An Overview of Common Scrap Material

//An Overview of Common Scrap Material

During our life time, we may produce over 600 times our own weight in trash.If we don’t recycle them, we will undertake unimaginable result in future. Pretty much all the resources we have on Earth- all the raw materials and an awful lot of the energy- are limited. Once we’ve used them up, we won’t get any more. The other hand, the things we throw away are likely to go off to be bulldozed underground in a landfill or burnt in an incinerator. Both of two ways will bring horribly pollution. Therefore, it will be good for us to take part in reducing, reusing and recycling as much as possible.

What can be recycled? Most things you throw away can be recycle and remade into new products- although some are easier to recycle than others. Metal, plastics, paper and cardboard, kitchen and garden waste, wood, etc.,all can be recycled.

Metal Scrap
One section of the recycling industry may not be popular, but just as important is scrap metal recycling. Why to recycle metal scrap? Simply put, recycling scrap metal is vitally important to the environment and the economy. Another good reason is that metal is one of the most easily refashioned and reused materials we have.

We all know that scrap metal is divided into two categories: ferrous and non-ferrous. Ferrous metals include carbon steel, stainless steel, cast iron, and wrought iron, and those often used in housing construction, cars and trucks, and rail roads. After recycled, they are also being extensively used in these industry.

Non-ferrous metals include copper, lead, brass, aluminum, tin, zinc and others. Copper scrap is more familiar with us. The usual commercial supplies of pure copper are used for the most critical of electrical applications such as the production of fine and superfine enamelled wires. When these copper wire scrap is no longer in use, they can be recycled and refined. Copper cable granulator and wire stripping machine are two common choices.

Paper is made from plant fibers. Every time when it is re-manufactured, the fiber will become shorter. When they are too short to make paper, some new paper always has to be added during the papermaking process according to the practice. Another problem with recycling paper is that not all paper is the same. Among all kinds of paper, you will find thatoffice paper is better than the toilet paper. The higher the quality of paper waste, the better the quality of recycled products it can be used to make. So high-grade white paper collected from offices can be used to make more high grade white recycled paper. But a mixture of old newspapers, office paper, junk mail, and cardboard can be used only to make lower-grade paper products.

Of all the different waste we toss in the trash, plastics cause by far the biggest problem. They last a long time in the environment without breaking down, which can kill wildlife, scar the shoreline and pollute our water.The only trouble is, plastics are relatively hard to recycle. There are many different kinds of plastic and they all have to be recycled in a different way. However, there are also some plastic recycling machines which are applicable for many kinds of plastic scrap like PVC, TPR, PP, PE, EVA, PET, PC, TPE materials, waste rubber products, sponge, etc.

Kitchen and Garden Waste
Food waste sealed in a plastic bag on a landfill site doesn’t decompose properly. Instead, it produces methane, a greenhouse gas, which contribute to global warming, as well as a liquid, leachate, which can contaminate water supplies.

One way to make good use of kitchen waste is composting. This way is easy and requires little time, effort or space, depending on which system you use. The compost is invaluable for the soil in your garden or potted plants: It’s a complete and natural food for the soil, helping to improve its structure, water-retaining abilities and overall health. You also can recycle both kitchen and garden waste if you keep a compost heap or bin in your garden.
