NATURAL DNA POLYMERS
Polymers are some of the core factors that enable the continuation of life, which is both the natural and the synthetic ones. Over time since the beginning of life, natural polymers were the main supports to living things. Eventually, in line with human development, synthetic polymers has become a valuable addition to the available and usable polymers.
Natural Polymers are the RNA and DNA vital in genes for life processes. As a matter of fact, the messenger RNA is the main component that makes up the bodily proteins, enzymes and peptides. Enzymes carries out most of the chemical reactions inside the living organisms, whereas the peptides bring out the characteristic features of the skin, hair and the hardy structures like the horns, nails and beaks.
Some other naturally available

Unfortunately, this feature makes the disposal of polymers difficult. As a matter of fact, most polymers like the polyethene and the polypropene are not biodegradable meaning that they are not breakable by micro-organisms. Due to this feature, these polymers last in rubbish dumps for many years. However, modern productions use chemicals that make the breaking of the polymers much easy. Polymers are incinerated or burnt to produce a lot of electricity, energy and heat which is harnessed for heating purposes in industries and at homes. On the contrary, this incineration causes production of carbon dioxide which accelerates the global warming and its effects. The carbon dioxide gases are curbed only by burning the polymers at high temperatures. Recycling. It is highly beneficial that polymers are reusable after recycling because this property reduces the demand for crude oil and disposal problems. On the other hand, this activity is highly expensive and difficult to
The recycling process of plastic begins at the recycling department wherever it may be located. The plastics are categorized according to plastic type. Plastic is then separated by color, the plastic is sterilized then crushed and chopped into plastic flakes. The plastic flakes are then melted and stirred. As a result of the stirring and melting a thick liquid is produced. This thick liquid is processed and spun into fiber strands that could be used for making fleec...
Service life The effect of fillers on polymers is that they are very beneficial because they don’t get ruined for a long time. Glass fillers are the most commonly used fillers in polymers. This is because they last longer and their service life is longer.
The words ‘Reduce, Reuse, and Recycle’ are what a person chants if someone mentions the word recycling. Nicks J defines recycling as ‘[T]he processing of waste materials in order to make them reusable” (11). Individuals who recycle are not just throwing papers in green bins, or cans in blue; in fact, they are helping the environment more than they can imagine. People who want to preserve and protect their planet take the initiative to recycle waste materials. Rather than throwing away old plastic or glass bottles, aluminum cans, and certain types of paper, one can simply recycle them, and they will go through a cleaning and the remanufacturing process to be remade into a new usable item.
The synthesis of polymers starts with ethylene, (or ethene). Ethylene is obtained as a by-product of petrol refining from crude oil or by dehydration of ethanol. Ethylene molecules compose of two methylene units (CH2) linked together by a double carbon
however, is a synthetic fiber. It is a polyamide whose molecular chains are formed by regularly
The purpose of this experiment was to create a polymer by reacting a mixture of decanedioyl dichloride and dichloromethane with a mixture of water, 1,6-hexadiamine and sodium carbonate. Specifically, we created the polymer Nylon-6,10. Nylon-6,10 polymers are used in a vast majority of things we use in everyday life such as zippers, the bristles in brushes, and even car parts. This experiment was different from the industrial method of making nylon because that takes place at a much higher temperature. A polymer is a substance that has a structure made of similar or identical units bonded together. All polymerizations fall into two categories: step-growth and chain-growth (both of which we used to form our polymer). Step growth polymerization
Today’s unprecedented technological advancement has accelerated the pace at which everyone is living. Time becomes a limited resource that every person tries to make the most use of. Therefore, convenience is the major quality highly valued in today’s world. Plastics strongly demonstrate such quality; plastics are light-weighted and disposable. Consequently, the use of plastics is prevalent, from simple objects, such as bags and bottles, to more complex components, such as computer boards. The benefits of plastics are countless; for instance, plastics are disposable and waterproof. However, many critics have raised questions regarding the threats posed by phenomenal plastics. What are the downsides of plastics? How should we cope with the plastic pollution around the globe? Susan Beraza has the answers to
Furthermore, organic compounds are considered organic because in chemistry, organic means “carbon based”. Any compound that is carbon based is considered organic. That is, an organic compound is any compound whose molecules contain carbon atoms. All living things are made of compounds containing mostly carbon. Organic compounds are important to living, and they are associated with the life processes. The properties of carbon make it the backbone of the organic molecules which form living matter. Organic compounds are important for life and they include small monomers, as well as macromolecules, also called polymers. Some organic molecules even include carbohydrates, proteins, lipids, and nucleic acids which are the essentials for life processes.
Polymer-Polyethylene is partially crystalline as well as amorphous because it has crystalline and amorphous regions. Also it has linear chains so this is the simplest structure compared to a branched or network chain. This can be of an advantage to it over other types of materials as its good toughness and elongation makes it very significant in the engineering industry as it can be moulded or extruded into shape...
There are six classifications of plastics, each assigned a number. Numbers 1 and 2 are commonly recycled, 4 is recycled less, and the others are generally not recycled. The first is polyethylene terephthalate (PET).[2] PET is commonly used in making liquid containers such as plastic soda and water bottles and has many other applications.[1] Recycled PET also has many applications, including textiles, sheets for tapes, and the bottle market.[2] The second type of plastic is high-density polyethylene (HDPE). HDPE is used in milk, detergent, and oil bottles and plastic bags. It is crushed into flakes and washed, then dried and shaped into pellets. Some uses for recycled HDPE are trash cans, flower pots, lumber, and other non-food applications.[2] The third type of plastic is vinyl or poly vinyl chloride (PVC). Low-density polyethylene (LDPE) is the fourth type of plastic, and is used in many plastic bags and shrink wraps. It has the same chemical makeup as HDPE but is less dense and more flexible. Recycled LDPE is used for plastic trash bangs and grocery sacks and plastic lumber, as well as several other applications.[2] The fifth type of plastic is polypropylene (PP), which is used in food wrap, some carpets, and bottle tops. P...
The future for these products is also quite often over looked. The components are not made to be detachable, so the different materials cannot be recycled correctly or recycled at all, which leads to landfills and pollution. Every material, from wood to steel to carbon fibre has an environmental story behind it and these can all be reused, however there is quite often not enough thought into this design aspect. These components are not labelled correctly for recycling and the result is a scarred landscape. However recycling these days has now turned into a way of life for us. Bins are now everywhere marked with the unmistakeable ‘three-green-arrow’ (another remarkable graphic design – now playing a huge role in the way we live), which lets members of the public kn...
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
from different resins. In order to recycle plastics, the different types must be kept separate.
Recycling is of great importance, and its importance is economic and environmental. It preserves natural resources, reduces depletion, reduces the amount of waste, reduces its growth, conserves the environment, cleanses it of some harmful waste, reduces unemployment and creates opportunities. New work.
There are also several long term benefits of recycling. For example, “collecting and processing secondary materials, manufacturing recy...
