The ecological transition is a process the building industry is bound to undertake. This study aimed to develop new bio-based building partition typologies and to determine if they are suitable ecological alternatives to the conventional non-renewable ones used today. This work started with the development of a bio-based epoxy composite board and a waste-based sheep wool acoustic absorbent. Six different partition typologies combining conventional and bio-based materials were analyzed. A drywall partition composed of gypsum plasterboard and mineral wool was used as the baseline. First, a cradle-to-gate life cycle assessment was performed to compare their environmental impacts. Secondly, a mathematical simulation was performed to evaluate their airborne acoustic insulation. The LCA results show a 50% decrease in the amount of CO2 equivalent emitted when replacing plasterboard with bio-composite boards. The bio-composites lower the overall environmental impact by 40%. In the case of the acoustic absorbents, replacing the mineral wool with cellulose or sheep wool decreases the carbon emissions and the overall environmental impact of the partition from 4% and 6%, respectively. However, while the bio-based acoustic absorbents used offer good acoustic results, the bio-composites have a lower airborne acoustic insulation than conventional gypsum plasterboard.

Abstract An approach for integrating life-cycle assessment (LCA) into the eco-design of lighting products was developed, and LCAs of five lighting products that are currently on the market were then carried out using this approach. Based on the results of these LCAs, the sustainability requests for lighting products were derived and embedded into the product design specification (PDS), thus ensuring that any product developed according to the PDS would have the desired eco-design features. A new sustainable lighting product was then designed according to the PDS and manufactured, after which the new product underwent LCA. Upon comparing the results of the LCA of the new product with the LCA results for the existing lighting products, the newly designed product was found to provide better environmental performance than the existing products (a 27–58% reduction in environmental impact).

AbstractOver the years considerable research has been conducted on masonry mortars regarding their compatibility with under restoration structures. The environmental dimension of these materials may sometimes be a prohibitive factor in the selection of these materials. Life Cycle Assessment (LCA) is a tool that can be used to assess the environmental impact of the materials. LCA can be a very useful tool in the decision making for the selection of appropriate restoration structural material. In this work, a comparison between traditional type of mortars and modern ones (cement-based) is attempted. Two mortars of traditional type are investigated: with aerial lime binder, with aerial lime and artificial pozzolanic additive and one with cement binder. The LCA results indicate that the traditional types of mortars are more sustainable compared to cementbased mortars. For the impact assessment, the method used is Eco-indicator 95

Abstract Tofu is one of the processed soybean foods that are very popular with Indonesian society. Despite the popularity of Tofu, Tofu production in Indonesia is generally small and medium, reaching 500 kg per day, as in the tofu factory in Semanan, West Jakarta. The purpose of this study is to analyze the environmental impact of tofu production in West Jakarta. The life cycle assessment (LCA) approach was used to achieve this goal with SimaPro software for impact calculations. This research applies the LCA cradle to gate, which consists of soybean cultivation, transportation, and tofu production processes. The environmental impacts of tofu production analyzed in this study include global warming, ozone depletion, acidification, and eutrophication. The impact analysis showed that the acquisition of soybeans, which consisted of soybean cultivation and transportation, had the most significant environmental impact with a global warming potential value of 0.882 kg CO2 eq out of a total of 0.978 CO2 eq for the whole process.

Raw materials for buildings and construction account for more than 35% of global primary energy use and nearly 40% of energy-related CO2 emissions. The Intergovernmental Panel on Climate Change (IPCC) emphasized the drastic reduction in GHG emissions and thus, wood products with very low or negative carbon footprint materials can play an important role. In this study, a cradle-to-grave life cycle assessment (LCA) approach was followed to quantify the environmental impacts of laminated strand lumber (LSL). The inventory data represented North American LSL production in terms of input materials, including wood and resin, electricity and fuel use, and production facility emissions for the 2019 production year. The contribution of cradle-to-gate life cycle stages was substantial (>70%) towards the total (cradle-to-grave) environmental impacts of LSL. The cradle-to-gate LCA results per m³ LSL were estimated to be 275 kg CO2 eq global warming, 39.5 kg O3eq smog formation, 1.7 kg SO2 eq acidification, 0.2 kg N eq eutrophication, and 598 MJ fossil fuel depletion. Resin production as a part of resource extraction contributed 124 kg CO2 eq (45%). The most relevant unit processes in their decreasing contribution to their cradle-to-grave GW impacts were resource extraction, end-of-life (EoL), transportation (resources and product), and LSL manufacturing. Results of sensitivity analysis showed that the use of adhesive, consumption of electricity, and transport distance had the greatest influences on the LCA results. Considering the whole life cycle of the LSL, the final product stored 1,010 kg CO2 eq/m³ of LSL, roughly two times more greenhouse gas emissions over than what was released (493 kg CO2 eq/m³ of LSL) from cradle-to-grave. Overall, LSL has a negative GW impact and acts as a carbon sink if used in the construction sector. The study results are intended to be important for future studies, including waste disposal and recycling strategies to optimize environmental trade-offs.

Abstract This study performs a life cycle assessment (LCA) of five new family houses in Eastern Slovakia to compare them in terms of the materials and technologies used. The main goal of the analysis is to investigate and highlight the expectable reduction rate of environmental impact resulting from using green materials and technologies. Their environmental impact is determined by using eToolLCD software. The life cycle impact assessment (LCIA) categories of global warming, ozone depletion, acidification, eutrophication and photochemical ozone creation potential are determined within the cradle-to-grave boundary. The examined family houses are built of conventional materials such as aerated concrete blocks, expanded polystyrene (EPS) for thermal insulation and roofing mineral wool, as well as natural materials such as clay, straw, wood, cellulose and vegetation for the roofs. Family houses built of natural materials are characterized by negative emissions of CO2eq in the product phase. Results show that especially the product phase contributes greatly to all environmental impact categories for houses built of conventional materials, such as aerated concrete blocks, mineral wool for thermal insulation, reinforcement concrete and ceramic or concrete tiles.

The paper analyses the detailed structure of the environmental footprint of technologies used for potato production on plantations covering areas of various sizes. The research was conducted for potato cultivation in Lesser Poland. In order to determine the environmental impact with the LCA method, the SimaPro application was used, ver. 8.1.0.60. The “cradle-to-gate” approach was adopted, taking into account the type of technological practices, as well as machines, duration of their operation, number of seed potatoes, fertilisers, pesticides, used fuel and water. The final results were referred to the area of cultivation (1 ha). It was, for instance, found that one of the greatest impact factors of potato cultivation affecting the natural environment is the use of seed potatoes and relatively high consumption of diesel.

AbstractThe main objective of this paper is to compare the environmental impact caused by two different types of water boiling processes. The aim was achieved thanks to product life cycle assessment (LCA) conducted for stovetop and electric kettles. A literature review was carried out. A research model was worked out on the basis of data available in literature as well as additional experiments. In order to have a better opportunity to compare LCA results with reviewed literature, eco-indicator 99 assessment method was chosen. The functional unit included production, usage and waste disposal of each product (according to from cradle to grave approach) where the main function is boiling 3360 l of water during 4-year period of time. A very detailed life cycle inventory was carried out. The mass of components was determined with accuracy of three decimal places (0.001 g). The majority of environmental impact is caused by electricity or natural gas consumption during usage stage: 92% in case of the electric and kettle and 99% in case of stovetop one. Assembly stage contributed in 7% and 0.8% respectively. Uncertainty and sensitivity analyses took into consideration various waste scenario patterns as well as demand for transport. Environmental impact turned out to be strongly sensitive to a chosen pattern of energy delivery (electricity mix) which determined final comparison results. Basing on LCA results, some improvements of products were suggested. The boiling time optimization was pointed out for electric kettle's efficiency improvement. Obtained results can be used by manufacturers in order to improve their eco-effectiveness. Moreover, conclusions following the research part can influence the future choices of home appliances users.
