Setting Up an Under-Sink Composting System in Your UK Kitchen: The Ultimate Handbook
Why Composting is Essential for Your Kitchen
Composting is a simple yet powerful way to reduce your household waste and create a nutrient-rich soil amendment for your garden. By composting your food scraps, you can reduce your kitchen waste by up to 30%, which is a significant step towards a more sustainable lifestyle. Here’s why you should consider setting up a composting system in your UK kitchen:
- Environmental Impact: Composting helps in reducing the amount of organic waste that ends up in landfills, where it produces methane, a potent greenhouse gas. By composting, you are contributing to a greener planet.
- Nutrient-Rich Soil: Compost is a valuable resource for your garden, enriching the soil with essential nutrients that promote healthy plant growth.
- Cost-Effective: Composting saves you money on fertilizers and soil conditioners, making it a cost-effective solution for gardeners.

Key Features to Look For
- Odor Control: Look for bins with airtight lids and replaceable charcoal filters to keep your kitchen odor-free[1].
- Ease of Cleaning: Opt for bins with easy-to-clean designs, such as one-piece molded bins or those with dishwasher-safe components[1].
- Capacity: Choose a bin that is large enough to hold a day’s worth of kitchen waste but not so large that it becomes cumbersome.
- Material: Consider bins made from durable materials like stainless steel or high-quality ABS plastic[1].

Setting Up Your Under-Sink Composting System
Setting up an under-sink composting system involves more than just choosing the right bin. Here’s a step-by-step guide to help you get started:
1. Selecting the Right Location
- Choose a location that is easily accessible but out of the way. Under the sink is ideal because it keeps the bin hidden while still being convenient.
- Ensure the area is well-ventilated to prevent the buildup of odors.
2. Installing the Bin
- If you are using a bin like the Simplehuman Compost Caddy, you can attach it to a magnetic dock on the side of your bin or place it directly on your counter[2].
- For under-sink installation, consider using a pull-out bin system that fits into your cabinet, such as the Simplehuman Dual Compartment Under Counter Pull-Out Bin[4].
3. Using the Bin Effectively
- Add the Right Materials: Include food scraps, kitchen waste, and other organic materials. Avoid adding meat, dairy, and oils as they can attract pests and create odors.
- Maintain the Bin: Regularly clean the bin and replace any filters to keep it odor-free. Use biodegradable liners to make emptying easier.
Understanding the Composting Process
Composting is a natural process that involves breaking down organic matter into a nutrient-rich soil amendment. Here’s a detailed look at the process:

Microorganisms and Their Role
- Composting relies on microorganisms like bacteria and fungi to break down organic waste. These microorganisms thrive in an aerobic environment, meaning they need oxygen to function effectively.
- Products like the GEME Electric Kitchen Composter use microorganism technology to speed up the composting process, making it odorless and efficient[3].
The Importance of Aeration and Moisture
- Aeration is crucial for maintaining an aerobic environment. Ensure your compost bin allows for airflow, either through a soft-seal lid or by regularly turning the compost.
- Moisture is also essential. The compost should be kept damp but not soggy, as excessive moisture can lead to anaerobic conditions and unpleasant odors.
Alternative Composting Methods: Bokashi and Electric Composters
If you are looking for alternative methods to traditional composting, here are two options worth considering:
Bokashi Composting
- What is Bokashi?: Bokashi is a form of indoor composting that uses microorganisms to ferment organic waste. It is particularly useful for small kitchens or for those who want to compost meat and dairy products.
- How to Use a Bokashi Bin: Add a layer of food scraps to the bin, followed by a layer of bokashi bran. Repeat this process until the bin is full. The fermented liquid can be drained and used as a fertilizer, while the solid compost can be buried in your garden[1].
Electric Composters
- How They Work: Electric composters like the GEME Composter use microorganism technology to break down food waste quickly and efficiently. They simulate a compost pile in a contained environment, ensuring that the process is odorless and quiet[3].
- Benefits: Electric composters are ideal for large families or for those who generate a lot of food waste. They require minimal maintenance and can produce compost in a matter of weeks rather than months.
Practical Tips and Maintenance
Here are some practical tips to keep your composting system running smoothly:
Tips for Effective Composting
- Balance the Carbon and Nitrogen Ratio: Ensure your compost has a balanced mix of carbon-rich materials (like leaves and paper) and nitrogen-rich materials (like food scraps and grass clippings).
- Add Bulking Agents: Include materials like straw or shredded newspaper to improve aeration and absorb excess moisture.
- Monitor Moisture: Keep the compost damp but not soggy. Excessive moisture can lead to anaerobic conditions.
- Turn the Compost: Regularly turn the compost to ensure all materials are broken down evenly.
Common Issues and Solutions
- Odors: If your compost bin starts to smell, check that the lid is secure and ensure the bin is not too wet. Adding a layer of bulking agents or turning the compost can help.
- Pests: Fruit flies or other pests can be a problem. Ensure the bin is sealed properly and consider placing it in the freezer between trips to the compost site[1].
Integrating Your Compost into Your Garden
Once your compost is ready, it’s time to integrate it into your garden. Here’s how you can make the most of your nutrient-rich compost:
Using Compost in Your Garden
- Soil Amendment: Mix compost into your soil to improve its structure and fertility. This is particularly beneficial for plants that require well-draining soil.
- Compost Tea: Make a compost tea by steeping a bucket of compost in water. This liquid fertilizer is rich in microorganisms and can be used to feed your plants.
- Mulch: Use compost as a mulch to retain moisture and suppress weeds.
Setting up an under-sink composting system is a simple and effective way to reduce your kitchen waste and create a valuable resource for your garden. By choosing the right compost bin, understanding the composting process, and maintaining your bin effectively, you can make a significant impact on your waste disposal and contribute to a more sustainable lifestyle.
As Samira Tasneem from GreenCitizen notes, “Composting is not just about reducing waste; it’s about transforming our kitchen scraps into valuable compost that can nourish our plants and enrich our soils.”[1]
So, start your composting journey today and watch your kitchen waste transform into a green gold that will make your garden thrive.
