Test 34 - Solid Waste Transportation

Question 1 ప్రశ్న 1

A municipality uses small vehicles for door-to-door waste collection and large trailers for moving consolidated waste to a distant processing facility. Which interpretation correctly distinguishes collection from long-distance transportation?

A Collection and transportation are identical operations because both involve vehicle movement, regardless of loading arrangements. B Collection refers only to movement inside the processing facility, whereas transportation refers to household segregation. C Collection involves gathering waste from generators or collection points, whereas long-distance transportation primarily involves bulk movement to processing or disposal destinations. D Transportation begins only after waste has undergone complete treatment and no recoverable materials remain.

Question 2 ప్రశ్న 2

A city is evaluating whether to construct a transfer station for waste transported to a regional processing facility. Which criterion provides the strongest engineering basis for the decision?

A Compare complete direct-haul costs with collection-to-transfer, transfer handling and bulk-haul costs, including travel time and operational constraints. B Construct a transfer station whenever the final facility is more than a universally fixed distance from the city. C Choose the arrangement with the largest transfer trailer without considering the quantity of waste generated. D Assume transfer stations eliminate every transportation cost incurred by local collection vehicles.

Question 3 ప్రశ్న 3

A transfer station receives source-segregated wet waste, dry recyclables, sanitary waste and special-care waste. Which operating strategy best supports environmentally sound transportation?

A Mix all streams before loading because long-distance transport eliminates the need for segregation. B Combine sanitary waste with recyclable paper to increase compactor utilization. C Send all special-care waste to an ordinary organic-waste processing line without checking its characteristics. D Provide suitable separate receiving, handling and dispatch arrangements so that the required waste streams reach their appropriate authorized destinations.

Question 4 ప్రశ్న 4

A bulk transport vehicle has a rated waste payload of P tonnes, usable body volume V cubic metres and expected waste bulk density rho tonnes per cubic metre. Which expression correctly gives the maximum permissible waste mass per trip?

A P + rho V, because rated payload and volumetric loading can be added. B The smaller of P and rho V, subject to other applicable vehicle and road restrictions. C The larger of P and rho V, because either limit alone authorizes the heavier load. D P divided by rho V, because vehicle capacity is a dimensionless quantity.

Question 5 ప్రశ్న 5

A municipality is comparing compaction of low-density packaging waste with compaction of dense, inert-rich street sweepings before transport. Which conclusion is most defensible?

A Both materials must experience the same volumetric reduction because they are classified as municipal waste. B Dense street sweepings always benefit more from compaction because their initial mass per cubic metre is already high. C Compaction may substantially improve volumetric utilization for bulky packaging, while dense inert-rich waste may reach vehicle payload limits with relatively little compaction benefit. D Compaction increases the permissible legal payload of a vehicle in direct proportion to the achieved bulk density.

Question 6 ప్రశ్న 6

A proposed municipal transfer station will receive waste from many collection vehicles during concentrated arrival periods. Which design arrangement best addresses operational capacity and environmental protection?

A Size the unloading facility only for the daily average arrival rate and disregard short-term vehicle queues. B Provide an uncovered tipping area connected directly to stormwater drains to eliminate the need for drainage treatment. C Minimize internal circulation space because vehicle queuing does not affect transport productivity. D Provide adequate receiving and loading capacity, safe circulation and queuing space, drainage controls, litter containment and suitable odour management.

Question 7 ప్రశ్న 7

A regional waste-management authority proposes rail-based bulk transportation from a large transfer terminal to a distant processing facility. Under which circumstances is rail transport most appropriate for feasibility evaluation?

A A sustained high waste quantity, substantial haul distance, suitable terminal infrastructure and favorable total handling and transportation costs. B Very small irregular waste quantities with no available rail connection or loading terminal. C Every municipal route independently delivering household containers directly to railway wagons. D Selection based solely on the nominal carrying capacity of one railway wagon without evaluating terminals or schedules.

Question 8 ప్రశ్న 8

A small municipality has a treatment facility close to its collection routes, and collection vehicles can unload there without substantial delay. Which transportation arrangement should be evaluated as the simpler baseline?

A Construct a transfer station and use large trailers even if no measurable long-haul saving results. B Direct transportation by suitable collection vehicles, subject to capacity, operating-time and route assessments. C Move waste first to a remote depot and then return it toward the nearby treatment facility. D Transfer the waste through several intermediate depots solely to increase the number of handling operations.

Question 9 ప్రశ్న 9

A municipal transportation contractor reports low cost per trip but repeatedly operates partially loaded vehicles and experiences long unloading queues. Which performance-assessment approach is most useful?

A Measure vehicle trips alone because payload and waiting time have no effect on transportation efficiency. B Use the largest rated vehicle capacity as the actual carried mass on every trip without checking weighbridge records. C Exclude queuing and empty-return travel from operating-time analysis because neither carries waste. D Assess actual payload utilization, complete cycle times, loaded travel, empty return, unloading delays and cost per tonne transported.

Question 10 ప్రశ్న 10

A proposed transfer station could reduce the number of heavy vehicles traveling to a distant landfill, but its access road passes through a congested residential neighbourhood. Which planning response is most defensible?

A Assume reduced landfill-bound trips automatically eliminate all local traffic and environmental impacts. B Select the site entirely on land cost without reviewing truck access or surrounding land uses. C Evaluate alternative access routes and site layouts, local traffic, noise, dust, litter and operating schedules alongside the long-haul savings. D Exclude community impacts from the engineering comparison because they cannot influence transportation cost.
