A food distributor has empty plastic delivery crates. The crates can be washed and used again, or the plastic can be shredded and melted to make new crates.
Which statement about this is correct?
Washing and using the crates again usually uses less energy because the crates are not broken down and remade
Washing and using the crates again is recycling because the crates return to the distributor
Shredding and melting the plastic is reuse because the plastic remains in delivery crates
Shredding and melting the plastic reduces resource use by making each crate contain less plastic
