Application of a methodology for the social life cycle assessment of recycling systems in low income countries: three Peruvian case studies

Purpose

In a previous phase of this work, a methodology oriented towards social Life Cycle Assessment (sLCA) was developed to assess the social impact of formalised recycling systems in low income countries. To support this, a literature review of social impact assessment methodologies was carried out incorporating the social issues of both the informal and the implemented, formal recycling approaches. The goal of this study is to determine the feasibility of applying this methodology by assessing the current social impacts of three Peruvian recycling systems based on two formalisation approaches. A further goal is to identify and measure the social impacts of the formalisation procedures, thereby confirming or rebutting the expectations and forecasts of organisations (NGOs, Local Authorities, Ministries & Business) involved in the implementation.

Methods

The methodology developed was applied to three Peruvian recycling systems which had been formalised using two different approaches. One approach utilizes cooperation with recyclers’ associations and the second one, operated by the municipality uses formalised recyclers as employees. Interviews were conducted with local recycling system stakeholders in order to collect data to assess fulfilment of the social criteria. Three impact categories and 9 subcategories were analysed using 26 indicators. To transform the qualitative information into numerical values, a score system 1 or 0 for the fulfilment or non-fulfilment of social criteria was applied. After obtaining the indicators’ average scores, further characterisation by social impact subcategory was effected. The final scores for the subcategories show the fulfilment or otherwise of all social criteria related to the subcategory.

Results and discussion

The assessment substantiates similar negative impacts of both formalisation approaches for the social subcategories discrimination, recognised employment relationships and fulfilment of social benefit, physical working conditions and education. The formalisation based on cooperation with recyclers’ associations reveals a positive social impact for freedom of association and collective bargaining, psychological working conditions and social acceptance whereas the method operated by the municipality scores better for working time and minimum, fair incomes. Regarding the methodology, no difficulties were detected in applying the indicators.

Conclusions

It can be concluded that although sLCA was originally used to analyse products and production processes, it is feasible to adapt it for the social assessment of recycling systems based on formalisation of the informal sector in low income countries. A comparison of current social impacts between different formalisation approaches using this methodology is also viable. A further conclusion is that it is feasible to measure the social impacts of formalisation approaches using the selected indicators and characterisation procedure. Social issues such as anti-discrimination policies, employment terms, payment of social benefits, preventive policies, occupational and health training and adult education can be improved following the evaluation.     

Towards social life cycle assessment: a quantitative product social impact assessment

Purpose

The main goal of this paper is to present the feasibility of the quantitative method presented in the Product Social Impact Assessment (PSIA) handbook throughout a case study. The case study was developed to assess the social impacts of a tire throughout its entire life cycle. We carried out this case study in the context of the Roundtable for the Product Social Metrics project in which 13 companies develop two methodologies, a qualitative and a quantitative one, for assessing the social impact of product life cycle.

Methods

The quantitative methodology implemented for assessing the social impact of a Run On Flat tire mounted in a BMW 3 series consists of 26 indicators split in three groups. Each group represents a stakeholder group. Primary data of the quantitative indicators were collected along the product life cycle of the Run On Flat by involving the companies, which owned the main steps of the product life cycle. Throughout this case study, an ideal/worst-case scenario was defined for the distance-to-target approach to compare the social performances of more products when they are available.

Results and discussion

The implementation of the PSIA quantitative method to a Run On Flat illustrated the necessity to have a referencing step in order to interpret the results. This is particularly important when the results are used to support decision-making process in which no experts are involved. It frequently happens in a big company where the management level has to take often decisions on different topics. Reference values were defined using ideal or worst-case-target scenarios (Fontes et al. 2014). For those topics where it was possible, an ideal/ethical scenario was defined, e.g., 0 h of child labor per product. In other cases, we defined a worst-case scenario, e.g., 0 training hours per product. It was then possible to interpret the results using a distance-to-target approach. A matrix was developed in the case study for identifying in which step of the product life cycle data is not available; that means we need more transparency in the supply chain.

Conclusions

Each value of the matrix can be compared to the ideal/worst scenario to compare the step to each other and to identify along the product life cycle which step and the relative supplier that needs further measures to improve the product performance. Furthermore, a quantitative value for each indicator related to the product life cycle is calculated and compared with the ideal/worst scenario. The case study on Run On Flat represents the first implementation of the quantitative method of PSIA.

     

Product social impact assessment

Purpose

Whereas the business evolution of environmental sustainability metrics has advanced significantly over the past decade, social sustainability at product level is still relatively immature. Research continues to support the front runners on organisational sustainability, while workable solutions at product level have not yet been addressed sufficiently. Triggered by this imbalance, a group of experts from large companies decided to join forces, initiating the Roundtable for Product Social Metrics.

Methods

Starting in early 2013, this group of companies aimed to (i) consolidate principles for product social sustainability assessment and harmonise approaches, (ii) align with other global initiatives and share with other companies and (iii) develop solutions for cross-cutting implementation issues. In order to be able to produce a comprehensive method for social impact assessment that provides enough flexibility for individual requirements, the Roundtable developed a method based on the approaches of the participant companies and external references such as the UNEP/SETAC Guidelines for Social Life-Cycle Assessment of Products and corporate level standards. Guiding principles were defined for the development of the method.

Results and discussion

The results of the first two phases of the Roundtable for Product Social Metrics are documented in a handbook, which proposes a practical method for organisations to assess the social impacts of a product or a service along its life cycle. The handbook outlines an aligned method for social impact assessment at a product level offering two approaches: quantitative and scale based. The method was developed to allow reasoned assessment of overall performance by including social topics and performance indicators that reflect positive and negative impacts of the product on three stakeholder groups: workers, consumers and local communities. Nineteen social topics are proposed, together with their individual performance indicators, including detailed definitions. Application examples and recommendations for the communication of results are also included in the handbook.

Conclusions

The method can be applied in numerous scenarios, from understanding improvement opportunities and steering product development in different stages, to providing support for decision making and external communications. However, the method still has further potential for improvement, inter alia that the proposed indicators are not fully applicable to small farmers, SMEs and the self-employed, as well as that the indicators are mainly at inventory level. Furthermore, the proposed method is strongly dependent on the availability of data.

     

Biomass assessment in third world villages via a systems methodology

Using a systems analysis methodology, the potential of indigenously produced biomass to enhance the development of a Third World rural community can be gauged through time. An integrated system of physical and biosolar technologies, allied to improvements in traditional agriculture, is demonstrated to increase output and decrease the need for expensive energy intensive imports such as diesel for irrigation and chemical fertilisers for maximising crop productivity.Under the conditions simulated for an existing Indian village, food consumption can increase by around 200%, indigenous energy production by 85% and overall solar energy capture by just over 150% - all within 12 years. Even with a population growth rate of 2% per annum, the scenario proposed is robust enough to maintain improved living standards well into the next century. Should such a strategy for decentralised development be extensively adopted then it could benefit a significant proportion of the people currently living in the rural areas of the Third World.

Allocation in recycling systems

‘Design for Recycling’ and dematerialization by enhancing the durability of products are major aspects of the quest for sustainable products. This article presents an LCA-based model for the integrated analyses of the product chain, its recycling systems, and its waste treatment systems at the ‘End of Life’ stage. The model is an extension of the EVR (Eco-costs/Value Ratio) model which has been published in this journal (Vogtländer et al. 2001), but can also be applied to other life cycle interpretation models, since the model as such is not restricted to the use of the eco-costs as a single indicator. The model has been developed to evaluate the design alternatives of complex products like buildings and cars. These products comprise several subsystems, each with its own special solution at the End of Life stage: Extending of the product life, object renovation, re-use of components, re-use of materials, useful application of waste materials, immobilization with and without useful applications, incineration with and without energy recovery, land fill. Since complex product systems always comprise a combination of these design alternatives, a methodology is given to calculate and allocate the eco-costs of the total system in order to select the best solution for sustainability. The methodology is characterized by:

1. A main allocation model of the recycling flow based on physical relationships,
2. a strict separation of the market value, the costs and the ecocosts in the system,
3. a main allocation model for extension of lifetime based on ‘depreciation of eco-costs’, parallel to economic depreciation.

     

A process-orientated design and performance assessment methodology for passive mine water treatment systems

The aim of this paper is the development of a methodology for assessing the iron removal efficiency of passive mine water treatment settling lagoons and reed beds. Previous work in the design and sizing of coal mine drainage lagoons and wetlands has focussed on the use of standard hydraulic residence times or using the 10 g m⁻² d⁻¹ metric, these criteria have been applied without regard to the fundamental physical and chemical processes controlling iron removal in the system, namely the pH dependent rates of Fe(II) oxidation and physical settling of the particulate Fe(III). In this study field water quality data have been collected from lagoons and reed beds. These data are examined alongside data from the UK Coal Authority database and combined with simple mathematical formulations to provide a framework through which to understand passive treatment schemes from a process-orientated perspective. It is demonstrated that for the sites studied reed beds are more efficient for iron removal. This paper recommends that judgements of iron removal performance should be based on a derived treatment efficiency index (?) and that the modelling approach espoused in this paper should be used when designing passive mine water treatment schemes.     

IMPACT 2002+: A new life cycle impact assessment methodology

The new IMPACT 2002+ life cycle impact assessment methodology proposes a feasible implementation of a combined midpoint/damage approach, linking all types of life cycle inventory results (elementary flows and other interventions) via 14 midpoint categories to four damage categories. For IMPACT 2002+, new concepts and methods have been developed, especially for the comparative assessment of human toxicity and ecotoxicity. Human Damage Factors are calculated for carcinogens and non-carcinogens, employing intake fractions, best estimates of dose-response slope factors, as well as severities. The transfer of contaminants into the human food is no more based on consumption surveys, but accounts for agricultural and livestock production levels. Indoor and outdoor air emissions can be compared and the intermittent character of rainfall is considered. Both human toxicity and ecotoxicity effect factors are based on mean responses rather than on conservative assumptions. Other midpoint categories are adapted from existing characterizing methods (Eco-indicator 99 and CML 2002). All midpoint scores are expressed in units of a reference substance and related to the four damage categories human health, ecosystem quality, climate change, and resources. Normalization can be performed either at midpoint or at damage level. The IMPACT 2002+ method presently provides characterization factors for almost 1500 different LCI-results, which can be downloaded at http://www.epfl.ch/impact     

Drought impact assessment on rural livelihood systems in Iran

The present study aimed to analyze the effects of drought on rural livelihood systems in Iran with an emphasis on the mediator role of livelihood assets in relationship between drought and livelihood outcomes. The relationships between these concepts were explored through the lens of sustainable livelihoods approach. A conceptual model was developed based on the literature review and was evaluated using cross-sectional data based on 11 years average of each variable from 2002 to the end of 2012. Regarding research objectives, a documentary review was applied to collect necessary data and information. So, secondary data were obtained from national surveys and statistical sources of governmental organizations. Data were analyzed using multiple regression. We followed the Baron and Kenny’s (1986) three-step procedure to test mediating relationships between variables. Results generally showed that drought duration had destructive effects on rural livelihood capitals and outcomes, while the negative influences of drought severity were far more restricted than drought duration. Complete mediation of livelihood assets in the relationship between drought intensity and inequality was confirmed. We also found support for partial mediation of livelihood assets in the relationship between drought severity and duration with the added value of the agricultural sector as well as in the relationship between drought duration and inequality.     

Development of an ecological impact assessment model for dam construction

The purpose of this study was to develop a model for assessing the ecological value of a dam reservoir. Various evaluable characteristics (“elements”) that influence the ecology of the target area around the dam were grouped into three classes: (1) physical elements, such as altitude, slope, and aspect; (2) vegetation elements, such as forest physiognomy, vegetation type, age class, diameter at breast height (DBH) class, and density; and (3) habitat elements, such as ecological conditions, vegetation conservation classification, and frequency of wildlife appearances. The evaluation standard was quantified considering the ecological function of each element. The developed assessment model was applied to the Yeongju Dam in the Nakdong River basin in Korea. This study assumed that the ecological condition before the dam construction was 100 %. The results of this study showed that the physical, vegetation, and habitat elements were downgraded to 82.8, 95.5, and 90.7 %, respectively, after the construction of the dam. The overall ecological value was estimated to be 90.0 % and thus decreased by 10.0 % due to dam construction. Additionally, by combining the results for the evaluation elements, an ecologically healthy area was selected. The results of this study should prove useful for quantifying ecological impact and for establishing an ecological restoration plan for dam reservoirs.     

Trends in health policy and systems research over the past decade: still too little capacity in low-income countries

BACKGROUND: The past decade has seen several high-level events and documents committing to strengthening the field of health policy and systems research (HPSR) as a critical input to strengthening health systems. Specifically, they called for increased production, capacity to undertake and funding for HPSR. The objective of this paper is to assess the extent to which progress has been achieved, an important feedback for stakeholders in this field. METHODS AND FINDING: Two sources of data have been used. The first is a bibliometric analysis to assess growth in production of HPSR between 2003 and 2009. The six building blocks of the health system were used to define the scope of this search. The second is a survey of 96 research institutions undertaken in 2010 to assess the capacity and funding availability to undertake HPSR, compared with findings from the same survey undertaken in 2000 and 2008. Both analyses focus on HPSR relevant to low-income and middle-income countries (LMICs). Overall, we found an increasing trend of publications on HPSR in LMICs, although only 4% were led by authors from low-income countries (LICs). This is consistent with findings from the institutional survey, where despite improvements in infrastructure of research institutions, a minimal change has been seen in the level of experience of researchers within LIC institutions. Funding availability in LICs has increased notably to institutions in Sub-Saharan Africa; nonetheless, the overall increase has been modest in all regions. CONCLUSION: Although progress has been made in both the production and funding availability for HPSR, capacity to undertake the research locally has grown at a much slower pace, particularly in LICs where there is most need for this research. A firm commitment to dedicate a proportion of all future funding for research to building capacity may be the only solution to turn the tide.     

Allocation rule for open-loop recycling in life cycle assessment

Recycling of a product can lead to the same product or to other products. Within the Inventory Analysis of LCA, the first process is called closed-loop recycling and poses relatively small methodological problems, whereas the second, open-loop recycling, involves major allocation problems. Basically, open-loop recycling creates a new, larger system which should be treated as one system in the inventory analysis from a scientific point of view. Since this is frequently not possible, allocation rules have to be applied in order to treat one of the subsystems separately. In this review, the different allocation rules proposed are presented and discussed with respect to the criteria of mathematical neatness, feasibility and justice/incentive for both producers and users of secondary raw materials.

Bladder preservation by concurrent chemoradiation for muscle-invasive bladder cancer: Applicability in low-income countries

Background

Radical cystectomy is the standard treatment for patients with muscle-invasive urinary bladder cancer; however, is associated with major treatment – related morbidity. Furthermore, a significant proportion of patients are deemed unsuitable for surgery due to inoperability, advanced age, and/or comorbid conditions. As such, several groups have explored effectiveness of less radical therapeutic strategies that aim at bladder preservation. Nonetheless, there is scarcity of reports assessing the applicability of urinary bladder-sparing outside developed countries.

Aim

Determine the achievable outcomes for patients with muscle-invasive urinary bladder cancer treated via bladder-sparing techniques in a low income country.

Materials and methods

Fourteen consecutive patients with a diagnosis of muscle-invasive urinary bladder cancer (clinical stage; T2-3N0M0) were treated via a bladder-sparing approach at King Hussein Cancer Center (Amman, Jordan) between 2005 and 2009. Records were electronically retrieved and retrospectively analyzed and included 11 males and 3 females from 41 to 74 years of age (median age, 61). Initial therapy consisted of trans-urethral resection of bladder tumor (TURBT) followed by induction chemotherapy then irradiation (4500cGy) with concurrent platinum-based chemotherapy. Urological evaluation directed additional therapy in a proportion of patients with irradiation (up to 6400 cGy) in patients who achieved CR.

Results

Eleven patients were evaluable for pathological response at time of re-staging; of whom 8 (73%) achieved CR and 3 (27%) achieved partial response (PR). In all but one patient; combined-modality treatment was well tolerated. After a median follow-up of 18.5 months (range, 3–48 months); 5 of 8 (62.5%) patients with CR were alive.

Conclusions

Bladder-sparing strategies via concurrent chemoradiation for muscle-invasive bladder cancer results in an acceptable rate of complete pathological response with adequate short-term outcomes. This approach appears applicable in low-income countries.     

Life Cycle assessment of a plastic packaging recycling system

Goal, Scope and Background.  The object of the study is the Italian system of plastic packaging waste recycling, active until 2001, that collected and mechanically recycled the post-consumer PE and PET liquid containers. The phases of collection, compaction, sorting, reprocessing and refuse disposal were individually analysed and quantified in terms of energy and material consumptions as well as of emissions in the environment. The work is the result of a joint research project with the Italian Consortium for Packaging (CONAI), carried out in co-operation with the main Italian companies active in the field. The main aim was the quantification of the real advantage of plastic container recycling and the definition of criteria, at the same time environmentally compatible and economically sustainable, for their management. Main Features  For each of the unit processes, and in order to increase the data quality, all the data of interest were collected during technical visits to several selected plants active in Italy or deduced by official documents and certificate declarations of the same companies. To allow comparison of resource consumption and environmental pollution from different management scenarios producing different products, thebasket of products method was applied. Results  The results indicates that the production of 1 kg of flakes of recycled PET requires a total amount of gross energy that is in the range of between 42 and 55 MJ, depending on whether the process wastes (mainly coming from sorting and reprocessing activities) were sent or not to the energy recovery. The same quantity of virgin PET requires more than 77 MJ. The energetic (and then environmental) saving is so remarkable, even for PE, being 40–49 MJ for the recycled polymer and about 80 MJ that for the virgin polyolefin. The calculations were made with the reasonable assumption that the final utilisation can use the virgin or the recycled polymer without any difference. Conclusions and Outlook  The analysis defined and verified a suitable tool in the field, based on objective data, for comparing different coherent scenarios of waste management politics. This allows one to propose the extension of the tool under different collection schemes, as well as for different systems of packaging recycling. As an immediate consequence of the success of the present study, the joint-research programme with CONAI has been extended for another three years. The focus will be the Italian system for paper and paperboard recycling and that for all plastic packagings. In parallel, a different study has been scheduled with reference to the integrated solid waste management of the Regione Campania, the largest and most populated area in the South of Italy.
