Research on the development of ecological glass containers shows that in the process of glass production, every 10% increase in the proportion of waste glass in raw materials can reduce the melting energy by 2.5% and CO 2 emission by 3.5%

as we all know, with the global shortage of resources and the increasingly serious greenhouse effect, the awareness of environmental protection with saving resources, reducing consumption and reducing pollution as the main content has received universal attention and attention all over the world

people call this kind of glass container with waste glass as the main raw material, which can save energy and reduce pollution, ecological glass bottle. Of course, strictly speaking, the proportion of waste glass is required to account for more than 90%

in order to produce high-quality glass containers with waste glass as the main raw material at the same time, the key problem to be solved is how to remove foreign matters (such as waste metal, waste ceramic chips, etc.) mixed in the waste glass and eliminate bubbles in the glass

the research of using waste glass powdering and low-temperature melting technology to realize the identification and removal of foreign matters and the low-pressure defoaming process with the attitude of keeping improving the porosity can be as high as 99.8% has entered the practical stage. The recycled waste glass is undoubtedly mixed in color. In order to obtain a satisfactory color after melting, the method of adding metal oxides in the melting process can be adopted, such as adding cobalt oxide to make the glass light green, etc

the production of eco glass has been supported and encouraged by governments all over the world. In particular, Japan has taken a more positive attitude in the production of eco glass. In 1992, it was rewarded by the World Packaging Organization (WPO) for producing and implementing eco glass with 100% waste glass as raw materials. However, at present, the proportion of eco glass is still low, and even Japan only accounts for 5% of the total amount of glass containers in the Japanese Standard JIS B773

glass containers are traditional packaging materials with a long history, which have been closely related to people's lives for more than 300 years. It is safe to use, easy to recycle, and will not pollute the contents or glass

as mentioned at the beginning of this paper, it is also facing serious challenges such as polymeric packaging materials. Therefore, how to strengthen the development of new glass manufacturing technology and give full play to the advantages of glass containers is a new topic facing the glass container manufacturing industry. I hope the relevant technical developments introduced above can provide some useful references to the industry
