Humans have been aware of carbon since the earliest of times. The black color of smoke is caused by unburned specks of carbon.The smoke may have collected on the ceiling of their caves as soot.As with all plastics, PET allows diffusion of oxygen.
One thorny issue that needs addressing here is one of health.But the latest developmentand one making headlines in the UK at the momentis the appearance of 75 cl (standard sized) PET bottles on supermarket shelves.Two wines, a New Zealand Sauvignon Blanc and an Australian Shiraz Ros (pictured above) have been launched by UK supermarket Sainsburys in PET. PET, a plastic which has the more formal name of polyethylene teraphthalate, has been used for wine before, most commonly with small 25 cl bottles, and also with 1.5 litre bottles of plonk from the south of France.Later this year Aussie producer Wolf Blass will be launching two of its Green Label wines in PET. But this is the first time that wine in standard sized 75 cl bottles has been presented in plastic on supermarket shelves.The second reason it is newsworthy is because of the current interest in reducing carbon dioxide emissions: this project has been supported by WRAP (Waste Resources and Action Programme), a government-sponsored initiative.
