Inspired by conversations on the FOOD52 Hotline, we're sharing tips and tricks that make navigating all of our kitchens easier and more fun.
Today: we're sharing three different ways to compost your kitchen scraps.
Composting scares many of us the way that baking bread does: it requires us to follow certain rules, use our best judgement, and leave the rest to science (and perhaps adding in a few prayers to the homemaking gods for good measure).
And, while the virtue of composting is clear -- it reduces waste, and it gives valuable nutrients back to the soil -- the alternative is often too easy: the onion is chopped, the banana peeled, and your waste goes into the trash.
But composting can be easily integrated into your life, whether you have a vast yard or a closet-sized apartment. Even the laziest of us can do something useful with our organic food waste. And we're here to tell you how.
First: The quick and dirty on composting
Composting is a natural process in which organic matter breaks down into fertilizer with the help of the microorganisms in soil (or, as we'll discuss later, earthworms). This resulting soil, which passionate gardeners often call "black gold" and Martha Stewart sweetly describes as having the texture of "crumbled chocolate cake", is rich in nutrients, and will help retain moisture when added to your garden beds or potted plants. (Fun fact: the scientific name for that "black gold" is humus.)
The right materials
There are a few things to avoid adding to your compost bin or pile. These include the thick rinds of citrus, fats or lard, ash, pet waste, and dairy. A comprehensive list of what's cool to compost and what isn't can be found here.
Once you have the right scraps, your options for composting can be organized in three categories:
At its most basic, aerobic composting requires only carbon, nitrogen, air, and water. The nitrogen comes from "green" materials such as food scraps, grass, and garden trimmings, while the carbon comes from "brown" materials such as fall leaves, straw, and shredded paper. Keeping these different factors in balance is important -- a reliable ratio is two parts green to one part brown, and they should be added in alternating layers to a compost pile.
If you're lucky enough to have a yard, you can easily keep a compost pile. There are a number of ways to do it, but they all require a few basic tools and practices. Find a shady, dry spot; collect and add your food scraps; add water, turning occasionally for proper aeration. Cover with a tarp if you live in an especially hot or rainy area. Celebrate your resulting humus (maybe by eating some hummus?), and add it to your garden. For comprehensive instructions, turn to the EPA's composting website.
If you don't have a yard but you're still committed to aerobic composting at home, there's hope for you yet -- you just need to enlist the help of some industrious worms. Vermicomposting is becoming increasingly popular in urban areas; if you're interested, take a look at this handy how-to graphic.
Also known as Bokashi composting, anaerobic composting doesn't require oxygen, water, or even walking outside. With an aerobic composting system -- we like the Urban Composter Bucket (pick one up in our shop!) -- you simply add your kitchen scraps to a bucket, drain off excess liquid as your scraps decompose, and wait a few weeks for nutrient-rich fertilizer. These buckets are a clean, smell-free way to compost in the comfort of your kitchen -- and they are essentially fool-proof.
If you don't have any use for fertilizer, or you know that composting just isn't going to happen for you right now, you still don't have to throw away your banana peels and egg shells. Your local farmers will be delighted to take organic food scraps off of your hands -- and you'll be contributing to the bounty you'll be buying from them next season. Many cities have drop-off programs for compostable material; search for one in your area, or simply offer up your scraps to the man selling you that rutabaga. You'll probably make his day.
