Hozelock EasyMix 2-in-1 composter

RRP: £134.99

Our rating: 4/5

Hozelock EasyMix 2-in-1 composter BBC Gardeners' World Magazine review

Pros

  • Smart and compact, made from 90% recycleable plastic
  • Takes both food and garden waste
  • Easy to fill and empty
  • Tank to collect/dispense liquid
  • Makes compost quickly if regularly turned

Cons

  • Lots of assembly
  • Heavy to turn when fuller
  • Needs regular attention for fast composting
  • Household would need more than one composter
  • High price

This compost bin is a &#;tumbler&#; type, designed to enable the frequent turning and mixing of waste material, and produces compost much faster than a traditional compost bin due to the high level of aeration. It&#;s smart and well made, from 90% recycled plastic, and its vermin-proof design enables the composting of both food and garden waste. Thanks to its compact size of 60 x 50 x 65cm, it&#;s also easy to site almost anywhere. Both adding and emptying waste is straightforward, as the hatch is large and opens and locks smoothly with a chunky knob. There are also plenty of grip points to rotate the drum with relative ease, although once the tumbler is around two-thirds full, this becomes quite hard to do due to the weight.
One of its best features is that when the compost is ready, you simply roll the drum off the base to a convenient emptying place in the garden. The nutrient-rich liquid that drains during the composting process is also collected in a tank which clips onto a garden hose, allowing this useful plant tonic to be easily dispensed when watering.
However, while this bin is clearly solidly made and the product of a carefully thought-out design, there are drawbacks. The cost is high in comparison to the amount of waste it can process and the subsequent amount of compost produced. Another, is that it needs &#;tending&#; to tumble the waste: not in itself an arduous task, but to produce compost rapidly this does need regular attention, ideally daily. The air vents do allow small flies to enter, and during warm weather, these fly out in clouds when the hatch is first opened, so opening it and standing back for a minute is advisable. Any garden waste such as stems and woody material aren&#;t suitable to use in this compost bin, if the aim is to produce compost in a period of weeks. However, the chief drawback is that this can&#;t be the only composting solution because the waste needs to be left for a period of a month or so without adding fresh material. This therefore necessitate either having two of these composters, or an alternative composting solution. It comes with a three-year warranty.

Lacewing Easy-Load Wooden Compost Bin

RRP: £76.99

Our rating: 4/5

Available from Amazon (£76.99)

Lacewing Easy-Load Wooden Compost Bin

Pros

  • Good size capacity for price
  • Removable front makes it easy to add waste and harvest compost
  • Long warranty

Cons

  • Drill required for assembly
  • No lid or cover
  • Waste composted slower at front and top

The simple construction of this wooden compost bin allows for a whopping 718 litres of volume. It's made from slats to allow air circulation around the compost and the front ones are removable, making filling up the bin much easier and allowing lots of room to get at the compost when it&#;s ready. However, we found that these wide gaps meant that it composts relatively slowly. Made from pressure treated pine, the slats have a smooth, planed finish and are guaranteed against rot for 15 years.

Harrod Horticultural Slot and Slide Wooden Compost Bin

RRP: from £199

Our rating: 4/5

Available from Harrod Horticultural (from £199)

Harrod Horticultural Slot and Slide Wooden Compost Bin

Pros

  • Very sturdy construction
  • Planks slide out for easy filling/access
  • Accessed on any side
  • Extends with additional three-sided modules

Cons

  • Lots of assembly and requires a powered screwdriver
  • Screws for lid rails too short

Producing some of the best and fastest compost on test, this composter is for serious gardeners. It's designed to be modular, so you can add multiple units for extra capacity, and is very sturdy as it's made of sustainably sourced wood with aluminium fittings. The planks slide out smoothly so it's easy to add waste and remove compost. However, the lid isn't included, and this composter needs a lot of assembly with power tools, so if DIY isn't your bag you may want to look elsewhere.

Garantia 400 Litre Thermo-King Composter

RRP: £94.99

Our rating: 3.75/5

Garantia 400 Litre Thermo-King Composter

Pros

  • Insulated and vented sides
  • Two-part hinged lid for easy filling
  • Made from 100% recycled plastic
  • Optional base plate so can be sited on a hard surface

Cons

  • Multiple lugs make assembly and hatch replacing tricky
  • Connectors don't feel very durable

This plastic compost bin has a great 400-litre capacity. On test, its foamed plastic walls and carefully designed ventilation system helped it handle this volume quickly, producing excellent compost. It's made from 100% recycled materials and includes a wide two-part hinged hatch for easy filling. However, it's a little tricky to assemble.

Thermo Compost Bin Komp 420

RRP: £208.88

Our rating: 3.75/5

Available from Amazon (£183.82) and Garden Delights (£167.95)

Thermo Compost Bin Komp 420

Pros

  • Insulated and vented sides
  • Hinged lid, easy to fill
  • Compost accessed on any side
  • 100% recycled plastic

Cons

  • Assembly hard to align single-handed
  • Comparatively high price

With a robust, sectional design and made from thick recycled plastic, this bin is easy to access thanks to a wide hinged lid. Insulated and vented sides help it compost quickly and it's available in a range of sizes, from 250L to 700L (pictured). However, we found that it's fiddly to assemble without help, and it comes at a relatively high price.

Aerobin 200L Composter

RRP: £191.99

Our rating: 3.75/5

Aerobin Composter

Pros

  • Compost food and garden waste
  • Produced compost in reasonable time
  • Finished compost easy to access

Cons

  • Waste needs pre-mixing for high temp
  • Leachate tank hard to access
  • Made from virgin materials

Our tester liked this this high-tech compost bin, which thanks to its internal &#;lung&#; to circulate air and a rigid recycled plastic outer shell produces compost quickly. It's easy to access, but the bin needs a regular supply of ready-mixed waste to maintain temperature, as well as a drainage hose, which isn't supplied. The leachate tank is also tricky to access.

Forest Garden Beehive Composter 250L

RRP: £189.99

Our rating: 3.5/5

SQUIRREL_TEXT_

BBC Gardeners' World Magazine Review Forest Garden Beehive composter 250L

Pros

  • Durable with effective lid
  • FSC wood
  • Long anti-rot warranty
  • Looks good

Cons

  • Lengthy to build
  • Needs a prop to hold up lid
  • Hard to harvest from hatch
  • Slow to make compost

This attractive wooden, beehive-style compost bin makes a stylish feature in the garden. Made from FSC pressure treated softwood it arrives flat packed and took our tester a lengthy two hours to slot together and build. It has a hinged lid and a hatch at the base for accessing the compost, and tools including a drill and screwdriver are needed to attach both of these. The bin holds 250 litres of compost, although this is more like 230 litres when you allow for a gap at the top for air circulation, and it&#;s easy to add material, as long as you&#;re strong enough to lift the lid with one hand. Our tester fashioned their own prop to hold the heavy lid up while they worked and it&#;s a shame that given the price, one isn&#;t included with the bin as it makes a massive difference to ease of use. It&#;s also awkward to harvest compost from the hatch as material needs regularly turning and so you end up turning and using the compost at the top.
The quality of compost was as you would expect with a cold composting system of this size and it took 18 months before we had a good crumbly mix. The bin is well aerated and the secure lid prevents compost getting soggy from the rain. The bin is also open at the bottom so it&#;s ideal for placing directly on the soil but this does mean that rodents can burrow up into the compost. The bin feels very durable once built and it comes with a 15-year anti-rot warranty, which as the wood is in direct contact with the damp ground is reassuring. The build quality and looks of this bin and are its best features but it&#;s not for gardeners who lack strength or don&#;t want to spend time putting it together.

What materials are compost bins made of?

Compost bins come in a variety of shapes and sizes, and are made using different materials:

Plastic compost bins: Ideal for a small space, the plastic sides and lid retain moisture and heat to encourage rapid decomposition, as well as blocking out light to stop weeds from growing. This type of bin should ideally be placed on grass or earth.

Wooden compost bins: Typically 1x1m but the biggest wooden bins can produce hundreds of litres of compost. They're often modular, so you can fit several together and cycle compost throughout the year to ensure a steady supply. Usually open to the elements, you can also increase their efficiency with a wooden lid or plastic cover.

Hot compost bins: Insulated with a close-fitting lid, these are designed to allow decomposition at a much higher temperature and therefore higher speed than other composters (30-90 days, compared to around six months). They also result in a finer compost. Roughly the size of a wheelie bin, they need to stand on a hard surface.

Wormery bins: These work similarly to compost bins, but are slightly different. They're designed for the small-scale composting of kitchen waste, and use tiger worms to break down material instead of decay. These specialised worms mix and break down the compost quickly and produce a nutrient-rich liquid for use as a fertiliser. Compost worms can also be added to larger bins. However, not all waste is suitable for a wormery, so you&#;ll still need a compost bin too. For more info, check out our expert tests of the best wormeries or read our guide on how to set up a wormery.

You can also make your own compost bin using wooden pallets or corrugated iron. Enclosing the sides will retain heat, which speeds up the rotting process &#; the larger the pile, the more heat. The ideal minimum size is 1m x 1m and, if possible, make more than one, so it's easier to turn the compost. For more help, take a look at our advice on how to build a compost bin and our guides to the best multi-tools, best cordless drills and best hammers, should you attempt to build your own.

How to choose the best compost bin

When choosing a compost bin, consider the size of your plot, the design of your garden and the amount of compost you'd like to produce.

Compost bins come in a variety of sizes and capacities. A narrow plastic bin is perfect for a little city garden, but might not work for a bigger space in the country. On the other hand, a 1x1m wooden bin is great for large quantities of compost, but may be overkill if you have a suburban spot.

This means you should also consider how much compost you'd like to make and how quickly. Wooden compost bins can process the most waste, but if you don't want to wait half a year for your first batch, insulated compost bins speed up the process, but offer less compost. Garden design is a crucial consideration, too. You might have a big patch of unused soil that would fit a compost bin, but might not be sunny enough to make it worthwhile. The type of ground you are setting your bin on is also important, as plastic and wooden compost bins will ideally need to be placed on grass or earth while insulated bins can sit on hard ground.

What to put in a compost bin

There is a whole range of kitchen and garden waste materials which can be put into a compost bin. You need a 50:50 split of nitrogen-rich 'green' material like grass cuttings and carbon-rich 'brown' material like dead leaves. This rough ratio of green to brown waste is crucial, because otherwise the waste won't break down.

The rest is up to you. For green material, try green leaves, garden clippings and any vegetable waste, from potato peels to carrot ends and even coffee grounds. For brown material, use waste twigs, leftover newspapers, sawdust or wood shavings. The only exception here is wormeries, which only take small-scale food waste.

How we tested compost bins

The bins were assembled and sited according to instructions, and then tested over a year. They were given the required type of waste and similar bins were given the same mix of waste at the same time. They were assessed throughout the year using the following criteria with equal marks attributed to each:

  • Design & setup. Looked at ease and clarity of instructions, siting restrictions, and how well the design worked and extra features.
  • Ease of use. Assessed the simplicity of adding waste and then removing compost from the bin.
  • Compost quality & speed. Focussed on the speed the waste rotted down (including checking the temperature using a compost thermometer) and the quality of the finished compost.
  • Value for money & eco credentials. Considered the value relative to the above, including warranty and RRP and as well as eco credentials such as type of material and, if plastic, whether virgin or recycled.

The Very Best Compost Bins | The Strategist

&#;Composting is the human version of re-creating what Mother Nature does out in the wild&#;: mixing together organic materials to facilitate healthy decomposition, says Rebecca Louie, founder of the Compostess website and author of Compost City. Those materials are a combination of carbon-based &#;browns&#; (cardboard, paper, sawdust, dried leaves, et cetera), nitrogen-rich &#;greens&#; (food scraps like apple cores or banana peels), water, and air. Over time, bacteria break down the scraps to create compost, a soil additive rich in plant nutrients &#; plus, you end up creating about 50 percent less trash.

I&#;ve been composting in some form for about ten years in two cities, with scraps going everywhere from an industrial plant to feeding for backyard chickens, so I can attest that the easiest approach is to figure out where and how you&#;ll be composting and work back from there. You might be able to use a smaller countertop bin if your municipality has curbside composting; if you&#;ll need to travel to a drop-off site, a higher-capacity container in the freezer buys you time between trips.

What you can compost varies by site as well. In New York City, for example, compost is in a chaotic moment: The Department of Sanitation runs a curbside composting program in Queens and Brooklyn, slated to expand to all boroughs this month, and maintains a couple hundred app-operated &#;smart composting bins&#; elsewhere in the city. There&#;s also a network of independent neighborhood drop-off sites, but many have closed due to the Adams administration cutting the budget for community compost from about $3 million to zero. (Funding has been restored in the budget, but dozens of sites have already closed.) City-run curbside composting is processed at the Newtown Creek facility in Greenpoint and a site in Staten Island, and accepts a wider range of items, like bones, oily food, and BPI-approved compostable plastics. Drop-off compost feeds to a variety of sites (Big Reuse is the main one). Because these sites don&#;t use industrial machinery to break down compost, they have a narrower list of what they accept but also have a lower carbon footprint.

If you&#;re in New York, you can follow the curbside rollout (and request a brown bin) on the Department of Sanitation website, or find your closest drop-off spot on this DSNY map or on this spreadsheet. Even if there isn&#;t a good drop-off option near you, I&#;ve tested options for creating your own compost, start to finish, indoors.

What

we&#;re

looking

for

Material

Compost bins should be low maintenance, and they don&#;t need to be made from expensive or specially engineered materials. Still, there are a few principles to follow: It&#;s useful if your bin is lightweight, durable, easy to thoroughly clean, and doesn&#;t permanently take on the odors of its contents. Stainless steel and heavy-duty plastic work well &#; they&#;re hardy enough to handle getting banged around but lightweight enough to carry a few blocks to a drop-off spot. Avoid materials that seem flimsy or too precious to contain slimy compost or to get a heavier-duty cleaning.

Capacity

&#;The first thing you should consider before you even look at the aesthetic &#; which I know is hard &#; is how much you produce on a given week and how often you&#;re going to drop it off,&#; says Anneliese Zausner-Mannes, co-founder of Nurture BK. A standard countertop compost bin can fit around a gallon of scraps, which represents a good balance of capacity and portability. But we&#;re favoring systems that come in a few sizes, for households that cook often, and also including indoor systems that can process up to five pounds of food a day. Consider how often you&#;ll want to empty a bin &#; whether it&#;s a quick trip to toss your scraps into a backyard compost tumbler or a trek to a drop-off spot &#; and whether you have space to store scraps in the freezer between trips.

Lid style

If you&#;re keeping your compost on the countertop, a good lid will make the difference between a low-maintenance system and a hellscape of funky smells and summertime swarms of fruit flies. A compost-bin lid should actually not be airtight &#; you want scraps to begin decomposing aerobically (with oxygen), not anaerobically, which makes organic matter take longer to break down and releases smelly gasses, like methane. Some countertop bins have holes in the lid to facilitate airflow or carbon filters to reduce odors; at the very least, a bin intended for the countertop should not create an airtight seal. If you freeze your compost, you don&#;t need to worry about aerobic decomposition &#; like everything else in your freezer, your scraps will be too cold to rot &#; but a lid will help prevent veggie-scrap smell from permeating your freezer.

OXO Good Grips Compost Bin

$23

$23

Material: Plastic | Capacity: 0.75 gallons, 1.75 gallons | Lid style: Removable flip-up lid

The OXO compost bin is a great, fits-everyone bin, first recommended to us by Tonne Goodman, sustainability editor at Vogue, who keeps it in her fridge and uses it to tote scraps to New York&#;s Union Square compost center. It checks all our boxes: It comes in two sizes, the larger of which is high-capacity enough for households that cook often, and it has a non-airtight lid. It&#;s made of easy-to-clean plastic that can handle a few dings, and it is lightweight enough to carry to a drop-off site.

Before testing the OXO bin, I considered myself a freezer-only composter and expected to use it mostly to collect scraps before transferring them to the freezer, like an XL version of a food-prep garbage bowl. But in a happy coincidence, the bin arrived around the same time that curbside composting resumed in Queens, making it a lot easier to get rid of my compost. The freezer bin became an overflow container while the OXO bin got filled up and emptied into the brown curbside bin about once a week. The OXO container is sturdy, easy to clean, and keeps week-old compost smells contained.

I also love its little quality-of-life details &#; the hinged lid detaches for easier cleaning, and it opens via a tab on the lip versus a knob on the top, so it&#;s easy to nudge the bin open and toss a scrap in one-handed. (That doesn&#;t sound important until you&#;ve tried to get rid of eggshells with one hand while the other is covered in bread crumbs &#; it&#;s very helpful.) The OXO bin is both easy to carry and can live in the freezer; its rectangular shape even means that it won&#;t waste as much freezer space as a similar-capacity circular bin.

Best stainless-steel compost bin

Epica Stainless Steel Compost Bin

$28

now 30% off

$28

Material: Stainless steel | Capacity: 1.3 gallons | Lid style: Vented lid with charcoal filter

For something slightly more elegant-looking but still sturdy and functional, I recommend this stainless-steel Epica bin. I used it for about three years, and it performed ably on the countertop through some hot and sticky New York summers. (It&#;s still in use at my former apartment and looks great.) Its vented lid allows for airflow, and two layers of charcoal filters block compost smells effectively. (If your compost is getting soupy but the bin isn&#;t full enough to empty yet, another way to remediate smells is to add carbon-rich &#;browns,&#; like shredded cardboard or ripped-up brown paper bags, to the bin.) Although the lid could get grimy, it&#;s easy to remove the charcoal filter and thoroughly clean it out, an essential quality in any compost bin.

Material: Bamboo fiber | Capacity: 1.15 gallons | Lid style: Vented lid with charcoal filter

There are a lot of cute compost bins on the market, and not all of them hold up. Bamboozle is an exception: According to Strategist contributor Ruth Baron, the 1.15-gallon bin is durable, is easy to carry several blocks, all while being a favorite among &#;hot, environmentally conscious New Yorkers.&#; She likes that it&#;s dishwasher-safe and, despite its lightweight bamboo-fiber construction, reports that &#;she&#;s sturdier than she looks.&#;

It also has one of the highest recommendations for a compost bin: top-tier odor blocking. After accidentally leaving a semi-full bin of compost out on her countertop while she was away over the summer, Baron cracked open the bin and smelled &#;an odor that can be described only as all the reasons people don&#;t compost.&#; After replacing the lid, &#;within seconds, it was as if it had never happened.&#;

Best freezer compost bin

Cambro Clear Square Food Storage Containers

From $10

From $10

Material: Polycarbonate plastic | Capacity: 2 gallons | Lid style: Snap-on lid

In the freezer, where vegetable scraps will not be actively decomposing, you don&#;t need to get complicated: Zausner-Mannes uses brown paper bags and leftover plastic containers, for example. My favorite is an eight-quart Cambro polycarbonate container (also one of our favorite food-storage containers), which sits in the back corner of my freezer and is high-capacity enough that I only need to empty it once every few weeks. It&#;s sturdy and heavy duty, which licenses me to mash down compost with whatever blunt implement I can find, which was useful for buying a couple of extra days when my compost drop-off site was a 15-minute walk away.

Before buying the Cambro container, I used a one-gallon Leaktite plastic pail&#; I&#;ve since repurposed it as a general-use cleaning bucket &#; which also worked well, but its round shape made less efficient use of limited freezer real estate.

Best worm composter

Material: Plastic | Capacity: Up to five pounds of scraps | Lid style: Stacking plastic trays, plastic lid

If you have more time and space to devote to composting and want to keep the nutrient-rich end product to nourish your plants, Diane Miessler, permaculture designer and author of Grow Your Soil, recommends the Vermihut five-tray bin. &#;Worm bins require some simple maintenance to keep them thriving and odorless,&#; Miessler says, but the system scales well to the volume of food scraps you&#;re processing. You can add or remove trays as necessary, and at its peak, the VermiHut can process up to five pounds of food scraps per day. Plus, she says, the final product &#; rich compost writhing with red worms &#; &#;brings joy to most gardeners.&#;

The Vermihut bin doesn&#;t come with worms, which you&#;ll have to buy separately. Louie and George Pisegna, deputy director and chief of horticulture at the New York Horticultural Society, recommend stocking up on red wigglers, which you can buy from her preferred supplier, Uncle Jim&#;s Worm Farm. Pisegna suggests ordering them online &#; one thing to note is that most retailers won&#;t ship during very cold parts of the year to avoid freezing the worms.

Best Bokashi composter

SCD Probiotics All Seasons Indoor Composter Kit With Bokashi

now 14% off

From $60

Material: Plastic | Capacity: 5 gallons | Lid style: Tight-sealing lid

Unlike other methods, Bokashi composting works in the absence of oxygen by mixing microorganism-saturated oat bran with food scraps and storing the blend in an airtight container. This specific bin and bran kit comes recommended by both Marisa DeDominicis, co-founder and executive director of Earth Matter NY, and Pisegna. One advantage of Bokashi, Louie says, is that you can add &#;the crazy Frankenstein stuff in the back of your fridge &#; like condiments or oily things &#; that wouldn&#;t go in a normal compost system.&#; The fermented materials are then buried in your garden to further decompose and nourish the soil.

Best brown compostable bags

Heavy-Duty Grocery Bags

From $13 for 250

From $13 for 250

Depending on your compost&#;s final destination, it may be helpful to use a brown paper bag instead of a green one, the latter of which are designed to be processed in industrial waste plants, says Zausner-Mannes, and it &#;will not break down the same way that your food scraps in organics will&#; in a nonindustrial composting site. Instead, she recommends reusing brown paper grocery and takeout bags, which is a &#;mutually beneficial&#; step: Not only are you recycling, but &#;by dropping off your scraps in a brown bag, you&#;re automatically contributing that carbon to what is otherwise probably a heavy nitrogen base.&#;
