Almost all local authorities in England have kerbside collections of plastic.

But the Environmental Audit Committee heard England had a "particularly high" level of consumption of drinks in single-use plastic bottles outside the home.

So this suggests a deposit scheme could be a good way of increasing recycling in England.

At the moment, more than 95% of the plastic bottles that are processed for recycling have been collected from households.

What about littering?

There's not much evidence to suggest deposit schemes reduce littering.

The Defra-commissioned research said that although "the general assumption appears to be that receiving a monetary or other reward will encourage consumers to deposit containers at a collection point instead of littering", there was little data to support this.

A German study published four years after its deposit scheme was introduced found no evidence of litter reduction.

Who pays?

This varies and depends on the design of the scheme.
