Collection route

Haul distance Although minimum haul distances are desirable, other factors must also he considered. These include collection-route location, types of wastes to he hauled, local traffic patterns, and characteristics of the routes to and from the disposal site (condition of the routes, traffic patterns, and access conditions). 

Information on collection, one of the most costly functional elements, is presented in four parts dealing with (1) the t es of collection services, (2) the types of collection systems, (3) an analysis of collection systems, and (4) the general methodology involved in setting up collection routes. 

The Council for Solid Waste Solutions (CSWS) conducted a collection analysis for the Minneapolis, MN area in 1990. The impact of plastics collection on five existing curbside collection recycling programs was evaluated in terms of additional collection time, vehicle capacity and additional cost. The collection routes were as follows ...

The Madison, Wisconsin pilot, which collected recyclables commingled in clear plastic bags, recorded the collection times shown in Table 4.4. The average collection time for all four collection trucks utilized is about 1 minute per stop. This does not include dumping time, break time, and other time spent not related to collection, but does include time driving to and from the collection routes. No separation of materials was performed at curbside. 

Collection complexes belonging to echelons located at the upper part of Fig. 2, such as gas stations, car shops, and auto accessory stores, are used as subjects, and the study investigates a collection device at each complex in the same echelon, a collection route between collection complexes, and routes to different echelons, such as transshipment and storage complexes and intermediate treatment factories.

Next, the density function model by Okabe and Suzuki will be used in order to search the optimal location for the collecting center of waste treatment facilities in Chiba. Moreover, the collecting routes from intermediate treatment facilities to the collecting center will be found by using a development programming, and a result of routes will be shown by computer simulation. Increasingly, collecting distances, units of transportation (quantity and traffic of transportation), will be calculated. 

In order to find collecting routes from the collecting center to all other treatment facilities, route-first cluster-second method is consulted in this study.

Figure 2 shows the results of the collecting routes from the Y treatment facility to all other treatment facilities in Chiba. 

From the above result, the total distance of the collecting routes which are shown in Fig. 2 is 617 km., and the transportation quantity is about 506.2 x 10" t km. 

As can be seen from the result, the examination revealed that efficiency of collection in intermediate treatment facilities can be improved from cmrent simation by simulation of locations and collecting routes which are shown in Figs. 2 and 3. 

The much lower delivery of industrial waste to the MSW collection route where large-volume road containers are substituted by curbside low-volume bins and bags.
