Analysis of Sustainable Development Goals (SDGs) in the Article

1. Which SDGs are addressed or connected to the issues highlighted in the article?

• SDG 6: Clean Water and Sanitation

  The article’s primary focus is on algae-based wastewater treatment, which directly addresses the need for clean water and effective sanitation. It discusses methods for purifying industrial, municipal, and agricultural wastewater to combat “global water scarcity and environmental degradation.”

• SDG 9: Industry, Innovation, and Infrastructure

  The text highlights “recent innovations” and “ongoing R&D” in wastewater treatment, such as “microalgae-bacteria consortia” and “vertical conveyor belt systems.” It also mentions the development of “sustainable water infrastructure” projects in Asia, which aligns with the goal of building resilient and sustainable infrastructure through technological upgrades.

• SDG 11: Sustainable Cities and Communities

  The article points to the application of these technologies in addressing “large-scale urban wastewater challenges.” The mention of projects in major Asian hubs like Singapore, China, and the Philippines to manage “municipal” wastewater connects directly to making cities more sustainable by improving waste management.

• SDG 12: Responsible Consumption and Production

  The concept of a “circular water economy” is central to the article. The process not only purifies water but also transforms waste into “valuable byproducts such as biofuels, animal feed, and organic fertilizers.” This promotes sustainable production patterns by reducing waste and reusing resources.

• SDG 2: Zero Hunger

  The article mentions that the byproducts of algae-based treatment include “animal feed” and “organic fertilizers.” These products support sustainable agriculture, which is a key component of achieving zero hunger and promoting food security.

• SDG 13: Climate Action

  The article notes that algae-based fertilizers are a “low-carbon alternative to synthetic options.” By providing an eco-friendly substitute for energy-intensive synthetic fertilizers, this technology contributes to mitigating climate change.

2. What specific targets under those SDGs can be identified based on the article’s content?

1. Target 6.3: By 2030, improve water quality by reducing pollution… halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally.

   The article directly supports this target by describing technologies that “remove pollutants such as nitrogen, phosphorus, heavy metals, and organic matter” from wastewater and facilitate “water reuse projects.”

2. Target 9.4: By 2030, upgrade infrastructure and retrofit industries to make them sustainable, with increased resource-use efficiency and greater adoption of clean and environmentally sound technologies.

   The development of “cost-effective and eco-friendly alternatives” that can slash “energy use by up to 90%” and the implementation of “sustainable water infrastructure” projects are direct examples of actions toward this target.

3. Target 11.6: By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to… municipal and other waste management.

   The article’s focus on treating “municipal” wastewater to solve “large-scale urban wastewater challenges” in cities across the Asia-Pacific region aligns with this target.

4. Target 12.5: By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse.

   The technology exemplifies this target by creating a “circular water economy” where wastewater is not discarded but is recycled, and the resulting algal biomass is reused to create valuable byproducts, thus reducing overall waste.

5. Target 2.4: By 2030, ensure sustainable food production systems and implement resilient agricultural practices…

   The production of “organic fertilizers” and “animal feed” from the treatment process contributes to more sustainable agricultural systems by providing alternatives to synthetic products and creating value from waste streams.

3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?

1. Reduction in Pollutants: The article explicitly states that the technology removes “nitrogen, phosphorus, heavy metals, and organic matter.” Measuring the concentration of these pollutants before and after treatment serves as a direct indicator of water quality improvement (Target 6.3).
2. Energy Efficiency: The mention of a new technology that “slashes energy use by up to 90% compared to conventional aeration methods” is a quantifiable indicator of increased resource-use efficiency in industrial processes (Target 9.4).
3. Market Growth and Adoption: The projection of the market growing from “US$ 2.65 billion in 2024” to “US$ 4.19 billion by 2032” at a “CAGR of 5.89%” indicates the rate of adoption of this sustainable technology, which can be used as a proxy for progress in treating wastewater (Targets 6.3 and 9.4).
4. Generation of Byproducts: The creation of “biofuels, animal feed, and organic fertilizers” is an indicator of progress towards a circular economy and waste reduction. The volume of these byproducts can be measured to track progress (Target 12.5).
5. Investment in Sustainable Infrastructure: The launch of “algae-focused water reuse projects in Singapore, China, and the Philippines” by SUEZ is a qualitative indicator of investment and commitment to sustainable urban infrastructure (Target 11.6).
