Analysis of Sustainable Development Goals in the Article

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

• SDG 2: Zero Hunger

  The article connects to SDG 2 by focusing on sustainable agricultural practices to ensure food security. It discusses enhancing the health of broiler chickens, a major food source, through natural feed additives. The research aims to create “sustainable farming practices” that are “essential for ensuring food security and public health in the years to come.”

• SDG 3: Good Health and Well-being

  This goal is central to the article’s premise. The research proposes cello-oligosaccharides as a sustainable alternative to traditional antibiotics in farming, directly addressing the global health crisis of “rising antibiotic resistance,” which poses “serious threats to both animal and human health.” By promoting gut health in poultry, it also contributes to healthier food products for human consumption.

• SDG 9: Industry, Innovation, and Infrastructure

  The article highlights an “innovative approach” and a specific scientific technique (“sequential enzyme addition”) to create a value-added product from waste. This represents an upgrade in agricultural technology and industrial processes. The research itself is an example of “interdisciplinary collaboration” aimed at “groundbreaking discoveries that not only enhance food production but also create beneficial outcomes for the environment.”

• SDG 12: Responsible Consumption and Production

  SDG 12 is addressed through the core concept of a circular economy, described in the article as a “waste-to-value paradigm.” The study focuses on repurposing sugarcane bagasse, an “agricultural waste” and “byproduct of sugar refinement,” into a valuable bioactive compound. This approach directly supports the goal of reducing waste and making efficient use of resources.

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

1. Target 2.4 (under SDG 2)

   “By 2030, ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production…” The article directly supports this target by developing a method for “sustainable farming practices” in the broiler industry. The use of cello-oligosaccharides as a natural feed additive is a resilient agricultural practice that enhances animal health without relying on antibiotics, thereby contributing to a more sustainable food production system.

2. Target 3.d (under SDG 3)

   “Strengthen the capacity of all countries… for early warning, risk reduction and management of national and global health risks.” The research addresses the global health risk of antibiotic resistance. By providing a viable “sustainable antibiotic alternative,” the study contributes to the management and reduction of this significant public health threat originating from agricultural practices.

3. Target 9.4 (under SDG 9)

   “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 article’s focus on utilizing sugarcane bagasse demonstrates increased resource-use efficiency. The enzymatic process described is an environmentally sound technology that transforms an industrial byproduct into a high-value product, aligning with the goal of making industries more sustainable.

4. Target 12.5 (under SDG 12)

   “By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse.” The entire study is premised on this target. It presents a method to reuse and find value in “sugarcane bagasse, a byproduct… often overlooked and deemed waste.” This process is a clear example of reducing waste by repurposing it within the agricultural sector.
