How is Metal Recycled?
There is some variance in how metal is recycled. It may have to do with the type of metal used or the processes used by various waste recycling services in Denver CO. While there may be some differences here and there, it’s possible to outline the basic process in a way that everyone can understand. Here are the basic steps involved.
*Collection - Metal objects are collected and transported to a recycling center. From automobiles to household appliances, they are sold for scrap, sometimes crushed, and then delivered to a recycling facility.
*Sorting – This step focuses on segregating different metals used in the discarded items. At times, this is done manually. Other facilities may make use of automated equipment that can sort the materials based on the details. Tools like sensors or magnets may be utilized to quickly sort materials while saving time and labor.
The sorting may include one step more than dividing different kinds of metals. In some cases, separating metals that are relatively clean from those that need a lot of cleaning may be part of the process. It’s true that eventually, all the scrap will have to be cleaned; it’s just that some scrap may need deeper cleaning than the rest.
*Processing – Processing typically means breaking down the metal. Shredding is the most common way to do this. By shredding the metal into smaller and more manageable pieces, it prepares the metal for what is to come next. This also helps to decrease the amount of energy needed to continue preparing the metal for some future use.
*Melting – After shredding, melting in a furnace makes it possible to create metal that can be easily manipulated and shaped for future purposes. This particular step is one that requires more energy than the others. However, the energy expended in this step is still considerably less than the energy it would take to smelt and prepare raw materials for use. Different types of
furnaces are often used for reclaiming various metals. Besides, the temperatures used in the furnaces will vary, based on the type of metal involved. The actual process may take no more than a few minutes, although it may require hours when melting down certain metals.
*Purification – Purifying the reclaimed metal ensures that the quality is higher and that there’s nothing present that would interfere with the strength and durability of the recycled product. During this stage, all contaminants are removed. This results in a metal that is of the same quality as that made using raw materials. It’s not unusual for electrolysis to be used as part of
the purification process.
*Solidifying – Once the purification process is completed, the metal is shaped and cooled into the shape that is most common for that particular product. In some cases, that shape may be in bars. At other times, it may be sheets. The point is to prepare the metal for conveyance to the entity that will eventually put it to good use. Attention to the shape will aid in being able to ship the finished materials with relative ease.
*Shipping and Delivering the Recycled Metal – After the solidification process is completed and the metal is thoroughly cooled, it’s ready to be used in the creation of new goods. The recycled metal can be used to fill pending orders for everything from construction materials to the manufacturing of new metal objects. Based on the type of metal required as well as the amount, the material is prepared for shipment and ultimately delivered to a production facility where it can be made into whatever is required.
