Document Summary
Enbus 204: materials and materials flow analysis (mfa) Plastics pros (lighter more efficient) cons ( toxicity, unknown to ecosystems, lack of technical cycles to accommodate them) Why the shift in materials there was a shift because technology improved this lead to a change in ages. Primary materials = principally from virgin resources aluminum from bauxite steal bfo (basic oxygen furnace) and glass use both virgin and scrap. Secondary materials = recycled materials aluminum from scrap (uses much less energy) Steel eaf (electrical arc furnace) uses 100% scrap. Redesign products and process to reduce mater and energy use. Remanufacture disassemble, refurbish, reassemble (design for. Recycle- use waste materials to produce new (primary/virgin and secondary/recycled materials) Reservoir the bucket is a reservoir the stock is what in it. Flow what is leaking from the bucket. W is waste what you do at the end of its life time.
