Bear Proof Compost Bin Buyer’s Guide

It’s vital to compare your options before making any buying decision. To help you out, here are some features you need to help you choose the right bear proof compost bin.

Size, Capacity, And Compact Design

Choosing the right size is very crucial in the buying decision. Having a compost bin too big or too small will affect the quality of your compost. The best thing to do is to keep track of how much waste you accumulate every week. 

If you have a lot of waste, the Good Ideas EZC01 would be ideal. But if you need something more compact, try FCMP Outdoor. It’s the smallest among the bins on this list.


Drainage plays a significant role in the composting process. Too much liquid or not enough liquid will also interfere with compost quality. An excellent composting bin should have a system of easy removal of extra moisture. 

Good Ideas CWET-BLK Compost Bin has a bottom tray that collects extra moisture. You can use the liquid solution to pour directly on your soil.

Air Circulation 

If your area is well ventilated, a tumbler with fewer holes and air circulation might work. But you still need to mix the decaying organic materials well. In low ventilated areas, bins with fewer holes or poor aeration will be a problem. VIVOSUN Tumbling Composter has adjustable vents to adapt to the amount of airflow you think your compost needs.

Easy Rotation

Your waste must mix well to get a rich, high-quality finished compost. The effortless rotation is a key for mixing your materials. Good Ideas SMP-BLK is hands-down the best bin to do the job — they don’t call it a soil machine for nothing.

Final Thoughts

VIVOSUN Tumbling Composter is our top pick since it allows for dual composting, it’s easy to use, and it gives you two pairs of gloves.
