Circular Economy:  Resource Recovery, Recycle and Reuse

In the circular economy, the reuse of raw materials is optimized so that at the end of a product’s life cycle, many of the resources used to create it are recovered, recycled, and reused.

This is in contrast to a linear economy with a take-make-dispose system.

According to the Ellen Macarthur Foundation, “the circular economy vision and approach gives endless possibilities to create a thriving economy.”

This concept is applicable to the metals, mining and minerals processing industries, to name just a couple of the diverse industries that Micronics serves.

Electronics including laptop computers, mobile phones, lead-acid batteries, lithium-ion batteries (LIBs), and e-scraps from circuit boards are all areas that have high-value content that can be reused/recycled.

Nickel, zinc, copper, lead, cobalt, and manganese are just a few of the metals that are being recycled from diverse applications. For instance, cobalt, nickel, and manganese are key elements in cathodes (positive electrodes) in LIBs used in electric vehicles.

Liquid-Solid Separation & the Circular Economy

The circular economy has well-established needs for both recycling liquids and capturing solids such as precious metals for reuse. Filter presses are commonly used for dewatering & efficiently separating liquids and solids.

Micronics is an expert in liquid-solid separation using filter press technology under high slurry feed pressures. If you are interested in recovering, recycling, and reusing valuable metals, Micronics can help your team develop an application-specific filtration system tailored to your specific needs.

We are accustomed to working with many slurries and operating conditions. For instance, Micronics also has filter press expertise in the ready-mix concrete market, where there is a growing demand for reclamation/reuse of gravel, sand, and water.

How Can Pilot Testing Assist You with Optimum Filter Press Design for Your Circular Economy Application?

Unlike many other suppliers, Micronics’ sales personnel are based in the geographic territories we serve. Our territory sales engineers will visit your location and assist your team with pilot testing the slurries at the site if you so desire.  We understand that many such applications for reuse/recycle are proprietary and we will be happy to sign an NDA.

On-site pilot testing allows us to dial-in the filtration equipment or control needs for ultimately a better designed & supplied engineered filtration system.

Custom-Engineered Filter Presses for Your Specific Requirements

While we offer and stock standard filter presses – such as our popular 630mm and 800mm sizes available for quick shipping and deployment – the majority of Micronics Filter Presses are custom-engineered and tailored to your specific requirements. Our MicroPressTM is a 150mm bench-scale test press whereas the majority of our presses are in the 470mm to 1500mm or 1 to ~300 cubic foot capacity. The press pictured above is a Micronics 800mm filter press.

We also supply very larger presses such as our mining filter presses which may be 2000mm, or capacities up to 600 cubic ft., or greater.
