Plastic mulch provides a range of benefits including helping modulate soil temperature, reduce soil erosion, evaporation, fertilizer leaching and weed problems and increasing the quality and yields of the product. But when the crops are harvested, plastic mulch needs to be removed from the ground for disposal. Otherwise, these wastes are mixed with the soil and have a negative impact on yields by reducing the access of nutrients and moisture in the soil. The purpose of the current study is, therefore, to propose a roller for plastic mulch retriever which is applicable when the crops are harvested, and the plastic mulch needs to be removed from the ground for disposal. The winding mechanism of the plastic mulch retriever performs the main function and must have the high-quality performance of the winding operation in the removal technology. Research based on requirements of tensile strength test method and changes of strength characteristics of plastic mulch from various factors under natural conditions. The coefficient of compaction of the used plastic mulch (Krel), was the ratio of the diameter of the standard plastic mulch which was wound in the factory to the diameter of the used plastic mulch during the winding.

The interior microclimate is a collection of all physical and chemical parameters of rooms affecting the human body, objects and a building. The values of these parameters are directly influenced by the type of installations in the building, such as heating, ventilation and lighting. While shaping the internal environment of the museum building, we should include the requirements of the exhibits and the comfort of people staying in the room, simultaneously reducing energy consumption. This article is a case study of a chosen museum including the measurements of the parameters shaping the interior microclimate.
