One of the main problems in mutual relations of a big city and suburban territories in sphere of solid waste management is «the scale problem» – an incommensurability of quantity of a waste made by a big city with natural ecological capacity of suburban territory that dictates necessity of development of special mechanisms of realization of interterritorial interactions for sphere of the solid waste management of big city.

For practical realization of system of mutual relations of a big city and suburban territories (city agglomeration) in sphere of solid waste management it is necessary to deduce,
first, a considerable share of a stream of a city waste for limits of agglomeration and,
secondly, to provide possibility civilized, and, including, ecologic-economically well-founded recycling of this waste.

It is a question not so much of a solid household waste, how many about a building and pulling down waste, basically – about building earth which volume reaches tens thousand cubic meters a day. These volumes surpass logistical possibilities, both motor transport-carrier, and a residential suburb, as territory-acceptor.

Besides, from the point of view of economy, a shoulder of automobile transportation of a waste more than 50, (in rare occurrences – 100 kilometers) is nonsense. The exit from a developing situation sees in introduction in logistical solid waste management system of city agglomeration of other vehicles providing sharp increase of load-carrying capacity and lengthening of a shoulder of transportation that would allow to use as territory-acceptor the districts removed from city agglomeration with conditions available there suitable for recycling, for example, building earth.

As an example we will consider application of a railway transportation for transportation building earth from St.-Petersburg in settlement Kuznechnoje (Leningrad region) on purpose of recultivation the developed granite open-cast mines on distance about 200 km. The overload earth from special cars in railway cars-dumpcart is carried out from platforms, with application of the known technologies providing uniform loading of platforms and absence of a contamination of a rail way.

Usually the overload economically does not justify, but in this case operation on a site the manufacturer of a waste (usually – a building site) – the car practically does not differ from operation on a site the manufacturer of a waste – station of the overload, accepted in practice of solid waste management, and almost not worsening economic indicators. The loaded structure delivers building earth in settlement Kuznechnoje, where the branch line is in immediate proximity from a reception place for earth – the developed open-cast mine (or the developed part of an open-cast mine), a subject recultivation.

For unloading maintenance special cars, probably, there will be a necessity of erection of retaining walls, stationary, or time, made with application of typical technique and designs. The capital expenses directed on erections of retaining walls, considering huge volume overloaded ãðóíòîâ, will not render some serious influence on economy of all logistical chain. Return flight the structure can carry granite rubble, elimination, sand, other passing loose cargoes to St.-Petersburg – as a result the process economy only wins.
