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:: 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 NO_x. 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.

Opis:: 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:: 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:: 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.

Opis:: 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.

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.

Opis:: There has been a notable increase in both consumer knowledge and awareness regarding the ecological benefits of green products and services. Manufacturers now pay more attention to green, environmentally friendly production processes. Two significant tools that can facilitate such a goal are life cycle assessment (LCA) and ecological footprint (EF). This study aimed to analyse and determine the damage to the environment, focusing on the canned fruit and vegetable processing. Canned sweet corn (340 g) was selected for the case study. All inputs and outputs associated with the product system boundary were collected through field surveys. The acquired inventory was then analysed and evaluated using both LCA and EF methodology. The results were converted into an area of biologically productive land and presented as global hectares (gha). The ecological footprint of one can of sweet corn was calculated as 6.51E-04 gha. The three factors with the highest impact on ecological footprint value were the corn kernels used in the process, the packaging and steam, equivalent to 2.93E-04 gha, 1.19E-04 gha and 1.17E-04 gha respectively. To promote the sustainable development, the company should develop new technology or utilize better management techniques to reduce the ecological footprint of canned food production.

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.

Opis:: This paper is devoted to the topic of obtaining substitutes for natural aggregates in the city mining system. An article draws attention to the adverse effects of natural aggregate mining on the environment and presents its alternative based on processing waste mineral materials into aggregate form. Referring to the examples presented in the literature, technical possibilities of producing recycled aggregates from waste concrete, ceramic and glass materials were indicated. The system of collecting waste directly from potential users was also presented and the adaptation processes which waste must undergo were described. The research part of the study consisted of analyses of the environmental impact of the processes of obtaining natural aggregates and production of their substitutes from waste in the city mining system. The LCA (life cycle assessment) method was used to carry out the analyses. Using the available databases, calculations of the environmental impact of both processes were performed. The comparison of the obtained results proved that despite the unfavourable additional environmental effects caused by the adaptation processes required for waste, the environmental impact of the rational production of aggregates from recyclates is favourable, and such activities should be recommended for implementation in the industry.
