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…

The Use of Biodegradable Plastics

The “normal” plastic products that we use everyday (such as plastic bags, plastic food packaging, plastic eating utensils etc.) are manufactured from non-renewable sources (coal, oil and natural gas). These plastics are non-degradable and take more than hundreds of years to break down in landfills, while 29 billion tonnes of this non-degradable plastic waste are dumped into those landfills every year worldwide! [Recyclaholics: The Facts] That plastic waste doesn’t just take up loads of space; it also releases methane, a…

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…

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…

Manufacturing Case Study

Introduction Before a manufacturing process can be selected to manufacture a component many things need to be considered. The design of the product, the functionality, the service conditions and the properties of the material all play a big part when considering the manufacturing process. This study looks at Polypropylene Chairs used mainly for education purposes. It provides information that explains the purpose of a chair; the requirements of this particular product and the manufacturing process that produces the final component….

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.
