Calculating Site Capacity

A critical component in developing a facility is understanding how many tons per year (TPY) will need to be processed. Waste audits and waste composition studies will be key to framing this number. (See the Waste Audit section for more).

The following variables will be helpful in determining a site’s needed capacity:

  • Parcel size and percentage of usable area
  • Composting process technology used – static pile, windrows, ASP, in-vessel, etc
  • Stability and maturity requirements of finished product
  • Space requirements to cure and store finished compost
  • Local Zoning and State Regulations will also impact your site’s footprint and capacity
