Dealing with polymer waste Polymers can be made into a huge variety of items rather easily; this is why it is so popular. Nowadays it is used everywhere from everyday items such as cups‚ milk bottles and plastic bags‚ to medical and laboratory equipment. All applications use different types of polymers such as polyethene‚ polyvinyl chloride and polypropene. Polymers‚ also‚ can be used as a fuel source by burning under controlled conditions to release heat energy and therefore electricity. Despite

A polymer is a substance formed by many molecules that are all strung together to form a long chain‚ and has been around since the beginning of time (Polymer). Examples of different polymers being used in everyday life are things like rubber and starch‚ which are both frequently used in the world (Brewer). Polymers also make up what are known as “polymer creatures‚” which are the things that are used in experiments about polymers. The polymer creatures‚ made out of two different polymers‚ are both

must grow and develop through their three trimesters. Also before a plant is full-grown‚ it must first mature and survive as a seedling. Because although living creatures may be the most evident of Mother Nature’s creations‚ there may be more to it. Life is only possible in a suitable environment. On earth‚ that environment is created by our weather dynamics. Weather dynamics is the study of how the motion of water and air cause weather patterns. Our Global weather systems are reflections of our atmosphere

COMMON SYNTHETIC PLASTICS INRODUCTION Plastic molecules are made of long chains of repeating units called monomers. The atoms that make up a plastic’s monomers and the arrangement of the monomers within the molecule both determine many of the plastic’s properties. Plastics are one of the classification of polymers .If a polymer is shaped into hard and tough utility articles

Textiles are made up from natural or man-made fibres or a combination of both. “Fibres are thin‚ hair-like structures” (Blair‚ n.d: online) that are categorized into two types: long filament fibres and short staple fibres. Natural fibres are usually staple‚ whilst man-made fibres are filament‚ with the exception of silk that comes from a natural source. These raw fibres are spun to produce a long‚ continuous thread referred to as yarn‚ which is then used in a series of methods that include‚ stitching

Synthetic Fibers Industry Synthetic fibers are the result of extensive research by scientists to improve on naturally occurring animal and plant fibers. In general‚ syntheticfibers are created by forcing‚ usually through extrusion‚ fiber forming materials through holes (called spinnerets) into the air‚ forming a thread. Before synthetic fibers were developed‚ artificially manufactured fibers were made from cellulose‚ which comes from plants. These fibers are called cellulose fibers. Raw materials:

An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons‚ giving it a net positive or negative electrical charge. The name was given by physicist Michael Faraday for the substances that allow a current to pass ("go") between electrodes in a solution‚ when an electric field is applied. It is from Greek ιον‚ meaning "going." The word ion also is responsible for electrical current being symbolized by the letter i in chemistry and physics. An anion
