The dramatic increase in biodiesel plant leads to oversupplied glycerol as its by product which requires industrial application for sustainability of biodiesel. The main focus of this study is the proper utilization of industrial waste pond ash for the preparation of various catalysts for the synthesis of glycerol carbonate . A series of catalysts were prepared by doping barium , lithium and potassium on the surface of pond ash collected from national thermal power plant (NTPC, Talcher, India). Among all the synthesized catalyst 20% Barium doped pond ash catalyst provided highest conversion of glycerol i.e. 98% and 94% glycerol carbonate yield respectively at mild reaction conditions. . 20% Ba doped pond ash catalyst was highly suitable for glycerol carbonate synthesis due to highest basic strength. The physicochemical properties of synthesized catalyst were studied through TGA-DSC, XRD, FT-IR spectra , SEM -EDX analysis . The catalytic performance as well as reaction parameters like temperature, time, DMC to glycerol molar ratio and catalyst loading percentage were optimized for better conversion of glycerol. Green metrics like E-factors , PMI are also studied to determine the sustainability and environmental impact of catalyst as well as transesterification reaction of glycerol. The overall evaluation of green chemistry for the work indicated that the synthesized catalyst is environmental benign in nature.

生物柴油工厂的急剧增加导致甘油作为副产品的供过于求，这需要工业应用来实现生物柴油的可持续性。本研究的主要重点是适当利用工业废池灰制备各种合成碳酸甘油的催化剂。通过将钡，锂和钾掺杂在从国家火力发电厂（NTPC，印度塔尔彻，印度）收集的池灰表面上，制备了一系列催化剂。在所有合成的催化剂中，掺有20％钡的池塘灰烬催化剂在温和的反应条件下提供了最高的甘油转化率，即分别为98％和94％的碳酸甘油酯收率。。20％Ba掺杂的池灰催化剂由于具有最高的碱性强度，因此非常适合于碳酸甘油酯的合成。通过TGA-DSC，XRD，FT-IR，SEM-EDX分析研究了合成催化剂的理化性质。优化了催化性能以及反应参数，如温度，时间，DMC与甘油的摩尔比和催化剂的负载百分比，以实现更好的甘油转化率。还研究了诸如E因子，PMI之类的绿色指标，以确定催化剂的可持续性和环境影响以及甘油的酯交换反应。这项工作对绿色化学的总体评价表明，合成的催化剂本质上对环境无害。优化了DMC与甘油的摩尔比和催化剂的负载百分比，以更好地转化甘油。还研究了诸如E因子，PMI之类的绿色指标，以确定催化剂的可持续性和环境影响以及甘油的酯交换反应。这项工作对绿色化学的总体评价表明，合成的催化剂本质上对环境无害。优化了DMC与甘油的摩尔比和催化剂的负载百分比，以更好地转化甘油。还研究了诸如E因子，PMI之类的绿色指标，以确定催化剂的可持续性和环境影响以及甘油的酯交换反应。这项工作对绿色化学的总体评价表明，合成的催化剂本质上对环境无害。
