Composting is a great way to reduce food waste and create nutrient-rich compost for your garden. One way to do this is by using a sink composter, which separates food scraps and moves them to a bin under your sink for later composting. However, some people may prefer to avoid plastic when composting under the sink. Plastic containers can leach phthalates, or plasticizers, into compost when exposed to acidic food waste. To avoid this, you can use a stainless steel bin, such as the Epica, or a clay pot, which can break down into clay when you're done with it. You can also make your own DIY compost bin using a basic container and drilling holes in the lid for ventilation.

Sink composters: An appliance that separates food scraps, moving them to a bin under your sink
A sink composter is an innovative appliance that allows you to put food scraps down the drain, without the need for a plumber. These devices separate food scraps, moving solids into a bin under your sink, and sending liquids down the drain. This is a simple and efficient way to reduce food waste and create nutrient-rich compost for your garden.
The process is made possible through a precision auger that separates solids from liquids. The auger rotates, pushing solids into the collection bin, with a separation accuracy of 99.9%only liquids are sent down the drain, and the appliance can be used safely on septic fields without damaging the system. Sink composters are also often equipped with carbon filters to prevent odours from escaping into your kitchen.
The convenience of a sink composter is a huge benefit. It allows homeowners to dispose of food waste at the source, saving time and effort. It is also cost-effective, providing an alternative to purchasing fertilizer or other soil amendments. Additionally, it reduces your carbon footprint by diverting waste from landfills, which in turn improves the air quality in your community.
There are a few things to consider when looking to purchase a sink composter. Firstly, ensure that the appliance fits comfortably under your sink, with enough capacity to hold several days' worth of food scraps. Secondly, consider a composter with a removable lid, which makes it easier to clean and empty. Finally, some composters come with additional features such as carbon or charcoal filters to control odours, and it is worth noting that stainless steel options are often more durable than plastic.

Composting without plastic: Use clay pots, buckets, old jars, or wooden crates
Composting is a great way to create healthy soil and support the planet. Here are some ways to compost without using plastic:
Clay Pots
Clay pots are a popular composting method in India, where urban dwellers compost in small spaces. Clay is breathable, creating airflow to keep compost dry and fresh-smelling. You can make your own stackable compost bin by drilling holes in clay pots. Soaking the pot in water and using a towel to stabilise it can help prevent cracks and breaks. Use a small drill bit to create air holes in the side of the pot, repeating the pattern until you have a good amount of airflow.
Buckets
Using buckets is a simple and affordable way to compost. You can use a two-stage system, with sealed buckets to contain kitchen scraps and prevent attracting unwanted visitors like raccoons and skunks. Drill a few dozen holes into 5-gallon buckets with lids for the first stage of "hot composting". The heat generated from decomposition speeds up the breakdown rate. Once the buckets are full, transfer the partially decomposed scraps to an outdoor compost pile or bin.
Old Jars
You can compost in old jars, but they need to be a decent size. For vermicomposting (using worms), a minimum of 5-10L is recommended. Make sure to include air holes, but actively avoid drainage holes. You can freeze your compostables to avoid bugs and take them to a local garden when you have a full jar.
Wooden Crates
You can purchase or build a wooden compost crate. Some prefer to use a kit to build a three-sided bin, using stakes or rebar to keep the sides from pushing out. This allows for a shorter pile that is easier to turn. You can also create a compost bin that can be dismantled by using hinges on the outside corners. When you want to open or dismantle it, simply drive out the pins.

DIY compost bins: Turn a basic container into a countertop composter with proper ventilation
Composting is a great way to reduce food waste and create nutrient-rich compost for your garden. If you're looking to turn a basic container into a countertop composter with proper ventilation, here are some tips to get you started:
First, choose the right container. You can use a variety of containers for composting, such as mixing bowls, takeout containers, old jars, buckets, or repurposed bags. If you're looking for something more stylish or space-saving, stainless steel compost bins like the Typhoon Compost Caddy or the Epica are excellent options. These bins are durable, sleek, and reduce the risk of contamination from plastic. They also come with charcoal filters that help reduce odours. Alternatively, you can opt for a clay pot, which is plastic-free and can break down into clay when you're done using it.
Once you've chosen your container, ensure it has proper ventilation by drilling holes in the lid. For effective composting, your bin requires adequate airflow. Drill about five holes in the lid, evenly spaced apart, to allow for ample airflow. This will help break down the compost and prevent odours caused by a lack of ventilation.
To keep pests away, create a screen for your bin. Measure and cut a piece of nylon screen to cover the holes in the lid. Attach the screen to the underside of the lid using hot glue. This will allow for airflow while keeping fruit flies and other pests out.
Before adding your kitchen scraps, prepare your container by adding a layer of garden soil and shredded newspaper at the bottom. This will help absorb moisture and contribute to the composting process. Then, add your kitchen scraps such as banana peels, coffee grounds, eggshells, and tea bags.
It's important to maintain a balanced ratio of wet and dry food scraps to avoid odours that could attract pests. Stir the compost regularly and add extra newspaper scraps to absorb excess moisture and balance the wet-to-dry compost ratio.
By following these steps, you can easily turn a basic container into a functional and well-ventilated countertop composter.

Avoiding smells: Stir compost, balance wet-dry food scraps, and empty frequently
Composting under your sink without plastic is a convenient way to reduce food waste and create nutrient-rich compost for your garden. However, it can be challenging to keep odours at bay. Here are some tips to avoid smells when composting under your sink:
Stir Compost
Stirring or turning the compost regularly is essential to prevent it from becoming compacted, which can lead to a lack of oxygen and subsequent putrid odours. Turning the compost helps to introduce air, promoting proper decomposition and reducing unpleasant smells. If your compost appears slimy, it is likely too wet, and you should add dry, brown materials such as leaves, newspaper, straw, or sawdust to absorb moisture and restore balance. These brown materials can also help cover food scraps, deterring pests.
Balance Wet and Dry Food Scraps
Maintaining a proper balance of green (wet) and brown (dry) food scraps is critical to avoiding smells. Green materials include fruit and vegetable scraps, eggshells, and coffee grounds, while brown materials consist of dry leaves, grass, and untreated paper. If your compost has too much green material, it can smell like sewage or ammonia. Adding more brown material helps restore balance and reduce odours. Conversely, if your compost is too dry, you should add more green material.
Empty Frequently
Frequently emptying your compost bin is crucial to preventing smells. The more often you empty the bin, the less likely it is to develop an odour. Consider using a smaller bin that encourages more frequent emptying, or store your food scraps in the fridge or freezer until you have a larger amount to compost. Additionally, washing your compost bin after emptying it can help eliminate odour-causing bacteria that may have built up over time.
By following these practices and maintaining a balanced and well-aerated compost mixture, you can effectively avoid unpleasant smells when composting under your sink without resorting to plastic bins.

Composting with worms: Use a worm layer and a separate plastic container to gather scraps
Worm composting is an effective way to reduce food waste and create nutrient-rich compost for your garden. Here is a step-by-step guide to composting with worms using a worm layer and a separate container to gather scraps:
Step 1: Choose a Worm Bin
Select a suitable worm bin for your composting needs. You can purchase a ready-made worm bin or build your own. Worm bins typically have a depth of 8 to 12 inches and a volume of 1 cubic foot of space for each pound of kitchen waste. If you opt for a wooden bin, line the bottom with plastic, such as a plastic bag or an old shower curtain, to prevent moisture from seeping out. Ensure the bin has ventilation holes and a loose-fitting lid to allow airflow.
Step 2: Set Up the Worm Bin
Prepare the worm bin by drilling holes in the sides and bottom, leaving the lid intact. The holes should be a few inches apart and about one inch in diameter. The bottom bin, which collects excess liquid or "worm tea," does not need a top. The top tub, which houses the worms, should have a lid to prevent the worms from escaping. The top tub should also be flexible enough for drilling.
Step 3: Collect Food Scraps
Use a separate container to collect food scraps such as vegetable and fruit scraps, tea bags (without staples), and coffee grounds. Avoid animal by-products like fat, bone, dairy, meat, and waste, as well as plastic, aluminum foil, and rubber bands. Collect scraps in a container with a removable lid to prevent odours and make transportation easier. You can use containers like mixing bowls, take-out containers, old jars, or buckets.
Step 4: Feed the Worms
Once you have collected enough scraps, it's time to feed the worms. Use a trowel to create a hole in the worm bin and add the food scraps. Cover all the food scraps with dirt and moist paper to prevent attracting fruit flies. Only add food to the worm bin once the previous addition has been consumed. Feed the worms once a week in small amounts to avoid overfeeding and potential odours.
Step 5: Harvest the Compost
After 2-3 months, when you notice that the bedding is mostly gone and the bin is filled with compost, it's time to harvest. To prepare, stop adding new food to the bin for about two weeks. Then, use one of the harvesting methods described below to separate the worms from the compost:
- Push all the bin's contents to one side of the bin, removing any large pieces of undecomposed food or newspaper.
- Dump the entire contents of the worm bin onto a sheet of plastic or paper and create several cone-shaped piles. As the piles are exposed to light, the worms will migrate towards the bottom, allowing you to remove layers of compost.
Use the harvested compost in your garden or to make "compost tea" by mixing it with water and allowing it to steep. You can also add worms to your garden bed if you have extra.
By following these steps, you can successfully compost with worms while using a separate container to gather food scraps, minimizing the use of plastic in the process.
