Sustainable fashion isn’t only about eco-friendly clothing; it’s also about eco-friendly production. As far as stone washing is concerned, pumice stone washing is the staple. However, it is not sustainable. On the other hand, HMS (Hand Made Stone) is an eco-friendly alternative. Through this blog, let’s look at the industry use of HMS and pumice stone and understand how HMS is way better both in terms of sustainability and efficiency.

The Industry Use of Pumice Stone and HMS: Explained
Environmental Impact of Pumice Stone in Stone Washing
Mining
The journey of denim’s environmental impact commences at the source – the pumice stone mines. Fortunately, pumice stone mining typically occurs through surface mining methods, which are relatively less invasive compared to other forms of mining. However, the extraction process still necessitates energy and resources, albeit to a lesser extent.
Transportation
The distance between mining sites and processing facilities, followed by the transportation of processed pumice to denim manufacturing facilities, incurs considerable energy expenditure and emissions. This transportation represents a significant contributor to the carbon footprint of pumice stone.
Storage
Pumice stone dissolves rapidly during washing processes which calls for a continuous substantial supply. This further exacerbates the need for expansive storage spaces. These storage requirements strain warehouse capacities and contribute to the environmental footprint of denim manufacturing.
Water Usage
As the stone dissolves during washing processes, it contaminates water with particles and contaminants, requiring higher volumes of water for thorough cleansing. This strains water resources.
Energy Usage
The traditional pumice stone washing process requires heated water. This consumes substantial energy, contributing to the overall carbon footprint of denim manufacturing.
Wastewater Systems
The rapid dissolution of pumice stone makes wastewater management difficult. The water gets laden with residues and contaminants, straining wastewater treatment plants’ operational efficiency. This further amplifies the environmental impact of denim production.
Earth Contamination
The waste generated from wastewater systems, saturated with contaminants from pumice stone and other elements used in denim washing, poses a risk of earth contamination. Disposal practices, such as burial, introduce foreign substances into the soil that potentially disrupt the natural balance of the environment and harm surrounding ecosystems.
Environmental Impact of HMS in Stone Washing
Mining
HMS skips the mining step altogether because it is made from pumice dust and organic polymers. In this way, HMS immediately diminishes its environmental impact in the beginning itself.
Transportation
Transportation is entirely circumvented in the case of HMS since there is no mining at all. This presents HMS stones as a more sustainable choice.
Storage
The durability of HMS is up to 60 times that of pumice stone. This efficiency results in less need for storage space and supply.
Water Usage
HMS needs 20% less per load. Also, HMS melts away up to 60 times slower than pumice stone. This shows water conservation aspects of HMS washing i.e., sustainable stone washing.
Energy Usage
HMS is compatible with cold water which eliminates energy-intensive heating during washing processes. This also reduces the overall carbon footprint of denim manufacturing.
Wastewater Systems
60 times durability means 60 times less water contamination. This alleviates the strain on wastewater treatment plants and fosters more responsible and efficient wastewater management practices within the industry.
Earth Contamination (No Sludge)
Unlike pumice stone, HMS creates no sludge at all, avoiding one of the biggest Earth haters.
Comparison of Water Efficiency
Water efficiency stands as a critical factor in evaluating the environmental impact of denim washing practices. Pumice stone washing processes typically require higher volumes of water due to the rapid dissolution of the stone during washing. In contrast, HMS offers notable water-saving advantages. With its slower dissolution rate compared to pumice stone, HMS can achieve a 15%-20% reduction in water usage compared to traditional pumice stone, making it a sustainable denim washing option. In addition, due to no dust left on the fabric after the stone washing, rinsing is not needed, unlike pumice stone washing.
Comparison of Storage Space Efficiency
Efficient storage space utilization optimizes logistics and operational efficiency within denim factories. Pumice stone, due to its rapid dissolution rate during washing processes, demands extensive storage space to accommodate the large quantities required for consistent production. On the other hand, HMS offers a revolutionary solution. With its exceptional durability—up to 60 times that of pumice stone—HMS requires significantly less storage space. In essence, HMS takes 60 to 100 times less storage space than pumice stone.
Comparison of Production Capacity
In denim manufacturing, production capacity and workforce efficiency are paramount for operational excellence. The durability of HMS translates into extended wear periods compared to pumice stone. While pumice stone requires frequent reloading during washing processes due to its rapid dissolution, HMS maintains its effectiveness for a much longer duration. This extended lifespan reduces the frequency of stone changes, resulting in fewer interruptions to the production process and increased overall production capacity.
Comparison of Stone Wear and Residue of HMS and Pumice Stone
A comparative analysis between HMS and pumice stone sheds light on their respective performance in terms of wear and residue, providing insights into their environmental impact. HMS, with its exceptional durability, undergoes wear at a substantially slower pace compared to traditional pumice stone. That is, it wears out just 1-3% in an hour. While pumice stone diminishes in size considerably after just one hour of use, HMS maintains its size and effectiveness for an extended period, often up to 60 times longer. Furthermore, unlike pumice stone, HMS creates no sludge at all, avoiding one of the biggest toxicities.
Conclusion
The adoption of HMS represents not only a strategic business decision but also a moral imperative in the pursuit of a more sustainable future for the fashion industry. By embracing innovation and sustainability, denim manufacturers can drive positive change and responsible fashion production.

Frequently Asked Questions (FAQs)
What is the difference between HMS and pumice stone in stone washing processes?
HMS is an eco-friendly alternative to pumice stone, made from pumice dust and organic polymers. It skips the mining step altogether which reduces its environmental impact from the beginning. On the other hand, pumice stone requires mining, transportation, and substantial water and energy usage during the washing process, adding to its environmental footprint.
How does HMS contribute to sustainability compared to pumice stone?
HMS offers several sustainability advantages over pumice stone. It requires no mining, reduces transportation needs, consumes less water (up to 20% less per load), operates with cold water, and generates no sludge. Its durability, up to 60 times that of pumice stone, results in less storage space required and fewer interruptions to the production process. These improve overall efficiency and reduce environmental impact.
What are the environmental implications of using pumice stone in denim manufacturing?
The environmental impact of pumice stone in denim manufacturing includes energy-intensive mining processes, transportation emissions, water contamination, high water usage during washing, significant storage space requirements, and the generation of sludge, which poses risks of earth contamination. These factors add to the overall carbon footprint and environmental strain of denim production.
How does HMS lead to water and energy efficiency in denim washing?
HMS offers notable water and energy efficiency advantages compared to pumice stone. Its slower dissolution rate during washing processes results in up to 20% less water usage per load. Furthermore, HMS is compatible with cold water which eliminates the need for energy-intensive heating during washing.
What are the implications of stone wear and residue in denim washing, and how do HMS and pumice stone compare?
The wear and residue of stones in denim washing processes impact both operational efficiency and environmental sustainability. HMS wears out at a significantly slower pace (just 1-3% in an hour) compared to pumice stone. Also, unlike pumice stone, HMS generates no sludge, further reducing its environmental harm. Out of HMS and pumice stone, the extended lifespan and absence of sludge make HMS a more environmentally friendly option for denim washing.
