بيت /Estimating Emissions From Shredding Plastic
PET is the type of plastic most commonly used for beverage bottles. Other sources pin the production ratio of carbon emissions to plastic production closer to 5:1. Worldwide, we consume approximately 100 million tons of plastic each year. From the EPA's more conservative estimate to the more liberal one, that's anywhere from 100 million tons of ...

· A number of people have asked about the impliions of using plastic bags on the personal carbon footprint as well as on the environment in general. There are some comparisons between paper bags and plastic bags available which clearly show that it all depends on how many times these plastic or paper bags are being used. Littering is probably the severest problem related to plastic .
