Session Name: Fundamentals, Hybrids and Safety

Time: Tuesday, January 25, 8:15 AM – 9:45 AM

Presentation Title: Hybrid Approach to Composting

Presentation Description: The presentation covers a design and operational approach for compost facilities that accept food and yard waste.  Technologies to be covered include aerated static pile (ASP) systems; equipment to mix feedstocks; compost turners; dump trucks and conveyors for material handling; and, star and trommel screens.  An ASP system can be combined with open windrow technology to achieve necessary process control, while maintaining cost efficiencies (i.e., hybrid approach).

We will present and discuss the following design and operational items:

Site layout to support hybrid operations.
Use of a compost turner to pre-mix feedstocks.
Use of an ASP system for the initial phase of composting.
Use of a compost turner for subsequent phases of composting and to make soil blends.
Use of star and trommel screen to screen the compost, in process and at finish.
