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.

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.

Indonesia is the country with the greatest potential for sago in the world. This research is intended to determine the carbon footprint of sago starch produced from a semi-mechanical process. The calculation was carried out using the LCA approach with the system boundary of cradle to gate. The process steps were carried out in a combination of manual work and diesel-driven engines. The inventory data on material, energy input flows and emissions were obtained from 3 samples of typical medium-scale semi-mechanical sago mills. It was found that the carbon footprint of the sago produced from semi-mechanical processes was 37.9±0.6 kgCO2 eq per 1 ton of dried sago starch. Further analysis shows that 62% of the carbon footprint comes from the extraction stage and 38% from the transportation. It can be estimated that the amount of greenhouse gas emissions from the semi-mechanical sago starch production in Indonesia for 2018 reached around 2,617,639 kg CO2 eq.

The research results presented in this article are an answer to the controversial theses questioning the validity of traditional recycling methods. The voices of scientific circles which have appeared recently indicate that irrational waste management and energy-intensive recycling of selected products bring more harm than benefits to the environment. This paper is devoted to the assessment of selected environmental effects of traditional recycling processes for container glass. The environmental impact of collection, segregation, transport and remelting of glass waste was analysed using the LCA (Life Cycle Assessment) method and available databases. The environmental impact of the processes described was assessed in terms of selected criteria: climate change, energy depletion, air emissions, toxicity and depletion of natural resources. Two methods were used for the calculations: the method of the Institute of Environmental Engineering of Leiden University–CML and the Ecological Scarcity Method (ESM). The calculations were carried out for an exemplary city located in eastern Poland. The study showed that, compared with purely natural glass production, the production of recyclates was more favourable in terms of all the above-mentioned factors. Additional calculations made it possible to estimate the waste transport distance, for which the environmental impact of transporting recyclate to the glassworks made the glass recycling process by re-melting less favourable than the production of packaging from natural resources.

he European Union places great emphasis on the use of renewable energy sources in the energy industries. The share of bio-components in liquid fuels consumption is expected to reach 10% by the end of 2020. A consequence of this regulation is the increased cropping area of rapeseed in Poland. The aim of the study was to quantify the environmental impact associated with winter rape production along the life cycle stages. The method used to calculate the overall environmental profile of rapeseed was the Life Cycle Assessment (LCA). Analysis was based on the case study of two large-area farms in the Wielkopolska region carried out in the years 2011–2013. Our study showed that fertilizer operation was the largest contributor to the environmental impact categories, representing almost 99 percent of the acidification potential and 77 percent of the global warming potential. Among the components of fertiliz- ing operations, field application of nitrogen fertilizers generated the highest load of greenhouse gas emissions. It is concluded that the data obtained characterizes the con- ventional type of rapeseed production in the Wielkopolska region and can be used as source material for extending the LCA to the rapeseed processing industry which receive the material from the local suppliers.

Opis:
Pesticides are at risk due to their toxic properties in humans as well as impact on the environment and ecosystems. Indonesia has 1,336 formulations and 402 pesticide ingredients registered to control pests in various commodity fields. The negative effects of synthetic chemical pesticides are resistance, resurgence, second pest blasting, and environmental degradation. Pesticide residues on the soil and agricultural products can cause bioaccumulation and biomagnification processes. The biomagnification process can cause exposure to pesticides that enter the human body to a greater degree than the residues found in the environment. Therefore, it is necessary to research the life cycle analysis of exposure and pesticide residues in agricultural environments. This study is an observational study with a cross-sectional design. The sample in this study was 120 respondents. This research was conducted in the Wanasari subdistrict, Brebes regency. Wanasari subdistrict is the largest shallot-producing centre in Brebes regency (26%). The shallot harvest area in Wanasari district is 6,598 ha. The life cycle analysis (LCA) results of shallot farming include five stages: soil maturation, planting seedlings, fertilizing, applying pesticides, and harvesting. The emissions in shallot farming activities come from diesel fuel, pesticides, and NPK fertilizers. Chlorpyrifos pesticide residues were found with an average level of 0.6451 ppm in 9 villages in Wanasari district.

The study examined mixtures obtained from ready pyrotechnic articles available on the market in Poland. Samples were taken from various products with different performance characteristics, i.e. pyrotechnic batteries, firecrackers, volcanoes, as well as smoke candles, rockets (including rocket engines), and cold fires. These are the product categories most frequently used by users. The research allowed to determine gaseous combustion products and showed their life cycle in the environment. A comparative analysis of selected pyrotechnic mixtures was carried out in terms of their impact on the climate change of gas products. Using the ICT-Thermodynamic Code program, gaseous combustion products were estimated and the life cycle was analysed using the SimaPro program. Determining the impact on the environment (upon the basis of Ecoindicator 99) allowed to know the scale of the problem and set the direction of development of the pyrotechnic industry, so that importers could compete not only with the price and quality of products offered, but also tried to reduce the potential impact on the environment.

Opis:
The production of cocoa beans in Indonesia into chocolate and other cocoa-derived products produces emissions that pollute the environment. This research aimed to calculate the carbon footprint of the cocoa agroindustry using the Life Cycle Assessment approach in Lampung, Indonesia. The LCA under study is within the scope of Cradle to Grave, starting from nurseries_cocoa plantations_dry cocoa beans_chocolate production_retail, and consumers with emission function units per 1 kg of product. The method refers to the ISO 14040:2006 life cycle assessment standard, with the stages of determining objectives and scope, inventory analysis, impact assessment, and interpretation of recommendations. Primary data was analyzed using Simapro 9.4.0.2 Software. Secondary data was collected through a literature study. Data analysis shows the highest environmental impact after normalization resulting from four activities: packaging, transportation from industry to marketing office, and transportation from marketing office to retail. The highest environmental impact is generated by industrial activities, with a total emission of 2.57E-10 per kg of dark chocolate. In this study, GWP 100a emissions from cocoa agroforestry and agroindustry activities within the scope of the Cradle to Grave study were 7.31E+01 kg CO2-eq per kg dark chocolate. In addition, selecting the type of packaging is an indicator that must be considered. Using a combination of aluminum foil, paper, and cardboard as packaging causes the second highest emission in the packaging sub-process after transportation from industry to marketing office in industrial activities. It is the 4th highest of all activities. One of the reasons for the high emissions produced in the final product or cocoa consumed by consumers is no longer in doubt. On the basis of normalization activities, the highest environmental impacts were generated by industrial activities, with a total emission of 2.57E-10. The use of packaging in packaging and fuel activities in transportation from industry to marketing office activities, industrial activities also use quite a large amount of electrical energy, namely 421.91 kWh. Recommendations for improvement can be identified to reduce the GHG impact and increase energy efficiency. Energy-saving sustainablemethods constitute a challenge for the cocoa agroindustry because they positively impact the reduction of the global warming potential.
