The objective of this present study is to investigate the efficiency of chitosan as an adsorbent to treat egg processing industry wastewater. Parameters affecting the effluent treatment process such as pH, chitosan dosage, settling time and initial chemical oxygen demand (COD) concentration on the reduction percentage of turbidity, COD and biochemical oxygen demand (BOD) were studied. Optimum condition was found to be pH of 4, chitosan dosage of 1.1 g L-1 and settling time of 40 min respectively. The maximum reduction percentage of turbidity, COD and BOD were found to be 94 %, 88 % and 83 % respectively. The effective adsorption process was confirmed by FT-IR spectra analysis. The experimental data was analyzed by different isotherm and kinetic models. Langmuir isotherm type I model was satisfactorily described the adsorption mechanism and the rate of COD reduction followed the pseudo-first-order kinetic model. A four factor, three levels Box-Behnken response surface design was employed to develop second order polynomial mathematical models from the experimental data.

AbstractThis study investigated the effects of seaweed extract (SWE) made from the brown algae Durvillaea potatorum and Ascophyllum nodosum on plants and soil. The application of SWE to soil growing tomato plants showed dual effects. SWE comprehensively improved tomato plant growth (flower clusters, flower number, fruit number, root length, root and shoot dry weight, SPAD) and increased plant productivity (yield and quality). Similarly, SWE application effected soil biology at the soil root zone by increasing total bacterial count and available soil nitrogen and impacting bacterial community diversity with an increase in certain bacterial families linked to soil health. A broader understanding of the effects of SWE on the plant-soil ecosystem may offer breakthrough approaches for sustainable food production.

Processing Industry

Background. The total production of beef and pork is declining from year to year. The study of development trends in the meat industry of Ukraine will help to outline the prospects for the successful realization of potential opportunities for production expansion. An analysis of recent research and publications has shown that despite some scientific developments, dynamic changes in the meat processing industry require constant monitoring of unresolved issues. The aim of the study is to analyze the current state and characteristics of the meat processing industry of Ukraine on the basis of analytical research in general and in the context of its innovation activities in particular. Materials and methods. Research methods were used: monographic, statistical groupings, correlation-regression analysis, graphical. Results. Analysis of the dynamics of industrial meat production shows that beef and veal occupy the least share in it. The basis for ensuring the economic balance of production and economic relations of economic entities is the consistency of supply and demand for raw meat and products of its processing. For the successful development of the industry, the state must protect and stimulate domestic producers; to harmonize domestic standards of safety and quality of products in accordance with international ones. The innovative development of the meat market requires adequate investment support, and the stimulation of investment activity should be considered in the context of the strategy of development of the national economy on an innovative basis. Conclusion. Livestock production in general and meat in particular are one of the leading sectors of agriculture. In recentyears, there have been some trends in the dynamics and structure of meat production and consumption in favor of cheaper poultry meat. The reason for this is the reduction in production; increase in retail prices for all types of products; low incomes of the majority of the population. A necessary condition for the sustainable development of the meat processing industry is the introduction of European regulations on product quality and safety standards; introduction of resource-saving technologies at enterprises; reconstruction of enterprises; provision of production facilities with domestic raw materials.
