信息存储介质是当前使用最广泛的电子产品之一,其大量使用也导致了废弃信息存储介质的快速产生.其作为信息载体的特殊性,为这类电子废弃物的处理提出了新的挑战和更高的技术要求.根据信息存储介质的不同存储机理,提供了对应的安全销毁方法.对于磁存储介质,磁场消磁法具有技术优势和环境优势,发展前景最为广阔；对于半导体存储介质,机械破碎法是最有效的销毁方法,同时也作为资源化的预处理节约了工艺流程.铝合金回收是硬盘资源化的重点,除漆则是硬盘铝合金回收的关键环节,实验表明热除漆法能够很好地达到二次熔炼要求.半导体存储介质中的半导体材料、非金属材料和金属材料均是可回收资源,通过静电分选将三者加以分离是半导体存储介质资源化的关键技术,也是目前的研究重点.
