Background of the study
Due to the overwhelming demand of plastic bag production and its effects on our environment, our landfills are crammed with these non-biodegradable materials. Substances used in the manufacturing brought forth various harmful chemicals which worsen over time. As the destructive compounds such as Chlorofluorocarbons were introduced, the complete deprivation of the Ozone Layer starts. However, scientists and nature preservers alike managed to overthrow this hazard, but not entirely. To compensate for the damages, eco products were released. These are the most commonly made of recycled and/or natural organic materials. They utilize nature’s abundant supplies to create a replica or substitute for our plastics. One example would be the “Biodegradable plastic bags” made from the starch of the Cassava plant (Manihot esculent). The new plastic has been able to capture the interests of buyers, enabling it to advocate the benefits and obvious effects one can receive from using an eco-friendly product. To further elaborate the example, scientist and researches aim to discover another substitute for this product and perhaps develop a completely new one along the way. Current findings are apparently still limited to the actual Cassava ingredient. Today’s plastics are designed with little consideration for their ultimate disposability or recyclability. This has resulted in mounting worldwide concerns over the environmental consequences of such materials when they enter the waste stream after their intended uses, Of particular concern are polymers used in single use, disposable plastic applications. Plastics are strong, light-weight, inexpensive, easily process able and energy efficient. They have excellent barrier properties. They are disposable, and very durable. However, it is these very attributes of strength and indestructibility that cause problems when these materials enter the waste stream. They are not readily broken down by...
