A СOMPREHENSIVE APPROACH TO PREVENTING MOLD GROWTH OF SOLID ORGANIC WASTE FROM CONFECTIONERY PRODUCTION AS THEIR SUSTAINABLE MANAGEMENT ELEMENT

Waste sustainable management involves both minimizing their quantity by improving technological processes and using waste as resources. A large amount of solid organic waste from confectionery industries contains food elements that can be used as additives in compound feeds production. This reduces compound feeds cost without losing their quality, and also provides for the secondary use of solid organic waste from confectionery industries, which corresponds to the generally accepted waste management hierarchy. The main limiting factor for this waste type using in compound feeds is mold fungi rapid development, which is due, among other things, to an increase in the waste humidity when stored in an open manner at industrial sites. The aim of the work was to research developed integrated approach effectiveness to increase the shelf life without the mold fungi appearance for solid organic waste from confectionery industries. The following research methods were used in the work: field – to observe the mold fungi development in real storage conditions of solid organic waste from confectionery industries in an open way; laboratory – to determine the moisture content of waste at different times according to DSTU 4910:2008 and sanitary and mycological waste assessment. The use of the simplest measures to reduce the atmospheric contact precipitation with solid organic waste from confectionery industries – canopies – allows us to increase the period until the mold fungi appearance by 20 or more days, depending on the waste composition. Faster mold fungi development is characteristic of waste that contains more than 50 % wafers with fat filling. Solid organic waste from confectionery industries treatment with humic acids alkaline solution obtained from brown coal increases the period until the mold fungi appearance by an average of 50 days. The two methods combination is effective for increasing the shelf life of solid organic waste from confectionery industries before their use in compound feeds. Thus, it is possible to increase the share such waste use in compound feeds. The proposed integrated approach to increasing the shelf life of solid organic waste from confectionery industries allows to increase the waste share that is suitable for secondary use in compound feeds. The humic acids alkaline solutions using as a bactericidal measure for solid organic waste from confectionery industries is justified from the sustainable approach for brown coal using, allows to increase the nutritional value of the final compound feeds and reduces energy costs for mold fungi elimination.
