摘要

目前,皮革行业正面临着严重的威胁,因为人们正在努力消除由皮革废料产生造成的环境污染问题。垃圾填埋场必须用来处理对环境有害的皮革废料。在皮革加工过程中使用不同的化学品会产生固体、液体和气体形式的废物,造成环境污染。皮革/废纸基材料的开发是由再生皮革行业推动的。本研究旨在从含铬皮革废料(CCLW)中制备一种聚合电解溶液(PES),用于碳化颗粒(CP)、微纤化纤维素(MCF)和聚乙二醇(PEG),以实现其在可持续能源生产中的潜在用途。在这种方法中,消耗功率(可充电)是基于氧化还原过程的。利用场发射扫描电镜(FE-SEM)、能量色散x射线能谱(EDX)和傅里叶变换红外光谱(FTIR)研究了PES的物理和化学特征。在PES上,使用万用表和流变特性演示了能量产生。结果表明,每电池产生的能量电压为1101.12±1.00 mV,电流为639.12±0.42 mA,电阻为88.77±0.17。流变学试验在25°C下进行,PES质量分数为8%,剪切应变率逐渐增加,从0.01到100 s−1。这项工作介绍了对从废物中回收材料和能源的解决方案以及从质量和能量平衡中获得的解决方案进行比较检查的研究工作的环境结果。

Carbonization of chrome containing waste: Sustainable energy, cost-effective and recycling
The leather industry is currently under severe threat from efforts to eliminate environmental pollution issues caused by the generation of leather waste. Landfills must be used to dispose of leather waste, which harms the environment. Use of different chemicals during leather processing produces wastes in solid, liquid and gaseous form: contribute to environmental pollution. The development of leather/paper waste-based materials is an offer promoted by the recycled leather industry. A study is conducted into this work to prepare a polymerized electrolytic solution (PES) from chrome-containing leather waste (CCLW) for carbonized particles (CP), microfibrillated cellulose (MCF), and polyethylene glycol (PEG) for their potential use in sustainable energy production. In this method consuming power (rechargeable) is based on the redox process. Field emission-scanning electron microscopy (FE-SEM), Energy-dispersive X-ray spectroscopy (EDX), and Fourier-transform infrared spectroscopy (FTIR) were used to investigate the physical and chemical features of PES. On PES, energy generation was demonstrated using a multimeter and rheological properties. The results show that energy was produced with a voltage of 1101.12 ± 1.00 mV per cell, a current of 639.12 ± 0.42 mA per cell, and a resistance of 88.77 ± 0.17 per cell. Rheological tests were conducted at 25 °C with 8% wt/vol of PES and gradually increased shear-strain rates of 0.01 to 100 s−1. This work presents the environmental results of a study effort on the comparative examination of solutions for material and energy recovery from waste, along with those derived from mass and energy balances.
