Slide 1

Reusing and Composting ENVM 649: Principles of Waste Management and Pollution Control Dr. Robert Beauchamp

Slide 2

BENEFITS OF RECYCLING CONSERVES RESOURCES PREVENTS EMISSIONS OF MANY GREENHOUSE Gasses & WATER POLLUTANTS. Spares ENERGY. SUPPLIES RAW MATERIALS TO INDUSTRY. Makes JOBS. Invigorates DEVELOPMENT OF GREENER TECHNOLOGIES. Decreases NEED FOR NEW LANDFILLS & INCINERATORS. .

Slide 3

COMPOSTING BIODEGRADATION: WASTE WATER SLUDGE (BIOSOLIDS) YARD WASTE BULKING MATERIALS: (RETAINS H 2 O AND ALLOWS AIR CIRCULATION) PLANT RESIDUE MSW REFUSE PAPER SAWDUST

Slide 4

COMPOSTING (cont) REQUIREMENTS: MICROORGANISMS-INOCULUM O 2 SUPPLY MOISTURE (40%) Ph (NEUTRAL) TEMPERATURE NUTRIENTS SPACE NOTE: SELF GENERATION OF HEAT IF THE MASS OF COMPOST PILE IS HIGH.

Slide 5

USES OF COMPOST EROSION CONTROL EROSION EFFECTS ORGANISMS, WATER RESOURCES, CONSTRUCTION & RECREATION. Fertilizer CAN ESTABLISH TURF, REDUCE H 2 O VELOCITY, & REDUCE EROSION OF SLOPES. Give PLAYING SURFACES. Supplant PEAT MOSS. Gives NUTRIENTS & MICROORGANISMS. Improves MOVEMENT OF H 2 O, AIR, & NUTRIENTS. ?

Slide 6

LANDSCAPING COMPOST IS ALTERNATIVE TO TOPSOIL. Scene RENOVATION CONTAINER GARDENS. Animates PLANT GROWTH REDUCES PESTS & PLANT INFESTATION. Enhances SOIL STRUCTURE.

Slide 7

AS COMPOST MULCH: STABILIZES SOIL TEMPERATURE CONSERVES WATER CONTROLS WEEDS SLOW RELEASE OF NUTRIENTS PREVENTS SOIL EROSION DARK COLOR ACCENTS COLORS OF FLOWERING PLANTS. 

Slide 8

DISEASE CONTROL FOR PLANTS AND ANIMALS 10% OF VEGETABLES PLANTED IN U.S. ARE LOST TO ROOT ROT & SOILBORNE PATHOGENS. Assurance MECHANISMS: COMPETITION OF NUTRIENTS BY BENEFICIAL MICROORGANISMS. Anti-microbial PRODUCTION BY MICROORGANISMS. Effective PREDATION OF PATHOGENS BY MICRO-ORG. Malady RESISTANT GENES.

Slide 9

TAILORING COMPOST CAN ENRICH COMPOST WITH DISEASE FIGHTING MICRO-ORG. REPLACES PESTICIDES AND FUNGICIDES. SALT CONTENT OF COMPOSE CAN SUPPRESS DISEASE. An excess of SALT CAN WEAKEN PLANTS. NEED TO TAILOR COMPOST FOR SPECIFIC DISEASES.

Slide 10

MORTALITY COMPOSTING 37 MILLION CHICKENS, DUCKS, & TURKEYS (18-25%) DIE FROM DISEASE. Fertilizing the soil 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.

Slide 11

PEST CONTROL CAN ERADICATE PARASIDIC NEMATODE (WORM) INFECTIONS NEED A TAILORED COMPOST NUTRIENTS ENCOURAGE GROWTH OF FUNGI & OTHERS, WHICH COMPETE WITH OR DESTROY NEMATODES. Add TO HEALTH OF PLANTS.

Slide 12

REFORESTATION/WETLAND RESTORATION/HABITAT REVITALIZATION BARREN SOILS RESTORED WITH COMPOST. Includes HUMUS, NUTRIENTS, & INFRASTRUCTURE FOR PLANTS TO RE-ESTABLISH. CAN ABSORB 4 TIMES ITS WEIGHT IN H 2 O & CAN REPLACE ORGANIC MATERIALS IN WETLANDS. Helps with REVEGETATE BARREN HABITATS BY PROVIDING CHEMICAL & MINERAL PROPERTIES OF SOIL. Encourages PLANT GROWTH WHICH PROVIDES FOOD FOR ANIMALS. Ventures HAVE SHOWN THAT COMPOSE TREATED WETLANDS HAD SUPERIOR GROWTH OVER NON-TREATED WETLANDS..

Slide 13

BENEFITS OF COMPOSTING KEEPS ORGANICS OUT OF LANDFILLS. Gives NUTRIENTS TO SOIL. Increments BENEFICIAL SOIL ORGANISMS. Smothers PLANT DISEASES. Diminishes NEED FOR PESTICIDES & FERTLIZERS. Shields SOIL FROM EROSION. Helps with POLLUTION REMEDIATION.
