Overview - ISO/TR 24217-2:2021 (Fine bubble technology & SDGs)
ISO/TR 24217-2:2021 is a technical report that provides guidelines for linking fine bubble technology applications to the United Nations Sustainable Development Goals (SDGs). It helps suppliers, document writers and stakeholders identify where fine bubble systems (compact, air–water based solutions) can contribute to specific SDG targets and how to present that contribution clearly to users, investors and regulators.
Key topics and technical focus
- Scope and purpose - Guidance for suppliers to show which parts of the SDGs their fine bubble technologies can support, and for writers to assess SDG contributions of related documents.
- Actors and stakeholders - Identification of partners and stakeholder groups (suppliers, users, communities, vulnerable groups) that can be affected by or benefit from fine bubble applications.
- Identifying SDG elements - Methods to select key SDG elements relevant to fine bubble technologies using sources such as safety data sheets, risk studies, sustainability reports and stakeholder input.
- Assignment of SDGs - Procedures to map specific applications of fine bubble technologies to relevant SDGs (see Annex A examples).
- Technical principles & measurement - References general measurement principles and categorization of fine bubbles (normative references to ISO 20480‑1 and ISO 20480‑2) to support objective claims.
- Review and revision - Guidance on documenting, reviewing and updating claims and evidence linking applications to SDGs.
- Evidence and evaluation - Informative annexes (B and C) provide example evaluation parameters and comparison data to substantiate SDG contribution claims.
Practical applications and who uses this standard
- Manufacturers and suppliers - To demonstrate how products (water treatment modules, cleaning systems, agricultural/aquaculture enhancers) align with SDGs for marketing, procurement and investment cases.
- Standards writers and technical authors - To assess and document SDG relevance of technical documents and product literature.
- Investors and banks - To evaluate SDG-linked investment opportunities and to verify sustainability claims.
- Policy makers, consultants and end users - To understand environmental, social and economic benefits (e.g., clean water, energy efficiency, sustainable food production) that fine bubble technologies can deliver.
