Currently a range of modular smartphones is emerging, including the Fairphone 2, Puzzlephone, Google's Project ARA, RePhone, LG's G5 and others. In an industry of perceived short product cycles a modular design concept might become crucial for longer product lifetimes. The paper provides an overview on latest product developments and assesses these against environmental criteria, including longevity,...
Current trends regarding telco network equipment evolution and changing paradigms in energy generation and power supply allow for a re-design of telco network production sites: On the one hand general-purpose hardware together with design ideas borrowed from IT data centers enter the telecom's world and on the other hand concepts of own and de-centralized electrical energy generation and power supply...
This paper presents a field study investigating the usage, configuration changes regarding end-devices, power consumption and bandwidth usage of the campus-wide local network, including observations of negotiated link speeds and fluctuations of our clients. On this basis, the publication includes a first model of a usage-driven optimization by switch-side bandwidth throttling. In our approach we examine...
The subject of this research is to find a process applicable to recycling FPC system adding extra functionality in the polymeric material without photo sensitive agent. We chose PBW (Proton Beam Writer) as an option. The potential impact by charge can modify electronic state and chemical bonding. Acceleration voltage and specific charge limit the depth of material modification. Proton is preferred...
We previously proposed sustainability indicators to evaluate information and communication technology solutions and services. These sustainability indicators are based on the following concepts: (1) the triple bottom line forms the basis of the evaluation criteria, (2) the same unit is used for every evaluation criterion, and (3) the sustainability indicators can be used to measure a diverse range...
In France is estimated a generation of about 17 and 23 kg per year of WEEE per inhabitant. However, in 2014, the return rate for household WEEE reached only 38% of the total market input. The French regulation targets higher collection rates for the next years: 45% between 2016 and 2019, and 65% after 2019 of the total market input. The aim of this work was to quantify the real environmental benefits...
This paper presents work carried out to address the shortage of a reliable means for determining the future arisings of historic WEEE levels in Ireland. By using modelling techniques in conjunction with available databases, researchers were able to determine WEEE levels and historic WEEE percentages for Ireland over the period of 2000 to 2020. The data generation focused on those EEE types which contribute...
After decades of developing corporate sustainability in Taiwan, the ICT sector has assumed the most important role in promoting corporate sustainability. Of the 13 corporations in the DJSI, nine are in the ICT sector. The corporate sustainability programs of such companies should be reevaluated in terms of their contributions to global sustainable development. This study analyzes whether the practices...
This paper discusses of the feasibility of ecodesign requirements on computer servers and presents a case study. Computer servers have been analysed in an ecodesign preparatory study. For the most representative products, the least life cycle cost (LLCC) has been identified: it minimizes the total cost of ownership for the consumer and fosters manufacturers to improve their products with existing...
The aim of the work was to ensure the after-market supply of an industrial robot handheld terminal independently from the original equipment manufacturer. Therefore, a remanufacturing process was developed. Additionally, an upcycling of the unit was realized by fixing the malfunctions of the original handheld terminal. Initially the malfunctions of the original handheld terminal were analyzed. Based...
Discarded electrical and electronic equipment (EEE) is a rapidly growing waste stream. This has increased, in part, because advances in technology have contributed to shorter product lifetimes. As such, waste electrical and electronic equipment (WEEE) has received increasing attention from policy makers. Previous research has revealed the large proportion of end-of-life consumer electronics disposed...
Repair is a way to extend the life of a product. In a circular economy where resource loops are closed to a maximum extent, repair belongs to the ‘inner loops’. Repairing a product is a way to preserve value by slowing down the product's economic devaluation. The aim of the paper is the development of a reparability indicator: a measure to determine the ease of repair of a product. The indicator is...
Growing number and complexity of material related regulatory regulations compel electronics manufacturers to rethink product compliance. Can your company state with confidence they can identify every substance in the final product, and from where each part was sourced, by all direct and indirect suppliers? The partly long supply chain is a challenge considering the short time and limited resources...
As many other electronic products complex set top boxes offer a variety of (secondary) functions, e.g. a hard disk recording, high definition and network connectivity. Minimum Efficiency Performance Standards (MEPS) for voluntary or mandatory initiatives use allowances to accommodate for these functionalities. With increasing functionality also the number of allowances tends to increase. The problem...
A customized assessment software tool was built by Innolux Corporation to help the designer assessing carbon footprint for each supply chain company. This Chinese language based carbon footprint automated calculation software - PCF system was developed in 2013. The purpose of this system is to assist automation in using the method in carbon footprint calculation of products for SMEs in Taiwan. In...
Innovations in the lighting sector, such as LED-based light sources, have opened up unprecedented possibilities to both save energy and improve the quality of lighting. There is growing evidence of light's importance for human health, moods, work productivity and quality of life in general; but the uptake of new solutions is still rather slow in society. The public sector can play an important role...
To set the stage for the conference it is of interest to take a look back in order to try a look forward at potential upcoming research trends. For this purpose research topics addressed in Electronics Goes Green conferences since 2000 are quantitatively investigated with a keyword density analysis. The focus is on analysing the development of research topic clusters over time providing an expert...
The objectives of ‘feasibility study for setting-up reference values to support the calculation of recyclability/recoverability rates of electr(on)ic products’ commissioned by the Joint Research Centre are to define key harmonized methodological aspects to develop reference values on recycling and recovery rates (RR rates) of materials and components for electr(on)ic products to calculate recyclability...
Circular business models are considered to be one of the key building blocks in the transition to a Circular Economy, but the viability of such business models is often dependent upon supporting policies. Relevant policies include support for waste infrastructure, regulatory frameworks, taxes and charges, and various informative instruments. This contribution reviews the literature on circular economy...
