Reference: Circular Manufacturing of Bio-Composites (SUTD)
Researchers from the Singapore University of Technology and Design (SUTD) have developed a process that allows for the production and degradation of almost any object within a circular economy using additive manufacturing and urban waste, the largest by-product of civilization.
Inspired by the cyclical mode of production and degradation of biological materials by organisms using limited energy and material resources found within localized conditions, the researchers, together with its collaborators, focused on translating those principles in urban ecosystems. This was to reduce its reliance in intercontinental transport, energy demanding manufacturing processes, use of harmful chemicals substances, and dependence on man-made synthetic materials which require complex reclamation procedures past their end-of-life.

SUTD researchers from the same team previously developed a fungus-like adhesive material, also known as FLAM, by effectively transforming chitin and cellulose, into materials for sustainable manufacturing. Derived from the shells of crustaceans and insects, as well as wood and paper, respectively, chitin and cellulose are the two most abundant organic polymers on earth. Touted as a 'green' alternative to plastic, FLAM is not only biodegradable, flexible, and durable; it can be mass-produced on a large scale using 3-D printing technology.
Cellulose can be easily obtainable from urban waste such as tissue paper, textiles, and plant matter. However, despite the ubiquitous nature of chitin, this polymer is mostly harvested as an industrial and agricultural product. For instance, chitin is mostly available as a seasonal by-product of the fishing industry and is limited to rural coastal areas. This means that chitin would be needed to be transported over different ecosystems when there is a demand, contributing to freight transportation, which is known to be a key contributor to carbon dioxide emissions.
Reference: Pace Layer Model (Stewart Brand)
The interplay between each layer in the model, the “slip zones” is where, as Stewart says, “all the action is.” The outer layers move more rapidly than the inner ones but each ring is not independent. There is tension of one upon the other so that something like fashion, which wiggles back and forth, revisiting and revising itself over time influences the other. As one ring moves, there is a viscosity between each layer and there is a tension that pulls and pushes neighboring layers so that changes in fashion lead to changes in commerce which then influences the infrastructure necessary to support that commerce and so on.
When the tension becomes too great, we get “slippage” that must be absorbed to prevent the system from breaking apart. Like tectonic plates along a fault line, if one layer gets too out of sync with another, the shock from rapid movement of a layer causes ripple effects felt throughout the system. Healthy systems can incrementally absorb movements at their own speed. Those that cannot, because of inflexibility, crack and break as a result of the stress. If a government cannot adjust, it will ultimately be overthrown. If commercial pressures in pursuit of ever greater profits outstrip the ethics of a culture, that too may break apart a system.
