requirements for curbside collection with manually and mechanically loaded vehicles with a one-person crew are reported in Table 3.10.

Labor requirements for mechanically loaded stationary container systems are essentially the same as for hauled container systems. Where a helper is used, the driver often assists the helper in bringing loaded containers mounted on rollers to the collection vehicle and returning the empty containers. Occasionally, a driver and two helpers are used where the containers to be emptied must be rolled (transferred) to the collection vehicle from inaccessible locations, such as in congested downtown commercial areas. In stationary container systems, where the collection vehicle is loaded manually, the number of collectors varies from one to four, in most cases, depending on the type of service and the collection equipment. While the aforementioned crew sizes are representative of current practices, there are many exceptions. In many cities, multiperson crews are used for curb service as well as for backyard carry service.

Health Issues

The frequency and severity of injuries in the solid waste management industry are very high. The National Safety Council reported that solid waste collection workers have an injury frequency approximately 10 times the national average for all industries, higher than police work and underground mining. Workmen's compensation rates account for about 9 to 10 percent of payroll for all solid waste collectors.

Renewable Energy Eco Friendly

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
