Traditional approaches centered on collection and disposal currently seem inadequate in the face of serious environmental concerns and resource scarcity. Waste management has become a focused topic to address, being introduced as a key strategy towards circular economies. The Zero Waste concept hopes to transform the way cities manage urban waste and build supportive cultures around it.
Space exploration isn’t merely a testament to human ambition or a quest for new territories and resources. Our ventures beyond Earth’s atmosphere are driven by a deeper purpose: to understand better our place in the cosmos and to pioneer innovations that can transform life on our home planet.
While venturing beyond our planet captures the imagination, the true impact of space exploration may be felt much closer to home. Public perception often frames space exploration as a distant endeavor with limited relevance to terrestrial challenges. However, this perspective overlooks the substantial contributions of space programs to our world. By driving technological innovation, expanding our scientific knowledge, and inspiring future generations, space exploration has proven to be an invaluable catalyst for addressing global issues.

Evolving urban conditions call for an evolving builtscape, and retrofits have been a key mechanism to allow buildings to adapt and respond to new needs. Amidst global environmental concerns, climate retrofits have become a popular strategy to upgrade buildings based on improved operational efficiency. Global decarbonization plans have even called for city-wide retrofits, such as in the case of London, to meet civic goals. While such upgrades significantly reduce energy consumption, they often come with a hidden cost - embodied carbon in retrofit materials and the potential for future waste.
LAVA Architects has just revealed their design for The German Pavilion at Expo 2025 Osaka. Highlighting the theme of the circular economy, the pavilion is titled “Wa! Doitsu,” translating to “Wow! Germany.” Conveying enthusiasm, The Pavilion explores concepts around circularity, showcasing the “terminological culmination of the sustainability discussion.” Focusing on returning all consumable goods to the cycle of the economy, achieving zero waste, and minimizing resource consumption, the theme is visible throughout the entire design.

The structure also provides a welcoming space for rest and contemplation.
Today, interconnected and fast-paced lifestyles, future mobility trends and constant material innovation puts pressure on a slow-moving building industry. How can architecture keep up with this trend? Following dynamic and nomadic lifestyles, architects must explore new structural systems that should be able to reach multiple locations, as well as be adaptable and reusable in the future. By applying revolutionary technology for circular, scalable components and carbon-negative buildings, UrbanBeta –a spatial innovation studio designing strategies, building concepts, predictive tools and platforms for creating transformative spaces– has developed BetaPort, a robotic construction system powered by artificial intelligence and automation.
Based on the principles of a circular economy, Urban Beta and BetaPort create a sustainable construction plan, ready to grow and change over time. The studio conceives sustainable on-demand architecture systems for flexible buildings based on a kit of parts.
Over the past year, architecture exhibitions have significantly addressed pressing global issues such as climate change, resource scarcity, and social advocacy. According to the Harvard Graduate School of Design, architecture exhibitions can foster dynamic engagement with contemporary issues, serving as platforms for experimentation and critique. These events, such as the Venice Architecture Biennale, Sharjah Architecture Triennial, Milan Design Week, and Concéntrico, serve as essential platforms for creatives to showcase and explore new ideas. Moreover, they have been instrumental in addressing the urgent challenges posed by the climate crisis by promoting sustainable practices.
In 2020, in the midst of the first wave of lockdowns due to the pandemic, the municipality of Amsterdam announced its strategy for recovering from this crisis by embracing the concept of the “Doughnut Economy.” The model is developed by British economist Kate Raworth and popularized through her book, “Doughnut Economics: Seven Ways to Think Like a 21st-Century Economist”, released in 2017. Here, she argues that the true purpose of economics does not have to equal growth. Instead, the aim is to find a sweet spot, a way to balance the need to provide everyone with what they need to live a good life, a “social foundation” while limiting our impact on the environment, “the environmental ceiling.” With the help of Raworth, Amsterdam has downscaled this approach to the size of a city. The model is now used to inform city-wide strategies and developments in support of this overarching idea: providing a good quality of life for all without putting additional pressure on the planet. Other cities are following this example.
In contemporary architecture, recycling has evolved from a desirable to an unavoidable necessity. This change is mainly due to the growing climate crisis, accentuated by the constant presence of waste (for which no use has been found beyond the initial one).
This approach has stimulated the creation of innovative materials to reuse waste in various contexts. A notable example is the case of woven flooring and rugs, where Bolon took a step forward in 1949 by transforming textile waste into stylish products. Since then, they have continued to innovate in materials, fusing the traditional flooring branch with sustainable creative design.
For a long time, the construction industry has followed a linear process - extract raw materials, build structures, demolish them, and then dispose of the garbage in landfills. This approach has serious negative effects on the environment and society and is inherently unsustainable. Reconsidering traditional methods and workflows requires support from all stakeholders and a sense of urgency proclaimed by authorities. In the United States, city organizations have begun to implement new policies to keep construction waste out of landfills and support circular practices. Several cities like Seattle and Pittsburgh, have started implementing deconstruction ordinances that require older buildings to be carefully deconstructed rather than demolished. How might their key provisions influence circular practices in the country?
The principles of the circular economy have been most influential and applicable to the construction industry. Emphasizing the efficient use of resources, models around reuse and recycling of components and materials are increasingly being pioneered by global architecture practices. The concept of "design for disassembly" has emerged as an innovative approach especially in the case of building facades. Striking a balance between the demands for new infrastructure and the transition towards sustainability requires a review of traditional facade design throughout its lifecycle.
