Composting With Kitchen Waste: A Guide To Composting Your Kitchen

With a little effort and patience, you can turn your kitchen scraps into “black gold” that will benefit your plants and the environment. To get started, you’ll need a compost bin or pile, which can be made from various materials such as wood, plastic, or metal.

Then, collect your kitchen waste, such as fruit and vegetable scraps, eggshells, coffee grounds, and non-greasy food scraps. Avoid adding meat, dairy, or oily foods, as these can attract pests and slow composting.

Layer your kitchen waste with other organic materials like leaves, grass clippings, and shredded paper to create a good balance of carbon and nitrogen. Keep your compost moist but not too wet, and turn it regularly to aerate it and speed up the decomposition process.

Composting With Kitchen Waste

What Is Composting?

What Is Composting

This process can occur in nature but can also be done intentionally in a compost bin or pile. The materials that can be added to a compost bin include food scraps, yard waste, and other organic matter. Through decomposition, microbes break down these materials and create rich soil that can be used to fertilize gardens and landscapes.

Types Of Composting Systems

Types Of Composting Systems

Backyard Composting: This is the most accessible and popular form of composting for individual households. It involves creating a compost pile or using a bin in the backyard. Backyard composting allows for decomposing kitchen waste, yard trimmings, and other organic materials.

Vermicomposting: Vermicomposting utilizes earthworms to aid in the decomposition process. A vermicomposting system typically consists of a worm bin, where a specific species of earthworms, such as red wigglers, break down the organic matter. The worms consume the waste, and their castings (worm excrement) create nutrient-rich vermicompost.

Tumbler Composting: Tumbler composters are containers designed with a rotating or tumbling mechanism. These systems provide an efficient way to turn and mix the compost, aiding in decomposition. Tumbler composting offers convenience, faster decomposition, and better odour control than traditional pile composting.

Compost Bins and Enclosures: Compost bins and enclosures come in various sizes and designs. They provide a contained space for composting, aiding in heat retention, moisture control, and aesthetics. Some bins have multiple chambers, allowing for continuous composting, with one chamber being filled while the other matures. Compost bins and enclosures are available in plastic, wood, or metal materials.

Compost Trenches or Pits: Compost trenches involve digging a trench or pit directly into the soil, where organic materials are added and covered with soil. This method allows in-ground decomposition, and the resulting compost gradually enriches the surrounding soil. Compost trenches benefit larger quantities of organic waste and are commonly used in garden beds or agricultural fields.

Aerated Static Pile Systems: Aerated static pile systems are utilized in larger-scale composting operations. These systems create a large, insulated pile of compostable materials, which is aerated by either passive or forced airflow.

What Kinds Of Kitchen Refuse Can Be Composted?

What Kinds Of Kitchen Refuse Can Be Composted

However, not all kitchen refuse can compost. It is important to know the kinds of waste that can be composted to avoid contamination and unpleasant odours. Fruits and vegetables, coffee grounds and filters, eggshells, and tea bags are all excellent candidates for composting. These organic materials provide nitrogen, carbon, and other essential nutrients that support the growth of beneficial microorganisms in the compost.

However, meat, dairy products, oily foods, and cooked food scraps should avoid as they attract pests and emit unpleasant odours. To ensure a successful composting process, it is also important to maintain the right balance of carbon-rich and nitrogen-rich materials, keep the compost moist but not too wet, and turn the compost regularly to aerate it.


  1. Fruit and vegetable scraps: Peelings, cores, seeds, rinds, and any leftover or spoiled pieces from fruits and vegetables.
  2. Coffee grounds and filters: Used coffee grounds and unbleached coffee filters.
  3. Tea bags and leaves: Natural fibre tea bags and loose tea leaves.
  4. Eggshells: Crushed eggshells, which are a valuable source of calcium.
  5. Nutshells: Shells from nuts like walnuts, almonds, or pistachios.
  6. Stale bread or grains: Unused portions of bread, cooked rice, pasta, and other grains.
  7. Paper products: Unbleached paper towels, napkins, parchment paper, shredded uncoated paper.
  8. Yard waste: Grass clippings, leaves, small branches, and plant trimmings.
  9. Shredded newspaper or cardboard: Unbleached and non-glossy shredded newspaper or cardboard.
  10. Dry leaves: Collect dried leaves from your yard or garden.
  11. Wood ash: Small amounts of wood ash from untreated wood (avoid using ash from charcoal or chemically treated wood).
  12. Manure: If available, well-aged animal manure from herbivorous animals (such as cows or horses).

How To Make Compost From Kitchen Waste In Easy Steps

How To Make Compost From Kitchen Waste In Easy Steps

It’s important to follow a few easy steps to compost with kitchen waste.

Step 1: Gather your kitchen waste, such as fruit and vegetable scraps, coffee grounds, and eggshells. Avoid adding meat, dairy, or oily foods, as they can attract pests and slow composting.

Step 2: Find a suitable container for your compost. Using a compost bin with a lid is recommended to keep out animals and maintain moisture levels. You can add dry leaves or shredded newspaper to balance the moisture content.

Step 3: Once you have your container, layer your kitchen waste with the dry materials and mix it all together. Keep the mixture moist by adding water and stirring it at least once a week.

How To Compost Kitchen Waste In Apartments

Choose a composting method: Opt for a small-scale composting method suitable for apartment living. Vermicomposting, which involves using worms to break down organic waste, is ideal. Worm bins are compact, odourless, and can keep indoors.

Select a suitable worm bin: Purchase a worm bin designed for vermicomposting. Alternatively, you can create your worm bin using a sturdy container with proper ventilation.

Set up the worm bin: Place a layer of moistened bedding material at the bottom of the bin. Bedding can shred newspaper, coconut coir, or dried leaves.

Collect kitchen waste: Collect kitchen waste such as fruit and vegetable scraps, coffee grounds, tea bags, eggshells, and shredded paper or cardboard. Chop or blend larger pieces to facilitate decomposition and prevent overwhelming the worms.

Feed the worms: Add small amounts of kitchen waste to the top layer of the worm bin. Bury the scraps under the bedding material to avoid fruit flies and odours. Be mindful not to overfeed the worms, which may lead to issues. Start with small quantities and gradually increase as the worms adjust and consume the waste.

Maintain moisture and temperature: Ensure the bedding remains moist but not waterlogged. Sprinkle water as needed to maintain a damp environment. Keep the worm bin in a location with a stable temperature between 55-77°F (13-25°C), as worms thrive within this range.

Be patient and maintain the worm bin: Allow the worms to work their magic over time. Regularly monitor the worms’ moisture levels, temperature, and overall health. Adjust the feeding schedule accordingly, and occasionally check for undecomposed materials that need removal.

Harvest vermicompost: After a few months, the worms will have transformed the kitchen waste into nutrient-rich vermicompost. Harvest the vermicompost by gently separating the worms from the finished compost.
