AGreen  Mission  •  Combine  organics  with  manure  in  anaerobic  digester  to  

create  energy  and  ferFlizer  •  Help  make  farms  more  economically  sustainable  by  adding  

income  streams  •  Help  food  processors  be  more  sustainable  by  recycling  food  

scraps  for  a  zero-­‐waste  food  chain    •  Compliment  current  composFng  efforts  to  divert  maximum  

amount  of  organics  from  landfills  •  Reduces  Green  House  Gases  (GHG)  by  capturing  methane  

from  manure  and  replacing  “dirty”  electricity    •  Replace  chemical  ferFlizer  used  on  farms  and  grows  more  

feed  for  animals  •  Makes  way  for  greenhouses  using  “waste”  heat,  ferFlizer,  and  

CO2  in  winter  for  more  local  foods.  www.agreenenergyllc.com  ©  April  2012   2  AGreen Energy, LLCAGreen Energy, LLC

Use of liquid fertilizer from Jordan Farm doubled the hay output with no chemicals used – no GHG – doubled the food used to feed the cows to make the milk. A enclosed food chain.

Opportunity  for  dairy  anaerobic  digesters  model  to  contribute  to  U.S.  bio-­‐economy  

Dairy industry can generate value by repurposing food waste from landfills, converting into renewable energy and providing for ecosystem services.

$2.9 Billion

One  out  of  three  food  calories  is  wasted  -­‐  POTENTIAL  

•  29% of America’s food supply lost consumption

•  Estimated total value at retail and consumer levels was $165.6 billion

•  273 pounds of food per person per year

•  Disposal costs add one billion dollars in local taxes annually

•  Coming State bans on organics in landfills – MA set for 2014 to start organics ban

What if 2 tons/wk of food waste were repurposed for fertilizer?

What if 2 tons/wk of food waste were added to manure in a digester?

Remaining  Challenges  

•  LogisFcs  and  infrastructure  of  gathering  and  removing  contaminants  from  organics  from  many  sources,  is  sFll  a  huge  challenge,  parFcularly  with  residenFal  

•  Permikng  pathway  is  cumbersome  –  to  be  helped  by  new  DEP  regulaFons  but  will  need  conFnued  work  as  organics  processing  develops  

•  Finance  barriers  to  developing  anaerobic  digesFon  –  banks  require  10  year  agreements  on  all  feedstocks  

•  Change  –  move  all  of  the  food  industry  to  see  re-­‐purpose  of  organics  as  a  source  of  power;  less  GHG;  and  more  food.
