Day 1 (Size of the bin & Drilling holes in the bin) -
Holes in your DIY compost bin are important for aerobic decomposition, holes in the compost bin allow the microbes to breathe and perform composting by decomposing your kitchen waste at their optimum temperature. Because the Microbes in the Compost bin perform respiration and they produce heat. Which increases the optimum temperature of the whole bin for the microbes due to which their rate of activity reduces significantly.
So to maintain constant temperature inside the bins we need to make sure that the holes are drilled at a standard distance suitable for your compost bin
"Remember you don't make your Compost bin a model of swiss cheese also!"
Selecting size of the Compost Bin
If you are worried about selecting the size of the Compost bin. You can have a reference of my compost bin which is 40 cm in height and 30 cm in diameter (from the top). You can select a compost bin of around this size, as it is enough if you are doing it for your house. Just see if you can arrange 2 bins of that size
How to make Holes in the Compost Bin?
There are several ways by which you can make holes in your compost bin easily at home.
Drill Machine
It is one of the most standard way to make holes in the compost bin by which you can accurately select the diameter of the holes by simply selecting the thickness of the drill bit
Using Soldering Machine (I used this method)
This is another best method to make holes in your compost bin. Here also you get full control on the diameter of the holes on the compost bin. The one precaution you should always take with this method is to wear a N95 mask. This is because when the heating of the soldering machine melts the plastic it releases the toxic fumes and if you breathe in that toxic fume you can be in great trouble with your respiratory system. Also perform this in open spaces like balcony or roof top so you don’t pollute your indoor air with those toxic fumes.
Candle and Iron nail
This is the cheapest and the most easily available household method. In this method you simply need to heat the iron nail upon the candle flame and make holes by melting the plastic with hot iron nail. However you need an extreme amount of patience with this method as it can take you hours of making holes in your compost bin. But if you have some patience you can get good results out of this too. Also don’t forget to wear N95 mask as this method will also produce toxic fumes
What should be the Scale and Geometry of Holes?
This is something which entirely depends on the height and the diameter of your Compost bin.
Number of holes needed each side of the compost bin
To know how many holes should be on the side, top (lid) and at the base you can use the tools I made which can actually help you get an idea on the number of holes you need on each side of the compost bin.
“You can shift the slider or simply enter the height and the diameter of your compost bin. These values can be estimated but try to be as close as possible for good results”
Size of the Holes for each side of the compost bins
Here is a table to give an idea of how wide the holes can be on each side of the compost bin. Try to keep the holes approximately of this diameter. For better results. However you don’t need to be after your life to achieve the same diameter of the holes!
Feature | Hole Size (Diameter) |
Bottom (Drainage) | 1 cm to 1.5 cm (Wider is better here) |
Sides (Airflow) | 0.5 cm to 0.8 cm (Standard pencil width) |
Lid (Gas Escape) | 0.5 cm |
How to prevent the compost bin from collapsing?
This is where physics and engineering starts to enter in our simple composting. The problem about making holes is that - The holes make the structure unstable due to which plastic of the compost bin can collapse under its own weight. To prevent that we need to use some engineering but don’t worry it is not going to be rocket science.
We actually need to make holes in the zig zag pattern. This pattern of hole design ensures that the weight is divided equally throughout the compost bin and so no risk of collapsing!
Day 2 (Setting up the base layer of the Compost bin) -
The base layer of the Compost bin is the most important layer throughout the Compost bin. As it absorbs the excess water and provides airspaces for the microbes to breath from the base so let’s understand step by step how to make it
What should the Base layer be made up of?
When building your foundation, you have two primary options: dry leaves or egg crate grey cardboard. While both are excellent carbon sources, if you choose egg crates, remember you shred them into small, palm-sized pieces. This increases the surface area for microbes, allowing them to break down the cardboard quickly. By the time your kitchen waste has transformed into rich manure, your cardboard foundation will have automatically turned into the final compost. If you don't shred the egg grey cardboard they may take months to decompose.
Advantage and Disadvantage of using each material as base
This table is for your reference, you can see both upsides and downsides of using each material as your compost bin’s base layer. I personally like the base to be created from the egg crates as they soak in more liquid and provide excellent airflow.
Feature | Egg Crates (Cardboard) | Dry Leaves |
Airflow | Excellent. They are stiff and stay "fluffy," which keeps the bottom holes open. | Medium. They can get crushed and "mat" together when wet, which might block air. |
Moisture Absorption | Moderate. They absorb some water but not as much as paper pulp. | |
Microbe Activity | Slower. Cardboard takes longer for bacteria to eat. | Faster. Leaves usually already have "good" bacteria on them. |
How to make the base layer of the Compost bin?
Making the base layer of the compost bin involves few steps which you need to follow one by one -
(Step 1) Adding browns as a base
As I previously told you you can select any material it can be either the egg crate cardboard or simply the dried leaves. Just ensure that the base layer you make should be at least 8 - 10 cm thick.
(Step 2) Adding old soil or premade Manure to cover
This is an essential step for the base layer, as this is the kick starter for the decomposition process. This is the same as adding curd to the milk to make more curd. Here you add little soil or manure to the compost bin to make more manure. In this step just make sure you cover the browns layer of what ever material you have chosen
(Step 3) Providing Humidity to the Compost bin
If you have a sprayer bottle just spray some water on the base layer in the bin so that the microbes can get activated and the soil becomes slightly wet. Make sure you don’t add a lot of water that the water just start dripping from the bottom holes of the compost bin
Day 3 (Adding Greens for Composting)
This is the most exciting part of the whole process of making a compost bin. On Day 3, you begin the real transformation of kitchen waste to manure. This day 3 will also be going to be your daily routine for the compost bin so make notes of these steps
(Step 1) Preparing Greens for Compost Bin
Before you put anything in the compost bin, always turn them into small pieces. The size of the greens (kitchen waste) can be different for each of them
Example -
Orange Peels / Banana Peels: Chop them into small 1 cm to 2 cm pieces. Large peels take forever to break down.
Eggshells: Crush them into a powder or very small pieces. Using mortar and pestle or you can even use Electric mixer
Tea Leaves: Squeeze out the excess water so they are damp, not dripping
WARNING: Never put cooked oily food into the compost bin

Pro Tip: Collect the Kitchen waste at one place and dump all your greens together at any time in the day, so that you use less space in the compost bin
(Step 2) Spreading Greens (Kitchen waste) in your Compost Bin
When you put the greens into the compost bin, never just throw them right in the center. Always spread them throughout the previously added layer
Pro Tip: Try to keep the waste a little bit away from the very edges of the bucket to keep the bin cleaner for later use
(Step 3) Covering the greens layer with browns 'Sandwich Layer’
Once you have added your greens and have spread them, cover the layer of your kitchen waste (greens) with Browns (dry leaves and egg crate cardboard).
The layer of the browns you add should cover the greens under it so that no fruit flies can have a party in your compost bin!
(Step 4) The Final Step Squishing the compost
Once you are done adding all your kitchen waste and adding browns layer at the top always squish slightly from the top with your hands so that the waste compresses and your compost bin doesn’t fill up to fast
How to do Maintenance of the Compost Bin?
I feel that making the compost bin is quite easy but when it comes to maintenance of the compost bin it starts to get a little tricky and challenging, but don’t worry it is not rocket science.
I have covered all the points where you might need extra help while maintaining your compost bin. So, make note of all the tips shared here so your compost bin doesn't become a rotting ground.
Daily Sandwich Checklist
Daily when you go to put your greens into the compost bin, always go through this checklist.
Green Check: Are the scraps chopped small?
Brown Check: Did I cover the food completely with browns
By covering greens with browns, you are following one of the most important smell-free composting tips: preventing foul odors and fruit flies from crashing your composting party!
The Moisture Test of Compost Bin
Humidity in the compost bin can accelerate the decomposition (microbial activity) by 10x, but to track moisture in the bin you need a good sense of understanding of how humid the compost bin should be. Here are some signs by which you can understand how to provide humidity and when to not.
If you live in the tropical or subtropical region you have the bonus advantage for your compost bin!
However due to climate change the heat is becoming more scorching in the summer season especially. So lets see how to control humidity
How to check humidity? Every 3–4 days, look at the compost bin. It should look and feel like a wrung-out sponge.
For instance when you take out some compost from the middle of your compost bin and squeeze it, it should only drop 1 to 2 drops. If stream of water comes out it is too wet
What to do if it is too dry? If the cardboard looks like dusty paper, sprinkle a little water.
What to do if it's too wet? If there’s a foul smell or it looks "muddy," add an extra handful of dry, shredded egg crates and stir.
Aeration “The Oxygen Booster”
All organisms need oxygen to survive and so microbes also need it, but don't worry you don’t need oxygen cylinders to provide oxygen to the microbes! All you just need is your hands to mix the top and the bottom layers of the compost bin so the fresh air enters in it
How frequently do you mix? - Give the pile a good stir every 5 to 7 days.
How to mix the compost? - Use a stick to bring the stuff from the bottom/sides to the center.
How to Maintain the Temperature
Many people overlook the importance of maintaining the temperature, that is why their compost bin takes months and even years in some cases to fully decompose! However now you have the secret weapon to overcome this issue which is controlling and maintaining the temperature
Shade is King: Keep the bin in that shady spot you chose. (Never in the direct sunlight as that will cook your compost and kill all microbes
Cooling Down: If the bin feels extremely hot to the touch (more than a warm cup of tea), it might be "cooking" too fast. Give it a light mist of water to cool the microbes down.
Protecting your Roof Top
This is, I think the most important step to protect your house roof top. You must keep a pot under your compost bin, because as the microbes decompose your kitchen waste, they produces a substance called leachate which is a great fertiliser for your plants, but leachate can ruin your roof top by leaving its permanent marks on the floor.
Troubleshooting Table (The Quick Fix)
Problem | Observation | The Fix |
Smell | Smells like rotten eggs or ammonia. | Add Browns. It's too wet. Add shredded cardboard and stir well. |
Flies | Tiny fruit flies hovering around. | Cover better. Add a thicker layer of "Browns" on top. No food should be visible. |
Ants | Ants crawling in or out. | Add Water. Ants love dry compost. Make it slightly more damp. |
No Change | Scraps look exactly the same after a week. | Check Moisture/Soil. It's too dry or needs more manure/soil "starter." |
Conclusion
We are currently facing a global crisis—from water scarcity to toxic soil pollution. At the heart of this is Global Warming, which is accelerating at an exponential rate. But the solution starts in your kitchen itself.
By mastering composting at home, you stop your waste from becoming a 'pollution bomb' in a landfill. Instead of releasing harmful methane into our air and chemicals into our water, you are engineering Black Gold. Proper waste management isn't just a choice; it's our best tool to resist climate change, one bin at a time. Are you ready to join the revolution?

Frequently Asked Questions (FAQ)
Q1: Does composting at home produce a bad smell?
Not if you follow the science! Aerobic decomposition is completely odour-free. If your DIY compost bin smells like ammonia or rotten eggs, it means it is too wet and has turned anaerobic. Simply add more 'Browns' (like shredded egg crates) to restore the carbon-nitrogen balance and eliminate the odour instantly.
Q2: How long does it take for kitchen waste to turn into compost?
With our 3-day scientific setup, the microbial engine starts immediately. In warmer urban climates, like the summer heat in Tropical Region, the temperature accelerates the breakdown process. You can expect rich, dark 'Black Gold' in just 4 to 8 weeks, provided you aerate the pile weekly and maintain optimal moisture.
Q3: How do I keep fruit flies and ants away from my compost bin?
The secret lies in the 'Sandwich Layer'. Always ensure your fresh 'Greens' (kitchen waste) are entirely covered by a thick layer of 'Browns' (dry leaves or cardboard). If ants appear, your pile is too dry—just sprinkle a little water to fix the humidity.
Q4: Can I do composting on a small apartment balcony or rooftop?
Absolutely. A standard 30cm x 40cm bin takes up minimal space and is perfect for urban living. As long as you keep it in a shaded spot to prevent the microbes from overheating in the direct sun, your balcony or rooftop becomes a perfect eco-station.
Q5: What should I absolutely never put in my compost bin?
Stick strictly to raw, plant-based materials. Never add cooked food, oils, dairy, or meat. These items attract pests, cause severe odours, and disrupt the natural microbial activity, completely ruining your aerobic decomposition process. Keep it strictly to fruit peels, vegetable scraps, and garden waste!
