Parkesine, the first member of the Celluloid class of compounds and considered the first man-made plastic, is patented by Alexander Parkes. [4] 1869: John Wesley Hyatt discovers a method to simplify the production of celluloid, making industrial production possible. 1872: PVC is accidentally synthesized in 1872 by German chemist Eugen Baumann ...
Szigeti and Davis (Performance Based Building: Conceptual Framework, 2005) explain that "the dialog between client and supplier can be described as two halves of a "hamburger bun", with the statement of the requirement in functional or performance language (FC - functional concept) matched to a solution (SC - solution concept) in more technical ...
The plastics industry manufactures polymer materials—commonly called plastics—and offers services in plastics important to a range of industries, including packaging, building and construction, electronics, aerospace, manufacturing and transportation.
A bun is a type of bread roll, typically filled with savory fillings (for example hamburger). A bun may also refer to a sweet cake in certain parts of the world. [ 1 ] Though they come in many shapes and sizes, buns are most commonly round, and are generally hand-sized or smaller.
Life cycle assessment (LCA) is sometimes referred to synonymously as life cycle analysis in the scholarly and agency report literatures. [7] [1] [8] Also, due to the general nature of an LCA study of examining the life cycle impacts from raw material extraction (cradle) through disposal (grave), it is sometimes referred to as "cradle-to-grave analysis".
The C2C concept ignores the use phase of a product. According to variants of life-cycle assessment (see: Life-cycle assessment § Variants) the entire life cycle of a product or service has to be evaluated, not only the material itself. For many goods e.g. in transport, the use phase has the most influence on the environmental footprint.
For example, recycling one ton of plastic in a closed-loop system saves about 7.4 cubic yards of landfill space. Since the grocery industry demonstrated [ when? ] that consumers use at least 690,000 tons of plastic in a year, universal implementation of ideal closed-loop recycling systems could save at least 5.1 million cubic yards of landfill ...
Plastic recycling is the processing of plastic waste into other products. [1] [2] [3] Recycling can reduce dependence on landfills, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [4] [5] [6] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper.
