Best Small Compost Bins for Reducing Waste and Improving Soil

Composting is a simple yet effective way to reduce waste and create nutrient-rich soil for your garden. By using a small compost bin, you can easily manage food scraps and yard waste, turning them into a valuable resource for your plants.

The key to successful composting is to balance the "green" and "brown" materials in your bin. Green materials, like food scraps and grass clippings, are high in nitrogen, while brown materials, like leaves and twigs, are high in carbon. Aim for a mix of 2/3 brown materials and 1/3 green materials.

A small compost bin is a great option for urban gardeners or those with limited space. These bins are designed to be compact and easy to use, making it simple to collect and compost your waste. They're also a great way to teach kids about the importance of reducing waste and recycling.

Storing your scraps in a stainless steel bin like the Simplehuman Compost Caddy reduces the risk of contamination from acidic food waste. This is especially important because acidic contents can leach phthalates out of plastic.

The best size for a kitchen composter is crucial for efficiency and ease of use.

Food scraps have a short shelf life, so it's essential to choose a bin that can hold several days' worth of scraps.

The ideal bin should be large enough to fit in your kitchen, but not so big that it takes up too much space.

A compact bin like the Typhoon Compost Caddy, which holds 84 ounces of material, is perfect for one- or two-person households.

Small compost bins are designed to be compact and space-efficient, making them perfect for urban gardens or small backyards. They're usually around 12-18 inches wide and 24-36 inches tall.

One of the most convenient features of small compost bins is their ability to be placed in a corner or against a wall, taking up minimal floor space. This is especially useful for gardeners with limited room to spare.

The aeration system in small compost bins helps to speed up the decomposition process by allowing oxygen to reach the compost. This can reduce the time it takes for food waste to break down by up to 50%.

Small compost bins often come with a lid that helps to keep pests and rodents out of the compost. This lid also makes it easy to add new materials to the compost pile.

The carbon-to-nitrogen ratio in small compost bins is usually around 2:1, which is ideal for breaking down food waste and other organic materials. This ratio helps to create a balanced compost that's rich in nutrients.

Some small compost bins come with a built-in worm composter, which is perfect for gardeners who want to create a nutrient-rich soil amendment using red wiggler worms. These worms are incredibly efficient at breaking down organic matter.

Hinged lids are a game-changer for small compost bins. They make it easier to add scraps by allowing you to flip the bin open, add your scraps, and snap it shut again.

The SimpleHuman Compost Caddy's steel hinged top is a great example of this design feature. It's also perforated, which helps with airflow and odor control.

A charcoal filter in the lid is another important feature to look for. The Exaco Eco 2000 Kitchen Compost Pail is the only model that includes all three of these features: a hinged lid, perforations, and a charcoal filter.

Smaller particles increase the total surface area that microorganisms can feed on, which is crucial for efficient composting. This is because microorganisms need a lot of oxygen to thrive, and smaller particles provide more surface area for them to colonize.

Chopping up the individual elements of the compost pile with a lawnmower can be effective, but it's not always necessary. In fact, the author has found that they can get by without it most of the time.

The ideal particle size for composting is not specified, but it's clear that smaller particles are beneficial. This is because they allow microorganisms to break down the compost more efficiently.

The author's large compost pile only gets turned twice before use, but this is not always the case. Some experts, like No Dig expert Charles Dowding, only turn their compost heaps once before use.

Hinged lids make adding scraps to your compost bin a breeze. The Epica and Typhoon bins have lids that open like a cookie jar, making it easy to add food scraps. However, this design can be messy, as you need to find a place to set the lid.

A hinged lid is a game-changer, allowing you to flip the bin open, add your scraps, and snap it shut again. I can see why this design would be preferred by many users. The SimpleHuman Compost Caddy's steel hinged top is a great example of this.

The experiment showed that a Bokashi bin can be a great solution for small composting spaces, reducing the volume of compost by a significant amount.

After adding the chopped up compost material to the Bokashi bin, the contents decreased rapidly in size, suggesting it could be a good option for those short on space.

The Bokashi bin allowed for the collection of compost tea, which was used to water the plants, showing its effectiveness in breaking down organic matter.

The addition of homemade compost accelerator, made with alcohol, sugar, hot water, and urine, sped up the composting process.

A handful of compost from an existing compost heap was added to introduce helpful bacteria, which likely contributed to the rapid decomposition of the organic matter.

The blue toilet roll gathered together in clumps and decomposed slower than the organic material, highlighting the importance of choosing the right materials for composting.

The worms added to the Bokashi bin seemed to thrive, even climbing up the walls of the bin in an attempt to escape the warm compost.

If you're new to composting, start small with a compact bin that can hold about 1-2 cu. ft. of material.

Choose a location for your compost bin that's well-ventilated and accessible, ideally near a water source.

Regularly turning your compost can help speed up the decomposition process, which typically takes 2-3 months in a small bin.

To make the most of your composting experiment, consider taking more care to get the green/brown ratio right. This will help ensure a balanced and thriving compost ecosystem.

One area to explore is the use of compost accelerators. They can significantly impact the speed and efficiency of the composting process, so it's worth investigating their effects.

Compost worms, on the other hand, are a valuable asset to any composting system. They can help remove pathogens like E-Coli and antibiotic-resistant bacteria, making them a crucial component of a healthy compost.

To prevent waste odors, empty your compost bin daily. This simple habit can make a huge difference in keeping your kitchen smelling fresh.

Master composter Devin Reitsma explains that airflow reduces the smell of a compost bin. Tightly sealed lids create anaerobic conditions, which can lead to fermentation.

A breathable lid can help minimize smells. The Minky Homecare food compost caddy and OXO Easy-Clean compost bin have solid plastic lids, which can start stinking up your kitchen by day five.

Charcoal filters can also help contain odors. However, they should be changed or washed every three to six months.

A perforated lid that allows for some oxygen exchange can be very effective. The Epica Countertop Compost Bin and Norpro Stainless Steel Compost Keeper use perforated stainless steel lids lined with thick charcoal filters.

It's worth noting that some bins, like the BioBag Kitchen Counter Food Scrap Bin, take air exchange a bit too far. Its ventilated sides and top are so porous that it's like setting your compost in an open bowl.

A compost thermometer is a handy tool to keep track of the temperature in your compost. This helps ensure that the composting process is happening at the right pace.

For convenience, you can also use smaller compost keepers that fit on your kitchen counter. These allow you to quickly dispose of food waste without having to think about it.

Compost filters are another useful accessory, acting like a garbage bag to keep waste odor-free. They can be easily replaced when the compost keeper is full and ready to be added to the outdoor compost.

Stainless steel is a great choice for kitchen compost bins because it reduces the risk of contamination from acidic food waste. Food waste can leach phthalates out of plastic, so it's best to avoid plastic bins altogether.

Some compost bins, like the Epica, are made entirely of stainless steel, which is a durable and long-lasting material. This is a great option if you want to minimize the risk of contamination.

On the other hand, some compost bins feature stainless steel exteriors with removable plastic liners. These bins are convenient for transporting compost and easy to clean, but the plastic liner can undermine the durability of the stainless steel construction.

Stainless steel bins like the Epica are a good investment if you want high-quality compost.

Garden composters come in a variety of styles to suit every household's needs. You can choose from different types of bins, each with its own unique features.

Enclosed compost bins are the most common type of outdoor composter. They can be made from a heavy-duty garbage can with holes drilled in for aeration, or you can purchase a pre-made composter with an open bottom.

Compost tumblers are the most efficient enclosed composter. They're designed to handle high temperatures and turn to keep microbes active and aerated for faster decomposition.

Vermicomposters, also known as worm bins, use worms to convert food waste into fertilizer. These bins are often multi-tiered, moving worms through the food waste to break it down.

Solar waste digesters break down all food waste, but they're not traditional composters. Instead, they convert the material to liquid, which is easily absorbed by the soil.

Here are the main types of garden composters:

Composting accessories can make a big difference in the ease and efficiency of your composting process.
