Circular Economy

SLS engages collaboratively with global clients to re-examine business models and to plan for continual evolution towards a circular economy model. Clients leverage our knowledge about disposition of retired electronic assets, managing their movement through reverse supply chains, and quantifying the carbon impact of these assets.

SLS works with clients to identify opportunities to reuse and redeploy equipment. This extends the useful life of IT equipment, avoiding the need to manufacture new products. We refurbish and remanufacture your data center and IT assets for resale and redeployment. Our parts recovery and reprogramming services play a key role in supplementing supply chain shortages for new product manufacturing, replacement, servicing and repair streams.

Reuse avoids the emissions associated with manufacturing new products, reduces reliance on raw materials, avoids landfill and can contribute to localizing supply chains. It make sense for your bottom line and your sustainability goals.


Recycling obsolete electronics diverts material from landfill or incineration. SLS invests in innovative technology to produce clean recyclables that can be used as a feedstock to replace virgin raw materials in making new products. Extracting more value from materials, through reuse and recycling, is a good economic decision and plays an important role in the circular economy.

New Sustainability Calculator for IT and Data Center Assets

Recognizing you manage what you measure, we have developed a sustainability calculator for measuring carbon savings by choosing to reuse and recycle electronics.

SLS’ Sustainability Calculator provides our clients with industry-leading environmental reporting when reusing, redeploying and recycling all types of IT equipment. The calculator enables clients to measure reduced Scope 3 emissions associated with reuse and recycling of IT assets.

The calculator is powered by manufacturers’ data on the most commonly used IT equipment, including laptops, servers, PCs, monitors, networking equipment and printers, in addition to our own proprietary processing information. Clients are able to calculate carbon avoided from their IT asset disposition program, which enables:

What is Reported?

Carbon avoided when reusing whole units and components, and recycling of IT equipment is reported from the calculator. In addition to tonnes of carbon avoided, we also provide carbon avoided equivalency metrics, which provide a user-friendly way to visualize the results.

The SLS Sustainability Calculator provides clients with transparent sustainability reporting suitable to contribute to corporate carbon accounting. Our robust and up-to-date data sets and transparent calculations provide proof points to withstand internal and external audits.

Learn how ITAD activities reduce Scope 3 emissions and contribute to carbon reduction calculations.

How It Was Built

The engine behind the calculator is independently sourced and verified and is regularly updated. It includes more product categories than others on the market, including a wide range of cloud materials. Energy consumption data is sourced by country, providing more accurate calculated results.

Benefits of Working with SLS

We provide accurate and complete quarterly reports to our clients, detailing carbon avoided by their current ITAD program. Because IT equipment continues to evolve, we recognize the importance of updating our calculator to stay in sync with the marketplace. We ensure that the information is current and relevant through regular maintenance and updates, including new product categories and the most current assay findings.

Reusing Assets Yields Significant Sustainability Gains

The new SLS Sustainability Calculator empowers our clients to quantify carbon emissions avoided, not only from recycling, but also from the reuse of IT assets, an important differentiator from most calculators available. This matters because compared to recycling, the reuse of electronics results in significantly higher carbon reduction.
