The article is focused on new application of eco-design in the field of electronics. The concept of circular economy is a new trend in manufacturing technologies. It is not clear when an electronic product, being the last phase of lifecycle, will be defined as a waste. According with principles of circular economy there is no waste, only resources. The designer needs to design the electronic products taking in consideration the amount of resources which is the outcome of PLM. The Waste of Electronic and Electric Equipments (WEEE) is used as an input for another industrial process. Thus, the cycle is completed, nothing is lost and there is no pollution.
expensive and with average efficiency. The most common and widely used methods for advanced heavy metal removal are: chemical precipitation, flotation, flocculation, sedimentation, solvent extraction, oxidation/reduction and dialysis/electro-dialysis, reverse osmosis, ultra filtration, electrochemical deposition, ion exchange and adsorption e.g.Choosing one or more complex solutions is subject of efficiency and cost analysis reported at large quantity of wastewater. Among these, adsorption technologies have several advantages: easy operation and well known technology, inexpensive equipment, less sludge, adsorbents' reuse after desorption. In water the heavy metals cations are hydrated with different bipolar water molecules.Heavy metals (cadmium, copper, zinc, nickel) removal by adsorption was reported on, sugar beet pulp [7] Materials and MethodsRaw Fly Ash was collected from the electrostatic filters in the AbstractIncreased urbanization and industrialization led to excessive release of wastes into the environment; one of them, causing many problems not only to the environment but also to human health, is fly ash resulted from coal combustion. One of the solutions for solving these problems would be fly ash reutilization as an adsorbent for wastewater treatment and for obtaining new and efficient materials such as zeolites. Class "F" fly ash collected from C.H.P. Craiova from Romania was used for obtaining new zeolite materials for advanced wastewater treatment. This material was characterized by AFM, XRD, FTIR, SEM to outline the crystalline and morphology modifications. Hydrothermal modified fly ash using NaOH was used for heavy metals removal (Cd 2+ , Cu 2+ and Ni 2+ ) from synthetic wastewaters containing one, two and three pollutants. For obtaining a maximum efficiency during the adsorption process the adsorption conditions (contact time, optimum amount of substrate) were optimized. These parameters were further used in thermodynamic and kinetic modeling of the adsorption processes. The uptake of Cd 2+ , Cu 2+ and Ni 2+ was followed by a Langmuir adsorption isotherm and the maximum uptake capacity was estimated to be 95.24 mg/g Cd 2+ , 107.52 mg/g Cu 2+ from aqueous solution with two cations. Correlated with the surface structure, composition and morphology the adsorption kinetic mechanisms and the substrate capacities are further discussed.
PLM is a transformation strategy built on shared access to a single knowledge base, data and processes related to our products. This strategy allows us to grow and to control the rate of change of products or degree of innovation. The purpose of this paper is to find out the importance of innovative processes on Product Lifecycle Management (PLM) integration strategies with the objective to help companies to answer to the main market needs. In the case study we propose to analyze the innovation potential influence over electro-mechanic manufacturing process considering its specific tools. To exemplify our researches we approached the PLM as a multi-dimensional topic and we intent to explore the innovation complex metrics dimensions and help the reader gain a broad perspective of PLM in the Romanian industry. By using this approach, we can score, weight and prioritize customer assessment for different stages of product development process and to take in consideration the most likely changes that will improve the process. There are identified and assessed five innovation complex metrics used in PLM process stages within a complex Product Development Process. Also, based on this metrics, we create and and analyze "PLM innovation matrix" and a related chart.
