How to Compost at Home
To compost kitchen waste at home, collect vegetable scraps, add dry materials like leaves or paper (browns), maintain a 2:1 ratio of browns to greens, and allow it to decompose over 4–8 weeks with proper airflow and moisture.
What is Composting (Simple Explanation)
Because the Planet Can’t Handle More Waste
Forget the idea that composting is simply dumping food scraps into a pile and hoping for the best. It’s a natural recycling process that transforms kitchen and garden leftovers into dark, crumbly, nutrient-packed soil.
In simpl;e terms:
Composting is nature’s own method of breaking down organic material into healthy soil, using microbes, oxygen, and time. And yes — it works just as well in a flat as it does in a backyard.
Now that you know the gist, here’s the best part: you can make high-quality composting bin right at home without spending a rupee or dollar on overpriced bags from online shops. It’s cheaper, fresher, and better for the planet.

composting basics beginners: How to Start with a Compost Bin
No shopping required. No plastic is promoted. Just reuse what you’ve got and start
The truth?
Your ideal compost bin isn’t in a store — it’s already sitting at home. That old wooden crate, metal pot, or unused container could be your gateway to reducing waste and making free fertiliser.
Whether you're ready to begin composting today or just exploring, the method remains simple, and the best part is that you don’t need to buy anything. You can build your compost bin using what you already have at home.
This guide doesn’t promote plastic use. We encourage you to reuse, repurpose, and reduce. Your compost bin should reflect those values too.
Over time, this turns into nutrient-rich soil because your soil is your plant’s soul, and creating your own soil mix can completely transform plant growth.
Best Composting Methods for Home (Choose Your Style)
Choose the composting style that fits your space, schedule, and lifestyle
(for Flats or Small Spaces)
Indoor Compost Bin
Compact and odour-controlled, great for small homes, flats, or apartments. Fits neatly under the sink or in a kitchen corner, letting you compost food scraps without stepping outside.
Best for people who want convenience and quick access.
Got a yard? Go classic.
Outdoor Compost Bin
Ideal for those with a backyard or garden space. Handles large amounts of garden waste and kitchen scraps, creating nutrient-rich compost in bulk.
Perfect if you want to compost year-round and don’t mind turning the pile occasionally.
(Turn Cooked Food into Compost)
Bokashi Composting
Great for cooked food, meat, and dairy, which standard composting avoids.
Works well for apartment dwellers or anyone who wants to compost meat and dairy without attracting pests.
(Any Space, Any Size)
DIY Compost Bin
Create your compost bin from materials you already have on hand — such as wooden crates, metal containers, or other repurposed items (excluding plastic). Cost-effective, eco-friendly, and personalised to your space.
Great for building a composting habit without buying new equipment.
Vermicomposting
Worm Composting
Uses red wigglers (composting worms) to break down food waste quickly into nutrient-rich worm castings. Works indoors or outdoors and produces some of the most potent natural fertilizer for plants.
Perfect for gardeners and balcony growers.
The goal is to repurpose what you have the bin can be small or large, fancy or rough. What matters is the habit, not the hardware.
composting without smell
Composting in Apartments Without Smell”
One of the biggest fears about composting at home is this:
“Will it smell?”
Short answer: No—if done correctly, compost should smell earthy, not foul.
If your compost smells bad, it’s not because composting doesn’t work—it’s because something is out of balance.
Here’s how to compost in apartments without smell or mess:
Maintain the Right Balance (Most Important Rule)
Always keep more browns (dry waste) than greens (kitchen waste).
Greens: vegetable peels, fruit scraps, coffee grounds
Browns: dry leaves, shredded paper, cardboard
👉 Follow a 2:1 ratio (browns to greens)
This prevents excess moisture—the main cause of bad odor.
Control Moisture (Avoid Wet Compost)
Your compost should feel like a damp sponge — not soggy.
If it’s too wet:
Add dry leaves or paper
Mix the compost to improve airflow
👉 Too much water = smell
👉 Balanced moisture = no smell
Use a Closed but Ventilated Bin
For apartments, choose or create a compost bin that:
Has a lid (to contain odor)
Has small air holes (for airflow)
You can even use:
Old buckets
Clay pots
Repurposed containers
👉 No need to buy expensive bins
Chop Waste into Smaller Pieces
Smaller pieces decompose faster and reduce smell buildup.
Cut fruit peels
Break larger scraps
👉 Faster decomposition = less odor
Avoid Problem Foods (Especially Indoors)
Some items cause strong smells and attract pests:
❌ Meat, fish, dairy
❌ Oily or greasy food
❌ Cooked leftovers (unless using Bokashi method)
Stick to:
✔ Vegetable scraps
✔ Fruit peels
✔ Tea leaves, coffee grounds
Mix Your Compost Weekly
Turning your compost:
Improves airflow
Speeds up decomposition
Prevents bad smell
Even a quick mix once a week makes a big difference.
Keep It in the Right Spot
Place your compost bin:
Under the sink
On a balcony
In a ventilated corner
Avoid completely closed spaces with no airflow.
Quick Reality Check
A healthy compost:
✔ Smells earthy
✔ Doesn’t attract pests
✔ Breaks down naturally
If it smells bad, just adjust:
👉 Add more browns
👉 Reduce moisture
👉 Mix it
That’s it.

What Can You Compost (Greens vs Browns)
The best compost bin isn’t in an online store — it’s in your home, waiting to be repurposed.
Turn everyday items into a zero-cost, planet-friendly compost bin.
Greens (Nitrogen-Rich) | Browns (Carbon-Rich) | Vegetable scraps & fruit peels | Shredded cardboard |
|---|---|
Coffee grounds & paper filters | Dry leaves |
Tea leaves & unbleached tea bags | Newspaper (no glossy) |
Banana peels | Coconut coir or sawdust |
Grass clippings | Straw or hay |
Quick Guide to Using Greens and Browns in Your Compost
Greens are the fresh, moist items like vegetable scraps, fruit peels, coffee grounds, tea leaves, banana peels, and grass clippings. Chop scraps into smaller pieces for faster breakdown, and remember that tea bags should be unbleached and plastic-free.
Coffee filters are fine if they’re unbleached paper.
Browns are the dry, fibrous materials like shredded cardboard, dry leaves, newspaper, coconut coir or sawdust, and straw or hay. Always use plain cardboard and paper without glossy coatings or colored ink, and choose sawdust from untreated wood only. Shred or crumble browns to speed up composting and mix them well with greens to keep your pile airy and odor-free.
For best results, follow the 2 parts browns to 1 part greens rule. Too many greens can make compost wet and smelly, while too many browns can slow the process. Aim for balance, and your compost will reward you with rich, healthy soil.
Earthly Tip:
Chop scraps into smaller pieces and shred browns for faster composting. Keep a 2:1 ratio of browns to greens. It’s your secret to rich, odour-free compost.
Getting this balance right is key. Use our soil mix for plants to find the perfect compost-to-soil ratio for your plants.
Bonus Soil Boosters (Optional)
Once your compost is going, you can give it an extra nutrient kick using common household items you probably already have. These are completely optional, but they can make your compost even richer:
- Crushed eggshells (calcium)
- Epsom salt (magnesium — use sparingly)
- Coffee grounds (attracts worms)
- Banana peels (Potassium)
- Wood ash (pH balancing)

What Not to Compost
Just because something is natural or came from the kitchen doesn’t mean it belongs in your compost bin — especially if you’re composting indoors or in small spaces. These items can cause smells, attract pests, or even harm your compost’s quality.
| Avoid These | Why They’re a Problem |
|---|---|
Meat, fish, or bones |
Rot quickly, smell terrible, and attract rodents or flies. |
Dairy products |
Spoil fast, create strong odours, and cause greasy buildup. |
Greasy or oily foods |
Coat materials and block airflow, slowing decomposition. |
Pet waste |
It can contain harmful bacteria or parasites. |
Glossy paper & magazines |
Plastic coatings and chemical inks can contaminate compost. |
Treated wood or sawdust |
May release toxic chemicals that harm soil life. |
Eco Tip:
If you’re ever unsure whether something belongs in compost,ask yourself: “Will it break down naturally and safely?”. If the answer is no or you’re uncertain, leave it out.

One Habit = Global Impact
You're not just reducing your waste.
You’re joining a movement.
- in India, estimates show that nearly 40% of the food produced is lost or wasted,
- In the U.S. alone, 30–40% of food is wasted every year.
- Households are the #1 source of that waste.
But composting just one bag of scraps per week can save hundreds of pounds of trash annually from hitting landfills.
Imagine if just 10% of working professionals worldwide composted a portion of their scraps.
Final Thoughts: You Don't Need to Be Perfect — Just Start
Look, no one is asking you to churn compost in your suit or collect banana peels like a squirrel.
But maybe you start with a small container under your sink. Or you toss your coffee grounds into a sealed bin instead of the trash.
One step. One change. One habit.
It won’t disrupt your life. It’ll upgrade it.
You’ll feel good. Your plants will thrive. The Earth will thank you.
And before you know it, you won’t just be someone who composts,
