Environmental influence assessment of China’s multi-crystalline silicon (multi-Si) photovoltaic modules considering Recycling Process
Solar Energy, 2017Co-Authors: Beijia Huang, Juan Zhao, Jingyang Chai, Feng Zhao, Xiangyu WangAbstract:Abstract The environmental burden of multi-Si PV modules in China has been discussed in existing studies, however, their data are mostly from local enterprises, and none of their environmental assessment involves the decommissioning and Recycling Process. This study quantitatively assesses the life-cycle environmental impacts of Chinese Multi-crystalline Photovoltaic Systems involving the Recycling Process. The LCA software GaBi is applied to establish the LCA model and to perform the calculation, and ReCiPe method is chosen to quantify the environmental impacts. LCA of production Process reveals that Polysilicon production, Cell Processing and Modules assembling have relatively higher environmental impact than Processes of Industrial silicon smelting and Ingot casting and Wafer slicing. Among the 14 environmental impact categories evaluated by ReCiPe methodology, the most prominent environment impacts are found as Climate Change and Human Toxicity. LCA including Recycling Process reveals that although Recycling Process has environmental impact, the Recycling scenario has less environmental impact by comparing with the landfill scenario. Among the five manufacturing Processes and Recycling Process, environmental impacts of polysilicon production, cell Processing and modules assembling have relatively higher uncertainty, probably because that the environmental impact of these Processes is high, and standard error of parameters such as electricity, aluminum and glass in the three Processes are high. Findings of our study indicate that proper measures should be taken in the high pollution Processes such as polysilicon production and cell Processing. In addition, efforts should also be made to enhance the recovery rate and seek for more environmental friendly materials in the Recycling Process.

Characterisation of LDPE residual matrix deposited on glass fibres by a dissolution/reprecipitation Recycling Process
Composites Part A-applied Science and Manufacturing, 1999Co-Authors: N. E. Zafeiropoulos, Constantine D. Papaspyrides, P.c. Varelidis, T. Stern, Gad MaromAbstract:Abstract Low density polyethylene (LDPE) residual matrix remaining on short glass fibres, following a Recycling Process of LDPE/glass composites, were examined. The residual matrix was characterised by scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). DSC curves showed the existence of a different type of crystallinity, probably occurring because of the history of the sample along the stages that comprise the Recycling Process. Optical microscopy revealed that, in a subsequent use of the recycled fibres with new polyethylene matrix, the residual matrix can recrystallise to form a transcrystalline layer. The size of this layer seems to depend on the amount of the residual matrix.

development of a Recycling Process for li ion batteries
Journal of Power Sources, 2012Co-Authors: T Georgimaschler, H. Heegn, Reiner Weyhe, Bernd Friedrich, M. RutzAbstract:Abstract In cooperation with the industrial project partners ACCUREC Recycling and UVR-FIA a Recycling Process specially dedicated to portable Li-ion batteries was developed combining a mechanical pretreatment with hydro- and pyrometallurgical Process steps. Therefore not only the recovery of cobalt but also the recovery of all other battery components, especially of lithium was of interest. Besides the characterization and evaluation of all generated metallic material fractions, the focus of the research work was the development of a pyrometallurgical Process step in an electric arc furnace for the carbo-reductive melting of the fine fraction extracted from spent Li-ion batteries. This fine fraction mainly consists of the cobalt and lithium containing electrode material. Since a selective pyrometallurgical treatment of the fine fraction for producing a cobalt alloy has not been done before, the proof of feasibility was the main aim.

a laboratory scale lithium ion battery Recycling Process
Journal of Power Sources, 2001Co-Authors: Marcello Contestabile, Stefania Panero, Bruno ScrosatiAbstract:After reviewing the status of the lithium battery waste treatment and, in particular, outlining the technical and practical aspects of this operation, we describe some preliminary activity in progress in our laboratory mainly directed to the development and evaluation of a multi-step Recycling Process. Although this Process is still in an exploratory phase, the preliminary results obtained in our laboratory suggest that the Process may be of some practical interest since it gives promises of obtaining a good recovery of the battery components by rather efficient and easily achievable operations.
