A second green box should make it easier as glass can go in one and cans (including aerosol cans, jar lids and foil) can go in the other. It would also be more efficient for the crew when they collect your recycling.
Having a second green box is entirely optional and you can still use the one green box for your glass and cans.
You can order recycling containers for delivery to your home address.
