Importance: High-quality evidence on how to improve palliative care in nursing homes is lacking. Objective: To investigate the effect of the Palliative Care for Older People (PACE) Steps to Success Program on resident and staff outcomes. Design, Setting, and Participants: A cluster-randomized clinical trial (2015-2017) in 78 nursing homes in 7 countries comparing PACE Steps to Success Program (intervention) with usual care (control). Randomization was stratified by country and median number of beds in each country in a 1:1 ratio. Interventions: The PACE Steps to Success Program is a multicomponent intervention to integrate basic nonspecialist palliative care in nursing homes. Using a train-the-trainer approach, an external trainer supports staff in nursing homes to introduce a palliative care approach over the course of 1 year following a 6-steps program. The steps are (1) advance care planning with residents and family, (2) assessment, care planning, and review of needs and problems, (3) coordination of care via monthly multidisciplinary review meetings, (4) delivery of high-quality care focusing on pain and depression, (5) care in the last days of life, and (6) care after death. Main Outcomes and Measures: The primary resident outcome was comfort in the last week of life measured after death by staff using the End-of-Life in Dementia Scale Comfort Assessment While Dying (EOLD-CAD; range, 14-42). The primary staff outcome was knowledge of palliative care reported by staff using the Palliative Care Survey (PCS; range, 0-1). Results: Concerning deceased residents, we collected 551 of 610 questionnaires from staff at baseline and 984 of 1178 postintervention in 37 intervention and 36 control homes. Mean (SD) age at time of death ranged between 85.22 (9.13) and 85.91 (8.57) years, and between 60.6% (160/264) and 70.6% (190/269) of residents were women across the different groups. Residents' comfort in the last week of life did not differ between intervention and control groups (baseline-adjusted mean difference, -0.55; 95% CI, -1.71 to 0.61; P =.35). Concerning staff, we collected 2680 of 3638 questionnaires at baseline and 2437 of 3510 postintervention in 37 intervention and 38 control homes. Mean (SD) age of staff ranged between 42.3 (12.1) and 44.1 (11.7) years, and between 87.2% (1092/1253) and 89% (1224/1375) of staff were women across the different groups. Staff in the intervention group had statistically significantly better knowledge of palliative care than staff in the control group, but the clinical difference was minimal (baseline-adjusted mean difference, 0.04; 95% CI, 0.02-0.05; P

Background: Information in society and in health care is currently undergoing a transition from paper to digital formats, and the main source of information will probably be electronic in the future. Objective: To explore patients’ use and perceptions of the patient information leaflet included in the medication package, and their attitude towards a transition to an electronic version. Methods: The data was collected during October to November 2014 among individuals in South-Eastern Sweden, using a questionnaire (n=406, response rate 78%) and interviews (n=15). Results: The questionnaire showed that the majority of the respondents (52%) occasionally read the patient information leaflet, 37% always read it, and 11% never read it. Almost half of the patients (41%) were positive towards reading the patient information leaflet electronically while 32% were hesitant and 26% neutral. A majority of the patients would request to get the patient information leaflet printed at the pharmacy if it was not included in the package. There were differences in attitude related to age and gender. The interviews showed that patients had mixed views on a transition to an electronic patient information leaflet. The patients perceived several positive aspects with an electronic patient information leaflet but were concerned about elderly patients. Conclusion: Although many were positive towards reading the patient information leaflet electronically, the majority prefer the patient information leaflet in paper form. Providing appropriate and useful eHealth services for patients to access the patient information leaflet electronically, along with education, could prepare patients for a transition to electronic patient information leaflet.

- Abstract
Background: ‘PACE Steps to Success’ is a multicomponent training program aiming to integrate generalist and non-disease-specific palliative care in nursing homes. This program did not improve residents’ comfort in the last week of life, but it appeared to improve quality of care and dying in their last month of life. Because this program included only three dementia-specific elements, its effects might differ depending on the presence or stage of dementia. We aimed to investigate whether the program effects differ between residents with advanced, non-advanced, and no dementia. Methods: Pre-planned subgroup analysis of the PACE cluster-randomized controlled trial in 78 nursing homes in seven European countries. Participants included residents who died in the previous 4 months. The nursing home staff or general practitioner assessed the presence of dementia; severity was determined using two highly-discriminatory staff-reported instruments. Using after-death questionnaires, staff assessed comfort in the last week of life (Comfort Assessment in Dying–End-of-Life in Dementia-scale; primary outcome) and quality of care and dying in the last month of life (Quality of Dying in Long-Term Care scale; secondary outcome). Results: At baseline, we included 177 residents with advanced dementia, 126 with non-advanced dementia and 156 without dementia. Post-intervention, respectively in the control and the intervention group, we included 136 and 104 residents with advanced dementia, 167 and 110 with non-advanced dementia and 157 and 137 without dementia. We found no subgroup differences on comfort in the last week of life, comparing advanced versus without dementia (baseline-adjusted mean sub-group difference 2.1; p-value = 0.177), non-advanced versus without dementia (2.7; p = 0.092), and advanced versus non-advanced dementia (− 0.6; p = 0.698); or on quality of care and dying in the last month of life, comparing advanced and without dementia (− 0.6; p = 0.741), non-advanced and

- Abstract
Objective: To examine factors associated with perceived quality of communication with physicians by relatives of dying residents of long-term care facilities (LTCFs). Design: A cross-sectional retrospective study in a representative sample of LTCFs conducted in 2015. In each LTCF, deaths of residents during the 3 months before the researcher's visit were reported. Structured questionnaires were sent to the identified relatives of deceased residents. Settings and participants: A total of 736 relatives of deceased residents in 210 LTCFs (in Belgium, Finland, Italy, the Netherlands, and Poland). Methods: The Family Perception of Physician-Family Communication scale (FPPFC) was used to assess the quality of end-of-life (EOL) communication with physicians as perceived by relatives. We applied multilevel linear regression models to find factors associated with the FPPFC score. Results: The quality of EOL communication with physicians was perceived by relatives as higher when the relative spent more than 14 hours with the resident in the last week of the resident's life (b = 0.205; P = .044), and when the treating physician visited the resident at least 3 times in the last week of the resident's life (b = 0.286; P = .002) or provided the resident with palliative care (b = 0.223; P = .003). Relatives with higher emotional burden perceived the quality of EOL communication with physicians as lower (b = −0.060; P < .001). These results had been adjusted to countries and LTCF types with physicians employed on-site or off-site of the facility. Conclusion: The quality of EOL communication with physicians, as perceived by relatives of dying LTCF residents, is associated with the number of physician visits and amount of time spent by the relative with the resident in the last week of the resident's life, and relatives' emotional burden. Implications: LTCF managers should organize care for dying residents in a way that enables frequent interactions between physicians and relatives

Biomass - Abstract
Bioenergy is a renewable energy source that can replace fossil energy sources in order to decrease greenhouse gas emissions. Assessing the climate impact of bioenergy systems involves methodological choices that may influence the result. Choice of climate metric is one example that has been discussed in several papers recently, and choice of spatial scale is another factor that can impact the results. In this paper, different types of spatial scales (stand, theoretical landscape and real landscape) were used for assessing the time-dependent climate impact of bioenergy from short-rotation coppice willow and stumps harvested from conventional forests in Sweden. The result showed that the spatial scale has importance for the climate impact, especially for long-rotation forestry. However, the climate impact of both types of bioenergy systems was lower than for fossil coal over time, independently of spatial scale used. A landscape perspective was considered to be most relevant from a climate policy perspective., Proceedings of the 25th European Biomass Conference and Exhibition, 12-15 June 2017, Stockholm, Sweden, pp. 1493-1497

- Abstract
Locally produced bioenergy can decrease the dependency on imported fossil fuels in a region, while also being valuable for climate change mitigation. Short-rotation coppice willow is a potentially high-yielding energy crop that can be grown to supply a local energy facility. This study assessed the energy performance and climate impacts when establishing willow on current fallow land in a Swedish region with the purpose of supplying a bio-based combined heat and power plant. Time-dependent life cycle assessment (LCA) was combined with geographic information system (GIS) mapping to include spatial variation in terms of transport distance, initial soil organic carbon content, soil texture and yield. Two climate metrics were used [global warming potential (GWP) and absolute global temperature change potential (AGTP)], and the energy performance was determined by calculating the energy ratio (energy produced per unit of energy used). The results showed that when current fallow land in a Swedish region was used for willow energy, an average energy ratio of 30 MJ MJ-1 (including heat, power and flue gas condensation) was obtained and on average 84.3 Mg carbon per ha was sequestered in the soil during a 100-year time frame (compared with the reference land use). The processes contributing most to the energy use during one willow rotation were the production and application of fertilizers (~40%), followed by harvest (~35%) and transport (~20%). The temperature response after 100 years of willow cultivation was -6·10-16K MJ-1 heat, which is much lower compared with fossil coal and natural gas (70·10-16K MJ-1 heat and 35·10-16 K MJ-1 heat, respectively). The combined GIS and time-dependent LCA approach developed here can be a useful tool in systematic analysis of bioenergy production systems and related land use effects., QC 20170411

Biomass - Abstract
Short rotation coppice willow (SRCW) is a fastgrowing and potentially highyielding energy crop. Replacing fossil fuel with bioenergy has been identified as one strategy to mitigate climate change and decrease the dependency on fossil energy in Sweden. By using life cycle assessment (LCA) methodology, the climate impact of SRCW systems was assessed and compared. The purpose was to evaluate which key factors that influence climate mitigation potential of SRCW grown on historically tilled soils in Sweden. Carbon fluxes between soil, biomass and atmosphere were modelled by using a carbon balance model. The results indicated that SRCW can increase the soil organic carbon content and thereby lead to a climate mitigating effect. The magnitude of this mitigating effect was shown to be dependent on willow yield, where a high yield gave the highest climatic benefits. Opposite, a low yield gave the lowest mitigating effect of the studied scenarios, nevertheless it was still better than the two reference systems, district heating produced from coal or natural gas., Proceedings of the 22nd European Biomass Conference and Exhibition, 23-26 June 2014, Hamburg, Germany, pp. 128-134

- Abstract
Short-rotation coppice willow (SRCW) is a fast-growing and potentially high-yielding energy crop. Transition to bioenergy has been identified in Sweden as one strategy to mitigate climate change and decrease the current dependency on fossil fuel. In this study, life cycle assessment was used to evaluate and compare the climate impacts of SRCW systems, for the purpose of evaluating key factors influencing the climate change mitigation potential of SRCW grown on agricultural land in Sweden. Seven different scenarios were defined and analysed to identify the factors with the most influence on the climate. A carbon balance model was used to model carbon fluxes between soil, biomass and atmosphere under Swedish growing conditions. The results indicated that SRCW can act as a temporary carbon sink and therefore has a mitigating effect on climate change. The most important factor in obtaining a high climate change-mitigating effect was shown to be high yield. Low yield gave the worst mitigating effect of the seven scenarios, but it was still better than the effect of the reference systems, district heating produced from coal or natural gas., QC 20160307

- Abstract
During most of an annual cycle, we studied the temporal variation of total mercury (Hg-T) and methyl mercury (MeHg) in unfiltered and filtered (0.45 mu) peat water from a minerotrophic peat bog in southeastern Sweden. MeHg in bulk water ([MeHgT]) and total Hg in filtered water in discharge water from the peat bog ([Hg-D]) were an order of magnitude higher than in upland runoff water entering the peat bog. At the discharge end, peat-water [Hg-D] and [MeHgD] ranged from 8 to 54 pmol.L-1 and from 1 to 32 pmol.L-1, respectively. Whereas the variation of [MeHgT] was explained by changes in [MeHgD], the variation of inorganic Hg-T [IHgT] = [Hg-T] - [MeHgT] was explained by changes in particle-bound IHg [IHgP] = [IHgT] - [IHgD]. Filterable organic matter and sulfide in the water both correlated poorly with [Hg-D]. Neither did the amount of Hg-T in precipitation and upland runoff water correlate well with the estimated discharge of Hg-D from the peat bog. However, there was a strong correlation between [Hg-D] and [MeHgT] in the peat water (r = 0.96). Furthermore, a significant fraction of Hg-D was MeHg (mean 28%; range 8-60%). These results suggest that methylation increased the mobility of Hg.

- Abstract
Between May and December 1996, monthly samples of surface sediment (0-1 cm), settling matter, and water were taken at a shallow site and a deep site in each of two consecutive Hg-polluted riverine lakes. In the upper lake, the sediment was polluted also with cellulose fiber. Both hypolimnia turned anoxic, but sulfide was detected only in the upper lake. When sulfide appeared, hypolimnetic methyl mercury (MeHg) increased and reached 47 pM (9.4 ng.L-1), whereas MeHg in the sediment below decreased. The increase in hypolimnetic inorganic Hg (IHg = total Hg - MeHg), which reached a peak of 40 pM (8.0 ng.L-1), was slower, possibly because mobilized IHg was methylated. In the lower lake, hypolimnetic MeHg and IHg increased less dramatically during summer stratification, reaching only 5 and 24 pM (1.0 and 4.8 ng.L-1), respectively. There was no detectable concomitant decrease in sediment MeHg. In both lakes, MeHg appeared to increase simultaneously with total Fe and Mn in the hypolimnion, as did IHg in the lower lake. Our observations suggest that the presence of hydrous ferric and manganese oxides decreased the mobility of Hg in both lakes but increased MeHg production in the upper lake.

- Abstract
We deployed CO2 and O2 sensors on the U.S. continental shelf off Cape Hatteras, North Carolina, during late summer 1994. A continuous 32‐d gas record was obtained at 20 m in 25 m of water, below the thermocline for most of the period. Analysis of the correlation between CO2 and O2 indicates that biological and advective processes dominated the gas variability, with small or insignificant fluxes due to air–sea exchange, vertical eddy diffusion, and carbonate dissolution or formation. The observed O2 : CO2 correlation was 1.39, within the range predicted for the photosynthetic quotient. Photosynthesis and respiration appeared to be tightly coupled, resulting in no net community production in these waters during the late summer. It is evident from these results that the combination of mooring‐based CO2 and O2 measurements will be a powerful tool for studying the marine carbon cycle.

- Abstract
The aim of the study was to compare clients' and named home care (HC) workers' perceptions of clients' functional ability (FA) and need for help and to analyse which clientand municipality-related factors are associated with perceptions of client's FA. The total of 686 Finnish HC clients was interviewed in 2001. Further, the questionnaire was sent to 686 HC workers. FA was assessed by activities of daily living (ADL), which included both basic/physical (PADL) and instrumental (IADL) activities. The association between client's FA and municipality-related variables was analysed by using hierarchical logistic regression models. The findings indicated that clients' and HC-workers' perceptions about what the clients were able to do were similar in the PADL functions, but perceptions differed when it comes to the IADL functions for mobility and in climbing stairs. A smaller proportion of clients compared with HC workers assessed themselves to be in need of help in all ADL functions. Use of home help and bathing services increased the probability of belonging to the 'poor' FA class while living alone and small size of municipality decreased the probability. The study indicates that although clients and workers assessed client's FA fairly similarly, there were major differences in perceptions concerning clients' needs for help in ADL functions. Clients' and workers' shared view of need for help forms a basis for high-quality care. Therefore, the perception of both the clients and workers must be taken into account when planning care and services. There was also variation in clients' FA between municipalities, although only the size of municipality had some association with the variation. The probability that clients with a lower FA are cared for in HC is higher if the clients live in large- rather than small-sized municipalities. This may reflect a better mix of services and resources in large-sized municipalities. [ABSTRACT FROM AUTHOR]

POLYCHLORINATED biphenyls - Abstract
The remediation of Lake Jarnsjon in Eman was carried out during the period 1993-1994. PCB-contaminated sediments were dredged, dewatered and disposed of in a landfill. In order to reduce the spreading of suspended solids and PCB to the watercourse, a suction dredger constructed specially for dredging with minimal spread of suspended solids was used. In addition, dredging of the most contaminated part of the lake was carried out within a protective geotextile screen. An extensive environmental monitoring program, running throughout the operation, showed that the spread of suspended solids and PCB during dredging was limited. Monitoring of PCB also showed that the use of geotextile screens considerably reduced the exposure of the river water to PCB. Dewatering was carried out with filter presses and the surplus water was returned to Jarnsjon after cleaning by flocculation, flotation and sedimentation. The landfill was covered with 1.2 m sand and gravel from the site. No external hydraulic barriers were constructed. Instead, the relatively low permeability of the fine-grained and low-contaminated sediments in the topmost meter of the disposedsediments was considered sufficient, also taking into account the low mobility of PCB from the deposited sediments, as measured in the pilot study. Thus, the calculated leakage from the landfill is small compared to the remaining transport of PCB in the river. During the first years of monitoring after construction, only minor leakage has been detected from the landfill. [ABSTRACT FROM AUTHOR]

POLYCHLORINATED biphenyls - Abstract
Remediation of Lake Jarnsjon in Eman (a river in southeastern Sweden) is a part of the Swedish National Site Remediation Action Plan. Jarnsjon contained approx. 400 kg PCB that were slowly leaching out fromthe sediments into Eman. Without remedial action the sediments would have caused problems for many decades. Several investigationsand studies were carried out to determine how and under what limitations cleanup could be performed. An alternative for theremediation was selected that included vacuum dredging within a protective barrier of geotextile screens. Dredged material was to be dewatered and disposed of in a landfill. Remedial activities in Jarnsjon could, however, lead to an additional burden on Eman. Restrictions on and protective measures against such releases during remediation of Jarnsjon were therefore important issues. Dredging was carried out in 1993 and 1994. When dredging was completed, an amount of about 150 000 m
3 had been dredged.According to the follow-up, 394 kg of PCB were removed, which constitutes about 97% of the estimated total amount of PCB in the lake. In the areas included in the remediation operation, about 2.9 kg of PCB were left. The major part of the remaining PCB (7.4 kg) is nowlocated at or near the lakeside, an area which was not included in the remediation operation. In the landfill, heavily contaminated sediments are separated from slightly contaminated sedimentsby a geotextile screen. The reason was to make it possible to localize the heavily contaminated sediments in the future, when remedial techniques have evolved and it may be feasible to carry out more definitive action. This far, the follow-up indicates that thelandfill is behaving satisfactorily. No increase in PCB concentration has been found in groundwater under the landfill, compared to reference levels.

BIOREMEDIATION ,POLYCHLORINATED biphenyls - Abstract
Remediation of 150 000 m(3) of sediment containing 400 kg PCB was performed by suction dredging in a small lake in Sweden in the summers of 1993 and 1994. Upon project completion calculations indicated that97% of the PCB was deposited in a landfill with subsequent low transport to the surroundings, and that 2.9 kg was left in the lake sediment. Concentrations of PCB that were measured weekly in the water leaving the lake were 12 ng/L (geometric mean) during dredging, not exceeding 30 ng/L and not significantly higher than in investigations preceeding the remedial action. The concentration of PCB was negatively correlated to water discharge and positively correlated to water temperature. PCB transport in the river was correlated to water discharge but not to the dredging activity. During dredging of the most contaminated part of the lake, the dredging area was screened off by a geotextile silt curtain that reduced leakage of PCB to the river downstream. [ABSTRACT FROM AUTHOR]

PurposeTo identify transitional palliative care (TPC) interventions for older adults with non-malignant chronic diseases and complex conditions.Design/methodology/approachA systematic review of the literature was conducted. CINAHL, Cochrane Library, Embase and Pubmed databases were searched for studies reporting TPC interventions for older adults, published between 2002 and 2019. The Crowe Critical Appraisal Tool was used for quality appraisal.FindingsA total of six studies were included. Outcomes related to TPC interventions were grouped into three categories: healthcare system-related outcomes (rehospitalisation, length of stay [LOS] and emergency department [ED] visits), patient-related outcomes and family/carer important outcomes. Overall, TPC interventions were associated with lower readmission rates and LOS, improved quality of life and better decision-making concerning hospice care among families. Outcomes for ED visits were unclear.Research limitations/implicationsPositive outcomes related to healthcare services (including readmissions and LOS), patients (quality of life) and families (decision-making) were reported. However, the number of studies supporting the evidence were limited.Originality/valueStudies examining the effectiveness of existing care models to support transitions for those in need of palliative care are limited. This systematic literature review identified and appraised interventions aimed at improving transitions to palliative care in older adults with advanced non-malignant diseases or frailty.

- Abstract
While Electronic Prescription Systems (EPS) adoption varies across EU Member States, there's a lack of comprehensive comparative analysis. Existing studies focus on single EPSs, employ diverse methodologies, and lack up-to-date data. This study fills this gap by providing a comprehensive overview of EPS development, functionalities, and usage statistics in each EU Member State. Most EU Member States widely adopted EPS by 2022, with exceptions including Germany, France, and Luxembourg, where pilot projects or just plans existed at that time. Out of the 27 EPSs, 25 employ a similar design featuring a central server and end-user software or web-based applications. Among these, 22 are structured as single national systems. The fundamental technical solution is remarkably similar across the EU. Despite these similarities, functionalities, authentication methods, prescription validity, and medication coverage differ significantly among EPSs. A multinational team, including co-authors from each EU Member State, collected data using a structured questionnaire. The study underscores the need for standardized methodologies in EPS research and emphasizes the importance of comprehensive comparative analysis to inform healthcare policies and digitalization efforts.

- Abstract
Telemedicine in primary health care is expected to address many of the issues currently challenging service delivery. However, the impact and effect will depend on who will use the new technology., Objective: The objective of the study was to investigate differences between users and non-users of telemedicine integrated into traditional office-based primary health care., Methods: Quantitative registry-based population study in two regions in the southeast part of Sweden ( n = 73,486), comparing users with non-users of telemedicine across the variables sex, age, socioeconomic status (SES), morbidity and health care seeking behaviour (HSB). Two study periods of six months were used (September 2019-February 2020 for Region Östergötland, and September 2021-February 2022 for Region Kalmar County) to collect user data. A reference period of 36 months (September 2016-August 2019) was used, to collect data on HSB., Results: Users were more often women under the age of 60 and had higher morbidity (measured as resource utilisation) than non-users ( p < .001). In contrast, no statistically significant differences were seen between the two groups regarding SES, measured as Care Need Index (CNI). Regarding HSB, a proxy measure (health record entries) showed more entries for users than non-users., Conclusions: Our findings suggest that users are more likely to be women and below the age of 60. Likewise, users also tend to have a greater need for health care services compared to non-users, and they seek health care more often compared to non-users. No differences regarding SES were found.

- Abstract
Background: Deprescribing (i.e., the process of discontinuing an inappropriate medication) requires time, knowledge, and care, but there is a lack of education, support, and guidelines for this important clinical task. A clinical decision support system (CDSS) aims to influence the quality of care by combining structured medical knowledge with patient-specific information to generate recommendations., Objective: The objective was to examine the need to develop a CDSS for drug deprescribing. Furthermore, this study aimed to examine the obstacles to deprescribing and potential users' requirements for a CDSS for deprescribing., Methods: The qualitative design consisted of semistructured interviews with physicians ( n = 10) in Sweden from different disciplines, including geriatrics, primary care and internal medicine. The interviews were conducted using a predefined guide containing multiple questions about any challenges related to deprescribing and the perceived need for a CDSS. A qualitative content analysis was performed to analyse the empirical data., Results: The interviews provided several aspects of the difficulty of deprescribing medicines. The structure and usability of the CDSS knowledge database in clinical practice needs to be ensured from the outset. Physicians needs fast, simple and up-to-date information filtered, summarized and synthesized from reliable sources. The information should preferably be integrated into pre-existing electronic health record., Conclusion: There is a need to develop a CDSS for deprescribing . There is little, if any, guidelines or support for deprescribing, which is regarded as a large obstacle. The current findings contribute to further knowledge regarding the perspective of physicians when deprescribing medication., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2025 The Authors.)

- Abstract
Adverse drug events (ADEs) occur frequently and are a common cause of suffering, hospitalizations, or death, and can be caused by harmful combinations of medications. One method used to prevent ADEs is by using clinical decision support systems (CDSSs). Janusmed Risk Profile is a CDSS evaluating the risk for nine common or serious ADEs resulting from combined pharmacodynamic effects. The aim of this study was to examine the prevalence of potential ADEs identified using CDSS algorithms from Janusmed Risk Profile. This retrospective, cross-sectional study covered the population of a Swedish region ( n = 246,010 inhabitants in year 2020) using data on all medications dispensed and administered. More than 20% of patients had an increased risk of bleeding, constipation, orthostatism, or renal toxicity based on their medications. The proportion of patients with an increased risk varied from 3.5% to almost 30% across the nine categories of ADEs. A higher age was associated with an increased risk of potential ADEs and there were gender differences. A cluster analysis identified groups of patients with an increased risk for several categories of ADEs. This study shows that combinations of medications that could increase the risk of ADEs are common. Future studies should examine how this correlates with observed ADEs.

- Abstract
In response to global challenges in resource supply, many industries are adopting the principles of the Circular Economy (CE) to improve their resource acquisition strategies. This paper introduces an innovative approach to address the environmental impact of waste Glass Fiber Reinforced-Polymer (GFRP) pipes and panels by repurposing them to manufacture structural components for new bicycle and pedestrian bridges. The study covers the entire process, including conceptualization, analysis, design, and testing of a deck system, with a focus on the manufacturing process for a 7-m-long prototype bridge. The study shows promising results in the concept of a sandwich structure utilizing discarded GFRP pipes and panels, which has the flexibility to account for variabilities in dimensions of incoming products while still meeting mechanical requirements. The LCA analysis shows that the transportation of materials is the governing contributing factor. It was concluded that further development of this concept should be accompanied by a business model that considers the importance of the contributions from the whole value chain., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.
