Plastic waste is a problem for the environment. Not only a problem for developing countries, but also for developed countries around the world. This problem must be addressed immediately so as not to get bigger.
Plastic is a synthetic polymer material that never loose in everyday life. Plastics have become an important part and become the primary needs of everyone. Ranging from home appliances, school supplies, computer equipment, phones, cables, children’s toys. Also food wrappers to artificial heart valves, all do not escape the interference of these synthetic polymers. Plastics have many meritorious and provide convenience in meeting their daily needs. But is it true that there is no problem caused?
The Polymer’s Hazard
Before discussing more about the problems caused by the use of plastics and the prevention, it is better if the authors discuss briefly about the polymer. Polymers are classified into two kinds, namely natural polymers (such as starch, cellulose, and silk) and synthetic polymers (such as vinyl polymers). Plastics known everyday are often interchangeable with synthetic polymers. This is because easily formed plastic properties (Latin, plasticus = easily formed) are associated with synthetic polymers that can be melted and converted into various shapes. In fact, plastic has a more narrow meaning.
Plastics include thermoplastic polymer parts, the polymers that will soften when heated and can be formed according to the pattern we want. Once cool the polymer will preserve its new shape. This process can be repeated and can be transformed into another form. Another class of synthetic polymers is a thermoset polymer (a material that can be melted at some stage in its manufacture but becomes hard forever, not softened and can not be reprinted). Examples of this polymer is a widely used for radio equipment, toilets, and others.
The discovery and development of synthetic polymers is based on the presence of several limitations found in the utilization of natural polymers. Synthetic polymers whose development is very rapid is plastic. The ease and privilege of plastics has replaced the use of materials such as metal and wood in helping human life. Examples of plastics widely used in daily life are polyethylene (packing material, plastic bag, toy, bottle), teflon (metal substitute, cooking utensil), polyvinylchloride (for pipe, household appliance, paint, phonograph ), polystyrene (electrical insulators, food wrappers, styrofoam, toys), and others.The increasing number of the world population, it also increases the use of natural resources and energy on a large scale. This causes the amount of waste to be greatly increased.
Among the waste, plastic waste is the most difficult waste handling, because plastic waste can not decompose in the environment. As a result, plastic waste has become a large-scale environmental problem and should be sought after its completion.In developed countries, various methods of solving waste problems have been tested, from the smallest to the largest scale. The results of this study have provided an overview in choosing one of the most appropriate models to be applied to adapt local environmental and resource conditions.
In the handling of organic waste with household waste composting technology, the process is very dependent on the “miracle” of bacteria, both aerobic bacteria and anaerobic bacteria that help the process of fermentation or decomposition. Scientifically, the results of these experiments are very significant to help reduce the accumulation and contamination of toxic waste content of household waste. Waste processing technology using sanitary Landfill method, Mini Composter, Vermicomposting, Incinerator, Open Windrow, Aerial Tub, Bio Filter and many more is an alternative way to solve garbage problem. Each technology has very different characteristics in its application or operation. If you are not careful selecting the technology used, it will be fatal for users, both in terms of economic, health, time and emotion. This can happen because each technology has many specifications, such as the size and type of raw materials, treatments, and special care.
