Virginia Department of Transportation Roadkill Composting Installation


Construction begins on site, with ACT designed bins being set onto concrete working pad


ACT bins placed and Forced-Air supply system being installed


Each bin is plumbed for aeration and leachate collection


Drains inside the bins collect the excess leachate


Connected to an underground leachate collection system where all the leachate is captured, treated, and returned to the bins to be added manually for optimum moisture levels


Built with water tight doors to eliminate leachate leakage


A 1,000 gallon septic tank was installed to hold and treat the leachate. A 30� curb wall and roof were added for easy access.


Clean-outs installed under the concrete pad facilitate easy drainage maintenance


Aeration is delivered via stainless steel tubing on the bin floor


Very small aeration holes provide pressurized air


Aeration is provided by a central blower


Simple, forced-air control panel


Construction now complete, with covers for rainwater protection and walkways for access and daily operation


Fresh roadkill was delivered to site and dumped onto sawdust ready for processing


ACT composting bins loaded with a skid-steer loader; with minimal cover between layers


Each animal covered with a mix of sawdust and poultry litter until a bed was formed for the next animals


Multiple layers were stacked near the rear, forming a 5 foot tall terrace


Bin design allows for standard skid-steer road equipment to move carcasses


Each animal was loaded and covered with mix


Adding leachate to the pile produced pathogen killing temperature performance

Monday’s Temperature 162 degrees


Amazing performance! Only 38 days after loading nearly 10,000 lbs of deer, this material is still 150 to 160 degrees and significantly decomposed


Bin is fully composted, and ready to be moved out. Folks, you are looking where the deer were just 38 days before!


Clean, odor-free compost, 38 days after loading, this material is still 145 to 150 degrees, complete pathogen-kill, last stage decomposition


Major Success!    All  criteria  met!     Proven Composting

"The more  I  learned  about  ACT,  the  more  I  saw   their  concept  fitting  our  way  of  doing  business.   We  needed  to  handle  large  volumes  of  road-­‐kill   during  rut,  and  higher  composting  temperatures   with  no  turning  required  to  provide  aeration;  with   no  moving  parts  to  breakdown,  and  a  clean,   closed-­‐loop  leachate  control  system.  After  one   visit  to  a  NC  farm,  watching  them  load  sows  one   on  top  of  the  other,  I  was  convinced  it  would  work   for  us.  Odor  control  was  extremely  critical,  and   everyone  notices  the  lack  of  offensive  odors.  We've   looked  at  other  systems  but  for  us,  ACT's  forced   air  technology  is  by  far  the  most  applicable  to   handling  our  road-­‐kill  problems.  Now  we  can   focus  on  the  implementation  and  logistics,   because  we  know  their  system  will  handle   whatever  we  throw  at  it.”

Some installations take on a different design based on customer need


Another site example, 3-bin w/ covered work area


Tell me  more….     We    would  sure  like  to  hear  from  you   to  better  understand  your  waste   management  challenges  and  discuss   even  more  ways    the  Advanced   Composting  Technology  systems   could  provide  even  more  benefits  for   your  specific  application.   Be  sure  to  send  us  a  message  from  any   of  the  action  links  at  our  website,  or   just  give  us  a  call  at    828-­‐665-­‐8600
