Indoor Composting in the Philippines: Your Easy Guide
Hey there! Ever look at your food scraps and wish they could turn into something useful for your plants instead of just ending up in the trash? You’re not alone. Many of us in the Philippines want to compost, but think it’s too messy or complicated for our homes. The good news is, it doesn’t have to be! We can transform kitchen waste into nutrient-rich compost right inside our homes. This guide will walk you through everything you need to know to start indoor composting. So, let’s get those scraps working for us!
Why Compost Indoors in the Philippines?
Diverting food waste from landfills is a big win for the environment. In the Philippines, our landfills are getting full, and food scraps make up a huge chunk of what we throw away. When food rots in a landfill without air, it produces methane, a potent greenhouse gas. Composting at home, even indoors, helps reduce this. Plus, you get free, amazing fertilizer for your houseplants or garden! It’s a simple way to go greener and give your plants a super boost.
Here are some key benefits:
- Reduces Waste: Less trash means less burden on our landfills.
- Creates Natural Fertilizer: Your plants will thank you for the nutrient-rich compost.
- Eco-Friendly: Reduces greenhouse gas emissions from landfills.
- Saves Money: No need to buy expensive fertilizers or soil conditioners.
- Connects You with Nature: It’s a rewarding process to watch waste transform.
Understanding Indoor Composting Basics
Indoor composting might sound tricky, but it’s really a way to speed up nature’s recycling process. We provide a controlled environment for beneficial microorganisms (like bacteria and fungi) and tiny critters (like worms, in some methods) to break down organic materials. The key is balancing the “greens” (nitrogen-rich materials) and “browns” (carbon-rich materials), along with moisture and air.
For indoor composting, especially in a tropical climate like the Philippines, we need methods that handle heat and moisture well, and don’t attract pests or smell bad. The most popular and practical methods for apartment dwellers or small homes are:
- Worm Composting (Vermicomposting): Uses special composting worms to break down food scraps.
- Bokashi Composting: An anaerobic (no air) fermentation process using a special bran.
- Electric Composters: Countertop appliances that quickly dry and grind food scraps.
We’ll focus on the first two, as they are more budget-friendly and widely adopted for home use. Let’s dive into them!
Method 1: Worm Composting (Vermicomposting) – A Gardener’s Best Friend
Vermicomposting is a fantastic way to turn your kitchen scraps into nutrient-rich worm castings, which are basically worm poop and are incredibly good for soil. It’s surprisingly tidy and doesn’t smell if done correctly.
What You Need for Vermicomposting
Getting started with worm composting is straightforward. You don’t need a huge space. Here’s a list of what you’ll need:
- A Worm Bin: This can be a commercially bought system or a DIY one. For the Philippines, plastic totes are readily available and work well. Look for opaque ones to keep out light, which worms don’t like.
- Composting Worms: You can’t just use any earthworm! Red wigglers (Eisenia fetida) or African nightcrawlers (Eudrilus eugeniae) are the best for composting. You can often find these from local gardening groups or online sellers.
- Bedding Material: This is what the worms live in. Shredded newspaper, cardboard, coconut coir (bumbong), or dried leaves work great. Make sure any paper or cardboard is free of glossy inks and tape.
- Food Scraps: Your kitchen waste! More on this below.
- A Spray Bottle: For keeping the bedding moist.
- A Scraper or Trowel: For harvesting the compost.
Setting Up Your Worm Bin
Setting up is easier than you think. Let’s get your worm hotel ready!
- Prepare the Bin: If you’re using a plastic tote, drill several small holes (about 1/4 inch or 0.6 cm) on the sides and bottom for drainage and aeration. You’ll also need a lid with some air holes.
- Add Bedding: Moisten your bedding material so it’s like a wrung-out sponge. It should be damp, not soaking wet. Fill the bin about 2/3 full with this moist bedding.
- Introduce the Worms: Gently place your composting worms into the bin on top of the bedding. Let them settle in for a day or two before feeding them.
- Location: Place the bin in a cool, dark spot. Avoid direct sunlight and extreme heat. Under a sink, in a closet, or on a shaded balcony are usually good spots.
What to Feed Your Worms (and What to Avoid)
Worms are picky eaters! They thrive on certain things and can get sick from others. Here’s a general guide:
Good Foods (Greens):
- Fruit and vegetable scraps (peels, cores, rinds, wilted greens)
- Coffee grounds and tea bags (remove staples/plastic)
- Eggshells (crushed)
- Cooked plain pasta or rice (in small amounts)
What to Avoid (These can harm worms or cause bad smells):
- Meat and dairy products
- Oily foods or greasy scraps
- Spicy foods (like chili peppers)
- Citrus in large quantities (lemons, oranges)
- Onions and garlic in large quantities
- Diseased plants
- Pet waste (dog or cat feces)
Important Tip: Chop up larger food scraps. Worms and their microbes can process smaller pieces much faster.
Managing Your Worm Bin
Keeping your worm bin happy just involves a few regular checks:
- Feeding: Start by burying small amounts of food scraps under the bedding. As your worm population grows, you can increase the amount. Only add more food when the previous batch is mostly gone.
- Moisture: Check the moisture level regularly. If it looks dry, mist it with your spray bottle. If it’s too wet, add more dry bedding. A good rule is “damp, not soggy.”
- Aeration: Gently turn the bedding and compost every week or two with a trowel. This helps air circulate and prevents compaction.
- Harvesting: After about 2–3 months, you should have finished compost. You can tell when it looks like dark, crumbly soil and you can no longer recognize the original food scraps. There are several ways to harvest, often involving separating the worms from the finished compost. A common method is the “hand-sorting” or “migration” method, where you stop feeding one side of the bin and put fresh bedding and food on the other, encouraging worms to move over.
Troubleshooting Common Vermicomposting Issues
Even with the best intentions, you might run into a few snags. Don’t worry, these are usually easy to fix!
| Problem | Cause | Solution |
|---|---|---|
| Bad Odor (like rotten eggs or ammonia) | Too much food, not enough air, or too wet. | Stop feeding for a week. Add dry bedding (like shredded cardboard). Gently aerate the bin. Ensure proper drainage. |
| Fruit Flies or Gnats | Exposed food scraps. | Bury food scraps well under the bedding. Use a lid with air holes. You can also place a small dish of apple cider vinegar near the bin to trap them. Some people use a layer of dry leaves or chopped cardboard on top. |
| Worms Trying to Escape | Bin is too wet, too dry, too acidic, lacks oxygen, or has too much food. | Check moisture, add dry bedding if too wet, or mist if too dry. Add crushed eggshells to balance pH. Aerate the bin. Reduce feeding. |
| Worms Not Eating | Temperature too high or too low, or food is too acidic/spicy. | Move the bin to a more suitable temperature (ideally 15-25°C for red wigglers). Ensure you’re feeding them appropriate items. |

Method 2: Bokashi Composting – Fermenting for Fast Results
Bokashi is a Japanese term meaning “fermented organic matter.” It’s a bit different from traditional composting because it uses an anaerobic process, meaning it happens without air. Instead of breaking down waste completely, Bokashi pickles your food scraps using a special inoculant (usually Bokashi bran) that contains beneficial microbes. The end result isn’t finished compost, but a pre-composted material that breaks down much faster when buried in soil or added to a traditional compost pile.
What You Need for Bokashi Composting
This method is perfect for small spaces and can handle a wider range of food scraps than worm bins.
- Bokashi Bin System: This usually consists of two airtight buckets. One has a spigot at the bottom to drain off the liquid (Bokashi tea). The lid must seal tightly.
- Bokashi Bran: This is the special ingredient! It’s typically rice bran or wheat bran inoculated with Effective Microorganisms (EM). You can buy this online or from specialty stores.
- Food Scraps: All your kitchen waste!
- Storage Area: For the full bin while it ferments.
Setting Up Your Bokashi Bin
It’s a simple, layered process:
- Start Layering: Begin with a sprinkle of Bokashi bran at the bottom of the clean bin.
- Add Food Scraps: Add a layer of your food scraps. Chop larger items into smaller pieces.
- Sprinkle Bran: Sprinkle a thin layer of Bokashi bran over the food scraps, ensuring it covers everything. A good rule of thumb is about 1-2 tablespoons of bran per inch of food scraps.
- Press Down: Gently press down the food scraps to remove air pockets. This is crucial for anaerobic fermentation.
- Repeat: Continue layering food scraps and Bokashi bran, pressing down each layer, until the bin is full.
- Seal Tightly: Once full, close the lid tightly.
What to “Bokashi” (and What to Avoid)
Bokashi is very forgiving with food types. You can add almost all kitchen food waste:
Good Foods:
- All fruit and vegetable scraps
- Meat, fish, and bones
- Dairy products (cheese, yogurt)
- Cooked foods
- Coffee grounds and tea bags
- Eggshells
- Small amounts of soiled paper or cardboard
What to Avoid:
- Large bones (break them down if possible)
- Liquids that aren’t food scraps (like excess water)
- Non-food items (plastic, metal, glass)
Managing Your Bokashi Bin
There are two main tasks:
- Drain the Bokashi Tea: Regularly (every 1-2 days) drain the liquid that collects at the bottom using the spigot onto the bucket. This “Bokashi tea” is a potent liquid fertilizer. Dilute it with water (1:100 ratio is a good starting point) before using it on plants. It can also be used to clear drains or clean outdoor patios.
- Fermentation: Once the bin is full, seal it tightly and let it sit in a cool, dark place for about two weeks. During this time, the microbes are fermenting the waste. You should notice a sweet, pickled smell, similar to wine or vinegar.
Using the Fermented Bokashi Material
After the 2-week fermentation, the material won’t look like compost yet. It will be pickled and might have a slightly sour smell. It’s not ready to use directly on plants because it’s still quite acidic. You have a few options:
- Bury it: Dig a hole in a garden bed or a large planter, bury the fermented Bokashi material, and cover it with soil. Wait another 2-3 weeks for it to break down further before planting directly in that spot.
- Add to a Compost Pile: If you have a traditional compost pile, adding the fermented Bokashi material will significantly speed up its decomposition.
- Use the Bokashi Tea: As mentioned, dilute and use as a liquid fertilizer for your plants.

Method 3: Electric Composters – The Quickest (But Priciest) Option
If speed and convenience are your top priorities, and budget is less of a concern, electric composters are worth considering. These countertop appliances use heat and aeration to dry, grind, and significantly reduce the volume of your food scraps in a matter of hours.
How They Work
You simply toss your food scraps into the composter, close the lid, and press a button. The machine dries and grinds the waste, breaking it down into a nutrient-rich, soil amendment. It’s usually odorless and very fast.
Pros and Cons of Electric Composters
| Pros | Cons |
|---|---|
| Extremely fast (hours instead of weeks/months) | High initial cost |
| Odorless operation | Requires electricity to run |
| Handles a wide range of food scraps, including meat and dairy | The end product is more of a dried food “amendment” than true compost, often needing further incorporation into soil. |
| Great for those with very limited space or who can’t manage traditional composting | Takes up counter space |
| Significantly reduces food waste volume | Can be noisy during operation |
Are Electric Composters Worth It in the Philippines?
While they offer amazing convenience, the cost can be a barrier for many. Additionally, ensuring a consistent supply of electricity and finding replacement parts might be considerations. For most households in the Philippines looking for a sustainable and affordable solution, worm composting or Bokashi are usually more practical choices.
Best Practices for Indoor Composting in the Philippines
No matter which method you choose, keeping a few things in mind will make your indoor composting journey smooth and successful, especially in our tropical climate.
- Temperature Control: Our hot weather can be a double-edged sword. Worm bins can overheat, killing the worms. Bokashi can ferment too quickly or develop the wrong microbes if too hot. If your bin is getting too hot, try to keep it in the coolest spot possible, like a tiled floor, or consider adding some frozen water bottles to worm bins temporarily.
- Moisture Management: Humidity is usually high in the Philippines, so your compost might get too wet. More “browns” (like shredded cardboard or dried leaves) can help absorb excess moisture. If it’s too dry, mist it. Aim for the consistency of a well-wrung sponge.
- Odor Control: Bad smells usually mean something is off. For worm bins, it’s often too wet, too much food, or the wrong food. For Bokashi, odors can develop if the bin isn’t sealed properly or if too much liquid isn’t drained. Always burying food and adding a good layer of bran in Bokashi helps prevent this.
- Pest Prevention: Proper bin construction (tight-fitting lids, small holes for worms) and good practices (burying food, not leaving exposed scraps) are key to keeping pests out
