Bioplastics
Bioplastics are a different variation of plastic, that are more environmentally friendly than regular plastics. Instead of using crude oil to create plastic, bioplastics use corn and other organic materials to create plastics. Also, Bioplastics are combustable, which means they can decompose instead of slowly rotting in a landfill. One example of a Bioplastic being used today is in Sun Chip bags. Theses are biodegradable bags can decompose and therefore not cause any pollution and is made completely of bioplastic.These However there are many problems with the manufacturing of bioplastics. In order to grow the organic plants needed for green plastics farms use a lot pesticides and crude oil to power the tractors and other equipment. Also, the factories use a lot of electricity which is made using crude oil. Another concern is taking up land to farm products for plastics could effect the world food supply, possibly causing a worldwide food shortage and could harm the rainforests because of cutting down trees and destroying land. You cannot combine different types of plastics because their melting points are different and the plastics are a lot less strong and break easily. Polyactic acid is a type of bioplastic that is made by combining Lactic acid oligemers which are turned into Lactide and become Polyactic acid. To create normal plastic you combine diffrent Monomers for RO2H2 and create Polymers that release H2O (water) when they combine. When you create Bioplastic CO2 (carbon dioxide) is released. This video connects to Blue Gold because it shows the importance of keeping our environment clean and using new technology to stop polluting the water by stopping our dependence on mining for crude oil. Overall bioplastics show promise for helping create a more environmentaly friendly industry.

You did a great job on your reflection! I agree with you as we should not combine different plastics because it basically makes products less durable. We should also think about the effects that might be caused due to the pesticides and gases released into the air.
ReplyDeleteGreat job!
