Compare Two Processes of How to Produce and Recycle Glass Containers The diagram compares the processes of how to produce and recycle glass containers. Overall, there are some sort of preparations before melting in the glass recycling process, while glass production need to mix various kinds of other chemicals prior to melting. The material used to produce glass is the mixture of sand, soda ash, limestone and other chemicals. But the used glass is the raw material in recycling glass. After collecting the used glass, classifying the glass by color and cleaning including washing and removing impurity are necessary in cycling glass, while there is no such step in container production. While the melting step of glass recycling needs to crush first and then melting, glass production has to melt the mixture at temperature approximately to 1500 centigrade degree. And also there are some differences in shaping between the two processes. Glass container is shaped by blowing the molten glass in glass production process, while glass recycling process mounds the glass into new products after melting the glass.
