Recycling and Composting

ENVM 649: Principles of Waste Management and Pollution Control

Dr. Robert Beauchamp


Benefits of recycling l.jpg
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 l.jpg
COMPOSTING

  • BIODEGRADATION:

    • WASTE WATER SLUDGE (BIOSOLIDS)

    • YARD WASTE

  • BULKING MATERIALS: (RETAINS H2O AND ALLOWS AIR CIRCULATION)

    • PLANT RESIDUE

    • MSW REFUSE

    • PAPER

    • SAWDUST


Composting cont l.jpg
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 l.jpg
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 l.jpg
LANDSCAPING

  • COMPOST IS ALTERNATIVE TO TOPSOIL.

  • LANDSCAPE RENOVATION

  • CONTAINER GARDENS.

  • STIMULATES PLANT GROWTH

  • REDUCES PESTS & PLANT INFESTATION.

  • IMPROVES SOIL STRUCTURE.


As compost mulch l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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.
