Each year, Miller Compost processes valuable leaf and yard waste, along with food waste from municipal and commercial sources. These organic resources are processed and returned to the communities they come from as a high quality soil amendment that enriches, rehabilitates, and feeds the soil.

“Compost is a natural process through which organic material is converted into a soil-like product or humus. The process works with the help of micro-organisms such as bacteria and fungi combined with air and moisture.” – Compost Council of Canada.
