A drinks company must choose one material for its bottles. Table shows data about three materials.
Table: The energy needed to produce one bottle, the percentage of bottles that are recycled, and the mass of one empty bottle, for three materials
| Material | Energy needed to produce one bottle in kJ | Percentage of bottles that are recycled (%) | Mass of one empty bottle in g |
|---|---|---|---|
| Aluminium | 630 | 75 | 15 |
| Glass | 780 | 68 | 210 |
| Poly(ethene) | 290 | 12 | 25 |
Use Table. Calculate the energy needed to produce 1000 aluminium bottles.
Use Table and your own knowledge. Evaluate which of the three materials is the most sustainable choice for the company's bottles.
