ANALYZING
DATA IN STATE OF GARBAGE IN AMERICA, EPA REPORTS
Nickolas J. Themelis
Researchers
at Columbia University’s Earth Engineering
Center analyze why there are differences between
BioCycle and EPA/Franklin Associates statistics
concerning waste generation and amounts recycled.

SOLID
WASTE COMPOSTING TRENDS IN THE UNITED STATES
Nora Goldstein
Operations
at most of the existing facilities are
steady-state. Aside from two projects in
construction, new growth is coming from
residential source separation pilots in
California, Minnesota and Washington State. p38 |

SORTING,
PROCESSING WOOD AT C&D RECOVERY SITE
A
possible ban on disposing of unprocessed
construction and demolition waste in
Massachusetts has led some companies to install
mechanized sorting systems to maximize recycling.

SUPERMARKET
CHAIN SETS UP FULL-CYCLE COMPOSTING PROGRAM
Jerome Goldstein
Residuals
from a central food processing center are taken
to a nursery where they are mixed with leaves and
windrowed on a three-acre site. Finished compost
will be bagged for sale at stores. p28 |
STORM
BRINGS MASSIVE WOOD WASTE TO NORTH CAROLINA
Rhonda Sherman
City
crews and private contractors use buckets, booms
and pickups to collect tons of materials. One
city alone estimates 500,000 cubic yards of
debris will be collected. p30 |
TRUCKS
WITH AN APPETITE FOR FOOD RESIDUALS Robert
Rynk
Three
composting facilities devise vehicles to capture
food residuals for composting. All generators
serviced set material out in wheeled carts.p32 |

COMPOST
OPERATORS – BIOFILTER DESIGN, CARE AND
FEEDING Robert
Spencer and Charlie Alix
When
composting facility biofilters are properly
designed and operated, they remove more than 90
percent of the odor compounds that pass through.
Critical parameters include retention time of
odorous air in the filter, moisture management, a
good media mix and dust control. p45 |

USERS – APPLYING COMPOST TO SUPPRESS TOMATO
DISEASE William
Cheuk, K. Victor Lo, Dr. Richard Branion, Bud
Fraser, Robert Copeman and Peter Jolliffe
Tests
in British Columbia show significant reductions
in root rot disease and improved crop yields by
addition of compost produced from a mixture of
greenhouse plant waste, spent growing medium and
bark amendment. p50 |

MAKING
ELECTRICITY FROM MANURE
Dan Meyer
Operations
at an Iowa dairy farm use a microturbine and
generator to produce power, provide heat and
reduce manure management costs. p52 |
INPUTS
AND OUTPUTS OF AN ANAEROBIC DIGESTION SYSTEM
On
a dairy farm, an anaerobic digestion and energy
conversion system takes in several inputs like
manure and cool water and delivers useable
outputs including hot water, electricity, treated
liquid and solids for bedding. Diagram shows
where the inputs and outputs are moved and
converted. p52 |
SOLID
WASTE AS FEEDSTOCK FOR BIOGAS RECOVERY Dave
Hogan and Robert Craggs
More
companies, government officials and organics
recyclers are now actively involved in making a
reality of the biomass/energy potential. p56 |

SOIL
REMEDIATION WITH MSW COMPOST
Brent Hamilton
Bioremediation
process blends petroleum hydrocarbon contaminated
soil with cured MSW/biosolids compost. The
compost also works as an industrial absorbent, at
sites such as truck wash sludge pits and drilling
waste ponds. p58 |
