Circular Economy in IT – Principles, System Logic, and Practical Relevance
Circular Economy describes a fundamental shift in resource management. Instead of producing, using, and disposing of products linearly, the model aims to keep materials, components, and value creation in circulation for as long as possible. The decisive factor is not a single process, but the consistent organization of entire systems.
For IT, this approach is particularly relevant. Electronic devices represent a comparatively small share of global waste in terms of quantity, yet they contain a disproportionately high share of valuable and sometimes critical raw materials such as copper, cobalt, or rare earth elements. The complexity lies in the details: a smartphone can contain up to 50 different metals. In 2022, 62 billion kg of electronic waste were generated worldwide; only 22.3% were formally collected and recycled in an environmentally sound manner. Since 2010, e-waste has increased from 34 to 62 billion kg, while documented formal collection and recycling only grew from 8 to 13.8 billion kg – meaning the growth of the waste stream far outpaces its recovery. A significant portion of material and economic value is lost in the process.
From Linear to Circular IT Models
Traditional IT procurement often follows a linear logic: devices are purchased, used, and replaced at fixed cycles. This approach simplifies planning and processes but overlooks the fact that hardware does not lose its value at the end of first use.
Circular Economy replaces this perspective with a circular model. IT hardware is not primarily considered a consumable but as an asset that can be used, maintained, and passed on over multiple usage phases. The focus shifts from rapid replacement to value retention and system efficiency.
The Central Sequence of Circular Economy
A functional circular model follows a clear prioritization. This logic also aligns with the waste hierarchy in the European regulatory framework: prevention and reuse take precedence over recycling, while disposal is the last resort.
For IT, the prioritization is particularly important:
1. Use before replacement
Devices are used as long as they meet functional, security, and ergonomic requirements. Replacement decisions are based on actual need and condition, not rigid schedules.
Note: “As long as possible” is not an end in itself. Practical limits usually arise from security/OS support, compatibility requirements, performance profiles, and repairability. Circular Economy thus also means defining clear criteria for when prolonging use is sensible—and when replacement (including regulated secondary use) is the better option.
2. Repair before replacement
Repair is not an exception but a central element of circular systems. Early maintenance preserves functionality and device condition, preventing unnecessary value loss.
3. Reuse before recycling
Devices returned from first use can be checked, refurbished, securely and traceably data-wiped, and redeployed or resold. This keeps product value in the system.
4. Recycling as the last stage
Recycling is necessary but the last option in the cycle. It only occurs when reuse is no longer economically or technically feasible.
This sequence is crucial. If it is reversed, the circular economy is reduced to waste treatment and fails to fulfil its actual purpose.
Circular Economy as a System, Not a Single Measure
A common misconception is to reduce Circular Economy to isolated activities such as refurbishment or recycling. True impact emerges only when the entire device lifecycle is considered and managed.
This includes:
- Transparency over inventory, usage, and condition
- Clear criteria for repair, reuse, and replacement
- Traceable quality levels for reused devices
- Documented processes for return and end-of-life
- Secure and documented data deletion as a prerequisite for any reuse
Without this systematics, circular economy remains fragmented and difficult to control.
Short Practical Example (Lifecycle Flow)
A device returning from first use is not automatically “retired” but follows a standardized process: Return → Condition Check → Data Wipe → Possible Repair → Grading → Decision Path (Re-deployment, Spare Pool, Secondary Market, Recycling). The leverage is not in a single step, but in the consistent decision-making system and its continuity.
Measurability at System Level
The impact of Circular Economy is less about individual device metrics and more about the efficiency of entire systems. Relevant indicators include:
- Reuse rate (share of reused devices relative to new devices)
- Average usage duration per device category (including multiple usage phases)
- Repair rate (how many devices are refurbished instead of replaced)
- Grading distribution (quality of returns)
- Time-to-return (how quickly devices re-enter the process)
- Share of traceably documented end-of-life cases
Many IT losses do not result from technical defects but from organizational gaps: lack of transparency, rigid replacement logic, or unclear return processes. Circular Economy addresses precisely these systemic inefficiencies.
Circular Economy and Sustainability
Circular Economy is closely related to sustainability but is not identical to it. While sustainability often focuses on emissions, energy consumption, and environmental impact, Circular Economy provides the structural logic to reduce resource use permanently.
In IT, circular economy forms the foundation for achieving ecological goals over the long term. Sustainability is not considered in isolation but emerges as a result of a functioning circular system.
Economic Perspective
Besides ecological effects, Circular Economy has a clear economic dimension. Hardware that is used longer, repaired, and reused retains its value. At the same time, dependence on short-term procurement and volatile supply markets decreases.
Circular IT models improve:
- Investment planning
- Use of existing assets
- Control over residual value and end-of-life risks
Thus, circular economy becomes an instrument for stability and resilience, not just environmental relief.
Conclusion
Circular Economy in IT is not a trend or marketing concept. It is a structural model that fundamentally changes hardware management. What matters is not whether Circular Economy is discussed, but whether it is thought of and implemented as a system.
Companies that consciously manage use, repair, reuse, and recovery reduce resource losses, preserve value creation, and create transparency across the entire IT lifecycle.
Transition to Sustainability Perspective
Circular Economy defines the structural framework to keep resources, materials, and value creation in the system as long as possible. This is especially relevant in IT: in 2022, 62 billion kg of electronic waste were generated worldwide; only 22.3% were formally collected and recycled. At the same time, electronics contain a disproportionately high share of critical raw materials—a smartphone can contain up to 50 different metals.
How these circular principles can be implemented in operational IT and linked to measurable impact is demonstrated in the article on Sustainability im DaaS through concrete lifecycle approaches.
