game kits (cards, facilitator's guide, materials) through partner organisations, and development of a network of trained organisations capable of passing on this knowledge to their own audiences.
Any individual or organisation wishing to become a facilitator can do so after completing a training course, currently led by Jeanne, head of the Zero Waste project at Transition Minett, alongside the citizens who co-created the fresco. Demonstrations can already be organised at Facilitec on request via email: jeanne@transition-minett.lu.
Transition Minett is inviting interested associations, schools, businesses, institutions and citizens to discover this interactive and educational tool.
