While moving along the milk-conducting systems in a milking machine, milk is in contact with the inner surface whose area exceeds 20 m2. That leads to the formation of protein-fat biofilms of contamination, which are a nutrient medium for the development of microorganisms. With insufficiently effective cleaning of these contaminants, in the periods between milking, the number of microflorae located in milk-conducting systems increases by tens of thousands of times. When cleaned with ineffective cleaning agents, mineral elements from milk are adsorbed on the surface of a protein-fat bio-film, which are subsequently compacted, changed, and converted into milk stone. In this case, the technical implementation of milk conducting systems is of critical importance. It has been established that a milk line made from any material is better cleaned with a hot washing solution than a cold one. Thus, with an increase in the temperature of a washing solution from 60 °C to 85 °C, the cleaning time of the milk line is reduced from 9.5 minutes to 1.5 minutes, or by 6 times. It was established that during the washing phase of a milk line there is a significant decrease in the temperature of the washing solution (≈30 %), which reduces the effectiveness of cleaning the parts of the system. Therefore, there is a need to maintain the solution temperature throughout the entire cleaning process. It is proved that the specific energy of adhesion of pollution in water is 2 times higher than that in a washing solution. With an increase in the temperature of the solution for every 10 °C, the decrease in the specific energy of pollution adhesion is on average 13 %. With an increase in the period after the end of milking before washing the milk line, the specific energy of its purification increases. The study reported here could lead improve the productivity of milking machines and the quality of the resulting product. That involves designing milking and dairy equipment from innovative materials.

“…These programs represent additional costs that require investment, and moreover, the low profit margin or even the deficit revealed for reconstituted pasteurized milk circuit limits this type of investment except that in the case where the manufacturer is oriented towards free-priced dairy products with a reduction of certain load categories to improve the cost of the company and other loads recommended through the work of Santos et al (2018) by studying cleaner production techniques in a dairy industry (Southern Bahia-Brazil) based on four axes: Environment and workplace safety; water resource; energy resource; effluents, emissions and wastes, which possible measures to be applied are as follows:…”

Investment challenges in milk sector (Case of a dairy factory in southwest of Algeria): Development prospects

In this work, we are interested in studying the investment challenges of packaged reconstituted milk production in Southwest of Algeria. To reach this objective, we have calculated the cost price of two products (pasteurized milk and fermented milk) which present the main production line of the dairy factory of Bechar, to assess the profitability of the company. The cost price of milk was calculated from the general balance that shows all the movements of the accounts which we have established the table of counting results ‘TCR’ corresponding to the different charges directly related to the milk manufacturing. The analysis of spending data showed that for this factory, the cost price of one liter of pasteurized milk was estimated at 27.06 DZD/L compared to fixed selling price at the dairy factory level (23.20 DZD/L), which reveals a deficit of -3.86 DZD/L (-16.63%), while produced fermented milk showed a profit of +14.65 DZD/L representing a margin of distribution equivalent to (+60.16%) of the cost price that was estimated at 24.35 DZD/L. This study provides a platform which can be used, not only, to define the ability of dairy factory to overcome competitive market challenges, but also the pre-requisite programs (PRP) installation challenges required to implement a quality system promoting the quality of milk and dairy products.

“…In this sense, business practices aimed at sustainable development have multiplied in recent years. Owing to the relevance of the theme, several studies have sought to shed light on the issue of sustainability in organizations with various end activities, such as those in the water and sanitation (Di Agustini & Giannetti, 2018), textile (Amaral et al, 2018), furniture , dairy (Santos et al, 2017), energy (Jugend & Figueiredo, 2017), and agriculture (Sellitto & Hermann, 2016) sectors.…”

Evaluation of the socioeconomic and environmental sustainability of banking institutions in Brazil using the Analytic Hierarchy Process with ratings approach

et al. 2021

Large banking institutions play an important role in sustainable development, especially owing to their size and capillarity. Therefore, the objective of this study is to compare sustainability indicators (economic, environmental, and social) published in the reports of some of these institutions that operate in the Brazilian market. The four banks selected for this study were the ones that published their sustainability reports in the 2017 Global Reporting Initiative standard, and that comprised the portfolio of the Corporate Sustainability Index, promoted by “Brasil, Bolsa e Balcão,” in 2018. These banks were Banco do Brasil, Bradesco, Itaú, and Santander. The analytic hierarchy process (AHP) with the use of ratings was used to carry out the research. After elaborating on the hierarchical structure of the problem, specialists, who were researchers in the field of sustainability, were required to weigh the degree of relevance of each of the indicators analyzed in this study. A ranking of the selected banks was then obtained in relation to their sustainability performances, which was based on the weights given to each indicator and the data available in the sustainability reports of each institution investigated. The banks were ranked in the following order: Itaú, Santander, Bradesco, and Banco do Brasil. The results of this study showed that there is room for evolution in relation to sustainability, mainly in the social department, in the banking sector. The AHP method with the use of ratings proved to be efficient, especially because it allowed for the weighing of the evaluation criteria and sub-criteria; this proved the usefulness of the method in comparing companies with regard to their sustainability performance.
