“…Mouldrý Jr. et al . performed an LCA for the industrial production of potato chips and obtained 2.07 kg CO 2 ‐eq/kg chip, and Nilsson, Sund, and Florén obtained 1.15 kg CO 2 ‐eq/kg potato chip (deep‐fried in palm oil). One manufacturer indicates, on the package (34.5 g), the emissions embedded: 75 g CO 2 ‐eq (=2.17 kg CO 2 ‐eq/kg potato chip) .…”

This study presents a comparative life cycle assessment (LCA) for two homemade processes for obtaining potato chips: hot‐air frying versus conventional stovetop deep frying. LCA evaluates the environmental impacts associated with a product or process by analyzing the product life cycle from the extraction of raw materials from nature to the disposal of the final product. A highly specialized LCA software was employed to obtain the results according to the standardization established by ISO 14040. The results were expressed in kilograms of carbon dioxide equivalent (kg CO2‐eq) using the IPCC 2013 GWP 100y method, due to concerns on climate change and to facilitate comparisons with existing scientific literature. The results presented herein demonstrated that homemade potato chips present lower CO2‐eq emissions when hot‐air frying equipment is utilized, which indicates that this equipment is an appropriate option for Brazilian settings. The consumption of electricity was responsible for an important amount of these emissions. From an environmental point of view, the utilization of refined soybean oil for deep frying potato chips was penalized, with considerably higher emissions than hot‐air frying. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 481–487, 2018

“…On the contrary, when comparing variants of milk, organic milk was a little emission-less burdensome than conventional milk. The latest from animal studies compared the production of eggs [62], where organic eggs produce almost 40% lower emissions than conventional eggs. Results and emission savings are summarized in the Table 2.…”

The chapter focuses on the use of the Life Cycle Assessment method to monitor the emission load of foods from different systems of farming production. The products of the conventional and organic farming production intended for public catering are compared within the SUKI and UMBESA international projects. Conventional farming is mainly characterized by high inputs of mineral fertilizers, chemical pesticides, the use of hormones and stimulants in animal husbandry. It is a system based on the highest possible yields without respecting the natural principles of nature. Conversely, organic farming is a system of production established by the legislation that respects fundamental natural cycles, such as crop rotation, ensures welfare of animals, prohibits the use of fertilizers, pesticides, and other substances of synthetic origin. However, lower yields are a big disadvantage. In the Czech Republic, only about one tenth of the agricultural fund is currently used for organic farming. Arable land constitutes only about 10% of the total area of agricultural land, other areas are mainly grasslands and orchards. The work primarily aims to answer to the question whether the selection of foods may contribute to decrease in greenhouse gas emissions, which is a part of the objectives of many policies. Besides the comparison of agricultural production, processed and unprocessed foods, local and imported foods and fresh and stored foods were compared as well. The Life Cycle Assessment (LCA), which is used to assess environmental impacts of products and services throughout their entire life cycle, was used to quantify the emission load. This method may be briefly characterized as a gathering of all inputs and outputs that take place during the production in the interaction with the environment. These inputs and outputs then also determine the impact on the environment. The LCA consists of four successive and iterative phases: This concerns the definition of objectives and scope, inventory analysis, impact assessment and interpretation of the results. The LCA was originally developed for the assessment of impacts of especially industrial products. Certain methodological problems and deficiency, which bring a level of uncertainty of the results, have been caused by its adaptation to agricultural product assessment, but this method is

“…Example of setting the boundaries of the system within LCA analysis [37] To compare products (systems), it is necessary to define also the functional unit. The functional unit is described as a quantified performance of a product system which serves as a reference unit in a study of life cycle assessment [13].…”
