If the on-the-ground compile pile is the most basic system of composting available, open bin composting is just behind it in terms of simplicity. In fact, you can consider open bins as a tidier variation of the compost pile, easy to access but contained inside some type of bin. If you aren't up for making a DIY open composting bin from wood or wire fencing, there are many interesting bins and bin kits available in commerce.
Open bin composting contains the compost pile, keeping your backyard neater. It's also easier to turn the composting material - a necessary step to hasten the composting process. Usually compost from an open bin is ready to use in between three and 12 months, depending on weather conditions, no matter which bin you select.
1. Compost Bin by GEOBIN
When you consider the weight of wooden fencing and/or heavy metal wire, Geobin's plastic bin is a real innovation. We think this is one of the coolest open bins you can buy. It looks like a roll of plastic fencing material, weighing in at only 7 pounds. The fencing is 3 feet tall and the idea is to form it into a barrel of whatever diameter you desire, then use the clasping mechanisms to attach the ends. The maximum diameter for expansion is 4 feet, but you can start with a narrower bin if you prefer. At maximum expansion, it holds 246 gallons of compost.
- This bin is lightweight and easy to set up.
- It comes with "quick closure keys" that are fast to use, and you won't need any tools to get the GEOBIN compost bin operational.
- It shouldn't take more than 10 minutes if you know where you are going to put it.
- Since the bin is perforated, you get both maximum air ventilation and great drainage, both of which speed up the compost process.
- Upkeep is easy.
- The cost is extremely reasonable at under $40.
- The bin is expandable, but even at maximum expansion it won't hold the amount of detritus a 5 foot square compost pile does.
- Turning the compost can be a challenge if you want to get to the bottom of the pile.
- No open bin on the market will get you into composting cheaper and faster.
