The Double Soft-Close Bottom Mount Compo+ Recycle Center by Rev-A-Shelf allows you to discard food waste with an easy transfer to a large compost bin for future use in gardens, lawns, and flower beds. This eco-friendly waste system is designed for 18" base cabinets and includes a 35 qt. polymer trash can and self-contained compost bin with bio-degradable liners, a no-mess carriage that opens when the lid is raised, and seals when the lid is closed, as well as a carbon filter to eliminate orders and air vents to help speed the compost process. This compost system slides on heavy-duty, brushed aluminum slides that can hold up to 85 lbs. and also includes a fully adjustable 10"H door mount frame ( may require door mount extension brackets, sold separately).
