What is it about?
MSWs in the form of pressed briquettes wrapped in polyethylene film can be transported by road, water or rail. Optimal solid waste delivery schemes are based on intermodal transportation, which includes several transshipment of solid waste from one type of transport to another. An ideal container for MSW, providing such overloads and having a minimum weight, could be standard containers, but the specific features of MSW (strong smell, methane release and hydrogen sulfide, liquid flowing from briquettes) require the development of a specialized container based on a standard container, but with additional properties of tightness and automation of loading and unloading processes. The purpose of this work is to substantiate the design of the designed specialized container for transportation of solid waste by rail.

Why is it important?
We have proposed the design of a container with an external steel frame and an internal insert of vacuum honeycomb panels, inside which a conveyor is located. Conveyor is made in the form of cylindrical rollers driven by chain drive and four electric motors. The conveyor allows you to load and unload solid waste briquettes without finding workers inside the container. The thermal insulation properties of the container are provided by vacuum honeycomb panels which form a sealed container body.
Perspectives
In the developed design of the specialized container, the outer dimensions correspond to the standard dimensions of the container 20 DC, the inner dimensions of the cargo compartment of the container are 4500?1300?2300 mm, which makes it possible to accommodate eight stacks of MSW briquettes with a briquette size of 1200?1100?1100 mm and a total weight of 15 tons. According to the calculations made, the average specific thermal resistance of the walls of a specialized container was 1.48 (m2·K )/W, which ensures the requirement to prevent freezing or thawing of solid waste during transportation.
