Abstract
Paper aims The paper proposes an enhancement to a focal company in the dairy supply chain, in order to support sustainable performance. Originality The authors conclude that previous life cycle assessment (LCA) studies did not recommend for dairy supply chain or use this approach to assess the environmental impacts in this chain. Research method A cradle-to-gate attributional life cycle assessment (LCA) study performed in a focal company and considering its transport and processing stages, and three scenarios were proposed as suitable. Main findings The impacts derive from energy use and transportation of feedstocks, and the use of cleaning products and certain types of packaging materials. A decrease of 46.5% of the impact in the photochemical oxidant formation category was achieved. Implications for theory and practice The results can identify the different impacts throughout the dairy chain associated with the main product’s life cycle, and the possibility of mitigating them.

Summary
According to the Food and Agriculture Organization of the United Nations (Organisation for Economic Co-operation and Development & Food and Agriculture Organization of the United Nations, 2018), a new trend is coming in dairy demand in developed and developing countries. Per capita consumption of milk solids is projected to grow from 22.2 kg in 2015-17 to 23.1 kg in 2027, compared to an increase from 10.6 kg to 13.5 kg in developing countries This tendency follows from the positive assessment of dairy fat and a change in taste in developed countries, as well as the increasing globalization of diets, which has influenced consumer decisions in developing countries. Increasing milk production, population growth and changing consumer habits are resulting in an increased market volume for dairy products, giving. Modern food production and advanced logistics increase the threats to food safety (Govindan, 2018)
