Applying social life cycle assessment in the informal recycling sector: Understanding challenges and limitations

The transition towards Circular Economy (CE) is a promising approach to sustainable development that may cause significant social impacts. Despite the benefits of CE initiatives, key players such as informal recyclers face serious social issues such as poverty, lack of social security, and discrimination. Although evaluating social impacts remains a considerable challenge, Social Life Cycle Assessment (SLCA) is recognized as a suitable methodology with a life cycle perspective. While most SLCA experiences are conducted in the formal sector, it is important to consider the informal sector, which plays a crucial role in developing countries. This article presents an analysis of SLCA studies in informal recycling settings in order to identify the challenges and adjustments required for informal settings. The analysis is based on a literature review and a documentary review of a pilot application of SLCA in the informal recycling system in Cuenca, Ecuador. The results show that SLCA requires adaptation to be applied in informal settings. There are particular challenges in delineating boundaries due to the fuzzy nature and variability of informal activities. Tasks such as establishing specific indicators, developing reference scales and data collection, require careful planning and active stakeholder participation. For instance, indicators regarding Fair Salary or Working hours were adapted based on best practices. Furthermore, tasks such as verifying and disseminating results should be included in interpretation phases to generate long-term impacts and influence behaviors. The study underscores SLCA's multidimensional view but highlights the need for further standardization and adaptation for informal sectors.

Using the Product Social Impact Life Cycle Assessment (PSILCA) database for product comparison: Confetti case study

Purpose

Social Life Cycle Assessment (S-LCA) is a methodology that can help companies administer their supply chain and promote both social responsibility and sustainability through the assessment of both positive and negative social and socio-economic aspects of products during their entire life cycle. Here, a case study was performed to test an S-LCA database as a comparative assessment tool of two products, i.e. the traditional almond sugared confetti and Tenerelli sugared almonds, made by the same company.

Methods

The S-LCA case study was carried out by using the Product Social Impact Life Cycle Assessment (PSILCA) database, for the two products on openLCA software.

Results and discussion

The risk assessment helped to identify the most affected impact categories and which product influences the most on them as well as the categories on which the foreground processes have the greatest impact. For both the analysed products, the category "Contribution of the sector to economic development" is marginally affected. Overall, the production of Confetti entails higher medium risk hours regarding some categories (e.g. "Public sector corruption", "Promoting social responsibility", "Migration flows"), whilst for others, it is the Tenerelli that affect the most (e.g. "Biomass consumption", "Trade unionism"), depending on the different inputs used. Finally, the results are not very influenced by foreground processes, and the social risks are therefore related to upstream processes for both products.

Conclusions

The comparison can become more useful for products of the same or similar functions and the same audience but of different inputs and therefore different supply chains. Indeed, it could be useful for decision-making with the aim of selecting between various possible options the one that entails lower social risks.

Social impact and social performance of paddy rice production in Iran and Malaysia

PURPOSE

Sustainable agri-food production is incredibly important for society. Despite Iran and Malaysia being one of the highest production countries for paddy rice, there is no study on the social life cycle assessment (S-LCA) for rice production for both countries in the literature. The lack of data and complexity of social issue are the challenges of conducting the S-LCA study. This study compared the social impacts from the related stakeholders in the life cycle of paddy rice production between Malaysia and Iran.

METHODS

This study applied S-LCA based on UNEP (UNEP/SETAC Life Cycle Initiative, 2020) as an evaluation technique to investigate social issues and social performance of paddy rice production in Malaysia and Iran. This research included workers, local communities, and farmers as the stakeholders. The inventory data were collected by using questionnaires. The subcategories for evaluation were adapted from UNEP 2020 guideline. The items in the questionnaire were separately validated by experts in Malaysia and Iran, and the reliability was done by conducting pilot studies in Malaysia and Iran. The questionnaires were distributed by multistage sampling method. The following four steps were conducted following the ISO14040 framework: (1) goal and scope definition, (2) social life cycle inventory analysis (S-LCI), (3) social life cycle impact assessment (S-LCIA), and (4) interpretation.

RESULTS AND DISCUSSION

The result showed that the social performance of workers and farmers in Malaysia was better than Iran because of low cost with high yield for farmers, contributing to increased income. Rice cultivation in Iran for local community did not show good performance regarding health and safety because of burning of rice residue. Around 62% of local Iranian people reported air pollution from rice residue burning. However, the overall social performance for local community was not different in Iran and Malaysia, showing good performances with respect to job opportunity. Sexual harassment was identified as one of the negative social issues in Iran with the score of 60%, including unwanted sexual attention. Moreover, the farmers showed poor performance in Iran, resulting from low satisfactory from income, and low yield and high cost of paddy production in Iran.

CONCLUSION

The key investigation from this research revealed that social performance of crop production in different geographical areas could show different results. The key finding from this study reported that modern agriculture could increase social and economic performance by reducing the production cost, and increasing productivity and social performance in terms of satisfactory from income for farmers. The result of this study can be used for policy makers to improve social performance by using modern agriculture.

Applying social life cycle assessment to evaluate the use phase of mobility services: a case study in Berlin

PURPOSE

The main purpose of this S-LCA case study is to analyse social impacts of the use phase of mobility services is a holistic way, taking into account positive as well as negative impacts. The use phase plays an important role for the assessment of services, which is why this study exclusively focuses on the use phase assessment. That way, this study aims to contribute to answer the question whether mobility services can improve quality of life in cities.

METHODS

For the analysis, seven different mobility options were chosen in the city of Berlin, Germany, including free-floating car sharing, e-scooter sharing, S-Bahn, subway, tram, bus and the car in private ownership. For the analysis, five stakeholder groups that are outlined in the S-LCA Guidelines (UNEP 2020) were taken into account: Local Community, Consumer, Worker, Value Chain Actors and Society. For a detailed analysis of all relevant aspects, 37 indicators were analysed, out of which 23 are quantitative and 14 are qualitative. For data collection, several different data sources were used, including publicly available data e.g. from statistics as well as own data from interviews.

RESULTS AND DISCUSSION

For comparability, all results are displayed on a 5-point scale from - 2 to + 2, in line with the Handbook (Goedkoop et al. 2018) and the S-LCA Guidelines (UNEP 2020). For some indicators, the results of the case study are as expected, for example regarding impacts on air quality. For other indicators, however, the results are specific for the analysed mobility services in Berlin and therefore give new insights and reveal new aspects, as for example in the case of job creation for the local community. The main challenge of this S-LCA case study was data availability and data quality, which is why assumptions and simplifications had to be made, especially regarding space occupancy and the allocation of common infrastructure.

CONCLUSIONS

This S-LCA case study provides a holistic assessment of the use phase of mobility services, taking into account five stakeholder categories and their respective social impacts. The study illustrates specific results for the city of Berlin, showing positive as well as negative social impacts of mobility services and outlines a procedure for further studies. That way, this case study contributes to answer the overlying question whether mobility services can improve quality of life in cities.

Unveiling the social performance of selected agri-food chains in Costa Rica: the case of green coffee, raw milk and leafy vegetables

PURPOSE

Several frameworks coincide in the importance of addressing social impacts to ensure sustainability. However, the agri-food sector, regarded as key in sustainable production, still neglects to identify potential social impacts when applying life cycle approaches. This work contributes to understanding the social performance of three agricultural products from a Latin American and Caribbean developing country as Costa Rica while recognising the challenges of Social-Life Cycle Assessment (S-LCA) application in this context.

METHODS

S-LCA represents a powerful technique to evaluate the potential social impacts of a product. Three case studies were analysed through S-LCA, using the subcategory assessment method (SAM) to characterise the social impacts and detect hotspots in the production of green coffee, raw milk and leafy vegetables. Primary data was collected through questionnaires to relevant informants and observations. In addition to secondary information, these data and information were used to assess eight impact subcategories for the farmer and worker stakeholder groups and nine subcategories for the local community.

RESULTS AND DISCUSSION

The main results suggest that the Costa Rican institutional and market frameworks provide an enabling environment for a generally positive social performance in the studied cases. The assessed stakeholders can fulfil basic needs through access to inputs and services and achieve fair-trading conditions. Child labour, forced labour and evidence of environmental or health risks for the surrounding communities were absent. Important efforts to address the delocalisation, migration and child labour were observed, suggesting the potential development of social handprints in further studies. However, the farm production phase, related to farmers and workers, entails hotspots regarding social security and women's empowerment. Moreover, farmers appear as the most vulnerable group because of their overall social performance.

CONCLUSIONS

S-LCA helped identify relevant areas of intervention in the context of these particular case studies; however, further research and capacity building are recommended to tackle the detected challenges, both in the agri-food chains and in the use of S-LCA. Furthermore, these findings can aid in future decision and policy-making to improve and safeguard the positive social performance observed in the studied products.
