Plastics are materials composed of artificial inorganic chemicals are quite dangerous enough for the environment. Instead of plastic waste is very difficult to be degraded naturally. To describe the plastic waste itself requires approximately 80 years to be degraded completely. Therefore the use of plastic materials can be said to be unfriendly to the environment or conservative when used without the use of certain restrictions. While in everyday life, we uses plastic materials we can find in almost all activities of our lives. And if we are aware, we are able to do more for this is by using the back (reuse) plastic bags stored at home. Thus indirectly we have reduced plastic waste that can be wasted after use (reduce). Or even better if we can recycle the plastic into something more useful (recycle).
Plastic is a material different physical properties, mechanical, and chemical. Broadly speaking, the plastic can be classified into two major categories, namely plastics are thermoplastic and which are thermoset.Thermoplastic can be reshaped easily and processed into another form, whereas type when it has hardened thermoset can not be softened again. The most common plastics used in everyday life are in the form of thermoplastic.
Utilization of waste plastics with recycling is generally done by the industry. In general there are four requirements for a plastic waste can be processed by an industry, among others, certain wastes must be in the form as needed (seeds, pellets, powders, shards), wastes must be homogeneous, not contaminated, and sought not oxidized. To overcome this problem, before use of plastic waste is processed through simple steps, namely splitting, cutting, washing, and removal of substances such as iron and so on.
In addition, the efforts of plastic waste into products that are functional and have a high selling power at present has a bright prospect, let alone the current issue of global warming and green areas echoed many of the world community and is able to arouse public awareness to appreciate the leftovers / wastes such as waste plastic.
Besides the impact of the adoption of the manual system in the printing of plastic products in addition to reducing the exploitation of the use of pure raw materials (virgin material), plastic waste processing chain also will involve many actors recycling or in other words can absorb a lot of manpower which means it can reduce the burden of unemployment .
Here are a plastic recycling process using a special machine plastic recycler:
1. Sort, separate raw materials and dispose of the material / foreign substances that are not expected to go into the recycling process.
2. Cutting and chopping in the form of original plastic (bags or plastic sheets.
3. Laundering in order not to interfere with the milling process, in a way Prewashing using liquid media as a means for separating foreign materials, especially in order not to participate in the next process is Laundering Phase 2 using water friction machine where the material was washed again by a screw that rotates upward at high speed so as the result of friction can release foreign material left on the material.
4. Mechanical drying is by squeezing the material in a circular motion so that water can come out and by evaporation of water at a certain temperature so that the material completely free of the inherent temperature.
5. Heating the material that has been cleared of impurities are melted by heating the material at a temperature of 200 degrees C where the temperature of the heat generated by the heater and then streamed to melt into the screening process.
so from now we are using plastic to a minimum to preserve our natural and keep our earth today and for the future.
