“…The largest spread between minima and maxima values can be found in the eutrophication figures. The calculated figures for dairy farming in Luxembourg are consistent with the range of values from literature [17][18][19] concerning all product-related figures as well as surface-related figures of carbon footprint and energy consumption. Only in the case of surface-related figures of acidification and eutrophication, it was not possible to find values in the literature because relating these figures to the farm area is unusual.…”

The aim of the study was to investigate both environmental and economic performances of Luxembourgish dairy farms in order to assess possibilities and limits of improving economic competitiveness via increasing environmental efficiency. In the environmental field, four LCA impact categories (carbon footprint, energy consumption, acidification, eutrophication) were analysed, while in the economic field, costs, incomes and profit of the farms were investigated. A main result was that a sustainable dairy production with less environmental impact in all considered categories is also of advantage in terms of farm competitiveness. The most efficient farms reach also the highest profit. The case study proves that a high environmental performance is not only of advantage in terms of economic competitiveness, but is even a necessary prerequisite for best economic performances.

“…Life Cycle Assessment (LCA) is a widely used technique for evaluating and quantifying the sustainability profile of products, analyzing and measuring the impacts generated both in the manufacturing processes and in their use, in order to consider the entire production chain and its relationships with the environment. In this context, LCA allows a complete understanding of the environmental impacts, enabling the search for improvement at different points of the production process and optimizing environmental management and the reduction of impacts associated with the production chain (Basaia, 2020;Brandalise;Bertolini, 2015;Seó et al, 2017;Silva, 2022).…”

“…The circular economy and regenerative agriculture are concepts still little explored that preach sustainable practices, which can be adopted to mitigate environmental impacts attributed to the dairy supply chain. Life cycle assessment (LCA) has presented itself as an alternative for the evaluation of production chains and the identification of critical points to be improved, and recent studies have made use of this tool to assess the environmental sustainability of farming systems (Basaia, 2020;Seó et al, 2017;Silva, 2022).…”

Dairy farming has great socioeconomic importance in Brazil, and the last decades have registered a constant evolution of the production chain, seeking to increase quality and production efficiency. In this context, the production systems have intensified and adopted new technologies. The Compost Barn system has stood out as a confinement option for dairy cattle, for its lower implementation cost than other confinement systems and the possibility of giving an adequate destination to the animals' waste. Besides the search for greater production efficiency, the environmental sustainability of agricultural systems has been increasingly discussed, and dairy cattle farming is associated with many potential environmental impacts. It is essential to identify and mitigate them for the consolidation of a production chain socially fair, economically viable and environmentally correct. Thus, this literature review aims to evaluate the economic and environmental feasibility of the Compost barn system within the national dairy farming scenario.

“…The raw milk inventory presented by Ecoinvent has impact results that reflect the reality of South Africa and Canada [44]. On the other hand, studies conducted in the southern region of Brazil [45][46][47] and the state of Minas Gerais [48,49] indicated lower values than the inventory present in the Ecoinvent database (Table 9). Thus, the impact of the dairy products evaluated in this study could be lower than those presented, a point that can be investigated in future studies.…”

Life Cycle Assessment of Dairy Products: A Case Study of a Dairy Factory in Brazil

et al. 2022

The production of dairy products generates several environmental impacts, and life cycle assessment (LCA) is a useful methodology to quantify and understand those impacts. In Brazil, some traditional dairy products have not yet been evaluated using the LCA methodology. Based on this gap, we conducted a cradle-to-gate LCA of six dairy products from a plant in Minas Gerais, Brazil. We also performed two sensitivity analyses. The first analysis was on how the environmental profiles of the products changed depending on how the multifunctional processes were allocated. The second analysis evaluated how these changes in environmental profiles occurred depending on the way that the impacts were allocated to products and by-products (whey and buttermilk) produced within the dairy factory. Among the dairy products studied, the impacts of mozzarella cheese and butter substantially surpassed those of other products; cheese spread and dulce de leche had a similar impact; and yoghurt and milk had the lowest values for the impact categories that were assessed. The inclusion of by-products in the analysis proved to be an effective way to reduce the environmental impacts attributed to the dairy products, especially for cheese and cheese spread, the impact values of which decreased by 56% and 46%, respectively. Additionally, the use of different strategies to deal with the multifunctional processes significantly affected the impact results of the dairy products. The subdivision of processes combined with causal allocation was the best alternative as opposed to the allocation by milk solids. These results could offer a better understanding of the environmental profiles of dairy products from Brazil, especially the traditional products, such as dulce de leche and cheese spread. Other contributions of this study include the proposal of alternatives that could improve the environmental profiles of products (such as the processing of by-products and the questioning of the use of allocation according to milk solids, which have been commonly used in other life cycle assessment studies) and the proposal of a better method for assessing the environmental impacts of dairy products.
