Digital waste traceability systems (blockchain)

Digital waste traceability systems use technologies such as blockchain and the Internet of Things (IoT) to record every movement of a waste stream, from generation to final treatment, in a secure and transparent way. They improve operational efficiency, help combat fraud and make it easier to audit the chain of custody, strengthening the traceability of waste required by law.

How blockchain fits in

A blockchain is a distributed ledger in which each record holds verified information such as waste type, weight, carrier, destination and date. Each entry is validated cryptographically and is very difficult to alter retroactively, which helps guarantee the integrity of the data. This makes blockchain a promising, though still emerging, complement to official traceability systems rather than a replacement for them.

Integration with IoT and data analytics

Connecting traceability platforms to IoT sensors allows information such as location, volume or temperature to be updated in near real time. Analysing this data helps operators anticipate incidents and plan more efficient collection routes.

Key benefits

• Greater transparency across the chain of custody.
• Reduced risk of document falsification.
• Fewer administrative errors.
• Easier, partly automated regulatory compliance.

Typical applications

• Control of cross-border waste shipments.
• Tracking of industrial hazardous waste.
• Tracking of high-value recyclable materials and electronic waste (WEEE).
• Digital certification for environmental audits.

The regulatory context in the EU

Digitalisation of waste tracking is becoming mandatory in Europe. Under the revised EU Waste Shipment Regulation, the Digital Waste Shipment System (DIWASS) went live on 21 May 2026, requiring information and documents on waste movements between EU Member States to be exchanged electronically through a single platform, replacing paper-based procedures. In Spain, cross-border and domestic movements are governed by rules such as Royal Decree 553/2020 on waste shipments.

Challenges

• Interoperability between public and private systems.
• Upfront implementation costs.
• Training and technology adoption, especially in the public sector.

As these tools mature, waste management is moving towards more transparent, data-driven governance in which authorities, companies and citizens can rely on trustworthy information. This also feeds into ESG reporting on waste and the wider circular economy. At Manglai we help organisations measure their environmental impact and report on waste and circularity.
