6 best continuous composters

Continuous composters are a type of composting system designed for convenient and ongoing composting of organic kitchen waste in a home setting. These composters are specifically designed to make composting easy and accessible for individuals or families interested in reducing food waste and creating nutrient-rich compost for their gardens.Here are some key features and information about continuous composters:

  1. Continuous Composting Process: Continuous composters are designed to allow users to continuously add kitchen scraps and organic materials to the composting system without the need to stop or wait for batches to finish composting. This means you can add scraps daily and harvest compost as needed.

  2. Aerobic Composting: Most continuous composters use an aerobic (with oxygen) composting process. They provide good aeration to facilitate the decomposition of organic matter by beneficial microorganisms, leading to faster and odor-free composting.

  3. Compact Design: These composters are typically compact and designed to fit easily in a home kitchen or outdoor space. They are often designed to be odor-free and pest-resistant.

  4. Material Quality: Continuous composters are usually made from high-quality, durable materials such as plastic or stainless steel. This ensures their longevity and makes them easy to clean.

  5. Dual Chamber System: Many continuous composters have a dual-chamber design, with one chamber for active composting and another for maturing compost. This allows you to continuously compost while the first chamber finishes maturing.

  6. Odor Control: Good continuous composters have effective odor control mechanisms, such as airtight seals and carbon filters, to prevent unpleasant odors from escaping.

  7. Maintenance: Regular maintenance is typically minimal, involving occasional turning or mixing of the compost and ensuring a proper balance of green (nitrogen-rich) and brown (carbon-rich) materials.

  8. Harvesting Compost: When the compost is ready, it can be easily harvested from the matured chamber, leaving the active chamber to continue composting.

  9. Compost Uses: The resulting compost can be used to enrich garden soil, potted plants, or indoor houseplants, providing valuable nutrients and improving soil structure.

  10. Environmental Benefits: Using a continuous composter can help reduce the amount of organic waste sent to landfills, thereby reducing greenhouse gas emissions and contributing to a more sustainable lifestyle.

Overall, continuous composters offer a convenient and environmentally friendly way to recycle kitchen scraps and organic waste, turning them into nutrient-rich compost for gardening and reducing the environmental impact of organic waste disposal. They are a great addition to home sustainability and composting efforts.

User questions & answers

Question: How much do these things smell? Want to put composter inside a small area behind our shed if the smell won't nauseate the kiddos
Answer: We have one in our backyard and I almost never smell it. The only time I have noticed a smell has been when the lid is open and I am dumping more kitchen scraps in it and even then it's not that often. All the compost books say if it does smell bad that means you need more greens or browns depending on the smell.
Question: What is the capacity
Answer: According to the calculator, 12 cubic feet equals almost 90 gallons--if you're mixing your nitrogen to carbon ratios using 5 gallon buckets. This looks like an excellent explanation for how to fill your composter: https://savvygardening.com/compost-how-to-guide-based-on-science/
Question: Since it doesn't have a bottom, will that work on our patio? We live in a condo and only have a large patio area that is concrete
Answer: I wouldn't use this in your situation. It would definitely stain the patio. I'd find a different design. Also you'll need to make sure you have enough dry material in the composter or it will stink if your compost is mostly kitchen scraps. In your situation I'd probably go for worm composting. My daughter made a vermicompost kit out of a couple of inexpensive storage bins at a camp a number of years ago. One has holes drilled into it and the other is solid so any worms or leakage will go into the outer bin. Here is an article on the subject: http://compost.css.cornell.edu/worms/basics.html You need to get red worms or red wigglers from a bait store, not common earth worms from the soil for best results.
Question: How do the top doors open? Easy enough to do one handed? Do they keep out the raccoons
Answer: I have not had any problems with raccoons or rodents at all. The top locks tightly. And yes, I can open it one handed to throw in a small amount of scraps but otherwise, two hands work better to take the entire top off when adding large amounts, leaves or twigs and grass clippings. Remember to turn it at least once a week - I use a pitchfork to do that task. Good luck!

Composting: Help Yourself and the Environment at the Same Time

The composting trend is growing and the most recent research shows that In 2012 the U.S recycled and composted almost 87 million tons of municipal solid waste. This saves more than 1.1 quadrillion Btu of energy; that's the same amount of energy used by 10 million households in one year.

Over 19 million tons of yard trimmings were composted in 2012, which is 5 times more than in 1990.

Food waste is the single largest type of item thrown away making up 21 percent of everything we throw out. We might as well use this food waste to fertilize our gardens rather than paying to have it sent to a landfill! The Soil Savers extra large capacity make it perfect for accommodating a good deal of food scraps.

Access Your Compost Easily

Dual hatch doors allow you convenient access to your compost whenever needed.

The Advantage of SoilSaver Bin Composting

The items you put in first will be at the bottom and should be the first out. This is a big benefit because you can use a little compost at a time if you need to. This is an advantage compared to most tumbling composters. With many tumbling composters, all the old scraps are mixed with the new waste which means all of the compost in the bin needs to be ready before you can use any of it.

More Advantages of the Best Compost Bin

The slots and louvers throughout the compost bin let air in and out for aeration which helps food waste break down quickly into rich compost.

The 0.200" thick resin walls provide excellent strength and durability.

The extra large 12 cubic foot capacity means you will have plenty of space for your compost waste

Lid is easy to open and lock making it convenient to add to your composter while keeping animals out

A Sense of Humus goes Well with Compost

A simple to follow yet comprehensive guide helps you put the right food waste and yard trimmings into your composter.

User questions & answers

Question: What are the size openings on the doors at the bottom
Answer: The FG20P Backyard Compost Thermometer is made in China. We do offer US made thermometers, search for Reotemp Heavy Duty Compost Thermometer. -Peter Reotemp
Question: So how do you turn the pile with a bin like this
Answer: Yes! The dial is hermetically sealed (waterproof).
Question: it obviously has an open bottom for easy access for the worms.... right
Answer: Yes. that is what I use them for and they work really well. I locate the bales that are the hottest and leave the REOTEMP in the bale and look at it daily. My last hay was not as dry as I would have liked and I put the REOTEMP in when it read 120F three days after baling. It went to 140F and then came back to 120 when I removed it yesterday.
Question: Can you anchor it to the ground? Can animals easily take the top off
Answer: The sensitive portion is the last 2 inches at the tip of the probe. So you don't have to necessarily put the entire stem into the compost pile.

User questions & answers

Question: what is the best mixture of scraps to put in the composter to start the first batch in a brand new yimby tumbler composter
Answer: Yes it does. It does not come with a mat.
Question: Any tips for winter usage, once temperatures cause the compost to freeze
Answer: Yes, if you print a cake on a shirt and make decorations for it then you could use it for cake decorating purposes
Question: do you have to put it together and is it difficult we are not good at assembly
Answer: I use a teflon sheet and no you don't have to press too hard. I used to use my iron and this thing is AAAAAmazing!!! Time and heat control... no more guessing or over heating.
Question: Is it bear proof
Answer: Your iron may be greatly superior to mine...But the advantages that this heat press has over my iron are these: 1) I'm able set the exact temperature I need. (I didn't realize what a difference this would make!) 2) The heat press is HEAVY. I want a lightweight iron for ironing clothes, but want pressure (which weight provides) for heat transfer designs. 3) This heat press has a timer. I've been amazed how much better my work turns out when I'm a little more careful about the timing. These are the three major advantages I've found in using a heat press over my iron. To be truthful, any heat press probably delivers these. But the smaller, more compact size (even with the largest, the 12 x 10--which I purchased), and hence, easier storage when not in use...is what tipped the scales for me when choosing the Cricut over the other brands of heat presses. Hope this helps your decision-making!

User questions & answers

Question: Do you have to add straw or any carbon ratio or is it just food waste
Answer: This works very well for a composter. Easy to put together.
Question: Is the plastic BPA free
Answer: Yes. There are indent places as handholds to help roll it on its base. I like my 2.
Question: Can I get some assembly instructions or a link please
Answer: 6 x 10 inches
Question: Has anyone had this long enough to get usable compost? If so, would you recommend it for someone who has never done composting before
Answer: My unit opens very easily. I have to clear the door occasionally of small debris that collect in the track the door uses. If yours was difficult to open day one use some sand paper on the door ( bottom and top edge) and / or the main unit track (to remove any plastic molding leftovers). This could solve the problem and be easier on you than a return. If no amount of removing burrs etc. helps the situation then a return may be necessary. Mold injection plastic is notorious for having to have its edges cleaned up a bit. This often is not done as much as is needed at the end of the manufacturing process. I regularly have to finish the job on plastic mold injection products. I love my unit. It is the perfect size for my porch and for me to pick up and empty. It does spill out small particles through vent holes... something one needs to expect and understand as part of the design.
