ECS Solution:

Fisher Road Recycling worked with ECS and quickly determined that using In-Building ASP for both primary and secondary composting would be both a better and less expensive process option. ECS designed a high aeration rate primary process that includes six (6) bunker-wall zones where PFRP and stabilization is achieved. The compost is then moved to secondary composting via front end-loaders to sixteen (16) secondary zones in a mass-bed configuration. Primary and secondary aeration is positive, both using ECS Low Friction Trench aeration floors and processed inside of a fabric covered building. Negative ventilation fans remove building air and run it through an ECS designed biofilter.

Client Needs:

The Fisher Road Recycling facility is a compact site with neighbors close on its property boundaries. The existing compost facility uses an older European made In-Vessel system for primary composting, followed by an ASP inside of a building for secondary composting. Curing is done outside in a separate ASP. In order for the facility to expand the permits required all primary and secondary composting be processed inside of a building, either In-Vessel or In-Building as before.
