Hungry bin. A continuous flow worm farm.


Hi, I’m Ben and I’m the designer and inventor of hungry bin, a continuous flow Worm Compost System Hungry Bin is a very fast and simple way
to produce extremely high quality fertilizer from food and garden waste. The liquid and the castings produced by
hungry bin is quite simply the best The best fertiliser there is. A hungry bin will process up to two
kilograms of food waste per day, but it doesn’t matter if you have less than that, because the worms in the system adapt to match the food supply. Hungry bin
is very simple and easy to use, and I think it looks great too. The reason hungry bin is so efficient is because it creates the ideal environment for compost worms which are the key to fast efficient composting. Unlike other worm farms, hungry bin is a
continuous flow system. You put your food waste in the top, and you harvest high quality nutrients from the bottom. There are no layers or trays to move
around The tapered shape is really important. The taper compresses the castings,
which forces the worms to the surface, because they are surface feeders, not burrowers like earthworms. Just like the soil, the deeper you go, the more compressed it is. The design of hungry bin allows you to
harvest the castings from the bottom as you need it, without disturbing the lifecycle of the worms on the top. That’s the key. By the time the casting makes
it to the bottom of the system, it’s completed and ready to use for your garden. The food waste breaks down at the top of
the bin. It takes about three to four months to make it from the top on the
bin to the bottom. You’ll get about a litre of juice drain out though the hungry bin a week. This liquid is the best fertilizer there is, it contains all the water-soluble
nutrients that your plants need. You’ll get a brick of casting every 2 – 4 months
and because the hungry bin is a continuous flow system there is no heavy lifting to get it out. When you release the floor, only the castings in the bottom of the bin falls out, the rest of it is held up by the taper. Even though this casting is highly
concentrated, it’s PH neutral, so it won’t burn the roots of your plants. In fact, you’ll often find plants germinating in it. You can’t buy fertiliser this good, you’ve got to make it. So why pay for fertilizer when you can make it right by your back door? Hungry Bin. The fastest and easiest way to make the best compost there is.

  1. The Hungry Bin is easy to use, efficient, clean and tidy. What's more my garden is thriving due to the high nutrient food that the Hungry Bin produces. Big thumbs up from me!

  2. I really like the idea of a passive harvest system. I think that adopting a tapered design so that the compost compacts and rests on the side walls saves a lot of labour and allows food to be applied continuously from the top without having to separate the worms, uneaten food, and finished compost. I would probably improve upon your collecting tray with an open bottom with twine strung in parallel lines (twine is flexible so you can stick your hand or a tool through it). The harvesting bucket could sit on the floor or be suspended from the main hopper. The unit does not have to be small either. This can be scaled up ad infinitum by placing units together and removing the side panels to form one large connected trough. 

  3. Ben has to make this affordable ……… Nice and neat but too expensive considering were all making worm farms with old timber and junk in the back yard !

  4. If it can process up to 2 kilogram of waste food per day.  Why does it still take 3 to 4 months to process from top to bottom?

  5. hello ben:  I got my hungry bin a couple of months ago.  I set the bin up as instructed.  I ordered worms and they arrived three weeks after setting up the bin.  We added garden scraps as recommended to the 2 lbs of red wiggler worms.  The first week the worms did well and we could see them then after a while they weren't eating anymore.  They were shaded and feed but seemed to be compelled to crawl out of the bin.  Even as we would open the lid to let light in so the worms would crawl down by morning they would be near the lid looking for a way out.  $40 worth of worms here in the US from Uncle Jim's and I don't see even one in the bin now.  Very sad.

  6. My hungry bin is working fantastically well! great design, the worms are thriving and love not getting disturbed as they do with the stackable systems

  7. So… After reading all these threads and laughing at people who take themselves way too seriously, is the general consensus that this bin is a good or bad purchase? I've just bought one and yet to get it out of the box. I realize I can make some crappy quasi el-cheapo one with my Macgyver knife and a roll of stickytape, but to he honest, I cant be bothered. I'd rather just buy one that works. If this is the real deal please let me know. Preferably from someone who actually HAS one, isn't a self-proclaimed maths whizz , isn't an annelidologist and can respond in a non condescending civil manner (I am aware that is too hard for one particular individual) Thanks in advance!

  8. Hey Dear
    Good After noon.I saw you video on you and became very happy to see this video,Now i decided to get this hungry bin.could you tell me about cost of this in indian currency. my mail id is [email protected],com and my whatsapp no. is +91 7737720388 Could you send me in india ?

  9. the liquid that exits from the bottom of all vermiculture (worm) bins is called leachate. this leachate should not be used for plants that are grown for the purposes of food, however it can be diluted and given to houseplants, decorative shrubs, etc. if you're getting leachate, you are putting too much 'wet' matter into the bin.

  10. is it an issue that the worm wee is left uncovered in the lower part, is it not too smelly? Or can you get a lid?

  11. you present your video with showing Bin from outer side only. so I am confused … how we will be conformed it will prepare compost like your video so easily ?

  12. Sorry way over priced not many people are going to spend between $300-400 for this system. They can buy 3 factory systems for this price which I happen to like very much.

  13. Mine has split around the legs on the frame and when you release the bottom trap door EVERYTHING falls out, not just the castings! So much for taper. TAPER

  14. Hi Ben!, I'm interested in having one Hungry bin for a personal project I have in my neighborhood in Bogotá Colombia, but there are no distributors of the product and I don't have so much money todo import it. Is there any way you can help me?

  15. Same idea but more reasonably priced, https://www.amazon.com/Worm-Inn-Green-Vermicompost-Composting/dp/B00H5EN3RQ/ref=sr_1_fkmr0_1?s=lawn-garden&ie=UTF8&qid=1510441095&sr=8-1-fkmr0&keywords=mega+worm+inn

  16. The water that drips down at the bottom is called leachate. My understanding is that leachate is not always beneficial as a fertilizer due to the potential presence of anaerobic by-products such as alcohol, phenol and terpenes. Is the leachate produced by this product not at risk due to its design?

  17. <£20 tall water-butt, £5 for cheap gravel and weed mesh (to keep separate the worms from the liquid, drained from a tap) <£15 worms (or free if you catch your own, which isn't too hard to be honest) and your garden waste. Can someone help me understand how this piece of plastic is going for over £200?

  18. Come on, considering the cost of material, time to make it (And difficulty to make it that well), effort that is reduced in harvesting, plus high cost of wormcastings, this is not overpriced.  You get what you pay for cheapos.

  19. he said it can process 2 kg of food a day, but takes a few months to get one basket… hmmm
    4.4 pounds of food in daily… does not equate to getting 4.4 pounds of fertilizer… daily. even after 4 months.. the fuck?

  20. I would consider paying $99.00 for it, but that's being generous on my part.  The $399.00 price tag on Amazon, however, is over the top.  Then an additional $46.00 if you want worms with it.  LOL!  I really like the design and function of it, however.  For the time being, I'll stick with the spare plastic bin I found in my garage.

  21. Dear Ben,  That bin is made out of the same materials that my city sanitation bins are made out of, and my city only charges $25 to replace a lost or stolen bin.  The materials are inexpensive, and your product is not difficult to make.  It's a simple design with molded plastic parts.  Nothing difficult about it whatsoever.  I can understand a guy with a unique and useful new product wanting to make a buck on it, but you would do better selling it for modest profit and selling many, many more.  You should take it to Bentonville, Arkansas and pitch it to Wal-Mart.  Then you might really be in a position to make a buck.  Currently you have it very, very overpriced.  You have a potentially huge market in USA and China, and Europe.  Be good to yourself and lower the price to $99.00.  You'll be a millionaire shortly thereafter.

  22. Bought my bin several years ago. Filled it with potting soil then red wigglers then food scraps. Worms have done great, but there is one BIG QUESTION. How do the castings make it into the tray below when they only live in the top 6 inches of the soil? Yes, I can harvest castings from the top, but when I attempt to remove the bottom tray I get the original potting soil AND I stop the removal process because I can tell that the entire contents of the bin will fall out. Plus I could only get it partially reattached due to the weight of the soil pressing down. The liquid in the bottom tray appears to come more from outside moisture rather than anything from the worms. Would love to have you Hungry Bin people respond to the question of how that castings make it into the bottom…

  23. So that worm farm takes up the same floor space as my compost bin and is smaller than my compost bin and cost more and produces less!
    What's the point? my compost bin always has more worms than a worm farm and my worms came free in garden dirt!

  24. I do not get it WHY do you advertise in US , if you do not ship here ?
    PS . was it difficult to put the URL in the description, is this why it is not there ?

  25. Thank you, Tailswag4u. That explanation makes sense with respect to the castings getting to the tray. I'll stick with the effort in hopes for success in removing the tray soon.

  26. Hi Ben,
    I just received my Hungry Bin and I was wondering if you, or anyone, has tried the Bokashi Compost method in the HB, and if so, did it help?
    I have had a worm bin fur several years and I just recently learned about Bokashi Composting, my red wigglers love the stuff, and they break down the compost a lot faster.
    I will be testing the Bokashi Compost our with some worms in my HB.

    Thank you,
    Mike

  27. It’s not hard to make the exact same thing using some plastic and a small curve. No need to spend $400. You can make the taper design using polished smooth wood construction. Then create a plastic barrier within the form with some kind of plastic lining. When it’s all done, you can make a bin for the bottom like he has here. No need to spend $400.

    Another way you can make it is if you use Cob. Cob is dirt with sand and water and straw. Im serious. Dirt. It’s like natural concrete used by ancient civilizations. Good stuff. Used to make fortresses and houses in the old days. Use Cob to make the form. Coat the cob with Lyme plaster finish then polish with olive oil soap. Makes really smooth water proof surface like the plastic device here. All that’s left is to put a bin at the bottom again and then put your potting soil and worms in the top hatch. I’m using this cob method to do it. The only thing I spent money on is a few bags of sand, a small bit of straw, the Lyme plaster a olive oil soap bar. Dirt is free. I have a polishing power tool in my garage. If you are against power tools or don’t have a polishing power tool just use a hard enough smooth river rock. 4 coats of the Lyme plaster before you use the olive oil soap polish step. Works just fine. Final texture for the inside where you use the olive oil soap should be smooth like a Marble counter top. Outside surface isn’t important. Outside surface only gets the 4 Lyme plaster coats. That’s pretty much it. $400 for this Hungry bin? That’s expensive.
