Add More Bins to Your Demeter Composting System

  • Easily expand your composting capacity!
  • Durable powder-coated galvanized steel
  • Front doors and lids open wide for easy access
  • Critter-safe latching lids and doors
  • Wire-grid lids and dividers allow optimal water and air flow

Whether you’re generating so much brown gold, you need to bump up from a Demeter 3 Bin Composter, or you’re working up to a 2-bin system from the Demeter Single Bin Composter, this extension kit lets you expand your system by adding an additional bin.

The clean aesthetic and powder-coated steel construction perfectly combine durability and style. The hinged full-size door and lid open wide to allow easy access for adding scraps, moving and aerating batches, and harvesting nutrient-rich finished compost. The Demeter system’s wire-grid lids and dividers ensure optimal water and air flow, and allow movement of beneficial organisms between bins, creating ideal conditions for your greens and browns to break right down.

Kit includes two additional panels, one additional wire-grid divider, one wire-grid lid, and hardware to connect to your existing Demeter composting bin(s).
