生物材料经历了一个变革的过程，从最初作为可再生资源，到加工和储存的制造工厂，直到它们实现预期的治疗或诊断目的，成为医疗废物。然而，在这个生命周期中，生物材料可能容易受到污染，并通过各种机制，如水、土壤或空气中的水机械、热或生化过程，随后降解。这些因素引起了人们对生物安全的重大关切。其他的复杂性来自生物材料与其他材料的潜在融合，无论是相同类型还是不同类型。生物材料的使用影响其孔隙度、表面化学和结构强度，这些因素影响生物材料的可重复使用性。考虑到材料、加工参数、可持续性要求和自然资源的限制，生物材料的回收是必要的。不幸的是，到目前为止，这个话题得到的关注有限。在此背景下，本观点提供了一个简短的概述，分析和分类的报告，生物材料的回收，旨在发起讨论这一经常被忽视的主题。我们强调能源消耗和环境污染方面的挑战。然而，缺乏关于生物材料回收的既定协议和报告阻碍了对这些挑战和潜在解决方案的全面理解。然而，解决这些问题可以导致更有效的资源利用和减少对生物材料领域的环境影响。
Biomaterials undergo a transformative journey, from their origin as renewable resources to the manufacturing plants where they are processed and stored, until they fulfill their intended therapeutic or diagnostic purposes and become medical waste. However, during this life cycle, biomaterials can be susceptible to contamination and subsequent degradation through various mechanisms such as hydro-mechanical, thermal, or biochemical processes in water, soil, or air. These factors raise significant concerns regarding biological safety. Additional complexities arise from the potential amalgamation of biomaterials with other materials, either of the same kind or different types. Use of biomaterials influences their porosity, surface chemistry, and structural strength, and these factors affect biomaterials' reusability. Given the multitude of materials, processing parameters, sustainability requirements, and the limitation of natural resources, the recycling of biomaterials becomes necessary. Unfortunately, this topic has received limited attention thus far. In this context, this perspective provides a brief overview, analysis, and classification of reports on biomaterials recycling, aiming to initiate a discussion on this frequently overlooked subject. We highlight the challenges related to energy consumption and environmental pollution. However, the lack of established protocols and reporting on biomaterials recycling prevents a comprehensive understanding of these challenges and potential solutions. Nevertheless, addressing these issues can lead to more efficient resource use and reduced environmental impact in the field of biomaterials.
