Societal benefit assessment: an integrated tool to support sustainable toy design and manufacture

A framework and methodology for assessing the societal benefits of a product was developed based on the assertion that, in order to access future diminishing resources, manufacturers will need to demonstrate both the social and environmental benefits of their products. This paper follows on from this published research and presents an integrated tool to support the implementation of this framework and methodology within the toy industry during the design and development phase. A simulated case study is used to exemplify the application of this tool and to support the concluding discussions

An integrated tool to support sustainable toy design and manufacture

Whilst the importance of considering the positive societal benefits of a product, in addition to other social, economic and environmental factors, has received wider recognition, its definition, concept, and integration into product design are not so well developed and studied. A literature review on sustainable design identified the potential of Social Life-Cycle Assessment as a tool to measure societal benefits of products; however further analysis of sustainable assessment methods highlighted the lack of a coherent definition and method for achieving this. This paper presents a framework for including societal benefits within a product portfolio management process and a prototype tool which aims to support the implementation of the framework within the toy industry, specifically on the societal benefit assessment of the products during the first stage. Finally a simulated case study of three toys is used to exemplify the intended application of this tool and to support the concluding discussions

Assessment of the capability of an optical sensor for in-line real-time wastewater quality analysis in food manufacturing

This work investigates the use of a commercial optical product monitor to achieve in-line real-time water content analysis. Test fluids were used and optical measurements of attenuation of light intensity at four colours were made. These measurements were used to identify any relationship between these and the water quality parameters of turbidity and colour. Variation in light attenuation for turbidities up to 1700 NTU was successfully resolved by the instrument, with optical data for turbidities ≥ 20 NTU fitting well the Beer-Lambert model. The sensor was also able to clearly identify the effect of filtering out suspended solids with unfiltered samples (apparent colour) exhibiting significantly higher attenuation coefficients than filtered samples (true colour). Further studies will concentrate on whether the instrument can analyse samples with turbidities higher than 1700 NTU, together with further investigating the variation in the attenuation coefficient seen with turbidity and colour of light
