Mass Balancing and Blockchain: Transparency Enabler in the Waste Management Landscape

Mass Balancing and Blockchain: Transparency Enabler in the Waste Management Landscape

Waste management is a complex and challenging task that requires coordination, transparency, and accountability among stakeholders such as producers, recyclers, and regulators. However, the lack of reliable data and information on the quantity, quality, and destination of waste streams continues to hinder efficiency and sustainability. Mass balancing in waste management, supported by blockchain, offers a technology-driven pathway to address these challenges.

How Mass Balancing Works

Mass balancing is a scientific method used to track the flow and transformation of materials across a supply chain. It ensures that input and output quantities match—helping trace the origin, quantity, and quality of materials while validating sustainability and circularity claims.

Why Blockchain Enhances Mass Balancing

Blockchain acts as a secure, transparent, and immutable ledger that records transactions and data across the waste ecosystem. When combined, the technologies offer:

• A tamper-proof platform for waste data collection and exchange

• Incentive models using tokens/certificates for reuse, recovery and recycling

• Privacy and control over data access for stakeholders

Adoption Challenges

Despite its promise, the widespread adoption of mass balancing and blockchain requires addressing:

• Technical barriers: scalability and interoperability

• Legal issues: data privacy and ownership

• Social dynamics: participation across formal and informal waste sectors

The Bigger Picture: Circular Economy Impact

Beyond managing specific waste categories, the integration of mass balancing and blockchain supports the creation of a collaborative circular ecosystem, enabling responsible resource use and stronger producer-recycler accountability.
