First of all, we see two informational diagrams over there. First diagram reveals the prosses of the glass production, however we can see how to recycle glass at the second diagram.
It is obvious that there are essential three ingredients of how to product glass. And for the glass recycling, it requires five steps to create new glasses from the used ones.
If we talk about glass production, which is the first diagram, we will see essential four steps. It starts with mixing, which requires sand, soda ash, limestone and other chemicals. Then the second step is melting the mixed stuffs at the deegre of 1500 celcium. When the mixed stuffs melt, we move to the thirtd step, shaping. We shapes the melt glass which we got by melting at 1500 celcium. And for the last step, it requires glass containers.
And turn of the second diagram, which is about of the glass recycling, it requires five steps. The glass recycling is the topic of collecting the old glasses just for the turn new glasses. So, our first step is collecting used glass. Then it needs to sorting by colour, which is the second step. Then the machines washes, or otherwise remove impuruties of the sorted glass, which is the third step of the recycling. After the washing, they start to do fourth step, crushing and melting. Before the recycling is done, the glasses moulding into new products, which is essential and the last step of the recycling glasses. And after the moulding, the recycling of the glass finally done.
