Apple cores are biodegradable. Is it still littering?
Even biodegradable items such as apple cores and banana skins are litter. These items can make a place look unattractive and disorderly, and can attract vermin. Biodegradable items such as food scraps can contribute to water pollution if these end up in a waterway, by causing algal outbreaks and sucking the oxygen out of rivers as they decay. If you are not able to place food scraps such as apple cores in a compost bin, they need to go in the litterbin. If there is no bin available in the immediate area, hang on to it until you can find a bin. You are just as likely to be fined for littering an apple core as you are for littering a cigarette butt or drink container.
