An innovative Kenyan company is transforming human waste into sustainable eco-fuel, offering a powerful solution to deforestation. This revolutionary fuel, made from human faeces, sawdust, and rose waste, burns twice as long as local charcoal with one-third of the emissions.

Each tonne sold saves approximately 88 trees, demonstrating how such approaches can meet energy demands, prevent pollution, and create local jobs. This initiative is highlighted as part of the #OurPlanet collaboration with the World Economic Forum, showcasing new ways to tackle climate change and restore nature.

ESA's MEliSSA project develops regenerative systems to achieve high autonomy in space, transforming crew waste into food, water, and oxygen for long-term missions. This circular system aims to upcycle waste into vital resources.

After 30 years, MEliSSA's advancements also offer significant Earth applications. Viewing cities as "spaceships" needing self-sufficiency, this framework provides a model to reuse urban waste streams as resources for food, water, and energy, accelerating the transition to a circular economy.

The question of how butterflies survive Australia's massive bushfires was answered in part by Julie Favell. Near Long Swamp in Lithgow, while putting out water for fire-affected wildlife, she witnessed common brown butterflies (Heteronympha merope) fluttering inside a moist wombat hole.

This observation suggests that natural underground shelters, offering damp and cooler conditions, provide vital refuge for some species during intense infernos.

Beyond technical design, successful product repairability hinges on creating an excellent customer experience. What kind of experience should this be? Should it evoke the pride of tinkering with an old car, the efficiency of an F1 pitstop, or the care of a beauty appointment?

Defining the right repair experience is crucial for circular business models. Understanding how to craft these experiences is key to their long-term scalability and success.
