如果地球上的任何人造物品都比塑料袋更普遍,那么它甚至可能是远远不可能的,它必须是铝罐。但与塑料袋不同,塑料袋危及海洋生物并摧毁地球,铝罐实际上对环境有益。至少,如果像你我这样的人花时间回收它们。那么为什么回收铝?那么,作为回答这个问题的起点,这是怎么回事:铝回收提供了许多环境,经济和社区效益;它节省了能源,时间,金钱和宝贵的自然资源;它创造就业机会并帮助支付社区服务,使数百万人的生活更美好。每年在美国销售超过1000亿个铝罐,但不到一半是回收的。其他国家类似数量的铝罐也被焚烧或送往垃圾填埋场。每年全球约有150万吨废铝罐。所有这些被破坏的罐头都必须用完全由原始材料制成的新罐子代替,这会浪费能源并造成广泛的环境破坏。如何无法回收。 在全球范围内,铝工业每年排放数百万吨温室气体,如二氧化碳,这有助于全球变暖。根据集装箱回收研究所的数据,虽然铝罐仅占一吨垃圾重量的1.4%,但与用原始材料制成的新产品替代平均吨垃圾相比,它们占温室气体影响的14.1%。铝冶炼还会产生硫氧化物和氮氧化物,这两种有毒气体是烟雾和酸雨中的关键元素。此外,每吨新的铝罐必须生产以替代未回收的罐头,需要5吨铝土矿,在冶炼之前必须进行剥采,粉碎,洗涤和精炼成氧化铝。这个过程造成大约5吨腐蚀性泥浆,污染地表水和地下水,进而损害人和动物的健康。铝的回收次数没有限制。这就是回收铝对环境有利的原因。铝被认为是一种可持续的金属,这意味着它可以一次又一次地回收而不会损失材料。与现在相比,回收铝的价格从未如此便宜,更快或更节能。铝罐是100%可回收的,使其成为所有材料中最可回收(和有价值的)。如今铝材可以折腾到您的回收箱中,将在60天内完全回收并重新回到商店货架上。
If any man-made item on the earth is more common than a plastic bag, then it may even be far from impossible, it must be an aluminum can. But unlike plastic bags, plastic bags endanger marine life and destroy the earth. Aluminum cans are actually good for the environment. At least, if people like you and I spend time recycling them. So why recycle aluminum? So, as a starting point for answering this question, what is going on: Aluminium recycling offers many environmental, economic and community benefits; it saves energy, time, money and valuable natural resources; it creates jobs and helps pay for community services To make life better for millions of people. More than 100 billion aluminum cans are sold annually in the United States, but less than half are recycled. A similar number of aluminum cans in other countries have also been burned or sent to landfills. There are approximately 1.5 million tons of waste aluminum cans worldwide each year. All of these destroyed cans must be replaced with new ones made entirely of the original material, which wastes energy and causes extensive environmental damage. How can I not recycle. Globally, the aluminum industry emits millions of tons of greenhouse gases, such as carbon dioxide, each year, which contributes to global warming. According to the Data from the Container Recycling Institute, although aluminum cans account for only 1.4% of the weight of one ton of waste, they account for 14.1% of the greenhouse gas impact compared to the average ton of waste made from new materials made from raw materials. Aluminum smelting also produces sulfur oxides and nitrogen oxides, which are key elements in smog and acid rain. In addition, every ton of new aluminum cans must be produced to replace unrecycled cans, requiring 5 tons of bauxite, which must be stripped, crushed, washed and refined into alumina prior to smelting. This process causes approximately 5 tons of corrosive mud, contaminating surface water and groundwater, thereby damaging the health of people and animals. There is no limit to the number of times aluminum can be recycled. This is why recycling aluminum is good for the environment. Aluminum is considered a sustainable metal, which means it can be recycled again and again without losing material. The price of recycled aluminum has never been so cheaper, faster or more energy efficient than it is now. Aluminum cans are 100% recyclable, making them the most recyclable (and valuable) of any material. Now aluminum can be tossed into your recycling bin and will be fully recycled and returned to the store shelves within 60 days.
