JUSTIFICATION OF TECHNOLOGY FOR THE MAXIMUM INVOLVEMENT OF WASTE FROM CONFECTIONERY PRODUCTIONS IN THE ECONOMIC TURNOVER IN THE REPUBLIC OF BELARUS

Abstract

Wastes of confectionery production in the Republic of Belarus at the moment are egg shells, spoiled, contaminated food, food containing harmful food additives. Based on the statistical data of the Republic of Belarus, it was found that the total amount of waste generated by the confectionery industry and eggshell from 2015 to 2020 increased by 86,6 %. These generated wastes of confectionery production in our country are currently practically not processed and are sent to a landfill as part of municipal waste, thus increasing environmental pollution. Therefore, there was an economically, technologically and environmentally justified need to develop recommendations for the management of confectionery waste. On the example of one of the largest confectionery enterprises of the Republic of Belarus, the use of technological equipment was investigated and justified - a drum dryer for processing eggshell waste. To obtain high-quality raw materials (eggshell flour), the main parameter of the plants is the ability to maintain high temperatures. This characteristic served as the main parameter for choosing a drum set. Calculations have shown that the cost of collecting and transferring waste to processing enterprises is much less than the cost of drum dryer equipment alone. Also, such installations require additional equipment with various expensive components. In addition, the cost of preparing the site on which the equipment will be installed, commissioning and regular sanitary maintenance with regular technical inspections and repairs of the installation were taken into account. Considering the volumes of generation of these wastes at enterprises and in the whole country, it is not advisable for the enterprises of our state to carry out individual processing of these wastes within production. It is recommended to transfer egg shell waste for processing to third-party specialized enterprises. This decision will help reduce the amount of eggshell waste transferred to landfill sites, and will also allow processors to pay for shell processing plants by selling the resulting products.
