How many empty bottles make a ton?

The weight of empty bottles can vary based on their size and material. For example, a standard empty plastic bottle (like a 500ml bottle) typically weighs around 10-15 grams. Therefore, it would take approximately 67,000 to 100,000 empty plastic bottles to make a ton. For glass bottles, which weigh more (around 300 grams for a standard bottle), it would take about 3,333 empty glass bottles to make a ton.
