In plain terms, mining operations pertain to the set of activities that facilitate the exploration, production, and separation of certain desirable metals and minerals from their ores. With all the major day-to-day operations based on the availability of these minerals, the importance of the mining industry increases manifolds. Mining operations are dependent on several factors that pertain to the accurate estimation regarding the positioning and recovery of the reserves. Some of the key factors that help aid the decision relating to the type of the mining operations includes.

核电站产生的废物的处理尽可能延用运行废物处理系统，考虑到退役废物的废物类别及产生量与运行废物差异较大，可考虑增设必要的废物处理手段或扩大废物处理能力，是否新建废物处理设施应综合考虑是否有适宜场址、工期是否允许以及是否存在与退役无关且足够大的子项可进行改扩建等操作。文章以 M310 堆为例，估算了单机组退役可能的退役废物产生量，同时，为实现废物最小化的目标，提出了进行设计优化，严格运行管理、避免事故发生，严格进行废物分类，利用废物处理手段减少废物处置量和废物体积以及对材料再循环再利用等建议。    

Plastic recycling decreases the quantity of wastes that are being dumped into landfills and aids in transforming the wastes into lower or same grade plastic materials. These products are used across different sectors. A large proportion of the plastic that is procured for recycling is not suitable for recycling as most plastics used are semi-porous and absorb molecules of the stored material. The removal of these residues is tedious and additional treatments for the same can potentially alter the properties of the recycled plastics. Most recycled plastics are used to make lower grade products. These are hydrolyzed to a monomeric form and then purified and re-polymerized into food grade plastic.
