You can absolutely make good compost without worms. Worms, like some other organisms, are one type of decomposers in the natural system. There are many others like good bacteria, useful enzymes that can help with the breaking down process. The best thing of all is that we won't see them wiggling around like worms do (if you're scared of this movement). Many of these microbes are invisible to the naked eyes. Besides, some types of worms are not really great for composting.

Here are some ideas to get started:

Way #1: Thermal composting

For thermal composting (aka aerobic composting), we are using the heat generated by the microbial activity to help with the decomposing. The pile can get up to 150F (65C) when the little organisms are most active. You don't need worms to do the work because in this case an army of little microbes will get it done for you.

For this, you'll want a lot of air and oxygen. With an abundant supply of oxygen, the bad microbes will be pushed further away & the good microbes will have room to grow. Basically, we'd want 3 things for thermal composting:

  • Food
  • Air
  • Moisture

In a bin, you can mix in around 3 parts brown & 1 part green or layer them one by one on top of the other. The key thing is not to press your pile down too much. Because the compaction may push out & leave little room for air exchange in and out of the bin. You can turn the compost once a week or every other week to help with the oxygen & heat generation.

Decomposing with good air & heat can take around 3 months. With less oxygen & heat, it may take around 6-12 months especially when the weather is cooler. The lower temperature may cause the microbes to be less active & go into hibernation mode.

Once the compost is done, you'll see some black, crumbly soil that smells nice & earthy. The initial food scraps will be broken down & will no be longer visible. This is good compost to use to start your garden beds or grow some chemical-free yummy veggies.

What to put in the compost:

Good Not suitable
veggie peelings tins
uncoated junk mails glass
uncoated cardboard plastic
egg carton meat scraps
brown leaves cooked foods
hamster bedding cat litter

Here are some browns & greens ideas:

Greens Browns
young tender leaves dry leaves
banana peels straw
kale cardboard
apple wood shavings
carrot sawdust
tomato carbon-rich stuff

Let's check out another way you can compost without worms:

Way #2: Cold composting

In cold composting (aka anaerobic composting), we'd want to do the opposite of thermal composting. With this composting style, we want to trap the oxygen out & let the food scraps ferment inside the bin.

The advantage of this method is that it helps keep the nutritional value of the original stuff. Because there is little to no heat generated during this process. It won't transform the good bits but just break them down smaller. This method is also more commonly known as bokashi composting.

For this, we'll need:

  • Food
  • Bokashi bran

The bokashi bran are the spent beer or rice grains that they've inoculated the good anaerobic microbes strains. These are the guys that will help with the fermentation process.

To make this compost, sprinkle some bokashi bran at the bottom of the bin. Then put in your kitchen scraps. For every 3-4 inches of scraps, sprinkle in some more bokashi bran. It's better to put in more bokashi bran that what it seems needed. We don't want the scraps to give off a putrid smell.

While putting the food waste in, make sure you press the layers down as tightly as possible. This is to push the oxygen out so the anaerobic microbes can do their work. Finally, seal the bucket with an air-tight lid. Then, put the bucket somewhere with shade. After about 2-4 weeks, you'll have some good compost that you can use for the garden.

You can use some of it as mulch, or bury some into a trench or garden bed as fertilizer or for further decomposing. If there's liquid in the bucket, pour it out. You can dilute that liquid to use as a compost tea. It strengthens plants, prevents diseases & builds the fertility of the soil. The concentrated liquid can be used to flush down toilet to fix any clogging issues. The liquid will help decompose any materials that may be clogging up in the pipes.

What to put in the bokashi: you can basically put in any organic materials in this compost that we normally don't put in the hot compost method.

  • Bones
  • Egg shells
  • Meat scraps
  • Cheese
  • Cooked foods
  • Citrus/onions

The best thing of all is that we don't have to worry about the smell. The microbes will ingest it all. Even if we let some air get in, these little creatures will still survive because they are aerotolerant. They can protect themselves in the presence of reactive oxygen molecules.

If you put watermelon rinds in, it's good to dry them a bit because the rinds are a bit watery–similar with other fresh fruits or veggies. We don't want the solids to be sitting in liquid or too much moisture because it may cause an unpleasant odor.

Bye worms & let's go compost

As you can see, there are other good ways to compost without worms. Now that we have some ideas for hot & cold composting, let's get our bins started and go compost. You won't be disappointed & will get super good veggies in your garden beds or plants. It's a truly fun & rewarding process. Have fun.
