RRDC –the Recovery and Reuse Decontamination Center –is a facility that cleans discarded yet usable medical materials so they can be reused rather than wasted. Plastic is the chief material accounting for medical waste: it is predominantly used to quickly package, seal and protect tools from the external environment then readily discarded after first external contact. In critique of this “single use” phenomenon, RRDC has evaluated the relationship between material, cleanliness, and temporality. RRDC’s facilities are composed of smooth and seamless surfaces that are fabricated from cast concrete sealed with epoxy coatings.The corner less, monolithic nature of the concrete form establishes both a pristine yet enduring structure. RRDC does appreciate and embrace the flexibility of plastic materials. The plastic envelope expands vertically to enclose a temporary, secondary floor for can be used for medical device decontamination during a health crisis and periods of high medical device demand. The expansion floor of the building utilizes latex to create a resilient cover for surfaces of irregular geometries.
