This paper considers and analyzes a relevant issue of treatment of disturbed soils. The equipment to carry out various processes of mining reclamation of waste heaps and quarries with a significant reduction in the level of environmental risks through the operation of an energy-saving small-sized apparatus has been designed. The use of the developed soil reclamator is also adequate for pre-sowing and other types of agrotechnical tillage, plant care in agricultural fields, as well as in areas with a heterogeneous landscape. The functionality of the unit is able to provide energy autonomy and automation of the technological process. The low weight of the device makes it possible to reduce the pressure on the soil, which minimizes the environmentally hazardous formation of dust during the treatment of waste heaps, the destruction of its structure, the machine degradation of the fertile layer during the processing of all types of territories. The device also reduces the risk of fertile soils slipping from the slopes of mine dumps due to the fact that the soil reclamator is self-propelled and functions without the need to involve a heavy tractor. The mathematical modeling of the operation of the proposed technical support for the treatment of waste heap reclamation in comparison with the opposed analog proves the ecological and economic efficiency of the eco-adaptive soil reclamator. The average value of profit ratios, when using the proposed soil reclamator, is 121.82 % higher than with the involvement of opposed equipment. Indicators of the negative environmental impact of the designed equipment are 100 % lower than the environmental impact when operating the analog. The proposed technical solution can be effectively applied both in schemes of sanitary cleaning of settlements, and in the process of modernization of agricultural machinery

This article focuses on the importance of a methodological approach to building a management system for industrial recovery in regions and the integration of skilled labor into the regional economy even during wartime. The purpose of the article is to provide a scientific justification for the impact of internal and external environments on the regenerative processes in the industrial economy during the period of martial law and after the cessation of hostilities, as components of the system for restoring the industrial potential of regions. A comprehensive and interconnected examination of the challenges facing the state today with the systemic problems of the development of the industrial economy in the pre-war period lays the foundation for successful transformational transformations and the speed of regenerative processes of economic and social recovery. The author claims that the economic-social, economic-ecological and social-ecological components of recovery processes are closely related and affect the final result - industrial recovery today and sustainable development of regions and the state in the future. The author notes that transforming the challenges of the external environment into opportunities in building the industrial recovery system through the application of a management system embodies an additional resource for optimizing and accelerating the regenerative processes in the industrial economy. This requires a broad, comprehensive analysis of the interplay between internal and external environmental factors for transformational changes of external challenges into additional opportunities, thereby enhancing the hidden, existing, and underutilized potential of regions through the construction of quality coordination processes in the industrial recovery system. The article elaborates on the theoretical and methodological justification for the impact of effective management and coordination approaches on the restoration processes to achieve the ultimate goal – the recovery of the industrial economy and sustainable development of the region, determining optimal models for operational monitoring of process progress, studying the impact of cutting-edge technologies on recovery processes, as well as overcoming technological gaps and creating conditions for the return of skilled migrants to Ukraine.

This research systematically evaluates a biomass combustion furnace, focusing on the influence of varying combustion chamber casing materials. The study employs controlled laboratory experiments to investigate the impact of different casing materials on combustion performance, thermal efficiency, and practical applications such as water boiling capacity. The research uses distinct materials, including clay, steel, and aluminum, for combustion chamber casings while maintaining consistent dimensions. The central experimental apparatus, an aluminum stove, was meticulously crafted, adhering to precise measurements. Coconut shell briquettes served as the primary fuel source for this investigation. The results reveal intriguing dynamics in combustion behavior. Notably, the choice of combustion chamber casing material significantly affects fire temperature, sleeve wall temperature, thermal efficiency, and the ability to boil water. Clay emerges as a standout performer, achieving high thermal efficiency (56.8 %), substantial water boiling capacity (25 liters), and efficient fuel consumption (1.28 kg of burnt briquettes). However, steel casing materials excel in generating the highest fire temperatures (up to 557 °C), underscoring their exceptional heat-conducting properties. Aluminum has fast temperature responses but may not retain heat like clay. The findings help optimize biomass combustion furnaces and associated applications. Material selection is crucial to attaining combustion goals like efficiency, temperature generation, or practical heat. These discoveries could lead to more efficient and ecologically friendly biomass combustion systems for sustainable energy and resource use
