Summary Life Cycle Assessment (LCA) in Environmental Impact Assessment (EIA): principles and practical implications for industrial projects This article discusses the theoretical and practical aspects of the application of the life cycle assessment (LCA) technique in the environmental impact assessment (EIA) process. LCA enables to consider the environmental impacts of the whole production system, including upstream and downstream processes and to estimate their consequences already at the project planning stage. It was illustrated using the case study of the planned furniture production plant representing the industrial sector. The conventional simplified cradle-to-gate LCA analysis, using SimaPro software and the ReCiPe Endpoint method, was performed. It revealed that unlike the findings of EIA made with the support of traditional methods, not waste, airborne emissions and noise, but the particleboard and the fibreboard used by the planned furniture production plant have the most detrimental impact on the environment in all impact categories. The greatest damage it causes in the areas of protection of resources followed by ecosystems. The research proved high applicability of EIALCA approach for the evaluation of the environmental impacts of planned industrial projects.

Seaborne transport plays an important role in global transportation, and ships’ emissions are worth considering. By applying life cycle assessment method, the environmental impacts of ships could be evaluated. Life cycle assessment is an effective tool as this method provides a holistic perspective of a product or a service in its life cycle. In an attempt to clarify emissions released from the cradle-to-gate life cycle of ships, especially from processes in shipbuilding which were not considered adequately from some previous studies, this study conducts life cycle assessment method to assess the environmental impacts of a Panamax bulk carrier from raw material extraction to shipbuilding phase. In order to clarify life cycle emissions, some helpful mathematical formulas are also established. Ten environmental categories of CML 2001 life cycle impact assessment methodology that are relevant to the marine context are chosen for evaluating the environmental impacts. To obtain emission inventory and impact assessment results, a life cycle assessment software— GaBi—has been used. The results show that material extraction and production phase accounts for more than 85% carbon dioxide, carbon monoxide, nitrous oxide, and methane, while shipbuilding phase is responsible for 99.91% volatile organic compounds, 36.08% non-methane organic compounds, and 26.76% particulate matter emissions. In relation to environmental indicators, material consumption is much more significant than other processes and accounts for more than 86% of values of 10 environmental categories. This study is useful as it provides necessary information for life cycle assessment in the shipping industry in the future.

Food Production System

Traditional Cambodian food has higher nutrient balances and is environmentally sustainable compared to conventional diets. However, there is a lack of knowledge and evidence on nutrient intake and the environmental greenness of traditional food at different age distributions. The relationship between nutritional intake and environmental impact can be evaluated using carbon dioxide (CO2) emissions from agricultural production based on life cycle assessment (LCA). The objective of this study was to estimate the CO2 equivalent (eq) emissions from the traditional Cambodian diet using LCA, starting at each agricultural production phase. A one-year food consumption scenario with the traditional diet was established. Five breakfast (BF1–5) and seven lunch and dinner (LD1–7) food sets were consumed at the same rate and compared using LCA. The results showed that BF1 and LD2 had the lowest and highest emissions (0.3 Mt CO2 eq/yr and 1.2 Mt CO2 eq/yr, respectively). The food calories, minerals, and vitamins met the recommended dietary allowance. The country’s existing food production system generates CO2 emissions of 9.7 Mt CO2 eq/yr, with the proposed system reducing these by 28.9% to 6.9 Mt CO2 eq/yr. The change in each food item could decrease emissions depending on the type and quantity of the food set, especially meat and milk consumption.

This study analyzed the characteristics of the environmental impacts of apartment buildings, a typical housing type in South Korea, as part of a research project supporting the streamlined life cycle assessment (S-LCA) of buildings within the G-SEED (Green Standard for Energy and Environmental Design) framework. Three recently built apartment building complexes were chosen as study objects for the quantitative evaluation of the buildings in terms of their embodied environmental impacts (global warming potential, acidification potential, eutrophication potential, ozone layer depletion potential, photochemical oxidant creation potential, and abiotic depletion potential), using the LCA approach. Additionally, we analyzed the emission trends according to the cut-off criteria of the six environmental impact categories by performing an S-LCA with cut-off criteria 90–99% of the cumulative weight percentile. Consequently, we were able to present the cut-off criterion best suited for S-LCA and analyze the effect of the cut-off criteria on the environmental impact analysis results. A comprehensive environmental impact analysis of the characteristics of the six environmental impact categories revealed that the error rate was below 5% when the cut-off criterion of 97.5% of the cumulative weight percentile was applied, thus verifying its validity as the optimal cut-off criterion for S-LCA.

The Impact

With the development of additive manufacturing technology, 3D bone tissue engineering scaffolds have evolved. Bone tissue engineering is one of the techniques for repairing bone abnormalities caused by a variety of circumstances, such as injuries or the need to support damaged sections. Many bits of research have gone towards developing 3D bone tissue engineering scaffolds all across the world. The assessment of the environmental impact, on the other hand, has received less attention. As a result, the focus of this study is on developing a life cycle assessment (LCA) model for 3D bone tissue engineering scaffolds and evaluating potential environmental impacts. One of the methodologies to evaluating a complete environmental impact assessment is life cycle assessment (LCA). The cradle-to-grave method will be used in this study, and GaBi software was used to create the analysis for this study. Previous research on 3D bone tissue engineering fabrication employing poly(ethylene glycol) diacrylate (PEGDA) soaked in dimethyl sulfoxide (DMSO), and diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide (TPO) as a photoinitiator will be reviewed. Meanwhile, digital light processing (DLP) 3D printing is employed as the production technique. The GaBi program and the LCA model developed to highlight the potential environmental impact. This study shows how the input and output of LCA of 3D bone tissue engineering scaffolds might contribute to environmental issues such as air, freshwater, saltwater, and industrial soil emissions. The emission contributing to potential environmental impacts comes from life cycle input, electricity and transportation consumption, manufacturing process, and material resources. The results from this research can be used as an indicator for the researcher to take the impact of the development of 3D bone tissue engineering on the environment seriously.
