Abstract

This article reviews the most recent advances on the contribution of electromembrane-based technologies to waste valorisation through their implementation in the sustainable recovery and storage of energy from waste streams. Two driving forces are considered, salinity and pH gradients. Recent advances and challenges in ion exchange membranes (IEMs) and bipolar membranes (BPMs) are presented. Reverse electrodialysis (RED) and reverse bipolar membrane electrodialysis (RBMED) are evaluated as primary batteries to harvest energy from salty streams. The potential of combining RED/ED and RBMED/BMED as sustainable secondary batteries is also presented. Overall, it is concluded that increasing the membrane performance is a key aspect to rise the maturity of the proposed technologies along with their adaptation to the different characteristics of current and future waste streams potentially available for energy recovery and storage.

废物价值化的电热膜工艺：能量回收和储存

这篇文章回顾了基于电解质膜的技术在从废物流中可持续地回收和储存能量方面的最新进展。文章考虑了两种驱动力，即盐度和 pH 梯度。介绍了离子交换膜（IEM）和双极膜（BPM）的最新进展和挑战。评估了反向电渗析（RED）和反向双极膜电渗析（RBMED）作为从含盐溪流中获取能量的主要电池的情况。此外，还介绍了将 RED/ED 和 RBMED/BMED 组合作为可持续二次电池的潜力。总之，得出的结论是，提高膜性能是提高拟议技术成熟度的一个关键方面，同时还能使这些技术适应当前和未来可能用于能量回收和储存的废物流的不同特性。

期刊介绍： The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
