Proper municipal solid waste management is relevant in the context of sustainable development of modern cities. It is especially essential for developing countries. The organic fraction of municipal solid waste is significant and biodegradable. Extraction of organic matter and its composting is classified as the most preferable approaches of the strategy of sustainable management of municipal solid waste. Composting technology is characterized by its economic efficiency compared to other alternatives and is most commonly used worldwide. In Ukraine, there is no practice of municipal solid waste composting. For the first time, the pilot project on the practice of composting the organic component of municipal solid waste was introduced in Ukraine in the Lviv city. The paper presents the results of research of physical and chemical properties, agrochemical parameters and heavy metals content of the formed compost in accordance with the Ukrainian Standard of fertilizers. Due to received data, the city's municipal solid waste compost can be used as fertilizer in agriculture. [ABSTRACT FROM AUTHOR]

In the article, one presents the results of the inspection of the production building and the calculation of the bearing capacity, strength and stability of the part of the production building with the front wall. Conducting the survey, the building was partially dismantled, which changed the design calculation scheme of the frame. In addition to removing the columns and crossbars of the adjacent spans, the nature of the connection of the existing crossbars to the K4-3 columns was changed from rigid to hinged one. The customer partly wanted to dismantle the remains of the existing building and leave only the longitudinal brick wall but based on a visual and instrumental survey, theoretical calculations and the results of modeling the structures in calculation software complexes, we offered the customer the following options for preserving the longitudinal wall of the production building: Option 1: Preservation and dismantling of covering plates and ceilings. Option II: Complete dismantling of all structures (except for front wall structures) with reinforcement of longitudinal front wall columns. [ABSTRACT FROM AUTHOR]
