Recycling and Composting

ENVM 649: Principles of Waste Management and Pollution Control

Dr. Robert Beauchamp

benefits of recycling
BENEFITS OF RECYCLING
  • CONSERVES RESOURCES
  • PREVENTS EMISSIONS OF MANY GREENHOUSE GASES & WATER POLLUTANTS.
  • SAVES ENERGY.
  • SUPPLIES RAW MATERIALS TO INDUSTRY.
  • CREATES JOBS.
  • STIMULATES DEVELOPMENT OF GREENER TECHNOLOGIES.
  • REDUCES NEED FOR NEW LANDFILLS & INCINERATORS. .
composting
COMPOSTING
  • BIODEGRADATION:
    • WASTE WATER SLUDGE (BIOSOLIDS)
    • YARD WASTE
  • BULKING MATERIALS: (RETAINS H2O AND ALLOWS AIR CIRCULATION)
    • PLANT RESIDUE
    • MSW REFUSE
    • PAPER
    • SAWDUST
composting cont
COMPOSTING (cont)
  • REQUIREMENTS:
    • MICROORGANISMS-INOCULUM
    • O2 SUPPLY
    • MOISTURE (40%)
    • Ph (NEUTRAL)
    • TEMPERATURE
    • NUTRIENTS
    • SPACE
  • NOTE: SELF GENERATION OF HEAT IF THE MASS OF COMPOST PILE IS HIGH.
uses of compost
USES OF COMPOST
  • EROSION CONTROL
  • EROSION EFFECTS ORGANISMS, WATER RESOURCES, CONSTRUCTION & RECREATION.
  • COMPOST CAN ESTABLISH TURF, REDUCE H2O VELOCITY, & REDUCE EROSION OF SLOPES.
  • PROVIDE PLAYING SURFACES.
  • REPLACE PEAT MOSS.
  • PROVIDES NUTRIENTS & MICROORGANISMS.
  • ENHANCES MOVEMENT OF H2O, AIR, & NUTRIENTS. ?
landscaping
LANDSCAPING
  • COMPOST IS ALTERNATIVE TO TOPSOIL.
  • LANDSCAPE RENOVATION
  • CONTAINER GARDENS.
  • STIMULATES PLANT GROWTH
  • REDUCES PESTS & PLANT INFESTATION.
  • IMPROVES SOIL STRUCTURE.
as compost mulch
AS COMPOST MULCH:
  • STABILIZES SOIL TEMPERATURE
  • CONSERVES WATER
  • CONTROLS WEEDS
  • SLOW RELEASE OF NUTRIENTS
  • PREVENTS SOIL EROSION
  • DARK COLOR ACCENTS COLORS OF FLOWERING PLANTS. 
disease control
DISEASE CONTROL
  • FOR PLANTS AND ANIMALS
  • 10% OF VEGETABLES PLANTED IN U.S. ARE LOST TO ROOT ROT & SOILBORNE PATHOGENS.
  • PROTECTION MECHANISMS:
    • COMPETITION OF NUTRIENTS BY BENEFICIAL MICROORGANISMS.
    • ANTIBIOTIC PRODUCTION BY MICROORGANISMS.
    • SUCCESSFUL PREDATION OF PATHOGENS BY MICRO-ORG.
    • DISEASE-RESISTANT GENES.
tailoring compost
TAILORING COMPOST
  • CAN ENRICH COMPOST WITH DISEASE FIGHTING MICRO-ORG.
  • REPLACES PESTICIDES AND FUNGICIDES.
  • SALT CONTENT OF COMPOSE CAN SUPPRESS DISEASE. TOO MUCH SALT CAN WEAKEN PLANTS.
  • NEED TO TAILOR COMPOST FOR SPECIFIC DISEASES.
mortality composting
MORTALITY COMPOSTING
  • 37 MILLION CHICKENS, DUCKS, & TURKEYS (18-25%) DIE FROM DISEASE.
  • COMPOSTING IS AN OPTION FOR DISPOSAL. PATHOGENS ARE DESTROYED BY HIGH TEMPERATURES IN THE PROCESS.
  • MARKETS EXIST FOR HIGH QUALITY COMPOST. A $250 MILLION PER YEAR PRODUCT.
pest control
PEST CONTROL
  • CAN ERADICATE PARASIDIC NEMATODE (WORM) INFECTIONS
  • NEED A TAILORED COMPOST
  • NUTRIENTS ENCOURAGE GROWTH OF FUNGI & OTHERS, WHICH COMPETE WITH OR DESTROY NEMATODES.
  • CONTRIBUTE TO HEALTH OF PLANTS.
reforestation wetland restoration habitat revitalization
REFORESTATION/WETLAND RESTORATION/HABITAT REVITALIZATION
  • BARREN SOILS RESTORED WITH COMPOST.
  • ADDS HUMUS, NUTRIENTS, & INFRASTRUCTURE FOR PLANTS TO RE-ESTABLISH.
  • CAN ABSORB 4 TIMES ITS WEIGHT IN H2O & CAN REPLACE ORGANIC MATERIALS IN WETLANDS.
  • ASSISTS IN REVEGETATE BARREN HABITATS BY PROVIDING CHEMICAL & MINERAL PROPERTIES OF SOIL.
  • FACILITATES PLANT GROWTH WHICH PROVIDES FOOD FOR ANIMALS.
  • PROJECTS HAVE SHOWN THAT COMPOSE TREATED WETLANDS HAD SUPERIOR GROWTH OVER NON-TREATED WETLANDS..
benefits of composting
BENEFITS OF COMPOSTING
  • KEEPS ORGANICS OUT OF LANDFILLS.
  • PROVIDES NUTRIENTS TO SOIL.
  • INCREASES BENEFICIAL SOIL ORGANISMS.
  • SUPPRESSES PLANT DISEASES.
  • REDUCES NEED FOR PESTICIDES & FERTLIZERS.
  • PROTECTS SOIL FROM EROSION.
  • ASSISTS IN POLLUTION REMEDIATION.
