Social Life Cycle Assessment

When considering the sustainability of production processes, research studies usually emphasise environmental impacts and do not adequately address economic and social impacts. Toy production is no exception when it comes to assessing sustainability. Previous research on toys has focused solely on assessing environmental aspects and neglected social and economic aspects. This paper presents a sustainability assessment of a toy using environmental life cycle assessment, life cycle costing, and social life cycle assessment. We conducted an inventory analysis and sustainability impact assessment of the toy to identify the hotspots of the system. The main environmental impacts are eutrophication, followed by terrestrial eco-toxicity, acidification, and global warming. The life cycle costing approach examined the economic aspect of the proposed design options for toys, while the social assessment of the alternative designs revealed social impacts along the product life cycle. In addition, different options based on the principles of the circular economy were analysed and proposed in terms of substitution of materials and shortening of transport distances for the toy studied.

The World

The circular economy (CE) model has become highly relevant in recent years, with the electronics industry being one of the divisions that have thought about its application. Regardless of just a constrained measure of writing being accessible on waste electric and electronic equipment (e-waste), electronic waste or e-waste is a developing and quickly developing test for waste administration in the world. E-waste is a term for electronic items that have turned out to be undesirable, non-working, or outdated, and have basically come to the 'part of the arrangement', inside only a couple of brief years, given the quick innovative advances inside the business. E-waste is created from anything electronic —PCs, TVs, screens, PDAs, PDAs, VCRs, CD players, fax machines, printers, and coolers— and is commonly broken into two classes, information technology (IT) and consumer electronics (CE), on account of divergent systems and technologies required for recycling these products.

This paper introduces some challenges involved in assessment of service life and durability in the context of circular economy principles. It proposes a possible agenda for service life planning in a resource-constrained economy. Aspects considered include the reuse of materials and components over multiple life cycles within built assets. The interface between life cycle assessment and costing techniques, service life planning, and resilience against changing climate and performance requirements is considered. The current codes and standards, in particular within ISO 15686 series on service life, CEN 15643 on integrated sustainability assessment, and ISO 20887 on design for disassembly, are briefly described together with some implicit challenges. The contributions of CIB Task Groups are also considered, in particular CIB Task Groups 16, 39, and 115 and CIB W80 on prediction of service life of building materials methodologies. Several current EU research and development projects are briefly mentioned, in particular BAMB (Buildings as Material Banks).

Content Type

Purpose The purpose of this paper is to develop and optimize a mathematical model based on a framework that integrates key concepts related to a circular economy (CE) and sharing economy (SE) for a leading manufacturer of laptops in India. Design/methodology/approach This study mathematically modelled the integration of sharing networks in a circular production system. This is done through an optimization package that deploys a multi-objective mixed-integer linear programming model. Findings This study evaluated the economic benefit and the environmental impact associated with the aforementioned integration in a production system. This study illustrated the inverse relationship between economic benefit and environmental impact and provided a set of solutions that can be used according to the case organizations goals, capacities and logistical capabilities. Research limitations/implications This study will aid similarly structured companies in adopting this approach to integrate sustainable practices in their production system. It also enumerated Industry 4.0 (I4.0) use-cases that can be used to effectively implement this mathematical model. Further research can be conducted using multiple companies in an inter-dependent network to maximize synergy. Practical implications This study will help to better understand the role of sharing networks in the circular economy model especially in the consumer electronics industry. Originality/value This study is the first of its kind to mathematically model the integration of aspects related to SE and CE. It also validates the aforementioned model using a numerical case-study and offers decision-support to key executives within the case organization.

The goal of the circular economy (CE) is to transition from today's take-make-waste linear pattern of production and consumption to a circular system in which the societal value of products, materials, and resources is maximized over time. Yet circularity in and of itself does not ensure social, economic, and environmental performance (i.e., sustainability). Sustainability of CE strategies needs to be measured against their linear counterparts to identify and avoid strategies that increase circularity yet lead to unintended externalities. The state of the practice in quantitatively comparing sustainability impacts of circular to linear systems is one of experimentation with various extant methods developed in other fields and now applied here. While the proliferation of circularity metrics has received considerable attention, to-date, there is no critical review of the methods and combinations of methods that underlie those metrics and that specifically quantify sustainability impacts of circular strategies. Our critical review herein analyzes identified methods according to six criteria: temporal resolution, scope, data requirements, data granularity, capacity for measuring material efficiency potentials, and sustainability completeness. Results suggest that the industrial ecology and complex systems science fields could prove complementary when assessing the sustainability of the transition to a CE. Both fields include quantitative methods differing primarily with regard to their inclusion of temporal aspects and material efficiency potentials. Moreover, operations research methods such as multiple-criteria decision-making (MCDM) may alleviate the common contradictions which often exist between circularity metrics. This review concludes by suggesting guidelines for selecting quantitative methods most appropriate to a particular research question and making the argument that while there are a variety of existing methods, additional research is needed to combine existing methods and develop a more holistic approach for assessing sustainability impacts of CE strategies.
