starche(sugar) or protein based(amino acid) base
PLA
plant-based (from ntural sugar resources)
used instead of PETE 1
biodegradable
cannot mix with PETE
114deg melting point (don't leave in car)
fasalex
Nylon 11
plant-based from castor bean oil
non compostable
energy inefficient in manufacture
PE/PP/HDPE
best petroleum-based
widely recycled #2, #4 and #5
PET/PETE/polyester
too much additives--UV stabilizers and flame retardants
widely recycled #1
ABS/polycarbonate(PC)/polyurethane/polystyrene(PS)
all consumer electronics
carcinogenic
mutagenic
PC uses solvents in manufacturing process
PC are recyclable but hard #7
ABS and PC difficult recycle #6 or 'other'
pro ABS: easy to find and use recycled ABS grind
PVC
very toxic--avoid
carcinogenic
uses toxic plasticizers
difficult recycling #3
aluminium
won't rust
almost all extrusions on consumer goods
2-3% of US electricity is al manufacturing
recycled al only uses 5% of inital energy consumption
steel
uses less than 1/8 (almost 1/9) as much energy to produce as aluminum
stainless steel as bad as vigin aluminium
titanium
machines at between 10-20 times slower than
According to the US Geological Survey's 2006 report, "Recycled Cell Phones? A Treasure Trove of Valuable Metals", there's 40 cents of gold, thirteen cents of palladium, six cents of silver, and a few cents of copper and platinum (not to mention the penny or two of plastic case, which makes up 58% of a cell phone by weight).

DIY conductive glass >>
intumescent glass
double-glazed with an inner layer of transparent sodium silicate that, when exposed to high temperature, turns opaque and forms an insulating layer that can provide up to a 2-hour fire resistance rating.

wood foam
ceramic foam
water vapour can pass through, but not liquid
cannot be reycled as paper-DuPont has recycling program Garment Recovery Systems
highly flammable-shrinks away
dyneema/spectra
thermoplastic: deformable, melts to a liquid when heated and freezes to a brittle, glassy state when cooled sufficiently
15 times stronger than steel
no fibre filaments released when cut
high energy absorption (bullet-proof)
resistant to moisture and rotting
excellent weight-to-strength ratio (high strength, low weight)
gloves, vests,rope, fish net, yachting sails...
moisture wicking (hands won't sweat)
spun to shape or sewn with dyneema thread
quantum tunneling composites
intrinsically electrically insulating, shows a dramatic increase in conductivity over many orders of magnitude when subjected to only gentle mechanical deformations such as compression, tension, bending etc.
switches and sensors woven into textile
currently used by NASA for controls embedded onto gloves
resistance range from as high as (10)12ohm to as low as 0.5ohm
