Using sustainability indicators for analysis of sustainable consumption and production in the food supply chain

Abstract

Delivery of food products is one of the critical points in the manufacturing of products, especially for perishable products. In addition, it is necessary to consider the delivery schedule and additional environmental load due to the need to maintain the storage temperature conditions. It has been proven that the main factors of sustainability related to local products are determined by the desire of consumers to support the local producer, the sale of higher-quality products of local production, and the efficiency of logistics management and sale of goods. Methods to analyze the sustainability of food product transportation are considered. It is emphasized that very few studies have been conducted on analyzing the logistics of the delivery of dairy raw materials and products in countries with a weak economy, especially for enterprises of local importance whose vehicle fleet is represented by outdated equipment. That is why the study of the sustainability of logistics delivery chains was conducted based on the data of two dairy enterprises. The work presents in mathematical terms an integrated model for calculating the sustainability of logistics chains, which consists of four groups of criteria: resources, climate, economic efficiency, and impact on society. The company was evaluated according to the specified criteria by a group of independent experts in dairy technology using the Delphi method to ensure the objectivity of the obtained data. The calculation of fuel costs and CO2 emissions into the atmosphere per kilogram of food products in the transportation logistics chain was carried out. This approach will ensure the objectivity of assessing the negative impact on the environment because of the use of petroleum products, the increase of greenhouse gases, and air pollution in general. The concepts of "local food" and "food miles" are tools of the protectionist policy of restoring local agriculture and alternative sources of food production. The results obtained in the work confirm the need to use individual criteria in LCA for an objective assessment of the sustainability of logistics transportation and its impact on the environment. Keywords: "food mile", food products, environment, sustainability indicators, temperature regimes.
