Recovering Precious, Heavy, And Base Metals With Urban Mining

2019-06-20T16:29:03-07:00 June 20th, 2019|

Whether you’re aware of it or not, you are using a variety of base, precious, and heavy metals right now! You’re probably reading this on your phone or computer, which functions through the use of over 60 types of metals. When our devices become obsolete, urban mining provides a way to recover these valuable metals [...]

How Waste Is Turned Into Energy And Valuable Metals

2019-06-11T10:59:12-07:00 June 11th, 2019|

Many communities around the globe are using waste to power their homes. Instead of sending their trash to a landfill, it’s taken to a waste-to-energy facility where it is turned into electricity. As the waste releases energy, a byproduct called incinerator bottom ash (IBA) is created. This IBA contains precious and base metals which can [...]

The Resources In Our Cities

2019-05-23T10:54:33-07:00 May 23rd, 2019|

Our cities are full of resources. Roads, buildings, cars, electronics and even our trash can be a treasure trove of valuable materials. Using urban mining processes, we can recover and reuse these resources, which ultimately lessens our need to mine for virgin materials. At Sepro Urban Mining, we look at things a little differently. For [...]

Where Does All Your E-Waste Go?

2019-05-10T14:40:52-07:00 May 10th, 2019|

Electronic waste (e-waste) consisting of cellphones, laptops, and other electronics, is now the fastest growing waste stream in the world. Just under 50 million tons of e-waste was generated in 2018, and this number is expected to increase at a rate of 4-5% annually. Without the proper use of urban mining, e-waste is sent to [...]

What on Earth Is a Fine Slag Treatment Plant?

2019-04-23T13:36:22-07:00 April 23rd, 2019|

Incinerator bottom ash (IBA) is made up of particles that do not fully combust in waste-to-energy facilities. IBA often contains precious and heavy metals, which can be recovered and recycled when processed properly. Few IBA treatments provide effective recovery of fine metals. As such, current recovery rates are suboptimal and inefficient. Sepro’s Fine Slag Treatment [...]

Urban Mining And The Circular Economy

2019-04-10T15:29:50-07:00 April 10th, 2019|

If you’ve been reading our latest blog posts, you know that urban mining is an effective way to recover valuable elements from discarded materials. These sources include everything from TVs and cellphones to demolished buildings and other waste streams. Metals, along with many other resources, are non-renewable. This means that once we have harvested all [...]

Efficient Urban Mining And The Environment

2019-03-13T11:04:40-07:00 March 13th, 2019|

Cell phones, laptops, computers and other electronics generated over 47 million metric tons of waste (known as e-waste) in 2017 and this number is growing at a rate of 3-5% per year. By 2021, it is expected that over 51 million metric tons of e-waste will be generated globally. Unfortunately, most of this waste will [...]

The Technical Aspects Of Wet Processing Fine Incinerator Bottom Ash

2019-03-05T15:55:16-07:00 March 5th, 2019|

There are multiple ways to process incinerator bottom ash (IBA). This technical paper looks at the conventional "dry" method of processing IBA and compares it to the "wet" processing system before delving into Sepro's Fine Slag Treatment Plant (FSTP) which can increase the recovery of fine precious metals. For more information, click on the full [...]

The Urban Mining Effect

2019-02-26T14:47:34-07:00 February 26th, 2019|

Metal ores found in the Earth are a non-renewable resource. Once we have discovered and extracted every ounce of metal from our planet, the resource is depleted. From this perspective, mining has an ultimate end-date. For a world with an ever-increasing demand for products containing metal, this may seem like a disaster. However, recent developments [...]

What Is Urban Mining?

2019-04-16T14:51:28-07:00 February 12th, 2019|

The ever-increasing demand for rare earth elements and precious metals, paired with the push-for-greener technologies has given rise to a new method of mining called urban mining. In short, urban mining is the process of recovering compounds and elements from used products, buildings or waste. Sepro Urban Mining has the ability to maximize the [...]
