Bokashi Food Waste Composting Kit 2 × 20L Bins

Cut down on food waste and make something useful from it at home. This Bokashi kit ferments kitchen scraps in sealed bins, creating a pre compost that can be worked into soil, plus a liquid that can be diluted for plants or used to freshen household drains. It is designed for indoor use and suits everyday routines in kitchens, flats and shared spaces.

How Bokashi Indoor Composting Works

Bokashi composting works differently to a traditional compost heap. Food waste is added to an airtight bin and sprinkled with microbe enriched bran. The waste is pressed down with the inner lid to reduce air pockets, then the main lid is clipped shut to keep conditions stable. There is no turning, and when the container is sealed correctly it stays clean and low odour.

What’s Included in This Bokashi Composting Kit

This set includes two 20 litre Bokashi bins with locking lids, two drainage trays, two inner pressing lids, two taps and a full instruction leaflet. The two bin setup lets one container ferment while the other is being filled, so you can keep the process moving without gaps.

Optional Bran Add On

You can choose to include 1kg of microbe enriched bran, ready to use from the start.

What Food Waste Can I Add?

This Bokashi system is suitable for most kitchen scraps, including cooked leftovers, meat and dairy. It offers a practical way to manage food waste indoors all year round, especially when you want an option that does not rely on outdoor space or regular turning.

How to Use the Bokashi Composting Bins

1. Assemble the Bin

Fit the tap into the hole using the washer and nut. Slide the drainage tray inside, add the inner lid, then close the main lid so it seals firmly.

2. Add Food Waste and Bran

Add a layer of food scraps, sprinkle one to two tablespoons of bran, press down with the inner lid to remove trapped air, then close the lid after each use.

3. Drain the Bokashi Liquid

After two to three days, begin draining liquid through the tap every few days. Dilute two teaspoons per litre of water for feeding plants and use within 24 hours. It can also be poured undiluted into drains to help freshen them.

4. Ferment the Full Bin

When the bin is full, seal it and leave it for around two weeks. Use the second bin while the first finishes fermenting.

5. Use the Pre Compost

Dig a hole 20–25cm deep, mix the fermented contents with soil and cover. Leave it for around ten days before planting. You can also add it to a compost heap and mix it with other compost materials.

What Are Effective Microorganisms?

Effective Microorganisms, often shortened to EM, are naturally occurring bacteria and yeasts used to support fermentation. They were developed by Dr Higa and are widely used in Bokashi style food waste systems.

Bokashi vs Traditional Composting

Traditional composting needs oxygen, warmth and regular turning to break material down. Bokashi composting uses fermentation inside a sealed bin, so there is no turning and it can handle foods like meat, dairy and cooked leftovers that are usually avoided in open compost heaps.

Frequently Asked Questions

Can I keep a Bokashi bin indoors?

Yes. When the lid is clipped shut properly, the bin can be kept indoors in a kitchen, utility room or under the sink.

How long does Bokashi composting take?

Once a bin is full, fermentation takes about two weeks. After that, the pre compost needs to be buried or added to an outdoor compost heap to fully break down, usually taking another two to four weeks depending on conditions.

What is Bokashi liquid used for?

The liquid can be diluted at two teaspoons per litre of water and used as a plant feed. Used undiluted, it can be poured into drains to help freshen them.

What should I avoid adding?

Avoid large amounts of liquid, excess oil or grease, plastic, metal, glass, garden waste and anything heavily affected by green or black mould.

Is mould expected during fermentation?

White mould is normal and usually means the process is on track. Green or black mould can indicate too much air or not enough bran, and the contents should be discarded and the bin cleaned.

How often should I drain the liquid?

Drain every two to three days once the bin is in use. Regular draining helps prevent excess moisture slowing fermentation.

Will the Bokashi bin smell?

When sealed correctly, there should be no noticeable smell. Strong odours can mean more bran is needed or the lid was not fully sealed.

Do I need to mix or turn the contents?

No. Press down new waste, add bran and reseal the lid to keep the fermentation conditions consistent.
