Model answer

Band 8 sample answer

Band 8180 words. Every figure in the answer comes from the chart above.

The provided diagram illustrates the lifecycle of plastic products, highlighting two primary pathways: a linear disposal route and a circular recycling process. Overall, it is clear that while some plastic waste is discarded into landfills, a significant portion can be recovered, processed, and reintroduced into the consumer market.

In the linear pathway, consumers purchase plastic products from shops and use them. Once these items are discarded as bags and rubbish, they are transported directly to a landfill site, where they remain as waste. This represents a terminal point in the product's lifecycle, contributing to environmental accumulation.

Conversely, the recycling pathway begins when plastic bottles are collected from consumers. These items are then transported to a sorting house, where they are organised. Following this, the sorted materials are driven to a processing facility. At this stage, the plastic is transformed back into raw products, which are subsequently delivered to shops, thereby completing the cycle. This circular system demonstrates how plastic can be repurposed, reducing the reliance on landfills and promoting a more sustainable approach to material management within the consumer economy.
