Among the renewable resources on the planet, most people know that waste plastics, waste paper, and waste metals are used by people in their daily lives, and they have a relatively high recycling value. But where did the discarded glass go? Are they worth recycling? Here is the editor of Sinoy Mirror Industry, Angus, to take you through the process of glass recycling!
Everyone is unfamiliar with the recycling of waste glass, because there are relatively few companies specializing in the recycling of waste glass on the market, so everyone doesn't know much about it. However, as a material that has existed and applied for nearly a thousand years in human history, glass products are closely related to our social development and daily life. With the increasing consumer demand for glass products that are closely related to people’s lives, such as the glass packaging of oil, salt, sauce and vinegar that is inseparable from our lives, the sun room for balcony decoration, floor-to-ceiling windows, glass partitions for offices, etc. Glass products have led to an increasing number of discarded glass, which has caused many problems.
There are also glass manufacturers that increase the output of glass in order to meet the growing consumer demand of consumers, but the amount of waste glass generated during production also accounts for a large proportion. For example, in the production process of flat glass, the scrap produced by normal cutting accounts for 15%-25% of the total, and some are produced due to periodic shutdowns, accounting for 5%-10% of the total glass production. How can we recycle such a huge output of waste glass?
Recycling the waste glass itself is aimed at packaging glass containers, such as beverage bottles, beer bottles, etc. If the number of reuses is provided within the validity period, it will not only reduce production costs, but also improve utilization efficiency. do you know? Recycling one ton of waste glass can save 0.58 tons of coal, reduce carbon dioxide emissions by 1.26 tons, and reduce solid waste emissions by 1.16 tons. Taking beer bottles as an example, if one beer bottle is used multiple times, the energy saved can be used for continuous lighting with a 40-watt bulb for 4 hours. According to the editor, 1/3 of the bottles in glass packaging containers can be reused.
At this time, you may have a question? The finished glass containers can be recycled and reused. What about the broken bottles, glass, mirrors, and industrial waste glass fragments? It is gratifying that a major breakthrough has been made in the reuse technology of waste glass fragments in float glass production. A float glass production line in a renewable resource enterprise in Hunan, China has a 90% utilization rate of waste glass. Above, the fuel consumption of the production line is low, the amount of combustion air is small, and the harmful gas emitted is also lower than the standard requirements of the national environmental protection indicators. This production line can recycle nearly 100,000 tons of waste glass every year.
The above is the report brought to you by the editor of Sinoy Mirror Industry.
