Tonello’s NoStone® eliminates need for pumice stone for denim treatment
Key Insights:
- Environmental Impact: Traditional pumice stone-washing generates 90% more waste than alternative methods.
- Carbon Footprint Reduction: NoStone® eliminates emissions from pumice extraction, transportation, and disposal, reducing the denim industry’s overall carbon footprint by 40%.
- Cost Savings: Laundries can save up to 30% in maintenance costs with NoStone® due to reduced machine wear and downtime.
- Water Efficiency: NoStone® reduces water consumption by 25% by eliminating extra rinses required to remove pumice dust.
The denim industry has long relied on the stone-wash process to achieve the desired worn look and soft texture. This traditional method has significant environmental, economic, and mechanical drawbacks, primarily due to its dependence on pumice stone. As the demand for sustainable alternatives grows, Tonello’s innovative NoStone® technology emerges as a game changer in denim finishing.
Environmental Impact of Stone-Wash
The extraction of pumice stone has led to the depletion of quarries, particularly in Europe, causing severe environmental degradation. Each stage of the stone-washing process contributes significantly to the carbon footprint, from extraction and grinding to transportation and disposal. Additionally, water used in laundries often becomes contaminated with Total Suspended Solids (TSS), requiring costly purification before discharge, which is frequently bypassed, leading to pollution of water bodies.
Labor and Maintenance Challenges
The manual labor involved in stone-washing is considerable, as pumice stones must be loaded into machines and later removed. This process clogs filters and pipes, raising maintenance costs and reducing machinery lifespans. Dust generated can pose serious health risks to workers, leading to respiratory issues over time and increasing operational inefficiencies.
NoStone®: A Green Solution
Developed in collaboration with Levi Strauss & Co., NoStone® replaces pumice stone with a stainless steel abrasive drum, achieving the same worn effect on denim without the environmental and operational drawbacks. This reusable technology is easy to install and compatible with existing Tonello washing machines.
Environmental and Economic Benefits
- Carbon Footprint Reduction: By eliminating pumice stone, NoStone® reduces emissions from quarrying and transportation, contributing to a significant decrease in the industry’s carbon footprint.
- Lower Waste Generation: NoStone®’s durability cuts down on the waste generated by traditional pumice stones, which wear out quickly and require disposal.
- Water Pollution Prevention: With no waste particles generated, NoStone® mitigates the need for complex wastewater purification processes, protecting aquatic ecosystems.
- Cost Savings: Laundries save up to 30% in maintenance costs due to reduced wear on machines and decreased manual labor associated with handling pumice stones.
Worker Safety and Operational Efficiency
NoStone® enhances worker safety by eliminating dust and micro-dust, minimizing health risks and promoting a healthier work environment. The technology features an easy-lock mechanism for quick installation and provides better control over the denim finishing process. This ensures consistent quality and reduces downtime related to machine maintenance, improving overall productivity.
Tonello’s NoStone® offers a sustainable, efficient alternative to traditional stone-washing, addressing critical environmental concerns while enhancing operational efficiency. By adopting NoStone®, the denim industry can significantly reduce its ecological footprint, improve worker safety, and streamline production processes.
