Nowadays, almost every society is highly dependent on chips made out of thin silicon wafers. Semiconductor materials are the fundamental components of modern computing and all the systems that depend on them, from electrical circuits to cell phones.
In fact, the worldwide number of devices made using these materials each year now exceeds 1 trillion, and it’s only expected to grow. In this environment, the question of how we get rid of modern chips is more important than ever.
In this article, we’ll explore chip waste, how countries get rid of these harmful materials, and what alternatives there are for the years to come.
To dispose of metal chips, it’s necessary to consider the kind, quantity, size, and shape of them, in addition to the equipment, space, and rules available. A number of technologies and techniques are used to lessen the quantity of chip waste and its negative effects on the environment.
The problem is that most chip waste isn’t properly sorted out when disposed of, and there are no laws in place to ensure that. Moreover, the size of the yearly chip disposal makes it harder for countries to manage.
Silicon is a highly abundant material. In fact, it’s the second most available material in the earth’s crust, second only to oxygen. So, as you can imagine, running out of silicon to fabricate wafers hasn’t been a worry for manufacturers.
Perhaps as a result, chip waste and thin silicon have not been a concern up until now. According to the Global E-waste Monitor, 53.6 million metric tons of e-waste were produced in 2019. Merely 17.4% was formally recorded as appropriately gathered and repurposed.
This demonstrates how important it is for the semiconductor industry to adopt more sustainable practices. And as the world gets prepared for a potential chip shortage, the conversation of chip disposal becomes not only a sustainability issue but also a potential solution.
Chip recycling offers enormous potential for obtaining secondary raw materials (such as semiconductors). According to experts, unrecycled electronic waste may contain recoverable precious metals valued at $57 billion.
E-waste, waste made up of electronics that have been recycled, donated, or thrown away, is the fastest-growing waste stream in the world. To reduce that, chip recycling may be the key, contributing to cutting emissions from the extremely polluting synthesis and purification processes linked to virgin raw materials and minimizing hazardous materials in landfills.

Wafer recycling is usually difficult, costly, and polluting, but things are starting to change. A great deal of work has gone into creating efficient and sustainable processes that can be applied to a variety of semiconductor devices.
Recycling metal chips can also have several advantages, including financial savings from lower waste disposal and a reduction in raw material consumption and costs. Another way to make money is by selling recycled metal to scrap dealers or metal processors, who can melt it and use it to create new products.
Furthermore, recycling semiconductors can increase safety by lowering the risk of fire and injury and improving quality by minimizing contamination and oxidation.
Sorting and separating metal chips based on their type, grade, and alloy is crucial when recycling them; mixing different metals can lower their quality and value. Because of that, businesses willing to recycle their chips may need to make an investment in equipment, space, and labor, which can cause a downturn.
Chip recycling is still a possible revenue source for your business, though, if you can locate a trustworthy scrap dealer or metal processor who can provide a reasonable price and easy service.
To do so, research the market and compare different scrap dealers or metal processors in search of one that better adapts to your needs. In addition, the quantity, quality, and value of the recycled metal and metal chips should be kept counted for accounting and auditing purposes.
Although chip recycling isn’t a very popular topic, various organizations offer support for those who are willing to make the effort and manage their tech disposal in a more sustainable way.
For example, you can contact the Association for Manufacturing Technology (AMT) to learn more about chip disposal and recycling in machining. This organization offers support, information, and networking for organizations and individuals in the manufacturing industry. Additionally, it regularly publishes reports and guides on chip waste management and recycling.
The Institute of Scrap Recycling Industries (ISRI) provides tools and resources for buyers and sellers of scrap metal and represents the scrap recycling sector, highlighting its advantages for the economy and environment.
And lastly, the American Machinist is a website and magazine that provides up-to-date information on the machining industry's newest developments, trends, and technologies. It includes videos and articles about recycling and disposing of chips.
We live in a society that’s highly dependent on technology, and most of it relies on chips made out of thin silicon wafers. Because of that, it's crucial to wonder about the methods we have available to dispose of these potentially hazardous materials in more sustainable ways.
Recycling chips and silicon semiconductors is crucial to saving our planet, and it could also be the answer to the upcoming chip shortage. Whatever happens here at Wafer World, we’ll be attentive to industry developments. If you’re interested in learning more about our wafers, give us a call!
