A recycling company processes 50 tonnes of waste glass from food jars each month. The company is considering two recycling routes.
| Route | Process | Energy used each month in MJ | Recycled material produced each month in tonnes | Price paid by buyers in £ per tonne | Maximum amount buyers will purchase each month in tonnes |
|---|---|---|---|---|---|
| S | Sort by colour, then melt to make new glass products | 240 000 | 44 | 96 | 70 |
| M | Keep the colours mixed, then crush for use in road surfaces | 15 000 | 48 | 28 | 25 |
Evaluate whether the company should use route S rather than route M. Use the data in the table.
