Abstract

This study focuses on the search for the optimal value of the cost per liter of raw milk. The sample included 59 farms with different types of labor, containing 422 elements maintained in different accommodation conditions. The farms are located in an urban area in the country’s capital. This study was essentially based on mathematical methodology close to a variant of the Cobb–Douglas function used by many economists. This made it possible to find expressions of the relationships linking different parameters involved in the evaluation of the optimal value of the cost per raw liter, as well as certain critical values of the number of elements to be determined. The results show that the variation in the cost per liter follows two levels; the first relates to a number of elements between one and ten, where the increase occurs in a linear and progressive manner. The second level concerns the range between 10 and 30 elements. It is characterized by a linear increase and is more accentuated than in the previous case. The results also suggest that a critical number indicates the separation between the two levels. Application of these wastes as fertilizers aligns with the EU Action Plan on the Circular Economy and can contribute to achieving SDGs 2 and 12.
