Plastic scare (2)

After some bits of researching...my conclusion (to cut all my crapz, no one wants to know;P)

plastic code 1,2,4,5 (these are ok for repeated usage) class 1 & 2 are the better ones compared to class 4 & 5

plastic code 3,6,7...if you have been re-using any of these, you'd better throw them into the bin now...

some brief info about the recycling codes

Class 1: Polyethylene Terephthalate (PET, PETE) e.g. Plastic soft drink, water, sports drink, beer, ketchup and salad dressing bottles. Peanut butter, pickle, jelly and jam jars. Ovenable film and ovenable prepared food trays.

Class 2: High Density Polyethylene (HDPE) e.g. Milk, water, juice bottles; yogurt and margarine tubs; cereal box liners; grocery, trash and retail bags

Class 3: Vinyl (Polyvinyl Chloride or PVC) e.g. Clear food packaging

Class 4: Low Density Polyethylene (LDPE) e.g. squeezable bottles, e.g. honey, mustard.

Class 5: Polypropylene (PP) e.g. Plastic containers, water tumblers/bottles, ketchup bottles, yogurt containers and margarine tubs, medicine bottles.

Class 6: Polystyrene (PS) e.g. food service applications, cups, plates, cutlery

Class 7: Other - e.g. water bottles, juice and ketchup bottles.

The major risk involved is generally consumption of carcinogenic plastic residues (which could accumulate in one's body over time). Plastic residues could leach from plastic ware due to repeated usage, regardless if you microwave it or not...for example merely shaking mineral bottle containing water could cause the plastic residue to be leached from the plastic bottle into your drinking water, also the fact that we do not know how well the bottles are handles before we buy them...for example if they are exposed to sunlight, chemical reactions could take place and plastic residues leach into the drinking water

my current ISO consultant also mentioned that mineral plastic bottles has been banned in Europe...

if anyone wants to be totally safe from risks of consuming plastic residues, the better option is to replace plastic with stainless steel-aluminum ware or glassware - well, the latter is not so recommended for water bottle i guess, especially for a clumsy person like me;PP)
