Plastics

From the mid-1980s onwards, plastic bags became common for carrying daily groceries from the store to vehicles and homes throughout the developed world. As plastic bags increasingly replaced paper bags, and as other plastic materials and products replaced glass, metal, stone, timber and other materials, a packaging materials war erupted, with plastic shopping bags at the center of highly publicized disputes. Although few peer-reviewed studies or government surveys have provided estimates for global plastic bag use, environmental activists estimate that between 500 billion and 1 trillion plastic bags are used each year worldwide. Plastic has replaced the traditional material (paper/cloth etc) as packing and carry bags because of cost and convenience which is possibly a wrong choice of material for…

Plastic Bags

Hanging from the branches, flying in the air, stuck in corners racing along with the vehicles on the road are – as we all can see – plastic bag. This wonder material of the 20th century has invaded every aspect of our lives; it is all over the place messing up the streets and parks, clogging up the drains and gutters. These plastic bags or shoppers as they are commonly called are available in all sizes, shapes and colours, and because of their lightweight, flexibility and low cost they are used and cast off freely. Today people from all walks of life use plastic bags mainly because of their easy availability and convenience. Their use is so widespread that it…

Plastic Q-Tips

Since the swabs of Q-Tips are made up of cotton, one of the environmental impacts of manufacturing them in huge quantities throughout the year is that it makes use of tens if not hundreds of millions of paper or plastic sticks for the rod holding the cotton swab. Apparently, the paper sticks are generally manufactured from trees, thereby posing the threat to the environment in terms of trees being cut down solely for the purpose of turning them into small paper rods. On the other hand, plastic Q-Tips rods disposed by the millions can eventually form into a massive heap of plastic garbage when combined altogether. Since these are made up of non-biodegradable material, there is an urgent need to…

Plastic Recycling

Due to increased the high residence time in the environment, old and used plastics require recycling to not only ensure clean and healthy environment, but also maximize the resource utility. Sorting/ separation is one of the most important stage in the recycling process as it differentiates the plastics from other materials and categorize it into various forms. Depending on the origin of the plastic materials, the sorting process is made easier especially if there was initial separation at the source where plastics are put in different containers from the others types of wastes. Physical sorting method According to Plunket (2005), this separation method involves use of the visible and physical characteristics of the plastics to remove them from other waste…

Dangers of Plastic Bottles

Plastic bottles are hugely popular these days for their convenience and perceived purity, as portrayed by effective marketing strategies. But according to the Natural Resources Defense Council, consumers should not assume that bottled water is safe.  Reusing plastic drink bottles is not recommended, as it increases the likelihood of impurities due to the introduction of bacteria and the potential leaching of plastic compounds into the water. Common Types of Plastic Drinking BottlesPolyethylene terephthalate or (PET plastics) are most commonly used for disposable plastic water bottles. High-density polyethylene, or HDPE (No. 2); low-density polyethylene, or LDPE (No. 4); and polypropylene (No. 5) are also used for drinking containers, though less frequently. PVC (No. 3) and styrene (No. 6) are sometimes used…

Related Literature and Review of Related Studies for Fertilizer

Commonly known as ‘Styrofoam’ that is one of the most widely used type of plastics. It is a strong plastic created from erethylene and benzine that can be injected, extruded, or blow molded; making it a very useful and versatile manufacturing material. It is also a rigid, transparent thermoplastic, which is present in solid or glassy state at normal temperature. But, when heated above its glass transition temperature, it turns into a form that flows and can be easily used for molding and extrusion. It becomes solid again when it cools off. This property of polystyrene is used for casting it into molds with fine detail. Pure polystyrene polymer is colorless and hard with limited flexibility. Polystyrene is hard and…

Harmful Effects of Plastic

Composition and Types of Plastic A plastic is made up principally of a binder together with plasticizers, fillers, pigments, and other additives. The binder gives a plastic its main characteristics and usually its name. Thus, polyvinyl chloride is both the name of a binder and the name of a plastic into which it is made. Binders may be natural materials, e.g., cellulose derivatives, casein, or milk protein, but are more commonly synthetic resins. In either case, the binder materials consist of very long chainlike molecules called polymers. Cellulose derivatives are made from cellulose, a naturally occurring polymer; casein is also a naturally occurring polymer. Synthetic resins are polymerized, or built up, from small simple molecules called monomers. Plasticizers are added…

Plastic Pollution

Many individuals underestimate the amount of plastic we use each day. According to the article “Plastic Bags Wars”, “the world consumes 1 million plastic shopping bags every minute”. Plastic bags, along with many other types of plastics, have become a leading source of pollution worldwide (Doucette). Captain Charles Moore, founder of the Algalita foundation states that we use two million plastic bottles in the United States every five minutes. Discovered by Charles Moore in 1997, the “Great Pacific Garbage Patch” is a prime example of the amount of plastic pollution that enters the ocean from land. The Great Pacific Garbage Patch has been described as a filthy plastic collage of discarded cups, straws, lids, bags, and food container’s. These giant…

Husky – Injection Molding Systems

Husky Injection Molding Systems is a global supplier of injection molding systems for the plastic industry serving customers in over 70 countries from 33 service and sales offices in 25 countries. (1) Husky announced a shift in its business strategy, in which they plan to quit production of closure molds and close their industrial mold shop located in Auburn, Massachusetts. (2) They intend to focus on their core businesses of making machines and molds for the production of PET (polyethylene terephthalate) preforms. (3) They also plan to add bottle development services to further take advantage of the growing PET market. (4) A Short History of Husky Leading to the Shift in Strategy. Robert Schad who emigrated from southwestern Germany in…

Paralyzing plastic

Plastic bags are everywhere. They are in grocery stores, in people’s home, in trash cans, in landfills, in sewers, in rivers, in oceans, and in the bodies of the animal. Plastic bags are hazardous; they are contributing to plastic pollution which is posing as a huge threat to the modern ecosystem. On the surface, it would seem that use of plastic is cheap and convenient, but there is a deadly price that is paid for that convenience. The real price of using plastic is a deadly one and causes detrimental damage to the environment. The use of plastic bags has already been banned in many countries such as Italy, China, and some parts of The Philippines. Many cities in the…
