Sustainable practices and eco efficiency in polluting and non-polluting manufacturing firms
This study utilizes PLS-SEM to demonstrate that while eco-design enhances eco-efficiency across all manufacturing firms, sustainable materials management yields significantly greater benefits in polluting industries, highlighting the need for sector-specific sustainability strategies.

Imagine a factory as a giant kitchen. Some kitchens cook with very messy, smelly, and toxic ingredients (like a chemical plant), while others cook with cleaner, safer ingredients (like a bakery or a furniture maker). This study asks a simple question: Does having a "green mindset" actually help these kitchens save money and reduce waste, or is it just for show?
The researchers looked at 300 Spanish manufacturing companies (the "kitchens") to see how three specific things work together:
- Green Mindset (Sustainability Orientation): How much the bosses say they care about the planet.
- Green Recipes (Eco-design): Designing products so they are easy to fix, reuse, or recycle.
- Smart Shopping (Sustainable Materials Management): Choosing ingredients (materials) that are durable, easy to separate, and recyclable.
Here is the breakdown of what they found, using simple analogies:
1. The "Green Mindset" Doesn't Always Change the Menu
The study found that just because a boss cares about the environment (Green Mindset), it doesn't automatically mean they will change how they design their products (Eco-design).
- The Analogy: It's like a chef who loves nature and wants to save the trees, but they don't automatically know how to change their recipe book to use less water. The intention is there, but the technical skill or specific plan to change the design is missing. The study says the "Green Mindset" needs a middleman to actually get things done.
2. "Smart Shopping" is the Missing Link
The study found that the "Green Mindset" does successfully lead to "Smart Shopping" (choosing better materials), but only for the messy kitchens (polluting firms).
- The Analogy: For the factories that create a lot of pollution, the pressure to be "green" makes them very careful about what raw materials they buy. They start buying materials that are easier to recycle or last longer. However, for the cleaner factories, this pressure doesn't seem to change their shopping habits as much.
3. "Green Recipes" Work for Everyone
The most consistent finding was that Eco-design (Green Recipes) always leads to better results, no matter what kind of factory you run.
- The Analogy: Whether you run a chemical plant or a bakery, if you design your product to be easy to take apart and reuse, you will save money and help the planet. This is a universal rule. It's like saying, "If you build a house with windows that open easily, it's easier to clean and ventilate, regardless of whether the house is in a city or the countryside."
4. The Big Difference: How "Smart Shopping" Helps
This is the most surprising part of the study. The researchers found that Smart Shopping (Sustainable Materials Management) helped the cleaner factories become more efficient, but it didn't seem to help the messy factories in the same way.
- The Analogy:
- For the Clean Factory (Non-polluting): They have the freedom to experiment. When they buy better materials, they can immediately use them to make their whole operation faster and cheaper. It's like a gourmet chef who buys fresh, high-quality ingredients and immediately creates a more efficient, delicious meal.
- For the Messy Factory (Polluting): They are often forced to buy specific materials just to follow the law or avoid fines. They might buy "green" materials, but they are doing it just to check a box for the regulators. It's like a chef forced to buy a specific type of flour by the health inspector; they buy it, but it doesn't necessarily make their cooking process more efficient—it just keeps them out of trouble.
The Bottom Line
The paper concludes that you can't use a "one-size-fits-all" approach to saving the planet in business.
- For Polluting Firms: Their "Green Mindset" gets them to buy better materials, but they need to figure out how to turn that into actual efficiency gains, rather than just doing it to follow the rules.
- For Non-Polluting Firms: Buying better materials is a direct path to saving money and being more efficient.
- For Everyone: Designing products to be reused and recycled (Eco-design) is the golden ticket that works for everyone, everywhere.
In short, caring about the environment is a good start, but to actually save money and the planet, you need to translate that care into specific design choices and material choices that fit your specific type of business.
