Waste Management
http://www.agen.ufl.edu/~roger/ABE5707C.htm
Fall
Semester, 2006
I. Agricultural Waste Management, 3 credits.
II. Course Description - Engineering
analysis and design of systems for the collection, storage, treatment,
transport, and utilization and disposal of livestock and other agricultural
organic wastes and wastewaters. Field trips to operating systems and laboratory evaluation of
materials and processes.
III. Objectives:
1. To
familiarize students with the physical, chemical and biological properties of
livestock wastes and their impact on the environment.
2. To
develop the students' abilities to analyze and design systems for the collection,
handling, treatment and utilization of these wastes.
3. To
provide familiarization with operating waste management systems via field
trips.
IV. Format - Two lectures and one
laboratory per week. Laboratories will
be field trips to commercial livestock production facilities, agricultural
processing plants, or other waste treatment and handling facilities. Lecture will be conducted when a field trip
has not been scheduled during the laboratory period.

Field Trip Report Format
The field trip report should be a summary of
information gathered at the facility which was visited. It should include any facts and observations
which you might need at a later date to do a design problem or to prepare a
more elaborate or comprehensive report.
It should be well-organized and neat (preferably typed or printed). It may also include some analysis of the
facility, perhaps resulting from some routine calculations, or it could include
suggestions for improvements in physical facilities or operational procedures.
A suggested outline might be as follows:
1. Title
(name of facility, location, date of visit, your name, etc.) This need not be a separate page.
2. Description
of the facility (general layout, operation, areas visited, names of people to
contact, etc.) Hand-drawn sketches may
be helpful.
3. Data
summary (animal populations, processing or waste treatment system capacity,
animal weights, age, water use, wastewater flow, equipment sizes, etc.)
4. Sketches
or drawings (facility layout, flow diagrams, etc.), if not included in part 2.
5. General
observations (good or poor management, suggestions for changes in practices,
additional facilities or modifications needed, etc.) Be
critical.
