We often take them for granted, but fasteners are everywhere around us – in our cars, our furniture, and countless other everyday objects. It might not be something we usually think of and want, but it is something we really need. Fasteners play a critical role in our daily lives, and they can also play a significant role in sustainability. The fastener industry is experiencing rapid growth, particularly in North America, due to rapid development of other industries such as construction, auto, aerospace and the industrial sector. The projected growth from now to 2030 is about 4.7%. (1) With such rapid growth environmental impact cannot be ignored, given the significant role of manufacturing in the U.S. economy. The harmful impactHow could fasteners impact the environment? When considering the lifecycle of a single fastener, potential environmental harm can arise from the very beginning to the very end. Let’s start from day one with the extraction of materials for fastener manufacturing. Most fasteners are made from our well-known aluminum and steel because of their resistance to rust. According to research, the iron and steel industry is responsible for about 7% of gas emissions and 11% of CO2 emissions (2). Steel production is considered one of the major contributors to greenhouse gas emissions, primarily due to the use of coal in blast furnaces (3). Statistics are not great, are they? But that’s not the end. After getting materials we are moving forward to fastener production itself. First, the manufacturing process is energy-intensive, leading to high energy consumption and waste generation, including packaging and material waste. In addition to that we see considerable water usage. The next stage is transportation. There is no secret how harmful transportation, primarily fossil fuels, is for the environment as it contributes to air pollution and gas emission. And finally, the end of life. After their useful life, many fasteners end up in landfills. Worse yet, if the fastener is not of high quality, its short lifespan can lead to increased waste due to frequent replacement. Solutions Now that we've recognized the environmental impact of the fastener industry, it's crucial to explore solutions. Let's focus on improvements at each stage of the lifecycle. Stage one: extraction of the materials. At this stage, several solutions exist. Firstly, reusing existing fasteners is a simple yet effective approach. This not only conserves the planet's resources but also saves the company time and money, as material extraction is a lengthy and expensive process. Another solution, and a recent initiative, is moving towards plastic fasteners. One might question how plastic and sustainability can coexist in the same sentence. However, it takes fewer resources to manufacture plastic fasteners compared to metal ones. (4) Plastic fasteners are better suited for outdoor use as they are less susceptible to corrosion than other materials, leading to longer lifespans and reduced replacement needs. Additionally, they make constructions lighter, saving energy during transportation and contributing to lower carbon emissions. But what if none of those choices are available? Then there is always the option to use renewable energy in the extraction process. For example, instead of fossil gas, the company might use solar or wind power. Stage two: fastener manufacture. At this stage of production, manufacturers can try to implement reusable energy sources. One approach is adopting technologies like LED lighting and utilizing renewable energy sources such as solar or wind power. This can significantly reduce energy consumption for heating and electricity, thereby lowering the carbon footprint and overall environmental impact. A prime example is BUMAX, a Swedish high-strength stainless steel fastener manufacturer. The company has successfully reduced carbon emissions from heat by 62% since 2011 and continues to explore further improvements. (5) Another solution involves implementing new technologies. For instance, one of the latest innovations is CAD Software, which enables precise 3D modeling of fasteners with exact specifications. This reduces the need for physical prototypes, thereby saving energy and time. Furthermore, investing in longer-lasting fastener design is crucial. This leads to fewer replacements and less landfill waste. This approach not only impacts sustainability but also enhances the company's reputation and market position. Overall, these strategies align with the principles of lean manufacturing, a production philosophy that aims to minimize waste and maximize productivity. By optimizing resource utilization, companies can reduce costs while improving their environmental performance. Stage three: transportation. The easiest and most effective way to reduce a carbon footprint is to use local suppliers and work with local customers as much as possible. This minimizes delivery time, which in turn lowers energy consumption. Another approach is optimizing routes for drivers to improve efficiency, reducing wasted time and resources. Additionally, adopting reusable packaging and more sustainable materials is a crucial initiative. Right now, even paper packaging is not always the best choice, but there are many new innovations, such as seaweed-based packaging and packaging made from biodegradable materials, that can reduce potential harmful waste. As we live in this world, we must support nature and remain mindful of the impact we create—not only for ourselves but for future generations. We cannot take our Earth and its resources for granted, as everything has its limits.
Sustainability is a priority, not a choice in the 21st century. Now it affects a company's reputation and customer relationships. So being mindful about it and always trying to improve is crucial.
