This 220 gal / 1000 L expandable outdoor compost bin handles an entire acre's fall leaf drop in one container—ends the 20-bag rake-and-haul routine suburban oak and maple yards face every October. Expandable roll-up design holds a rigid cylinder during active composting, then rolls to a 35 in x 3.97 in / 90 x 10 cm tube for off-season storage—tucks into a shed corner vs. rigid 220 gal bins that eat winter garage space. HDPE is corrosion-proof, heat-resistant, and outlasts budget PP composters in UV sun and winter freeze-thaw—no brittle crack-lines at year two. Dense perimeter vent holes speed decomposition of leaves, grass clippings, shredded cardboard, coffee grounds, and kitchen fruit/vegetable scraps into finished soil amendment. Fully disassembles, rolls up, and reuses for multiple seasons or relocates to new garden zones. 5-minute no-tool setup. Note: the expandable wall is lightweight—secure with stakes in windy yards.
