IMPORTANCE OF PLASTIC:- Plastics are a subset of materials known as Polymers. These are composed of large molecules formed by joining many smaller molecules together (monomers). Other kinds of polymers are fibres‚ elastomers‚ surface coating and biopolymers‚ such as cellulose‚ proteins and nucleic acids. Plastics owe their name to their ability to be shaped to form articles of practical value by various conversion and forming processes. These are some peculiar properties of plastics materials‚ which

A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural.[1] A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable.

A means of addressing this problem will be the aim of this project study. 1.2 Statement of the Problem The main problem of this project proposal was on how to save money and time and to reduce the anxiety of the students in inquiring about the status of their academic performance at the end of the semester. This project proposal aimed to answer the following questions: 1. Does this alert system would help the students determine their grade status periodically? 2. What would be advantages

recycling of plastics bringing any long-term benefits to the environment? Plastics are one of the most popular building materials of modern human culture‚ but its widespread has brought many problems and caused environmental issues of extraordinary scale. Throughout the years‚ discarded plastics are accumulating as debris in landfills and in natural habitats worldwide. To control this issue‚ governments of many countries have established industrial processes for transforming discarded plastic into useful

If people are offended by a book‚ depriving the entire state of their ability to read that certain book is not the solution. There are various other ways to ensure that parents who do not want their children to read particular books without abolishing them from the entire school.

Plastics are synthetic substances produced by chemical reactions. Almost all plastics are made from petroleum‚ except a few experimental resins derived from corn and other organic substances. "Plastics" derived their name from their properties to be molded‚ cast‚ extruded or processed into a variety of forms‚ including solid objects‚ films and filaments. These properties arise from their molecular structure. Plastics are polymers‚ very long chain molecules that consist of subunits (monomers) linked
