Sorting recycling process is a new technology for me to learn and it helps recycling a lot about separate waste. I realize it is necessary to do refuse sorting consciously by out self, because use machine to separate waste is the environmental behavior although it is a kind of energy waste.
The video describes deeper about sorting recycling on glass. We usually use glass bout normally do not think about different colour glass can be separate recycling. Same as above, I think even the computer system can do accurate sorting work although need people improve the level of recycling consciousness. Like the knowledge from last lecture, companies can come to use same glass bottles and different label can be replaced rather than waste more energy to recycle.
Paper recycling had been used for long time and this process protects huge forest on earth. People already realize recycling paper is the reduction of the environmental impact of waste during manufacturing, converting/printing, collecting, sorting and recycling processes to ensure the optimal and environmentally sound recycling of used paper and board products.
Steel cans are the main items for recycling tinplate and almost steel cans can be recycled, manufacture and reuse again. Although, I think recycling tinplate technique can be improve because it need lots of energy like sorting, ovens, and manufacture. So that a tried tested recycling process can improved on, however, and the recycling of tinplate packaging is continuously being developed and improved.
Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. Also, aluminium seems like a prefect recycling material but the process of recycling aluminium need to spend lots of energy rather than the effects of recycling. Also, aluminium is not cheaper as we think so that the vast amount of aluminium used means that even small percentage losses are large expenses, so the flow of materiel is well accounted for financial reasons.
Tetra Pak is finding its way all over the grocery store. Milk, wine, soup, and many other items are using it and the Tetra Pak packages can be fully recycled. Also, from the video I realize that Tetra Pak carton boards are substituted for plywood, and used for items, like picture frames, desk organizers and small furniture.
Plastic recycling is the process of recovering scrap or waste plastics and reprocessing the material into useful products, sometimes completely different in form from their original state. When compared to other materials like glass and metal materials, plastic polymers require greater processing to be recycled. Also, before we can begin to absorb more of the waste plastic that is not being reused, more products must be identified as compatible with recycling and more effective recycling methods must be found.
