GREENWASTE COMPOSTINGFACILITY


Transfer station compost facility

TRANSFER STATION/COMPOST FACILITY

  • FACILITY BUILT IN 1994/95

  • GRAND OPENING 6/21/95

  • 4.5 ACRES UNPAVED

  • METHOD OPERATION-OPEN WINDROWS

  • MATERIAL PROCESSED

    • YARD WASTE

    • BRUSH

    • LEAVES, LAWN TRIMMINGS

    • UNPAINTED, UNTREATED WOOD WASTE


Odors

ODORS

  • FIRST ODOR COMPLAINTS SOON AFTER OPENING

  • ODOR MITIGATION EFFORTS

    • USE OF ODOR CONTROL ENZYMES

    • RESEARCHED MASKING AGENTS,FANS,

      EUCALYPTUS TREES

    • EVALUATED PAVING OF COMPOST SITE

    • EVALUATED PURCHASING NEIGHBORING PROPERTIES FOR BUFFER ZONE


All weather operation

ALL WEATHER OPERATION

  • FACILITY PAVED IN 1997

  • OFFER TO PURCHASE NEIGHBORING PROPERTY REJECTED

  • COMPLAINTS CONTINUED


Ag bag composting

AG BAG COMPOSTING

  • STAFF DISCOVERS AG BAG COMPOSTING SYSTEM (1999)

  • INFORMATION REQUESTED FROM AG BAG

  • FIELD VISIT TO NORCAL/VACAVILLE FOOD/YARDWASTE COMPOSTING FACILITY


Compared operating costs

COMPARED OPERATING COSTS

  • WINDROW COMPOSTING

    • HIGHER LABOR COSTS

    • FREQUENT TURNING OF ROWS

    • FREQUENT WATERING IN WARM WEATHER

    • ROWS CAN BECOME SATURATED

    • ODORS CAN BE OFFENSIVE

    • GREATER SPACE REQUIREMENTS

    • RESIDUAL WATER MUST BE TREATED AND COLLECTED

    • MUST REACH 131o F FOR 15 DAYS REQUIRING CONSTANT MONITORING


Compared operating costs1

COMPARED OPERATING COSTS

  • AG BAG COMPOSTING

    • LESS LABOR COSTS (TURNING & WATERING)

    • PATHOGEN REDUCTION PERIOD IS LESS (3 DAYS AT 131o F)

    • ODORS ARE LESS SIGNIFICANT

    • BETTER UTILIZATION OF SPACE

    • BAGGING MACHINE COST $110,000

    • BAGS COST $1300 EACH (USED ONCE)


More research

MORE RESEARCH
