The restrictions imposed on the use of formaldehyde in wood panel adhesives have been the driving force behind the development of formaldehyde-free resins for the manufacture of wood products. Considering as a boundary condition the idea that the use of fossil-based raw materials should be replaced by biological options, there is growing interest in the environmental assessment of different alternatives for soy-based adhesives, as possible options to replace commonly used synthetic resins. This report includes the environmental profiles of soy-based adhesives taking into account the life cycle assessment (LCA) methodology. In addition, in order to increase their potential to replace synthetic resins, a sensitivity analysis of the main contributors to environmental damage was performed, thus giving an open guide for further research and improvement. This study aims to provide innovative alternatives and new trends in the field of environmentally friendly bio-adhesives for the wood panel industry.

This paper presents the eco-efficiency assessment of the pulp and paper industry in Myanmar by using the key indicators such as raw material consumption, energy consumption, total waste output, water consumption, and CO 2 emissions. The study was carried out by using quantitative methods for data analysis of the production, consumptions and emissions from fiscal year 2001–2005. The results revealed that the level of economic and environmental performance using the eco-efficiency ratio for each fiscal year has decreased since year 2002, and factory tried to increase the level of eco-efficiency again in year 2005. There was the positive aspect that factory could optimize the waste utilization by transferring lime mud to the cement factory in the last two fiscal years. This analysis showed the root causes that led to the losses of material, energy and water consumption and discussed how to conserve those utilities.

The Himalayan foothills of West Bengal are a part of the great Eastern Himalaya, which is by locational virtue a recognized flood-prone area. The area is also well known for frequent and heavy rain storms and climate-induced catastrophic events, such as flash floods due to the unprecedented rains in the Bhutan Himalaya. Therefore, climate-induced disasters like floods have been the prime reasons for rural vulnerabilities. Therefore, the primary aim of the present study is to find out whether there are any differences between levels of vulnerability amidst agriculture-dependent villages and forest resource-dependent villages in the same flood-prone area or not. In addition, the study will also examine how the agriculture-dependent villages are different from forest resource-dependent villages in terms of climate vulnerability and vice versa. The climate change vulnerability index has been applied, and a total of 100 households have been surveyed covering seven dimensions of vulnerability. The exposure score was found to be the highest in Raja Bhatkhawa (0.41) followed by Nathuar Char (0.30) and Bhelakoba (0.27). No significant differences were found in terms of climatic exposure except in Mendabari. Further, it has been observed that the resilience factors in households like education, workforce opportunities, health, and institutional accessibility are highly uneven, which has been creating hinders to the adaptive capacity. In the villages where overall vulnerability to climate change was found to be high, the adaptive capacity was found to be low. Simultaneously, in those villages, the sensitivity was found to be high. It has been found that the location of the villages plays an important role when it comes to vulnerability because the forest villages are relatively more vulnerable than the agricultural villages. However, the riverside location of Nathuar Char has made this village highly vulnerable; and the people of Nathuar Char have been living with floods, and they are trying to adapt with climate-induced floods. Finally, it has been observed that vulnerability is context dependent (i.e. based on land resources, accessibility to basic infrastructure, water and sanitation facilities, and awareness to disasters) and varies from household to household.

Achieving net-zero greenhouse gas emissions by 2050 under the European Green Deal requires the full mobilisation of industry, especially energy-intensive sectors such as cement. This study provides an accurate quantification of the environmental performance of Ordinary Portland cement produced in mainland Portugal using industrial data and a cradle-to-gate life-cycle model compliant with EN 15804:2012+A2:2019. The results show that clinker is the main contributor and that the principal hotspots are associated with thermal and electrical energy supply and the calcination reaction. External factors such as the electricity generation mix materially influence results, so these processes should be accurately described and representative of the geographical boundaries associated with plant operation. Climate change is the most relevant impact category, and the carbon footprint is 733 kg CO2 per tonne of cement, with 97% attributable to the identified hotspots. The choice of impact assessment methodology is crucial in life-cycle assessment, and EN 15804:2012+A2:2019 is not compatible with the earlier A1 revision, which affects comparability of Environmental Product Declarations. Overall, the study enhances the measurement and monitoring of sustainability within the cement sector by providing an explicit industry-wide environmental profile with clear system boundaries and hotspot resolution, enabling targeted mitigation. It also clarifies the methodological implications of Environmental Product Declarations, helping to avoid biased comparisons and supporting procurement, disclosure and policy tracking towards sectoral carbon neutrality.

In recent years, sport entities have begun to prioritise environmental sustainability (ES) initiatives in their business strategies with the aim of minimising their environmental impact and engaging stakeholders within the ES movement. There has been minimal academic consideration of the ES movement in professional sport, particularly outside of North America and Europe. The aim of the present study is to provide an overview of the type and profile of ES initiatives being undertaken and communicated to stakeholders in the Asia-Pacific region by the industry bodies. Further, the study offers a conceptual model of the global-, country-, industry- and organisational-level forces impacting these sporting organisations' ES practices. Various communication mediums of 114 professional sport teams from seven countries—Australia, India, New Zealand, Japan, China, Taiwan and Korea— were evaluated using content analysis. The results reveal low communication of ES practices by professional sport teams in the Asia-Pacific region compared to North America. Extended findings on the existing global profile of ES engagement provide a descriptive understanding of the ES movement in the Asia-Pacific region, and contribute to the identification of possible antecedents and correlatives to be evaluated in future research.

Wood is one of the most fully renewable building materials, so wood instead of non-renewable materials produced from organic energy sources significantly reduces the environmental impact. Construction products can be replenished at the end of their working life and their elements and components deconstructed in a closed-loop manner to act as a material for potential construction. Materials passports (MPs) are instruments for incorporating circular economy principles (CEP) into structures. Material passports (MPs) consider all the building’s life cycle (BLC) steps to ensure that it can be reused and transformed several times. The number of reuse times and the operating life of the commodity greatly influence the environmental effects incorporated. For a new generation of buildings, the developing of an elegant kinetic wooden façade has become a necessity. It represents a multidisciplinary region with different climatic, fiscal, constructional materials, equipment, and programs, and ecology-influencing design processes and decisions. Based on an overview of the material’s environmental profile (MEP) and material passport (MP) definition in the design phase, this article attempts to establish and formulate an analytical analysis of the wood selection process used to produce a kinetic façade. The paper will analyze the importance of environmentally sustainable construction and a harmonious architectural environment to reduce harmful human intervention on the environment. It will examine the use of wooden panels on buildings’ façades as one solution to building impact on the environment. It will show the features of the formation of the wooden exterior of the building. It will also examine modern architecture that enters into a dialogue with the environment, giving unique flexibility to adapt a building. The study finds that new buildings can be easily created today. The concept of building materials passport and the environmental selection of the kinetic wooden façade can be incorporated into the building design process. This will improve the economic and environmental impact of the building on human life.

Purpose The purpose of this work is to quantify the environmental impact of the sugarcane industry in Tucumán (Argentina) through the life cycle analysis (LCA). The distinctive feature is the consideration of different technology levels (TLs) in the agricultural stage: high (HTL), medium (MTL), and low (LTL). Methods The scope of the study covers the agricultural and industrial stages through a “from cradle to gate” approach (from sugarcane cultivation until production of finished products: sugar and alcohol). The system is divided into Agriculture , Sugar Factory , and Distillery . Data used for the inventory are mainly provided by local experts, sugarcane growers, and processing companies. The characteristics of each TL are taken from a regional classification. For the impact assessment, the CML 2001 model (nine impact categories) is used. Results and discussion Regardless of the TL, in most of the impact categories, an important contribution attributable to the use of synthetic agrochemicals is evident. As for the comparison among TLs, the ethanol produced with HTL has less impact values than the ones produced with MTL and LTL in seven categories. These results can be mainly explained by the better cultural yields obtained with HTL, and to the fact that sugarcane is not burnt before harvesting in HTL as it is in MTL and LTL. Conclusions This study explores the implications of using different TLs for the agricultural tasks on the sugarcane supply chain in Tucumán, which is characterized by a vertically nonintegrated productive scheme. If practices associated to HTL are implemented, a reduction of the environmental impact is observed in most categories. It is necessary to compare these results with economic and social implications to ensure sustainability of the sugarcane value chain.

In the current context of the European Environmental legislation and standards, the automotive sector is expected to continuously improve the vehicles life cycle with solutions able to minimise emissions of greenhouse gases and other negative effects on the environment and on human health. The vehicle painting process has been identified to be responsible of significant potential impacts, but recent primary inventory data and impact results are currently scarcely available in the literature. The novelty of this paper is the provision of a comprehensive life cycle inventory and life cycle assessment (LCA) of a painting process, with reference to a large and highly automated plant located in Turin (Italy). To achieve these goals, the highly recognised methodology of LCA has been followed, as indicated in ISO 14040-44. A detailed inventory is disclosed (both as input/output table and ILCD file) for the four main phases of the painting process (electrodeposition, primer application, top coat application and final drying and revision). Impact results on the categories of climate change, acidification, terrestrial eutrophication and photochemical ozone creation potential are quantified as well. These latter show that the major hot points are the high-energy consumption (specifically, the integrated provision of technological heating and chilled water is responsible of almost half of the total emissions of greenhouse gases), the direct emission of volatile organic compounds into air (for a total of 7.44 kg/car) and the waste production and treatment [giving a significant contribution to the impact categories of ozone depletion (99%), freshwater eutrophication (66%) and freshwater ecotoxicity potential (60%)]. This study contributes to increase the pool of publicly available life cycle data for specific applications in the automotive sector. In addition, the easy replicability and adaptation of the provided inventory is expected to boost enterprises to increase their overall sustainability. Finally, this study provides data and tools for the development of further research in alternative painting technologies.Graphic abstract

In the development of packaging products, the considerations are not limited to the food shelf-life, safety, and practicality, but also environmental sustainability. This paper reports a life cycle assessment (LCA) analysis of a proposed natural fiber-reinforced biopolymer composite takeout food container. The study focuses on the damage assessment of the whole product system, including disposal scenarios of the thermoformed sugar palm fiber (SPF)-reinforced sago starch composite takeout food container. The analysis performed was to anticipate the environmental impact of the cradle-to-grave approach. The results exhibited the total human health damage of 2.63 × 10−5 DALY and ecosystem damage of 9.46 × 10−8 species.year per kg of containers. The main contributor was the carbon dioxide emission from fossil fuel combustion for energy generation that contributed to climate change and caused human health and the ecosystem damages with low-level metrics of 1.3 × 10−5 DALY and 7.39 × 10−8 species.yr per kg of containers, respectively. The most contributed substances in the ‘Particulate matter formation’ impact categories that caused respiratory diseases were from air/nitrogen oxides, air/particulates, <2.5 µm, and air/sulphur dioxide with the metrics of 2.93 × 10−6 DALY, 2.75 × 10−6 DALY, and 1.9 × 10−6 DALY per kg containers, correspondingly. Whereas, for the ‘Agricultural land occupation’, which contributed to ecosystem damage, almost the total contributions came from raw/occupation, forest, intensive with the metric of 1.93 × 10−9 species.yr per kg of containers. Nevertheless, from the results, all impact categories impacted below than 0.0001 DALY for the Human Health damage category and below 0.00001 species.yr for the ecosystem damage category. These results would provide important insights to companies and manufacturers in commercializing the fully biobased takeout food containers.

In order to evaluate the environmental performance generated by a “semi-technified” pig farm, as well as the comparison of different pig production scenarios, pig feed and animal production subsystems were evaluated considering both: (a) origin of feed ingredients and (b) variations in pig weight. Life cycle assessment methodology was used to evaluate the environmental performance, establishing 1 market pig as the functional unit (FU). Three ingredient origin distances (400, 950, and 1800 km) and three slaughter weights (110, 100, and 90 kg) were considered for the simulation analysis and comparison. The feed production subsystem was the main generator of environmental impacts, mainly caused by the cultivation of sorghum and the production of fat. The origin of the inputs represented the main increase in environmental impact for the feed production subsystem, mainly in the Fossil Depletion category, with a fivefold increase by acquiring inputs from 900 km and a ninefold increase at a distance of 1800 km. Producing lighter pigs resulted in the best environmental alternative, given the resultant 11% reduction in environmental impact.
