What is the profit margin for recycling waste circuit boards

　　Circuit boards are common components in many electronic products, and are also present in commonly used household appliances. Nowadays, electronic products update and iterate very quickly, and the elimination rate is also high. Once electronic products are eliminated, they will become waste. According to statistics, the total amount of electronic waste generated annually in China is over 8.2 million tons, which is a very large quantity. And its metal content is dozens of times that of ordinary mineral metals, making it a good raw material for collecting and extracting metals. Some even turn waste circuit boards into "urban mines".

　　Some people may not be particularly familiar with circuit boards, which contain up to 40% metal, with copper accounting for a higher proportion, as well as gold, aluminum, nickel, lead, silicon, and other metals. Often, circuit boards are broken, crushed, and sorted using circuit board recycling equipment to extract metals for sale, resulting in substantial profits.

　　One ton of waste circuit boards contains 13% copper, 0.145% gold, and other metals. As for how much money can be earned from processing one ton of waste circuit boards, a clear answer cannot be given immediately. It will be influenced by many factors, such as the metal content of waste circuit boards, daily processing volume, equipment loss and depreciation, etc. However, what can be confirmed is that the benefits obtained from recycling waste circuit boards for processing are considerable.

　　Taking the integrated IC of central air conditioning as an example, currently, it is a highly recognized waste commodity. The recycling price per ton is within 170000 yuan, and the total amount after refining reaches 800000 yuan, with a net profit of at least 400000 yuan. The profitability of this industry lies in the cost price of recycling and the difficulty of gold purification technology.
