The Best Compost Machine Shopping Guide

Woman saving food scraps for composting.

How do you select the best compost machine for your home? There are many factors to consider, so you should ask yourself some important questions to determine the right fit.

How much food waste does your household produce daily? Do you plan to operate your new compost machine indoors or outdoors? How will you use the compost once it is finished?

Once you have a better idea of your goals, you can more easily nail down exactly what you need. Explore the following key features to help you choose the best compost machine for you.

Capacity

Electric composters come in various sizes, ranging from tabletop kitchen devices to giant industrial compost machines. You must evaluate how much waste you produce each day to get the right product for you.

If you only plan on composting kitchen scraps, a compact indoor machine might suit you well. The capacity of such a device is about a gallon, which is just enough to break down one day of food scraps for a few people.

Are you an avid gardener or homesteader? If so, you might generate more green refuse than you can process in an indoor composter. In this case, you should explore high-capacity, outdoor compost machines.

Outdoor electric composters are generally much larger than their kitchen counterparts. These electric tumblers also take longer to complete the composting process than overnight tabletop devices.

Speed

Traditional compost piles take around a year to produce rich fertilizer. Improvements in technology enable us to speed this process up using heat and agitation.

Many homesteaders use the best compost tumblers to reduce this time to a couple of weeks. This is an inexpensive way to harness solar heat and a little elbow grease to break down green waste.

Compost machines take this to the next level using electricity to generate heat and power motorized augers. The top kitchen composters can break down a gallon of food scraps in just a few hours.

This high-speed processing leaves you with a different final product than traditional methods. Instead of compost, it generates a dehydrated substance called pre-compost. Pre-compost is still a useful substance, so keep reading until the end to learn more.

Odor

If you are familiar with compost bins then you know they don’t always smell pleasant. You might balk at the idea of keeping your compost inside, for fear of stinking up your whole house.

You don’t have to worry about strong odors when using the best compost machine. These ingenious devices are engineered to break down waste without emitting any noticeable smell.

This feat is achieved through consistent airflow, steady heat, advanced filtration systems, and sturdy seals. This is so effective that many users are comfortable operating their composters right in the kitchen.

Different Composting Methods

The end product is another critical factor you should consider when purchasing the best compost machine. Depending on which type of electric composter you use, you may get moist humus or dry pre-compost.

This distinction is important when you are using homemade compost as fertilizer. Pre-compost has fewer nutrients and lacks microbial activity, but it can be further processed through other composting methods.

For the best results, sprinkle this dehydrated pre-compost mix into your vermicomposting bin. You might also consider fermenting it using the bokashi technique.

If you want a simple solution, you can mix pre-compost into garden beds and allow it to rehydrate and break down in place. Alternatively, you could simply add it to outdoor compost piles with leaves, twigs, and worms to finish it.

True composting is a biological process that requires moisture, air circulation, beneficial microbes, and time. If you want the best compost machine that produces real compost, you need the number one electric tumbler from beyondGREEN.


Compost Machine FAQ

A man collecting kitchen food scraps for composting.

How does an electric composter work?

The rapid electric compost machine is a relatively new household technology. These devices work much differently than other composting methods like bins and tumblers.

Electric composters quickly break down organic material through optimized airflow, steady heat, and constant movement. The refuse is finely chopped and dehydrated to remove bulk and kill odor-causing bacteria.

This process combined with the sealed vessel breaks down waste quickly without any strong odors. These appliances are ideal if you live in an apartment and lack outdoor space for traditional composting.

Rapid compost machines come with a significant tradeoff. The heating process is not selective in which bacteria are killed, so you will sacrifice beneficial microbes.

Helpful bacteria and fungi break down organic waste and excrete the nutrients that plants need to flourish. An outdoor electric tumbler is the best composting machine if you want to preserve this microbiome.

Do compost machines smell?

Traditional composting methods can produce strong smells. Electric compost machines eliminate this issue through carefully designed airflow and filtration systems.

You can minimize any unpleasant compost odor by balancing the ratio of what you add to the mix. This biological process requires two primary ingredients: one part nitrogen and twenty-five parts carbon.

Nitrogen comes from the food scraps you are tossing, and it’s often referred to as green compost. Carbon comes from brown compost, which is dry fibrous material like paper, cardboard, straw, and wood chips.

Carbon helps slow down microbial digestion and absorb excess moisture, reducing the gassy odors green compost gives off as it breaks down. Mixing in additional carbon can reduce the smell of compost machines, tumblers, bins, and piles.

What can you put in a compost machine?

You should only place plant-based refuse in most compost bins. This includes fruit and vegetable peels, stalks, cores, lawn clippings, leaves, etc. You can also add eggshells and most baked goods without any issues.

You might have heard that you cannot compost meat and dairy products. This is only partially true, and you can break animal products down with the right tools.

The best compost machines enable you to toss in these hard-to-compost ingredients and break them down into nutrient-rich fertilizer. By reducing the moisture content and raising the temperature, these appliances eliminate harmful bacteria on animal products.

What are the benefits of organic waste composting?

Did you know that food waste comprises a quarter of the volume of landfills? When all this nitrogen-rich refuse is left to rot, it releases tons of greenhouse gasses in the form of methane.

Composting is different from rotting in that it is a complex microbiological process involving various bacteria, fungi, and animals. These critters consume the waste and excrete balanced fertilizer perfect for growing plants.

Diverting your kitchen scraps from landfills to your backyard is an incredible way to go green and help the environment. That is because this process has the two-fold benefit of reducing emissions and promoting the growth of carbon-sequestering vegetation.

If you live in an apartment or condo, you might not compost due to a lack of space. Luckily, breakthroughs in the best compost machine technology now enable you to do it almost anywhere.

If you are new to composting, you should explore the different composting methods you can try at home. You can finish the pre-compost generated by rapid composters using your favorite technique.
