The electric Red Dragon – a new type of composter


Brian describes how the Red Dragon works.

The Red Dragon has surprised us!

Six months ago, we sceptics reluctantly agreed to test out a plug-in composter from Korea at the Vancouver Compost Demonstration Garden. We’d already had a bad experience with one electric bin and were quite sure that this one would act badly too.

We put in the required mix of sawdust and microbes supplied with the bin, added some water and plugged the attractive machine into the wall. Then periodically we put in food waste brought from home.

Surprisingly, the waste had turned into compost the next time we looked inside. From food waste to black compost in a jiffy, 12-24 hours! There was evaporating moisture, a pleasant odour and the quietly turning metal prongs that every so often mixed the waste. No worms, no carbon/nitrogen ratio; we simply emptied the kitchen scraps bucket, closed the lid and were done.

We watched this process over the winter. Brian, David and John, three others on the ‘Red Dragon Team’, also tested the machine at their homes, adding more food than us and even dog poo. All of us have had ‘surprising’ success.

A soil test from the lab shows a compost that can be used safely in the garden.

how much electricity does it use?

Hi Brianpickett,

It requires 60 kWh per month in electricity consumption.

It is an in-vessel, aerobic composting machine turning food waste into organic fertilizer while eliminating methane production. Environment Protection Agency concludes aerobic composting does not contribute to CO2 emissions, the main contributors to greenhouse gas and global warming.

Is this scalable?

what is the price for this?

The price is $680 +HST. You can buy online through http://www.encorebuildings.com or go to the Green Good showroom at Dunsmuir and Beatty (downtown Vancouver).

It is neat, especially considering how fast the waste can be transformed. Is it worth it though, to buy another device that uses electricity and oil, when traditional composting doesnt require those resources?

Naturemill makes similar machines for between $200 and $400. I like that the finished compost drops to the bottom of the machine, instead of having to be scooped out.

The company’s website is:

It’s also sold at HomeDepot online.
