Composting is a key component of regenerative farming; having an efficient, weather-hardy composter is crucial. The Aerobin 400's double-wall polystyrene-core sides are insulated to allow for four-season compost production. This model also requires no tumbling or turning! Simply drop organic waste in at the top and later retrieve compost through bottom side doors. Patented "lung" or aeration core system promotes efficient degradation of organic matter, processing a capacity equal to about 3–4 110-gallon composters. Includes a 4-gallon reservoir that collects leachate, which you can dilute and use as a compost tea. The Aerobin Composter is BPA-free, constructed from virgin polypropylene and high-density polyethylene. Total capacity: 400 liters (106 gallons). Dimensions: 29" W x 29" L x 47" H.
