Failing to securely destroy data-bearing devices can lead to data breaches, regulatory fines, and reputational damage. Under the UK GDPR, EU GDPR and Data Protection Act 2018, businesses are legally required to ensure data is rendered completely irretrievable when it’s no longer needed.
This isn’t just an enterprise concern — SMEs, schools, charities and public sector organisations are all bound by the same regulations. Any organisation that stores personal or sensitive information must be able to prove that it has been securely destroyed.

Why Physical Shredding Is the Gold Standard
Unlike traditional wiping or degaussing methods, physical shredding destroys the hardware itself, leaving no possibility of data recovery. This is especially critical for SSDs, which store data across multiple memory chips in unpredictable patterns, making wiped drives vulnerable to data recovery.
For HDDs, degaussing can sometimes work, but many organisations still prefer shredding as the only method that guarantees complete destruction of both data and devices.
Recommended standards: Most businesses should shred to DIN 66399 H-5 or H-6 level (≤10mm particle size) to ensure data is fully unrecoverable.
How the Shredding Process Works
Secure drive shredding uses industrial machinery to reduce storage devices into tiny fragments, making data recovery impossible. The process is carefully controlled from start to finish:
1. Asset logging and collection
All drives are logged, tagged, and sealed in tamper-proof containers to create a complete chain of custody.
2. Secure transport to the shredding unit
Devices are either moved under supervision to an audited facility or destroyed directly on-site using mobile shredding units.
3. Industrial shredding and verification
High-torque machines crush, cut and pulverise the hardware into 2–40mm particles. For most organisations, DIN 66399 H-5 or H-6 (≤10mm) is recommended.
4. Certification and recycling
A Certificate of Destruction is issued for each asset, and the shredded material is contained and sent for certified recycling.
Why SSDs need extra care:
Because SSDs store data on non-magnetic flash memory rather than magnetic platters, they require finer particle shredding using specialist SSD shredders.
Legal and Compliance Considerations
While UK and EU data protection laws don’t name shredding specifically, they do require that data is destroyed beyond recovery. Failure to do so can be treated as non-compliance and result in penalties of up to 4% of annual global turnover — not to mention reputational damage and loss of customer trust.
A clear example of this risk came in 2020, when the ICO fined a London-based law firm £98,000 after old computer equipment containing unencrypted personal data was sold on eBay. Although the firm had attempted to wipe the drives, data was later recovered by the buyer, breaching the Data Protection Act 2018 and GDPR. The ICO highlighted that simply deleting files or reformatting drives is not sufficient — data must be irretrievable.
Certain sectors have even stricter requirements, including finance, healthcare, legal, and government contracts, where physical destruction is often mandated by certification or internal policy. Many organisations certified to ISO 27001, PCI DSS, or NIST 800-88 adopt shredding as their standard practice to ensure full compliance and mitigate legal risk.
On-Site vs Off-Site Shredding
Choosing between on-site and off-site shredding comes down to how much security oversight your organisation needs.
| On-Site Shredding | Off-Site Shredding | |
|---|---|---|
| Where it happens | At your premises, using a mobile shredding unit | At a secure, audited shredding facility |
| Security level | Maximum — devices are destroyed before leaving the site | High — strict chain-of-custody during transport |
| Chain of custody | Fully maintained on-site | Tracked via asset logs and sealed containers |
| Risk of data loss | Virtually none (no transport risk) | Very low (minor risk during transit) |
| Best for | Highly sensitive or regulated data (legal, finance, government) | Larger volumes or lower-risk data (general business use) |
| Cost efficiency | Typically higher cost | Typically more cost-effective |
In short:
Choose on-site shredding for maximum control and immediate peace of mind.
Choose off-site shredding for efficient, secure destruction of bulk or lower-risk drives.
What Happens After Shredding?
Responsible disposal does not end once the drives are destroyed. What happens next is just as important for compliance and sustainability.
After shredding, the remaining material — a mix of metals, plastics and electronic components — is collected and securely contained to prevent any data fragment leakage. It is then transported to authorised treatment facilities, where it is sorted to separate metals from plastics and refined to recover valuable raw materials such as gold, silver, copper, palladium and rare earth elements. Any residual waste is processed in full compliance with WEEE (Waste Electrical and Electronic Equipment) regulations and environmental permits.
💡 Did you know?
One tonne of discarded circuit boards can contain up to 100 times more gold than a tonne of mined ore, making secure recycling both environmentally and economically valuable.
This closed-loop approach ensures your organisation’s data-bearing assets are handled safely from start to finish. It not only reduces e-waste and the demand for new raw materials but also supports your corporate sustainability goals and ESG reporting, giving you a full audit trail to demonstrate responsible IT asset disposal.
How to Choose the Right ITAD Provider
Choosing the right partner is crucial to protecting your data and proving compliance. Look for an ITAD provider with ISO 27001-certified facilities, full GDPR and WEEE compliance, and the ability to issue Certificates of Destruction for every asset processed. They should also provide detailed asset logging with serial number tracking, and ideally offer the option of secure on-site shredding using mobile units.
Secure ITAD has been trusted by organisations across the UK and Europe to handle data-bearing devices safely, securely and sustainably, providing complete audit trails and expert advice to keep businesses compliant.
Don’t Let Old Drives Become a New Risk
Unsecured data doesn’t disappear when you hit delete. Every forgotten hard drive or SSD left in storage could become a data breach — and a serious compliance liability.
Shredding your end-of-life drives is the only way to guarantee they can never be recovered, and it proves your commitment to protecting the people whose data you hold.
If you are unsure whether your current IT asset disposal policy is strong enough, now is the time to review it. Our team can guide you through the process and provide full peace of mind.
