Glass bottles are indeed a more environmentally friendly packaging method, mainly for the following reasons:
1. Reusable and recyclable: Glass bottles can be washed and disinfected repeatedly before being reused, thereby reducing the consumption of new glass raw materials. Even if it is ultimately scrapped, glass can be 100% recycled and reused without generating any waste.
2. Degradability: Glass is made from natural minerals and does not contain any harmful chemical components. It can be completely degraded in nature without causing pollution to the environment.
3. Clean production process: The process of manufacturing glass bottles is relatively simple, does not require the use of large amounts of chemicals, and has low energy consumption and greenhouse gas emissions.
4. Non polluting and non-toxic: The glass itself does not contain any toxic or harmful substances, and will not penetrate into the filled products, ensuring the hygiene and safety of the product.
The recycling production process of glass bottles mainly includes the following steps:
1. Recycling of waste glass: Waste glass collected from daily life and industry undergoes pre-treatment such as cleaning and classification.
2. Processing and melting: Add an appropriate amount of raw materials such as quartz sand, calcium stone, sodium carbonate, etc. to the pre treated waste glass, and melt and fuse it at high temperature.
3. Manufacturing and Forming: Molten glass can be molded into new glass products through blowing, casting, and other methods.
4. Annealing treatment: In order to eliminate internal stress, the glass products made need to undergo annealing and cooling treatment.
5. Packaging inspection: After visual inspection and packaging, it can be put on the market for sale.
Throughout the entire process, whether it is raw material preparation, melting processing, or forming annealing, clean energy is utilized as much as possible, and multiple environmental protection measures are taken to minimize energy consumption and pollution emissions. Therefore, glass bottles can be considered a highly environmentally friendly packaging material.
