Garbage classification and recycling tipsGarbage sorting and recycling tips
wood is the main source of paper fiber. Each manufacture 1 tonnes of paper (approximately equivalent to 5,000 copies) costs 20 Ke 8 meters in height, diameter 16 cm logs, each tree to grow to average about 20 years to 40 years. Logging in virgin forests may cause difficult to reply to the destruction of ecological environment and, therefore, best paper wood from well managed commercial forests to ensure the sustainable use of forest resources and the maintenance of ecological balance. About 1 kg of paper required 2.7 kg of wood, 130 g of lime, 85 grams of sulfur, chlorine and 40 g 300 litres of water and chlorine bleach is in the papermaking process, the main sources of water pollution. Therefore, the use of paper, using recycled paper, try using unbleached paper, will help to the environment.
waste paper is generally divided into kraft paper box mixed paper, newspaper, white paper, four categories. Recycled waste paper to the Antiquities Dealer or recycling back tail, will be sent to the market of waste paper packaging classification, then sent to paper mills after beating after Deinked, paper, dry, made of recycled paper. Taiwan in a variety of paper products, most of them recycled paper content. Using waste paper to paper than wood pulp 75% reduction in air pollution, water pollution, 35% water 40% energy consumption and reduce waste.
Taiwan lack of metal raw materials, most of the metals imported raw materials or waste recycling. Metal ore exploitation will damage to ecological environment and landscape, metal smelting consumes considerable energy and resources, and water and air pollution. Commonly used metal containers for the iron and aluminum cans, they are made of tinplate and aluminum skin.
Tin and aluminium cans are recycled separately from the first step. Cans are usually hard and joints can be easily identified. Recovery of iron and aluminium in the Recycle Bin are compressed into blocks, then sent to the chain steel or aluminum melting plant and made of steel or aluminium, and complete the life cycle of steel and aluminum cans. Made from recycled aluminum cans to aluminium, bauxite 82% less energy consumption and 85% of air pollution, water pollution and 90% of waste. Made from recycled cans to iron using iron ore to reduce the 52% of energy and 68% of air pollution, water pollution and 95% of waste.
products derived from petroleum. The extraction, transport and refining of oil, consumes a lot of resources and energy, or some degree of impact on the environment. Commonly used plastic containers made of six categories, namely 1. PET (plastic bottles) 2.HDPE (shampoo bottle) 3.PVC (water bottles, detergent bottles) 4. LDPE (milk) 5.PP (milk bottle) 6.PS (Yakult bottle, styrofoam tableware).
after the recycling of plastic bottles of mostly rely on artificial categories. And in all kinds of plastic bottles be packed separately and sent to recycling plants, after crushing, washing, drying process, to make secondary plastic raw materials. These materials can be used to make all kinds of plastic products. In PET, for example, use of recycled secondary materials than with raw materials can reduce the 50% energy and 60% of air pollution, water pollution and 90% of waste.
raw material of glass is silica sand, Placer mining without erosion, resulting in destruction of the landscape and soil erosion. Manufacturing glass considerable energy and resources consumption, also have a water and air pollutants.
bottle should be washed before you dry, avoid the risk of breaking. Recycled glass if transparent, green, brown color to better classification. Fluorescent lamp, light bulb, glass, mirrors, China dishes because it contains hazardous substances or other ingredients not mixed and bottles recycled. Recycling glass bottles after sorting, crushing, after decontamination, was sent to the glass furnace to manufacture new glass products. Use recycled secondary materials than the materials used to make glass to save 38% energy and reduce the 50% of air pollution, water pollution and 90% of waste.
a lot of production and consumption activities, resulting in a lot of junk. According to EPA statistics, Taiwan in 1994 removal of 8.46 million tons of household waste, which is equivalent to manufacture 1.104 kg of garbage per person per day, spam and an annual growth at a rate of 5%. Garbage if not properly handled, will affect environmental health, harm our environment.
the first step in solving the garbage problem, is to reduce spending in order to reduce the generation of waste.
the second step is repeated as much as possible to use the product, extending the life of products.
the third step is to recycle, recycle.
unable to recycle recycling rubbish, to sanitary burial process. Garbage, 40% is a resource that can be recycled. Therefore, the recycling in addition to reducing waste, reduce environmental pollution, the significance of a more sustainable use of resources.
