The article discusses research in genetic selection and microbial symbiosis as ways to upgrade industrial processes for waste management, promoting sustainable and innovative industrialization.

• SDG 11: Sustainable Cities and Communities

  The article’s central theme of managing organic waste directly relates to making cities more sustainable. By processing food scraps and other organic materials, BSF larvae help reduce the volume of waste sent to landfills, which is a critical aspect of municipal waste management and reducing the environmental impact of cities.

• SDG 12: Responsible Consumption and Production

  This is the most prominent SDG in the article. The entire concept of waste valorization using BSF larvae aligns with circular economy principles. It focuses on reducing waste generation, recycling organic materials, and reusing them to create valuable products like animal feed and fertilizer, thus promoting sustainable consumption and production patterns.

• SDG 13: Climate Action

  The article mentions that the BSF larvae process “minimizes greenhouse gas emissions typically associated with waste decomposition in landfills.” By diverting organic waste from landfills, where it would produce methane (a potent greenhouse gas), this technology serves as a climate change mitigation strategy.

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

1. Target 2.4: Sustainable food production and resilient agricultural practices

   The article supports this target by describing how BSF larvae can convert waste into organic fertilizer that “enhances soil fertility” and “promotes sustainable agricultural practices,” which are essential for maintaining food security.

2. Target 8.4: Improve resource efficiency in consumption and production

   The process of waste valorization, which turns “what was once considered refuse into resources,” is a direct application of this target. It exemplifies decoupling economic growth from environmental degradation by creating value from waste.

3. Target 9.4: Upgrade infrastructure and industries for sustainability

   The article discusses “biotechnological innovations” and the need to standardize rearing conditions to scale up BSF technology for commercial applications. This represents an effort to adopt clean and environmentally sound technologies and processes in the waste management industry.
