Opis:
A review of the available literature concerning environmental impact assessment for industrial symbiosis has been carried out. The authors have recommended the use of life cycle assessment method for this purpose. It was stated that so far few studies presenting LCA results of industrial symbiosis have been published. Among the factors which contribute to the success of symbiotic exchange, the close location of collaborating companies has been often mentioned. This paper presents LCA results concerning the environmental impact of symbiotic gypsum transmission. Concepts of relative distance and critical distance for the case of industrial symbiosis were proposed and defined. Significant difference between critical distance obtained for particular endpoints were observed (3.5- 564 km). Application of Life Cycle Sustainability Triangle enabled the estimation of critical distance taking into account various impact categories. A sensitivity analysis indicated the relationship between critical distance and the means of transport which reflected the effect of scale. The critical distance determined for heavy trucks was 3.2 - 3.9 times longer than in case of lighter vehicles.

Opis:
The aim of the study was to determine the environmental potential impact of the palm shell biofuel production process using life cycle assessment (LCA) through gate to gate approach. The environmental impact of each scenario was assessed using ISO 14040 (2006), which includes goal and scope definition, life cycle inventory (LCI), life cycle impact assessment (LCIA) and interpretation. The simapro v.9 software with ecoinvent 3.5 database was utilized to assess the environmental effect. The impact analysis method used is Impact 2002+. Functional units were used to show environmental references in damage assessment and characterization, such as energy use and global warming potential. The results show that the environmental impact evaluation obtained through LCA for the entire biofuel production process stated that the thermal cracking stage resulted in the highest global warming impact, compared to other processes, which was 118.374 kg CO2 eq. For the categories of human health, ecosystem quality, and climate change, each has a value of 0.0001 DALY; 15.708 PDF•m2•yr; and 335.233 kg CO2 eq where this value is the total damage assessment of the entire biofuel production process. From the results of the analysis by utilizing the networking graph on the simapro application, it can be seen that the environmental hotspot of the thermal cracking process of biofuel production is due to the use of electricity from the State Electricity Company (PLN) and the release of chemical substances from the process. To improve the environmental performance of biofuel production process, additional development steps are required to increase biofuel yield, purification efficiency of biofuel to obtain pure liquid fuel, and the use of renewable energy sources to generate electricity. Additionally, more particular data would be required for a more precise LCA study result.

Opis:
Power-to-liquid (PtL) fuels are a promising technology and alternative to biofuels and conventional fuels. In this work, the environmental impact of PtL was investigated using life cycle assessment (LCA) in order to see how the energy source used in producing the PtL affects the environmental impacts of the fuel. The electrolysis cell used was solid oxide electrolysis cell, and the pathway of CO2 provision was biomass power plant. Four scenarios of energy sources were compared; the first scenario involved the electricity from German grid and heat from chemical industry, the second one was the electricity from Saudi Arabia grid and heat from chemical industry, the third one concerned the electricity from wind turbine and heat from evacuated tube collector, and the fourth scenario was the electricity from photovoltaic and heat from evacuated tube collector. The result of the life cycle assessment showed that the PtL fuels have environmental benefits over the fossil reference only in the third and fourth scenarios where renewable electricity was used.

Opis:
With new sulphur oxides emission limits carried out in 2020, multiple desulphurisation methods have been proposed. The main desulphurisation scrubber systems were chosen and investigated using life cycle assessment. The whole system life is divided into the construction and operational phases. Three different systems classified by desulphurisers, namely, seawater, NaOH, and Mg-based systems, were modelled in GaBi software. Moreover, environmental, economic and energy aspects (3E model) were introduced for further analysis. Through this study, some conclusions have been drawn. As for the environmental aspect, the seawater system has the most pleasing performance since the primary emissions come from 1.24E+03 kg CO2 and 1.48E+01 kg chloride. The NaOH system causes 1000 times more emissions than the seawater. The Mg-based system has less pollution than the NaOH system, with 5.86E+06kg CO2 and 3.86E+03 kg chloride. The economic aspect is divided into capital expenditure (CapEx) and operational expenditure (OpEx) to estimate disbursement. The seawater system also has the most favourable cost appearance, which takes 1.7 million dollars without extra desulphuriser expenses, based on 10MW engine flue gas treatment. The next is the Mg-based system, which cost 2 million dollars in CapEx and $ 1200/year in OpEx for the desulphuriser. NaOH uses about 2.5 million dollars for construction and $ 30000/year in desulphuriser. As for the energy aspect, the seawater and Mg-based systems use less non-renewable energy than the NaOH system in the construction phase. In conclusion, the seawater system shows the best performance and could be an alternative in SOx control technologies. This study sheds light on the comprehensive evaluation of marine environmental protection technologies for further optimisation.

Opis:
The life cycle of furniture products has been decreased in the last years as a consequence of the continuous improvement of people’s housing conditions. This behavior increases the waste amount in an urban area. The focus of this study was developing a Life Cycle Assessment (LCA) (cradle-to-grave) of a new countertop product. Two scenarios for countertop waste management were proposed, one considering landfilling and another considering recycling. The functional unit chosen was 1 m2 of finished panel (countertop) and the boundary system involved the study of raw materials, product packaging, the panel production process, the installation process, the panel use, and its end of life. The chosen method for impact assessment was EPD (2018) available in the SimaPro PhD software. The results showed that recycling has a positive effect on the environmental impacts, with the variation ranging from 0.3% on Abiotic Depletion (FF) to 15.9% on Eutrophication. A comparison between the product studied and products with similar functions was also conducted and although this product was not the worst performer, it has a lot of room for improvement.

Opis:
Post-harvest handling / processing of fishery commodities requires large amounts of water and energy to overcome their perishable properties. Water is needed as raw/auxiliary material and to ensure that the production process and its environment meet the sanitary and hygiene principles. Meanwhile, large amount of energy is required for the transportation of raw materials and products, cold chain system during the process and operations of processing machines. They contribute towards the environmental impact of fish processing. This study used life cycle assessment to estimate the potential environmental impact of small scale mackerel fish processing. The results showed that the fish processing has contributed to 0.079 kg SO2 eq acidification potential, 9.66 kg CO2 eq climate changGWP 100, 0.02 kg PO4 eq Eutrophication-generic, 0.17 kg 1.4 DCB eq human toxicity-HTP inf, and 0.0015 kg ethylene eq photochemical oxidation-high NOx. Wastewater treatment implementation simulation showed elimination of direct emissions that contribute to eutrophication and increasing the potential of other process associated with energy consumption.

Opis:
The building objects show a wide variety. Among them, we can distinguish buildings and various building constructions. In addition to the fact that they are of various sizes, they perform different functions, while their purpose and use generates various problems, they can be made using various materials, different technologies and construction solutions. Therefore, the decision on which solutions to apply may be difficult to make. In this situation, it is good to develop several alternative solutions for their comprehensive comparison. In addition, the existing regulations that originate in the EU directives, in many cases impose the obligation to develop several variants of future investments and analyze them taking into account many factors. In the EU recommendations, the analysis related to the impact of construction investments on the environment is of highest importance. The ISO 14040–1404X regulations created and introduced by the European Union are the most important tool for a global assessment of the environmental impact of a product, facility and service. They relate to the environmental impact assessment of the entire Life Cycle Assessment (LCA), and their assumption is to identify and minimize any environmental impacts that may arise from the production, use and disposal of the product. Research should include specific stages according to the LCA evaluation system: determination of the purpose and scope of the assessment, inventory of input and output data and the impact assessment. The following research methods were used: source materials analysis, library query, advanced data collection methods through online surveys, LCA assessment, multicriterial methods. The research conducted by the author showed that the analysis involving selected problems related to the object-environment interaction is dominant. However, in practice it is difficult to find the analyses covering the entire lifecycle of an object in accordance with the LCA procedure and examples of comparison of specific design solutions within the variant assessment procedure taking into account the LCA procedure. The aim of the article is to show how such procedure can look while comparing the exemplary variants of a construction project. The article presents an example and diagrams of conduct covering the whole life cycle of an object, and the analysis is based on specific examples.

The management of smallholder coffee plantations in Bengkulu Province has not yet conducted according to good agricultural practices. As a result, the productivity and quality of green beans produced are also low. The efforts to improve this condition need to be made in order to maintain the economic, social, and environmental sustainability of this agribusiness. The present study aimed at identifying the life cycle of the coffee agroindustry in supporting sustainable agriculture using the Life Cycle Assessment (LCA) method. The results of the study revealed that the energy input from the use of fertilizers, herbicides, manpower, and fossil fuel was 4349.08 MJ/ha. The energy output from the green beans and coffee husks was 9763.39 MJ/ha and 13524.21 MJ/ha, respectively, so the efficiency based on the input-output ratio was 5.35. The emission values to the global warming potential, acidification, and eutrophication were 109.43 kg eqCO2 , 345.70 g SO2 eq/ha/year, and 28.54 g PO4 3-eq/ha/year, respectively. The coffee agribusiness in Kepahiang Regency is categorized as organic. The coffee agribusiness was economically feasible with a Net B/C of 2.87, but the land ownership which was 1.45 ha/household and the present agribusiness conditions indicate a low sustainability rate.

Opis:
Life Cycle Assessment, included in company environmental management methods, has particular importance in marketing management. Analysis of dangers to the environment through tools such as the LCA method allows for comparisons of alternative company management strategies. LCA is characterised as a technique for environmental management that enables environmental impact assessment of the product, process, industry, and even the comprehensive economic sector. LCA also influences decisions regarding environmental policy modification, but most importantly, it influences a company's marketing activities. The LCA technique is applied the world over with great effectiveness in studying specific phases of a product's life cycles – from 'birth to death'; however, Poland's experience in this domain constitutes continuously developing research areas. The experience of foreign research centres confirms the possibility of applying LCA techniques in supporting environmental risk assessment of innovative technologies where LCA is used to study the environmental impact of a new generation product, i.e. flocculants from polymer wastes. This article presents the results of a study of the effectiveness of applying a new generation of polyelectrolyte (gained from polystyrene waste) in treating industrial wastewater and the LCA environmental impact assessment, which was carried out using SimaPro software. Based on the analysis of the results of the application of sodium salts of sulfone derivatives of polystyrene in the treatment of mine water, it was found that these products significantly reduced the pollution indicators of mine water from KWK1. Accordingly, they provided the basis for the development of technical-scale technology.

Opis:
The following article is an analysis of designed processes of the life cycle of the most popular fuel for Diesel engines: diesel oil. This fuel is produced from petroleum, which is a non-renewable source of energy. Analysis was carried out with the assumptions of Life Cycle Assessment, which is a tool to test the environmental impact of the product. The life cycle of diesel was divided into five unit processes: petroleum extraction, transport of petroleum to the refinery, refining petroleum to diesel, transport of diesel to the recipient and utilization of delivered fuel by transport company. For every process the energy consumption and emission of carbon monoxide, nitrogen oxides and sulphursulphur oxides was calculated, with assumption of probable data, that could occur in real processes. The analysis has shown, that the process of refining petroleum is highly pollution-intensive. Also the combustion of diesel generates a significant amount of pollutants’ emission, which is why it is necessary to develop technologies that could contribute to the reduction of emission.

Opis:
Produkcja energii w Polsce w głównej mierze oparta jest na węgielu kamiennym i brunatnym, co powoduje znaczne obciążenia dla środowiska. Dlatego istotne jest poszukiwanie alternatywnych sposobów jej wytwarzania. W artykule dokonano identyfikacji i oceny problemów środowiskowych związanych z technologią naziemnego zgazowania węgla brunatnego z wykorzystaniem techniki oceny cyklu życia. Przedstawiono metodę analizy cyklu życia ILCD Midpoint (The International Reference Life Cycle Data System) rekomendowaną przez Komisję Europejską do stosowania jako reprezentatywną dla warunków europejskich. Metoda ILCD została wykorzystana zarówno do oceny problemów środowiskowych technologii zgazowania węgla brunatnego, jak i analizy porównawczej produkcji energii elektrycznej opartej na technologii zgazowania wę- gla oraz technologii spalania węgla. Wykazano, iż technologia zgazowania węgla w największym stopniu wpływa na emisję gazów cieplarnianych oraz powoduje działanie toksyczne dla ludzi. Określono również determinanty wpływu na środowisko, do których zaliczono emisję ditlenku wę- gla oraz wydobycie węgla brunatnego. Wykazano, że technologia zgazowania powoduje mniejsze obciążenia dla środowiska w porównaniu do technologii spalania węgla, szczególnie w kategorii wpływu – działanie toksyczne dla ludzi, działanie inne niż rakotwórcze.
Energy production in Poland is based primarily on hard coal and lignite, which creates a considerable environmental burden. It is therefore important to look for alternative methods of energy generation. The article contains the identification and evaluation of environmental problems related to the technology of ground coal gasification using the life cycle assessment technique. The ILCD Midpoint method (The International Reference Life Cycle Data System) of life-cycle analysis, recommended by the European Commission as representative for European conditions, is presented. The ILCD method has been used both to evaluate environmental problems of the technology of lignite gasification and to make a comparative analysis of electricity production based on the technology of coal gasification and coal combustion. It has been shown that the technology of coal gasification has the most significant impact on the emission of greenhouse gases and produces toxic effects for humans. Determinants of the impact on the environment, including emissions of carbon dioxide and lignite mining, have been identified. It has been demonstrated that the gasification technology causes less environmental burden compared to the coal combustion technology, particularly in the impact category – human toxicity, non-cancer effects.

Opis:
The article proposes the manner of determining ecological benefits, which result from thermo insulation of the external walls of the building. In order to assign environment load the technique of life cycle assessment LCA was used, including the division into three damage categories: human health, ecosystem quality and raw materials. The production of thermo insulating materials causes the increase of the environment load, but in the thermal phase of the building usage the negative impact on the environment is reduced due to the reduction of energy demand necessary to heat. A few dozen of thermo insulation variants were examined, depending on the kind of wall, heat source and thermo insulating material. For all cases the analyzed investment turned out to be cost effective in terms of ecological aspects. In each damage category the reduction of the environment load was obtained. The ecological payback period was obtained within 0–5 years.

Opis:
This paper examines the application of life cycle assessment (LCA) as an approach to foster the product and process oriented eco- innovation of enterprises, using the fruit and vegetable processing plant as an example. LCA, which is traditionally used to assess the impacts of a single product system on the environment, was applied in the enterprise context. This was made possible by forming an indicator describing the environmental profile of an enterprise, which is calculated by the sum of the multiplication of the environmental impact assessment (LCIA) results for individual unit processes within a particular impact category and their weights reflecting the structure of production in an enterprise. In order to distinguish and indicate the direction in which an enterprise should undertake its eco-innovative actions (implementing eco-innovations within the product or production process) the LCIA results are presented individually for products and production processes. The research was conducted in full compliance with the LCA methodology. LCA proved that the analysed enterprise has the largest negative impacts on the environment in the following impact categories: marine eco-toxicity, freshwater eco-toxicity, freshwater eutrophication, human toxicity and natural land transformation. They result primarily from the consumption of thermal and electric energy in the production processes. Therefore, to improve energy efficiency, the enterprise should take eco-innovative actions in the processes applied.
