The final intervention takes this idea a step further by designing the sleeve to feature a waste section for used butts, thereby providing a solution for to smokers throw them away. One issue is the lack of bins for butts, there are some products for smokers to buy such as portable ash trays. However, most people can't be bothered to buy them or simply aren't aware.
This sleeve centres around a storable compartment to store their fag ends, which can been thrown away when the packet is finished. The compartment is foil lined to stop the butt burning the package. It uses a push mechanism for easy access and is designed with a maximum opening distance to avoid spilling its contents.
