5. prioritize projects for consideration in an annual program.

4.3.14.1 Sharing ideas. Lessons learned at one installation will save time and effort at other installations. An annual Tri-Service meeting on the sole subject of RRRPS would be an excellent way of presenting useful information, especially to new programs. Such a meeting should show a high return on investment simply by warning inexperienced bases about common pitfalls.

4.3.15 Audits

4.3.15.1 Any RRRP can be subject to an internal service audit or an audit by the Government Accounting Office.

4.3.15.2 The overall objective of an audit is usually to evaluate MWR participation in the RRRP and the internal controls in place to manage the funds generated by the program. Specifically the audits will

1. determine whether sound business practices were followed in
establishing the RRRP.

2.

evaluate the effectiveness and efficiency in managing the RRRP to determine whether procedures promote revenue maximization and cost minimization.

3. evaluate procedures to account for RRRP revenue to determine whether accountability is maintained from sale to receipt of cash and whether income reporting is consistent throughout the military.

4. determine whether all costs incurred in generating RRRP revenues are reimbursed prior to project funding and whether RRRP funds are being used in accordance with the intent of Public Law 97-214.

5.

6.

determine whether any abuses of Public Law 97-214 are occurring. The intent of the law is clearly to allow only revenues from the sale of scrap to accumulate in RRRP accounts. Reusable personal property is NOT to be sold as scrap.

determine whether installations with qualified RRRP's are receiving goods from installations without RRRP's. This practice is not recommended.

Each installation shall establish its own RRRP even if

some support is required from another installation.

4.3.16 Waste Segregation Options

4.3.16.1 Segregating Wastes. The mechanics of segregating recyclable materials falls between two extremes: source separation and disposal site separation. Source separation is defined as the setting aside of one or more recyclable materials, such as paper, cans, or glass, from refuse. This must be done at the point of generation by the discarding unit before the materials become mixed into the solid waste stream.

4.3.16.2 Disposal Site Separation. Disposal site separation generally uses mechanical equipment to separate recyclable materials from other

post consumer wastes. The simplest form is a conveyor belt manned by laborers who do the actual separation.

4.3.16.3 Separation of materials at final disposal sites generally requires a large investment in equipment and a large, steady supply of raw material to justify the equipment. Likewise, markets for the recovered materials must exist. For these reasons, few military installations practice disposal site separation. Techniques are mentioned here because some bases will utilize them in some form and future trends may show more extensive use because of increased costs for landfilling and incineration.

4.3.16.4 Recovery of Materials at Final Disposal Sites. This type of recovery is distinguished from source separation in that recoverable materials enter the waste stream and are mixed with nonrecoverable solid wastes. This method will generally require the use of specialized equipment or machines not normally found in the military supply system.

4.3.16.5 The overall success of a mechanized material recovery facility depends on the technologies utilized. Ferrous metal recovery has been proven effective at several locations, whereas aluminum recovery has achieved a less successful track record. For economic and health reasons, mechanically recovered paper is currently used almost exclusively for the production of refuse-derived fuel (RDF) rather than fiber recovery. As a result, technologies designed to recover fiber have received relatively less attention. Glass recovery technologies have achieved limited success; more than aluminum, less than ferrous metal.

4.3.16.6 The technology for separation of materials from military post consumer solid waste is generally used in conjunction with energy recovery systems. Several techniques are listed in Table 4-3-16A. The more common ones are discussed below.

4.3.16.7 Hand picking of recyclables from conveyors prior to discharge into transfer trailers or processing machinery is frequently practiced.

4.3.16.8 Magnetic separators usually consist of a belt, drum, or pulley with a magnet used to attract and remove magnetic materials from refuse or other materials (Figure 4-3-16A). At military industrial installations, cranes with electromagnetic hooks (Figure 4-3-16B) can be used to separate magnetic materials into large sorting bins.

4.3.16.9 Eddy current separators are used to separate aluminum and other nonmagnetic metals using the properties of a magnetic field as a method of sorting. An alternating current is passed through a piece of metal causing it to become temporarily magnetic and thus deflected and separated.

4.3.16.10 Heavy media separators use a suspension of finely ground, dense minerals in water. When the mixture of glass, aluminum, and other nonferrous metals is immersed in the liquid, the fluid density can be controlled so that the aluminum and glass float while the other metals sink.

4.3.16.11 Equipment used in the paper industry can pulp waste paper and separate foreign matter. Hot water and agitation are used for pulping
