Edinburgh residents can put eggs shells in their household or on-street food waste recycling bin (see FOOD WASTE). Or if you have a compost bin at home you can crush the egg shells and add them to the pile to reduce acidity (they contain a small amount of lime). Egg shells are very good for your home compost as they also contain calcium and other minerals (see COMPOSTING).Egg shells contain a small amount of lime. Crush and add to your compost bin/heap to reduce acidity.
Crushed egg shells can be put around the base of tender plants. This may help to deter slugs and snails.
