  • durability of concrete structures in marine atmosphere zones the use of chloride deposition rate on the wet candle as an Environmental Indicator
    Cement & Concrete Composites, 2010
    Co-Authors: Gibson Meira, C Andrade, C Alonso, J C Borba, M Padilha
    Abstract:

    Durability of concrete structures under marine environments has been studied for a long time. This work was focused on marine atmosphere zone and studied the deposition of chlorides on wet candle devices and its relation with chlorides accumulated into concrete. Concrete specimens with three different mixtures were exposed at places located at four different distances from the sea. Periodically, chloride profiles were obtained and analysed taking into account Environmental data. Results of numerical extrapolations show that chloride deposition rate on the wet candle can be used as an Environmental Indicator, helping to preview the expectancy of service life of concrete structures or suggesting minimum concrete cover thicknesses for a required service life. Regarding the studied region, service life decreases between 30% and 60% were observed when changing chloride deposition from 120 mg/m2 day to 500 mg/m2 day, which shows that chloride deposition plays an important role as an Environmental Indicator on service-life analysis of concrete structures in marine atmosphere zone.

  • Process of fruit peel waste biorefinery: a case study of citrus waste biorefinery, its Environmental impacts and recommendations
    Environmental Science and Pollution Research, 2019
    Co-Authors: Saurabh N. Joglekar, Pranav D. Pathak, Sachin A. Mandavgane, Bhaskar D. Kulkarni
    Abstract:

    Fruit peels are a rich source of cellulose, hemicellulose, phenolic compounds, and terpenic compounds. Thus, they have the potential to be a novel renewable, sustainable, and low-cost raw material (source) for the production of several value-added products based on framework and concepts such as waste hierarchy that includes biofertilizers, dietary fiber, animal feed, industrial enzymes, substrate for the bioactive compounds production, synthesis of nanomaterials, and clean energy (from residual biomass). With a view of evaluating the Environmental burden of biorefinery, a life cycle assessment (LCA) is performed for a representative citrus waste (CW) biorefinery. The functional unit used for LCA was set as 2500 kg of CW processed. The overall GWP was observed to be 937.3 kg CO_2 equivalent per 2500 kg of CW processed. On further analysis of the Environmental impact, it was found that different steps contributed significantly, as shown by the various Environmental Indicator values. Alternative advanced process intensification technologies like microwave and ultrasound-assisted steps replacing the conventional steps when implemented show considerable reduction in Environmental Indicator values. The variations in the contribution to Environmental Indicators should be considered during the design and process selection of biorefineries.
