Abstract
Endüstri 4.0 devrimi ve Nesnelerin İnterneti (IoT) gibi teknolojilerle dijitalleşme, kaynaklarımızın ve ekonomilerimizin döngüsel olmasını gerektirmektedir. Başta Avrupa Birliği olmak üzere tüm ülkeler, kritik hammaddelerin sorumlu tüketiminin, üretiminin ve geri dönüşümünün sürdürülebilir kalkınma hedeflerine ulaşmanın bir yolu olarak çok önemli olduğu konusunda hemfikirdir. Ömrünü tamamlamış ürünlerden kritik hammaddelerin geri kazanılması için uygun maliyetli bir geri dönüşüm yöntemi, madencilikten çok daha az çevresel etkiye sahiptir. Biyo & hidrometalurjik yöntemler, kritik hammaddelerin, özellikle nadir toprak elementlerinin (NTE) çıkarılması için hızlı gelişen, seçici, çevre dostu ve uygun maliyetli teknolojilerdir. Bu makale, ikincil kaynaklara genel bir bakış sağlamakta ve kritik hammaddelerin kazanımı için ekonomik bir yol olarak hizmet edebilecek bazı umut verici yöntemlerin kullanımına ilişkin yürütülen çalışmaların senaryosunu özetlemektedir.

Abstract
Digitalization with technologies such as industry 4.0 revolution and Internet of Things (IoT), it is requires our resources and economies to be circular. All countries, especially the European Union agree that responsible consumption, production and recycling of critical raw materials is essential as a means of achieving sustainable development goals. A cost-effective recycling method for the recovery of critical raw materials from end-of-life products has far less environmental impact than mining. Bio&hydrometallurgical methods are a fast developing, selective, eco-friendly, and cost-effective technologies for the extraction of critical raw materials especially rare earth elements (REE). This article provides an overview of secondary resources and summarizes presents scenario of studies carried out on the use of some promising methods which could serve as an economical means for recovering CRMs.
