When I was at the Masters Conference at Garden Organic I was very interested to see a new ( to me) design of wormery. Johannes Paul of Omlet was showing a new addition to their product range - the Hungry Bin. Omlet are selling these wormeries in the UK, they originate from New Zealand and are an interesting design,
According to the makers, Low Impact Ltd
The Hungry Bin is a unique design. It creates an ideal living
environment for compost worms. The worms convert organic waste into worm
castings and a nutrient-rich liquid, which are both high-quality
fertilisers. The liquid drains freely from the bin and into a tray
placed below it.
The tapered shape of the bin compresses the castings, encouraging the
worms to move to the surface layer to access fresh food. Compressed
castings are easier to handle and largely free of worms. It is a simple
process to collect both the castings and liquid produced by the hungry
bin.
I must admit I was very impressed by the design when looking at it on display and when Johannes offered me a Hungry Bin to try out, of course I said yes ( I
never pass up the chance to experience something new involving
composting and worms)
So when the box arrived yesterday, along with two large lidded buckets of worms and bedding, I was really excited (I'm funny like that!) and couldn't wait to get the system set up. Fortunately we had a dry and sunny day yesterday so I was able to take lots of photos as well
Packaged in a cardboard box, what looks like proper sellotape to seal it (therefore compostable!) and the instructions are in a paper bag. Full marks for packaging!
All the parts nested together, like a Russian Doll
Very easy to understand instructions
Compostman stands next to the completed wormery - it took less than 10 mins to build.
In situ, behind the Barn, facing the Polytunnel - so I can feed it easily "little and often". There is a comprehensive "owners manual" to tell you how to
set up the wormery once you have put it together, as well as lots of
advice on the Omlet website.
Adding the bedding for the worms - when you first set it up you need to fill it half full with compost, coir, growing medium, soil or a mixture of all of them, to give the worms something to live in. I used spent home made compost from the potato planters I have just harvested.
As soon as I opened one of the worm buckets Babs was there! She must be able to smell worms at 100 paces!
Worms!

Titch was bored, so went to sleep as there were no more worms on offer.
The
Hungry Bin web site says about the design
The hungry bin is the result of several years of design development
by inventor Ben Bell, of New Zealand. Ben is a keen gardener, composter
and worm farmer. He felt that the existing worm farms on the market
could do with some improvement, and in true Kiwi spirit he decided to do
it himself. The original idea for hungry bin evolved from earlier
models Ben created using broken kerbside rubbish bins.
I must admit it DOES look a bit like a rubbish bin on wheels!
The unique shape of the bin creates a large surface area allowing
all the worms living in the hungry bin to easily access the food scraps
at the top – exploiting the fact they’re surface feeders, and
increasing their processing capacity. The tapered sides also encourage
the worms to stay on the surface, while compressing their castings
below.
I was particularly impressed by the large surface area and when I went out tonight to check on the Hungry Bin the worms were busily working in the material I had added on top of the bedding. A lot were on the inside of the lid, though. That tells me it IS going to rain, later on!
Once the compost process is complete, the hungry bin is designed to
allow the simple and easy harvest of both finished castings and liquid
fertiliser. Harvesting castings does not involve any heavy, messy
lifting. The floor of the bin is easily removed, allowing approximately 4
litres (3/4 gallons) of castings to break away at the bottom of the
taper. This allows the easy removal of finished castings from the bin.
Removing the castings is a relatively clean process. Finished castings
are largely free of worms.
I saw this demonstrated at Ryton - the tray really does come out full of worm casts and the material really did stay put! The only fault I can find so far is the liquid tray is easily accessable to the chickens - who will drink the worm "juice".
The lid is at a comfortable operating height, and convenient to open
and close. Tight fitting, it prevents pests from entering but has
sufficient venting to create healthy airflow. The hungry bin even has
wheels, making moving the bin light work.
I found it easy to put material into the bin, so did both Compostman and Compostgirl.
If you are interested in buying one of these bins, you can order one from the
Omlet Hungry Bin pages
I will write more in a few days, but so far I am very impressed with my Hungry Bin.
