Why the French are fed up (and what it means for Macron)

Macron, Marine Le Pen, Bidon Hosseur, Denis Chatelain, Grégoire Courtois

Emmanuel Macron is projected to win re-election in 2022 despite facing a fragmented political landscape marked by the collapse of traditional parties and a surge in support for populist figures like Marine Le Pen and Éric Zemmour. Although his administration has delivered rising incomes and a robust post-pandemic economic recovery, three-quarters of French citizens perceive the country as being in decline due to deep-seated grievances over cost of living, immigration, and a perceived disconnect between urban prosperity and rural stagnation. A second term would make him the first French president in two decades to be re-elected, yet governing with a mandate from a fed-up population that views the mainstream options as default choices presents significant challenges for future reform.

Cash from trash: could it clean up the world?

Arthur Huang, Adriane

Amidst global waste generation reaching 2.2 billion tonnes in 2021, the event highlights MiniWiz's economic upcycling of discarded materials into high-value construction modules and the circular economy successes of Taiwan's strict waste management regulations. It contrasts these industrial and municipal innovations with individual behavioral shifts that can reduce household output by 99%, while noting that current technological advancements like the AI-driven Trashpresso address only a fraction of the crisis. Experts conclude that overcoming the dominant linear production model requires a generational shift in societal consumption habits, as only 8.6% of the global economy currently operates on circular principles.

Sustainable materials: is there a concrete solution?

Nareed, Mazamel, Chris Cheeseman, Michael Ramage

Driven by intensifying extreme weather and the construction sector's 11% share of global carbon emissions, experts are evaluating alternatives to traditional concrete such as Bettila's industrial waste-based cement, hempcrete insulation, and Cambridge University's engineered Cross-Laminated Timber. While these materials offer significant emission reductions and prefabrication efficiencies, their widespread adoption faces hurdles including scalability limits for waste-derived products, mechanical strength constraints for heavy infrastructure, and high upfront costs that conflict with homeowner budgets. As urbanization pushes the global population to 68% by 2050, consumer market pressure remains the primary catalyst for transitioning toward these lower-carbon building solutions despite persistent technical and financial barriers.

Gene editing: should you be worried?
