Narrative: CD backups

An archive of work on CD and DVD backups was made in case of an EMP attack (or something similar) or if backup hard drives stopped functioning for some other reason. Materials that make up this collection are many, from paper to plastic, metal to ink. This is a disorganized, uncomprehensive array of information.

Copper sourced from Chile, Peru, or Ecuador and produced in a factory in the United States; aluminum from Russia or China; polycarbonate plastic from California, South Africa, Somalia, South Korea, or Germany; boxite from Australia, and parts assembled in a factory in the United States.

The larger supply chain includes: Petroleum refineries; Power generation and supply; Plastics material and resin manufacturing; Coal mining; Alumina refining and primary aluminum production; Oil and Gas extraction; Motor vehicle parts and manufacturing; Truck transportation; Iron and steel mills.

The Dow Chemical Co. began manufacturing zip lock bags in 1968, but today the Ziploc brand is marketed by S.C. Johnson & Co.  Polyethylene plastic is melted down to a point in which it is pliable. It is then poured into a very thin mold that is in the shape and size of the bag. The closures on the bags are formed in separate molds out of stronger, thicker plastic. A plastic slider zipper is used to push the lips of the bag closed and to fasten them shut. There is male and a female track. The male track locks into the female track fastening closed and requiring quite a tug to be opened again. The closure is durable enough that you can hold the bag upside down and the contents will not spill out onto the floor.  Low-Density Polyethylene (LDPE). Plastic Recycling Number/Resin ID Code #4. Polyethylene plastic resin is the most commercially used polymer that is available in a large range of flexibilities and densities.  Ziplock plants are located in Bay City, Michigan and in Fresno, California.

Petroleum refineries; Power generation and supply; Plastics material and resin manufacturing; Coal mining; Alumina refining and primary aluminum production; Other basic organic chemical manufacturing; Oil and Gas extraction; Motor vehicle parts and manufacturing; Truck transportation; Oil and gas extraction; Iron and steel mills. Land use includes: Logging; Forest nurseries, forest products, and timber tracts; Cattle ranching and farming.
