If you throw whole eggshells into your compost heap you are likely to get small pieces of egg shells in the finished compost: not ideal. Manually crushing up your eggshells before you throw them into your compost pile will help them break down faster and more completely. See the following pictures:
|I save a bunch of old egg shells in the fridge and grind them all at once.|
|I use a large mason jar to crush the egg shells. The dry shells should break easily.|
|Crush, crush, crush!|
|It only takes a minute to crush up all of the eggs.|
It is mid January, which means we have another two months or so before 'compost season' opens. Even in winter you can be improving your compost skills and planning for next spring – make sure you are saving the ash from your fire place and eggshells from breakfast!
Interestingly, the same thing can be done to your eggshells if you want to feed them to your backyard chickens. If you crush up your eggshells really well, you can add them to your chicken feed and recycle the calcium. Recycling = Living Lighter on the Land
