Are you planning to take part in plastic-free July, a global initiative designed to help people reduce their use of single-use plastics? If so, these tips from marine scientist and cookbook author Finn Ni Fhaolain should be really helpful. Shop loose as much as you can - think bread, fruit and veg. Bring your own bag to the shop, and buy glass jars, which you can keep and use for storage containers. Tin is recyclable, as are cardboard and paper (they can also be used for gardening etc).
