Onsite Handling And Storage

Where solid waste is temporarily stored on the premises, between collections, an adequate number of suitable containers should be provided.

Low-Rise Residential Areas

To a large extent, the type of container used for the collection of residential solid waste will depend on the type of collection service provided, and whether source

Separate collection service for (1) source-separated recyclable materials, (2) source-separated compostable materials (i.e., food and yard waste), and (3) nonrecyclable solid waste a The method of waste preparation for collection is often selected for convenience and efficiency of collection services and subsequent materials processing activities.

FIGURE 3.3 Typical containers used for collection of residential solid waste: (a) source-separated recyclable materials are placed in three separate containers (one for paper, one for glass, and one for cans and plastics), residual nonrecyclable wastes are placed in separate containers, and yard wastes are place in the street for collection with specialized collection equipment; (b) commingled mixed wastes in a single large (90-gal) container.

separation of wastes is employed (see Table 3.8). The various types of containers used for residential service are illustrated in Figure 3.3.

Low- and Medium-Rise Apartments

Large containers located in enclosed areas are used most commonly for low and medium-rise apartments. In most applications, separate containers are provided for recyclable and commingled nonrecyclable materials. A typical example is shown in Figure 3.4.

Curbside collection service is common for most low- and medium-rise apartments. Typically, the maintenance staff is responsible for transporting the containers to the street for curbside collection by manual or mechanical means. In many communities, the collector is responsible for transporting containers from a storage location to the collection vehicle. Where large containers are used, the contents of the containers are emptied mechanically using collection vehicles equipped with unloading mechanisms.

High-Rise Apartments

In high-rise apartment buildings (higher than seven stories), the most common methods of handling commingled wastes involve one or more of the following: (1) wastes are picked up by building maintenance personnel from the various floors and taken to the basement or service area; (2) wastes are taken to the basement or service area by tenants; or (3) wastes, usually bagged, are placed by the tenants in a waste chute system used for the collection of commingled waste

Commingled Waste Examples

FIGURE 3.4 Typical example of containers used for low- and medium-rise apartments. Large containers are used for solid waste to be disposed of in a landfill. The smaller containers in front of the enclosure are used for: (1) glass, tin can, aluminum cans, and plastic containers (type 1 and 2) and (2) recyclable paper and paperboard products.

at a centralized service location. Typically, large storage containers are located in the basements of high-rise apartments. In some locations, enclosed ground-level storage facilities will be provided. In some of the more recent apartment building developments, especially in Europe, underground pneumatic tran sport systems have been used in conjunction with the individual apartments chutes.

Commercial and Institution

Bulk containers or solid waste bins are recommended where large volumes of solid waste are generated, such as at hotels, restaurants, motels, apartment houses, shopping centers, and commercial places. They can be combined to advantage with compactors in many instances (see Figure 3.5). Containers should be placed on a level, hard, cleanable surface in a lighted, open area. The container and surrounding area must be kept clean, for the reasons previously stated. A concrete platform provided with a drain to an approved sewer with a hot-water faucet at the site to facilitate cleaning is generally satisfactory.
