waste is resin based plastic. Plastics posses many properties such as water resistance and long life‚ that makes them perfect candidates for packaging. Unfortunately‚ the properties that make this product suitable for packaging also are the major cause of the environmental problems related to packaging. Given the wide use of plastics‚ the magnitude of the environmental problem is large and long terms. The choices for dealing with this waste are limited as incineration of plastic polymers invariably

Non-biodegradable trash that is discarded to be landfilled will only accumulate. These objects are the source of litter and pollution. The most wide-reaching effect of non-biodegradable trash is the Pacific Garbage Patch--an area of the Pacific ocean which is heavily polluted with plastics and other waste. The Pacific Garbage Patch is twice the size of the continental United

commonly used around us in many products. Most plastic factories involve bisphenol A when they are building up plastics. But‚ have you ever wondered why most factories specifically include BPA in their products? The absolute reason behind that is the fact that bisphenol A is extremely effective when it comes to making plastic products harder than usual. In addition‚ BPA is also beneficial in making plastics resistant to shattering. For instance‚ when a plastic bottle containing bisphenol A suddenly drops

proposed in this work. Plastics are inexpensive‚ lightweight and durable materials‚ which can readily be moulded into a variety of products that find use in a wide range of applications. As a consequence‚ the production of plastics has increased markedly over the last 60 years. However‚ current levels of their usage and disposal generate several environmental problems. Waste plastic disposal and excessive use of fossil fuels have caused environment concerns in the world. Both plastics and petroleum derived
