Dust To Dust

Waste as resource / 私たちは毎日

Dust to Dust is a service that empowers businesses and consumers to redefine the value of waste.

It provides alternative materials for building, manufacturing, and living by exploring novel concrete recycling processes.


The project is enabled by research carried out at Sakai Lab, IIS University of Tokyo.

This platform connects cutting-edge material research with more sustainable commercial and citizen practices. New, zero-byproduct processes are currently being developed in the concrete engineering department of University of Tokyo, as part of efforts to develop solutions for a post-concrete society. This research responds to the increasing need to turn towards environmentally friendly resources, both on the infrastructure level and the individual level. 

Dust to Dust focuses on concrete as the most widely man-made material in existence. It is second only to water as the most consumed resource on the planet. One of its key components, cement, has shaped an immense part of our built environment, but also has an immense carbon footprint. Concrete has now become ubiquitous in urban spaces, providing building materials for most tower blocks, car parks, roads, dams, and bridges. It supports famous buildings such as the Sydney Opera House, the Burj Khalifa, and the Pantheon. However, its recycling rate does not match the production and demand rate, meaning that large amounts of wasted concrete are landfilled or discarded. 

This project is an exploration of industrial construction waste as resource, commodity, and infrastructure. It proposes a network of materials, users, and industry partners, all participating to reimagine a world with less concrete waste. The platform is composed of three pillars: Research, Service, and Community. The Research section provides an updated location for documentation of new developments concerning the use of concrete. It retraces the processes, articles, and information necessary to understand the current use of resources. The Service section allows business owners and commercial partners to integrate the new waste material into their spaces, concepts, and frameworks. The service caters to bespoke business needs, from specific types of binders to particular shapes. Finally, the community section allows every day users to connect and upload their uses of the material. Basic building blocks can be ordered and refilled. These new ideas should aim to enable low-resource lifestyles and change consumer behavior in everyday life.
