Calculated using values provided for tyres disposed, waste paper generated, oil recycled and oil spilled.

Number of tyres disposed = 1113 (using an average of 100 lbs per truck tyre, I arrive at a value of 50530 kgs for tyres (1 lbs = 0.453 kg) (page 49, graphic)

1315 kg of paper, glass and plastic were recycled (page 48 2nd paragraph under waste management)

31500 litres of oil were recycled (using a density of 881 kg/m3 for petroleum oil, I arrive at a value of 27750 kg of oil) (page 49 graphic)
