The illustration demonstrates the cycle of manufacturing household products from plastic bottles.
Overall, there are nine steps in the sequence, starting with plastic stuffs being thrown into bins, followed by making small plastic pieces and ending with producing end products.
The first five stages show the transformation of primary material. Initially, rubbish is disposed of into bins, before being collected by a night-cart. Then, trash is brought into waste treatment plant, where sort the plastic bottles from the total rubbish. Subsequently, the collected items are conveyed into a machine to be compressed into blocks, which are washed in water after being chipped into small pieces.
The remaining steps make recycled products. After being cleaned clearly, the small plastics are masticated into plastic pellets, which are heated at an intense temperature to form raw materials. After that, these fabrics are utilised to manufacture household stuffs, including plastic bottles and reusable clothes or bags. Finally, these products are made use of by customers for a long time, prior to being thrown to the bins, renewing the cycle.
