  • Simple and easy to use: With a Hungry Bin you never need to touch the worms. There are no heavy trays to move around. The waste going in and the castings coming out are at opposite ends of the system, so you don’t have to deal with one to get to the other. You simply lift the lid with one hand and deposit the worm food in the top and the worms do the rest. You never need to disturb the worms!
  • Highly efficient:The unique shape encourages worms to access the food scraps at the top, leaving compressed castings below – Worms don’t like compression so they stay at the top where the food is. Hungry Bins have a large processing capacity of up to 2kg of organic waste a day. One Hungry Bin can process the food waste of a family of 4-5 people, however they  also work well at lower capacities of only one person households.
  • High quality construction : The bin is manufactured in UV stabilised, food grade plastic on a zinc plated frame, making it more robust than black tray based farms. The Hungry Bin is designed for decades of service, not a short-lived product which will end up becoming waste itself. Designed and manufactured in New Zealand, from high quality virgin food-grade plastic which does not contain heavy metals or BPAs as many recycled plastics do. The product should last 25-35 years under normal use.
  • Easy harvesting: The design allows easy harvesting of castings without heavy, messy lifting – just clip off the lower tray to access 4 litres of compressed castings. When you harvest the castings you rarely need to separate the worms which is a problem with stacker type worm farms where the worms are often crawling all over the place!
  • No clogged taps or smells: Each bin produces quality worm castings and liquid soil conditioner for your garden. The flow-through system with in-tray filter for liquids means no more clogged taps – liquid comes straight through the bottom of the bin into the tray or bucket below. The Hungry Bin does not have a tank which tends to fill up with silt and which allow the worms to drown in.
  • Pest resistant: The tight fitting lid keeps pests out and is at a comfortable operating height –very convenient to open and close. Rats and vermin cannot climb up the smooth metal legs. Possums cannot lift the lid which has an anti-wind clip
  • Robust and mobile: And the Hungry Bin has large diameter wheels, makes moving the bin light work. There are no unstable legs which can fall off.
  • Well written informative manual:The Hungry Bin comes with probably the best written worm farming manual, plus a useful “week by week” calendar which will help you through the first months from set-up. And if in doubt there is the Worm lovers on line resources which will answer any unusual worm farming questions you might need answered!
  • Attractive, clever, sustainable design: The Hungry Bin’s attractive design aesthetic means you can place it in a prominent position, not hidden away like an ugly garbage bin. The bin is designed around the life cycle and behavior of the compost worm, harnessing a fundamental natural process. It promotes “ value ” in food waste, and helps educate and assist in more sustainable practices.
  • High quality output: Because of its deep volume, castings and worm juice harvested from a Hungry Bin are “ finished ”and are less likely to contain unbroken down organics – which create smells and can damage plants. You get a better quality of product from a Hungry Bin. There is nothing better for plants and gardens than the product of a worm farm – the nutrients are in a plant available form and are suitable for all plants. Compost from a worm farm is processed twice as quickly as a regular compost heap and is up to 5 times more effective.
  • Slower to heat up: Due to the larger volume, the core of the Hungry Bin is takes longer to heat up during heat waves so the worms survive longer before emergency action is required.

worms escaping

everything is fine but my worms want to crawl out. I feed them and they still want to get out. I have put small led light and this keeps them in but they should stay in on their own

Vermilovin' it!

I've had the Hungry Bin for the last couple of weeks and the kids and I are loving it. I have not collected vermicompost yet but have collected the leachate and that has brought some life back into plants that have looked under the weather for years.


Hungry Bin

So far, so good! In reading other reviews, I’m not sure if the one I received is a newer model, but I haven’t seen any of the issues others seem to have had. Assembly was super easy! Took maybe 5 minutes. It appears sturdy and if assembled properly I don’t see any issues with the top becoming separated from the bottom while moving as it’s locked in place by hinged fasteners. Also, the bottom casting tray is firmly secured by similar fasteners and I can’t see how it could just “come loose” if it’s attached properly. Make sure you buy at least two of the coir bricks and have a bag of peat moss/garden soil on hand to fill the bin for the first time. Worms are doing great starting with 2000 & following the directions. I have yet to harvest castings as it plainly says not to try that for at least 6-8 weeks or so to allow compaction in the bin. People complaining about the bin emptying from the bottom probably didn’t read the instructions and opened it too early. The process takes time and if you expect castings quickly, just buy some! The worm tea is available in the meantime and the first few loads from the casting tray will be the material you loaded in the bin to start with, not pure castings. It will be enriched however by the worm tea that drains through it until the bin is in full operation. Keep that in mind when first filling the bin so it compacts properly. I loaded it with a mix of garden soil and peat moss first, then the coir bricks. Two bricks + 20 cups of water will fill a 5 gallon bucket. This bin is big so plan on a 25lb bag of garden soil and two 5 gallon buckets of coir or peat moss to fill to 3/4 full allowing room for the food. Directions are excellent if you follow them.

The new guy to vermicomposting

I bought my Hungry Bin in Feb/2022 when I was new to vermicomposting and didn’t know a thing about it. What sold me on the Hungry Bin was the flow-through concept and its clever design with these benefits: no lifting of heavy trays and no sorting out worms from the castings. I have just made the 30 days milestone, My 1st goal was to make sure worms stayed alive & happy. So far everything seems to be on track.
