the best vendor selection for conducting the Recycled material based on a hybrid mcdm model combining danp with vikor
Resources Conservation and Recycling, 2012Co-Authors: C H Hsu, Fukwun Wang, Gwohshiung TzengAbstract:Abstract Environmentally conscious manufacturing and product recovery (ECMPRO) has become an obligation of manufacturers, and it has been extended to be the policy and strategy of businesses. Producing recyclable products and using Recycled Materials are optimal strategies for ECMPRO. Vendor selection (VS) is one of the multiple criteria decision-making (MCDM) problems in strategic supply chain management. The purpose of this article is to propose how the best selection to conduct the Recycled Materials can be implemented for enhancing and increasing the efficiency of using resources in the manufacturing process through Recycled Materials VS. Aluminum composite panel (ACP) is a global product, and ACP companies in Taiwan use Recycled Materials in more than 80% for their products on a quantity basis. Therefore, we selected the ACP industry of Taiwan as an empirical model to study VS and to reveal methods of improving gaps in each criterion for achieving the aspired levels of performance. We use the MCDM model combining DEMATEL-based on ANP (called DANP) with VIKOR to solve the Recycled Materials VS problems of multiple dimensions and criteria that are interdependent, instead of the independent assumption of an analytic hierarchy process, for mimicking the real-world scenario.

innovative panels with Recycled Materials thermal and acoustic performance and life cycle assessment
Applied Energy, 2014Co-Authors: Paola Ricciardi, Elisa Belloni, Franco CotanaAbstract:Insulation is one of the most effective methods intended for reducing energy consumption in both heating and cooling of buildings. Selecting the right Materials and determining the optimum insulation thickness in building insulation application is an important issue. Moreover it is important to use green insulating Materials in order to limit the environmental impact in the use of these solutions. A growing interest is focused on the incorporation of low cost Recycled Materials in building products and their potential use as insulating panels for both new buildings and refurbishments.

Applied Energy, 2014Co-Authors: Paola Ricciardi, Elisa Belloni, Franco CotanaAbstract:Abstract Insulation is one of the most effective methods intended for reducing energy consumption in both heating and cooling of buildings. Selecting the right Materials and determining the optimum insulation thickness in building insulation application is an important issue. Moreover it is important to use green insulating Materials in order to limit the environmental impact in the use of these solutions. A growing interest is focused on the incorporation of low cost Recycled Materials in building products and their potential use as insulating panels for both new buildings and refurbishments. In this paper two panels were investigated, composed by waste paper and textile fibres, joined by glue, with a total thickness of 12 mm and 20 mm respectively. The study is focused on the thermal and acoustic characterisation of the panels, in order to provide accurate data for a reliable building integration. Thermal performance was evaluated by using the hot-box apparatus, according to UNI EN ISO 8990. A good thermal behaviour was found for all the investigated panels: k-values vary in the 0.034–0.039 W/m K range. The investigated panels could be a valid solution in place of classic insulation systems, even though thermal resistance is strongly influenced by the environmental humidity, the rate of the compression, and the presence of air between the layers. Therefore a thermal infrared camera was also used during the measurements, aiming to investigate the weak points of the assembled panels and to select the positions of the sensors. The acoustic absorption coefficient was determined by means of a Kundt’s tube, in compliance with ISO 10534-2. The Noise Reduction Coefficient (NRC – the arithmetic value of the absorption coefficient at the frequencies 250, 500, 1000 and 2000 Hz) of the samples varies in 0.23–0.38 range, depending on the layer thickness. Finally an initial Life Cycle Assessment of the proposed solutions was considered and compared to the performance of other replaceable insulating Materials. Results showed that the panel composed by Recycled papers and textile fibres causes relative large energy consumptions and a high global warming potential. The importance of this kind of insulation system is due to the use of Recycled Materials: both the waste paper and the TNT fibres should be disposed by means of a large use of energy. This way they will be re-used and the cost for the production of the panels is very low. A disadvantage of these panels could be their high density (about 433 kg/m3): the future step for this work will be the improvement of this new insulating type in order to obtain a competitive solution on the market. The manufacturing of lighter solutions will allow the panels to be more competitive on the market in terms of embodied energy and GHG emissions.

rheological properties of asphalt binders modified with Recycled Materials a comparison with styrene butadiene styrene sbs
Construction and Building Materials, 2020Co-Authors: Sajjad Hassanpourkasanagh, Perviz Ahmedzade, Alexander Fainleib, Ali BehnoodAbstract:Abstract The thermo-mechanical properties of asphalt mixtures are highly influenced by the properties of the asphalt binders. The poor performance of the asphalt binders can lead to several distresses in asphalt pavements such as rutting and fatigue cracking. One of the common approaches to mitigate the asphalt pavement distresses is modifying the asphalt binders, which can happen by using a wide variety of modifiers or additives. In this research, the effects of various amounts of a green composite modifier (CM) made from Recycled Materials on the performance of a base asphalt were investigated. In addition, using the same base binder, the performance of this modifier was compared with that of Styrene-Butadiene-Styrene (SBS) which is the most common modifier used in many regions. The use of CM obtained from Recycled Materials can provide both environmental and economic benefits. It could also be expected to obtain technical improvements upon the addition of this modifier. The CM contained High-Density Polyethylene (HDPE), Ethylene Propylene Diene Monomers (EPDM), Ground Tire Rubber (GTR), and bitumen. The performance of the binders was evaluated by conducting a wide range of tests including penetration, softening point, viscosity, conventional performance grading, linear amplitude sweep, and multiple stress creep recovery. The findings from this research indicated that both modifiers improved the rheological properties of the binders. Moreover, although CM slightly showed negative impacts on the fatigue life, it was found to show comparable performance with that of SBS.
