The Aerobin Composter is an investment grade product where sophisticated technology meets the everyday compost pile head on.   Discover how the Aerobin system works, why it can make compost even in colder months of winter, and how it is built to last.

Making compost requires three constants; heat, circulating air, and moisture.  The Aerobin Composter was designed to excel in all three of these categories, even in colder months.  

Heat for Hot Composting:
The center of a fresh compost pile starts out hot as the microbes begin to do their work of breaking things down, but keeping them hot requires mixing or turning, except in the case of the Aerobin.  Hot-Composting means that inside temperatures are enough to kill weed seeds and their roots, and break down plant matter more quickly.  The Aerobin’s sides and lid are double walled and filled with insulation foam to not only retain the heat generated, but to spread heat around the entire pile as well, not just the center.  

Airflow to Eliminate Odors:
Fresh air into the pile helps increase the number of microbes doing the work.  Too little air stops them.  The Aerobin’s patented Internal Lung keeps a constant flow of air back into the pile.  This air flow also kills the other type of microbes that cause unpleasant odors.  Only the good microbes like air, and the result is a sweet, earthy aroma like in the woods.  

Moisture Just Right:
A compost pile must have the right amount of moisture.  Too dry or too wet and the process stops.  The Aerobin moderates moisture build up by allowing any excess to drain into a storage compartment at the bottom of the bin.  The remaining moisture stays with the organic matter allowing maximum efficiency.   Additionally, the moisture collected below is very rich in nutrients and is often called ‘compost tea’.  It is stored for you and can be drained off with the valve provided and used to fertilize household plants and garden vegetables.   

Benefits of Composting:
The benefits are two fold.  Compost greatly improves your soil structure to retain more moisture, which means less watering, and the organic gains make your vegetables taste like they should.   Environmentally, a household can easily reduce up to 50% of its plant matter yard & kitchen waste which is now clogging our land fill sites and giving off greenhouse gases.
