THESE FUNDS supported in part a National Conference on Solid Waste to stimulate research in this field. Recognition was given in the long-range aspects of the solid waste disposal problem and the urgency of working toward a solution. The conference, held for two and one-half days in December 1963 in Chicago, reviewed the problem of solid wastes in the United States. Some 36 papers and summaries were presented by authorities in the field.

The conference covered research needs in waste characteristics, waste collection and transportation, and waste treatment and utilization, with efforts directed toward

encouraging young researchers to meeting the research needs in this field.

The budget covered mainly travel and per diem for program participants and Study Section members, travel for 30 young researchers, travel for three foreign scientists, preparation and printing of the program, stenotype recording, and transcription and publication of the proceedings.

Terminated: June 1965

PROCEDURE: Utilized the Harvard incinerator-boiler as a prototype after completion of the customary manufacturers acceptance tests and investigated the decontamination that may be attained in a specially designed combination incinerator-boiler.

PROFESSOR ROBERT C. MERZ Department of Civil Engineering University of Southern California Los Angeles, California

PURPOSE: To expand a continuing program for obtaining field information on factors controlling volume reduction in a sanitary landfill, with emphasis on physical and biochemical phenomena.

PROCEDURE: The various landfilling techniques are being carried out for this project in a large landfill operated by the Los Angeles County, California Sanitation Districts. Six landfill study cells, about 50 feet square by 20 feet deep, were originally constructed in landfills, with three special purpose cells constructed later.

In these cells, the effects of soil admixtures, compaction, aeration, moisture, and temperature and various sanitation studies are being evaluated. Each load of refuse used is weighed and categorized as to composition.

Efficient utilization of landfill sites is an important aspect of this study.

This research has received Public Health Service support since May 1960.

PURPOSE: The development and perfection of a mathematical model to simulate the municipal refuse collection and disposal problem. This model enables the engineer-designer to predict the behavior of a wide variety of proposed designs quickly and accurately, and thus to predict an optimum solution based upon more complex criteria than it has previously been possible to evaluate.

PROCEDURE: Preliminary collection and analysis of refuse disposal unit operations cost data and the expected type and amount of pollution resulting from the various collection and disposal methods were obtained from literature. Data also were obtained by communication and direct interview with responsible municipal authorities, public health workers, and consulting engineers. A mathematical simulation analysis of refuse collection and disposal systems was developed. A computer program capable of considering stochastic variations in the system parameters was written for the daily route method

of refuse collection. Initial computations served to delineate the relationships of the several performance parameters (over-all collection efficiency, length of workday, etc.) to the characteristics of the system (average daily quantity of refuse, daily variability in the quantity of refuse, truck capacity, etc.).

This research has received Public Health Service support since September 1962.
