The flowchart provides key information abou the process making of alumium cans from waste over a period of six weeks.
Overall, it is clear from the graph that the process consistsof several stages, starting with the collection waste by truck and ending with the production of new cans. In addition, the initial stages involve depositing, washing and crushing the waste, whereas the final stages focus on processing, cleaning, heating and moulding the materal into cans.
Accourding to what is shown, the first step is to collect waste and transport it by truck to a factory, where it deposited. It is then washed with water before being crushed. After that, the cruched material is processed and cleaned using chemucals.
In terms of latter stage, the cleaned material is heated in an oven and then moulded material is subsequently weighted using a special machine before being rolled into sheets. Finally, these sheets arenused to produce new aluminum cans.
