LIFE-CYCLE ANALYSIS OF PAPER BAGS AND PLASTIC BAGS House Bill No. 106 filed by Honorable Lani Mercado-Revilla stated that within three years, plastic bags would be prohibitively forbidden to manufacture, sell and used non-biodegradable plastic bag. because of the effects it caused in the environment. On the contrary, Philippine Plastic Industry Association (PPIA) said that making one paper bag can cost more than one plastic bag when it comes to the threes needed to cut, amount of water used, and the energy needed. This implies that when it comes to raw materials and energy, paper bags cost more than plastic bag. This issue is still debatable. Thus, this review paper aims to clarify things between plastic bags and paper in terms of the materials…show more content…
I. Life-Cycle Analysis of Paper Bags Paper bags are generally made from wood, specifically from wood fibers and requires. Making papers requires lots of trees needed to be cut down. Cut trees will be converted into logs then to wood pulp. Logs must be tumbled in drums to remove the barks then will be sent to grinders which will break down the wood into pulp. The pulp will then go to the process of beating inside the large tub using machine beaters. At this point, chalks, clay and chemicals such as titanium oxide can be added as well as sizing. Sizing affects how the paper react with different inks. Without sizing, paper will be absorbent. The pulp will now be turned into paper by pumping into giant automated machines. The pulp is pressed through a series of rollers and the suction device below the belt will drain off water. The paper will now be passed over a steam-heated cylinders to remove excess water.Finally, paper is polished and compacted by passing through a metal rollers and will be coated either brush or rolled on. Then the paper is cut depending on the size desired and can now be distributed to different companies who make paper bags. The finished…show more content…
They both have advantage and disadvantage. For instance, paper bags can decrease the use of plastic bags because paper bags are Eco-friendly than plastic but in paper production trees needed to be cut down just to make papers. Cutting trees and convert it to papers cause floods, soil erosion, and global warming due to lack of plants that absorbed carbon dioxide (Rubis, 2015). On the other hand, plastic bags can be use again and again but cannot be recycled because of the lower percentage of recycled materials it contains. According to an article entitled “Paper versus plastic bags”, they conducted a qualitative analysis of both paper bag and plastic bag which clarifies that paper bags required higher storage space than plastic bags in terms of compressibility. In addition, in terms of reusability, plastic bag is much higher than paper. Also, in terms of energy production demand, paper bags require lots of energy. On the contrary, in terms of biodegradability, paper is more biodegradable than plastic except if the plastic bag is made of biodegradable
