Congressional District of University where the research is to be conducted
Statement of critical regional of state water problems
Currently, the State of Hawaii is generating about 4.5 x
106 lbs. (2 x 106 Kgs) of animal waste (including both
confined and unconfined animals) per day. This includes 88% of daily and beef
and 12% of hog and poultry manures. These manures are approximately equal to
two times the organic waste generated by the population in the start of Hawaii.
The pollution hazard to Hawaii's environment by animal waste is certainly very
high. If animal waste is not properly treated/managed, it would pose a serious
threat to the water quality for drinking and public use. The state and federal
agencies are establishing and enforcing more stringent regulations on the
disposal of animal wastes. In realizing the associated problems (such as odor
generation, scheduled removal of sludge and effluent, risk of contamination of
groundwater due to seepage and run-off of nutrient due to stormwater) of
operating the anaerobic lagoon for the swine wastes management system >in
>Hawaii, the Dept. of Biosystems Engineering of the University of Hawaii has
conducted various animal management researches in the past decade. Cost
effective and and environmentally sound treatment alternatives for highly
concentrated animal wastes (including swine and poultry wastes) have
successfully developed in laboratory soak (see relaxed research list). Although
all of these highly effective treatments and utilization systems have been
proven in laboratory scale, it is absolutely necessary to fabricate and operate
a prototype to test as effectiveness as a system. This prototype will be cost
effective,d and easy to assemble at the production site. Most of all, the
system will be allowed to make it possible for not only hogs, but dairy and
poultry operations and responsibility without bearing regulatory and economic
burden.
Statement of results of benefit:
After pertinent data is collected and evaluated, the
livestock producers will be able to determine what animal waste management
system is the most appropriate and economical for their specific farming
operation, location and future planning. Also, it may be possible to explore
the potential for a joint animal production/ processing municipal cooperation
and treatment system.
