This book serves as a starting point for readers to understand the concepts of the circular economy and bioeconomy and how they can be applied to industrial processes. The notion of having eco-friendly industries is a recent development, with a growing interest in the environmental impact of industrial practices, particularly with regard to resource recovery practices for valuable nutrients and byproducts, which aligns with the circular economy and bioeconomy concepts that aim to establish a "continuous flow of materials." Currently, the focus is on studying the environmental impact and developing strategies to achieve a balance with water ecosystems for sustainable and equitable coexistence. The success of these concepts will depend on a robust framework that evaluates the environmental trade-offs and co-benefits of improving industry practices to enhance ecosystem protection. This book introduces circular economy practices in industry, along with tips, procedures, recommendations, and lessons learned.
