Worldwide waste valorization and recovery of non-utilized components/unreacted compounds/ side streams/ byproducts are being researched upon. These are indispensable for environment protection, process economics and emerging technology development concepts like zero liquid discharge. Existing techniques suffer from problems like secondary contamination, complex design, costly raw materials, and extreme process conditions. Membrane crystallization offers a robust and simple solution for sustainable recovery of valuables from effluent streams. This review was undertaken to critically assess efficacy of membrane crystallization for value-added product recovery integrating the basic principles of process intensification: economics, efficiency, and sustainability. Processes like membrane distillation integrated crystallization, osmotic membrane crystallization, concentrative pressure-driven crystallization were analysed with respect to selective separation, byproduct recovery percentage, and viability. Several approaches on process intensification and comparative performance evaluation were discussed. Integrative technology options combining conventional methods like precipitation, evaporative crystallization as well as standalone versions were explored in detail to ascertain techno-commercial viability. It was concluded that membrane crystallizers provides an efficient and eco-friendly means for value added product recovery from diverse waste streams. This critical review on insights aims to formulate concrete guidelines towards applicability of membrane based crystallization for value added product recovery.
