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?
Centered on the development of architectural projects in favelas and peripheries, the work of Coletivo LEVANTE showcases a deep sensitivity to the unique characteristics and nuances of these environments. According to the group, "the recognition of what already exists and is attributed with values lived and earned by the favela residents — landscapes, constructions, identities, and relationships" is what they seek as the raw material for their projects. This approach is evident in projects such as Centro Cultural Lá da Favelinha and House in Pomar do Cafezal, winner of the 2023 Building of the Year Award by ArchDaily.
“Landscape architects have started conversations about embodied carbon. There is a realization that we can no longer ignore the grey parts,” said Stephanie Carlisle, Senior Researcher, Carbon Leadership Forum and the University of Washington, during the first in a series of webinars organized by the ASLA Biodiversity and Climate Action Committee.
The grey parts are concrete, steel, and other manufactured products in projects. And the conversations happening are laying the foundation for a shift away from using these materials. The landscape architect climate leaders driving these conversations are offering practical ways to decarbonize projects and specify low-carbon materials.
For a small child, understanding the concept of time and its passage is very difficult. As a result, children are often impatient when expecting something or confused when trying to remember something from the past. They live in the present, and learn the notion of time only little by little. But accepting the passage of time, and the reality of aging, is something that plagues us even as adults. The lucrative cosmetic and plastic surgery industries show how humanity seeks to control or deny the passage of time, an urge that has proved to be relentless.
A vital aspect of a circular economy lies in shifting our view of waste. Labeling an item "waste" implies voiding its value and ending its useful role in a traditionally linear economy. While the item might be out of sight and out of mind, its life continues in the landfill. This shift in perspective regarding waste means opening our minds to the opportunity that the abundance of junk presents. These designers and architects have managed to not only effectively reclaim discarded objects but also to make them look precious, imbuing them with new meaning and value through their careful curation.
In the global context, the first factories emerged in the latter part of the 16th century, primarily housing typographic workshops. Over time, their purposes expanded to include carpentry, tapestry, and porcelain workshops. However, the recognizable form of industrial buildings we see today only took shape in the 18th century, closely tied to the transformations brought about by the Industrial Revolution. The shift from human labor to machinery fundamentally altered the scale of these structures, turning them into expansive warehouses.
In light of the looming climate crisis and the pursuit of sustainability, the concepts of revival and reuse have emerged as crucial strategies in the quest for decarbonization in the architecture industry. These principles preach that creating new structures may be sustainable but encourage architects to minimize their ecological footprint by reactivating and recycling existing resources. This year specifically, innovative projects in line with these themes were displayed as part of the 18th International Architecture Exhibition – La Biennale di Venezia. This world-renowned event’s core purpose is to serve as a platform for architects, designers, and thinkers to collectively reimagine sustainability, decarbonization, resource conservation, and the industry's future.
Irene Roca’s “Appropriating the grid” project is born out of the contemporary ruins of our current construction processes. An exploration of the waste that is generated and the legal complexities of discarding this waste awakened a sense of urgency and creativity in the architect, resulting in a collection that molds and re-formulates construction waste into versatile interior design objects.

The role and relationship of furniture in architecture and space design are of great relevance. Designers such as Eileen Gray, Alvar Aalto, Mies Van der Rohe, and Verner Panton conceived furniture —primarily stools and chairs— that endure over time as powerful and timeless elements, with a determining impact on the interior atmosphere. Thus, the relationship between furniture and space becomes a constant dialogue in which design, aesthetics, and materials contribute their dimension.
Today, furniture should not be limited solely to fulfilling an aesthetic and functional role, but should also have a purpose in the context of contemporary design and sustainable development. It is essential to reflect on and question the processes and choice of materials in the manufacturing of these elements, in addition to the value they bring to interior spaces. In this context, HEWI has taken a step forward by creating the Re-seat family, consisting of stools and chairs made from post-industrial recycled materials (PIR), sourced in part from the processes of the company itself and a regional supplier, both based in Bad Arolsen, Germany. It also features integrated solutions with universal design in mind, making a statement in favor of innovation and eco-design.

Kengo Kuma uses materials to connect with the local context and the users of his projects. The textures and elementary forms of constructive systems, materials, and products, are exhibited and used in favor of the architectural concept, giving value to the functions that will be carried out in each building.
From showcases made with ceramic tiles to the sifted light created by expanded metal panels, passing through an ethereal polyester coating, Kuma understands the material as an essential component that can make a difference in architecture from the design stages. Next, we present 21 projects where Kengo Kuma masterfully uses construction materials.
The circular economy concept became more defined in 1990 when it appeared in the article Economics of Natural Resources and the Environment, by British economists and environmentalists David W. Pearce and R. Kerry Turner. At the time, the main purpose of the research was to demonstrate that the traditional economy did not incorporate recycling. In this way, the environment assumed a secondary role, just like a simple waste reservoir. Therefore, the circular economy would gain strength as an opposition to the linear (or traditional) economy, in which the production chain motto is “extract, produce and discard”. A model deeply rooted in our economy that has become unsustainable for several reasons, like the depletion of natural resources and the contamination of the environment resulting from production and disposal.
Almost two decades ago, in the downtown corridor of Columbus, Ohio, the century-old landmarked Lazarus Building underwent an extensive renovation to save the department store and restore it to its former glory. Sixty million dollars went into its restoration and transformation into a retail and office complex. During the construction, workers recycled nearly 5,000 pounds of steel, 2,000 pounds of concrete, and significant amounts of carpeting, ceiling tiles, and various wood- keeping 22,000 pounds of debris out of Ohio’s landfills. They also saved more than $25 million dollars by implementing this rigorous recycling process.
Environmental issues urgency and increasing temperatures on the planet are nothing new. There are many factors contributing to environmental degradation. However, two can be viewed as representative of critical points in the current world system: plastic and waste disposal, better known as garbage.
The environmental crisis cannot be attributed solely to these two examples. They are used here as examples to mobilize issues involving multiple agents, materials, and diverse methods. These issues lead to devastating consequences, increasingly irreversible.
Subscriptions are quickly becoming an integral part of everyday life. For example, streaming platforms have completely replaced the need to own video cassettes, while ride-sharing services partially cover the need to own a private car. Subscriptions have been largely understood as digital services, but a new trend suggests that the same concept could be transferred to physical objects in the near future. Instead of owning a fridge, a washing machine, or even light bulbs, one could acquire a subscription to ensure the freshness of produce, clean clothes, and a well-lit home.
The concept is known as the “subscription-based economy,” a variant of the “circular economy” notion. It postulates that instead of owning some of the objects used every day, one could subscribe to a service to gain access to the same benefits, but without the need to own, maintain or dispose of the object in question. Consumers no longer buy products; they buy access to services. Sometimes, it would mean simply leasing the object instead of purchasing it, but the model goes one step further. It inscribes a shift of responsibility and mentality. Because consumers no longer own the objects, the responsibility to reuse and recycle falls to the producers, who are now in charge of the entire life cycle of the objects they create.
RAMA Estudio has won a competition organized by the Ecuadorian Ministry of Urban Development and Housing (Miduvi) to transform public buildings into social housing. "Casa Cevallos" seeks to give a new face to the Miduvi Tungurahua building, located in front of the Cevallos Park in Ambato, Ecuador, incorporating 16 apartments for 45 inhabitants through 7 adaptable typologies.
Although the circular economy involves other principles such as the regeneration of natural systems, the reuse or recycling of materials plays an important role in contributing to the reduction of waste generation by giving a second useful life to elements that could be considered waste. Wood, metal sheets, bricks, and stones, among others, can be reused, bringing sustainability and efficiency criteria to the projects, helping to consolidate this concept that still has a long way to go.
Within the Latin American territory, many architecture professionals have proposed to apply in their design and construction processes the implementation of strategies that collaborate with the use of resources, either by reusing, recycling, or restoring different materials and elements in search of satisfying the needs and concerns of those who inhabit the spaces.
