The conventional use of pumice stones has shaped the industry of stone washing for decades. However, with a growing awareness of environmental impact, a new era ushers in — the earthy advent of Hand Made Stone (HMS). This eco-friendly alternative challenges the status quo and offers an environment-friendly pathway for denim manufacturing. So HMS Washing is here to uncover the artistry behind HMS, its creator Yavuz Baykan, and the transformative effects it brings to the denim industry’s ecological footprint.


HMS: The Fulcrum of Sustainable Stone Washing

Yavuz Baykan: The Man Behind HMS

The HMS revolution is led by Yavuz Baykan, a visionary whose journey reverberates with sustainability and innovation. Graduating from Ankara University, Faculty of Agriculture, Baykan’s impact spans over three decades. From his role as the factory manager in the establishment of Baykan Moda Lotus Jeans to his tenure as the General Manager of Baykan Moda, he has consistently pioneered eco-friendly practices. Notably, his engineering background resulted in the development of various chemicals and tools, including those for denim washing.

The turning point came after a five-year-long research and development phase between 2012-2017. In 2020, Baykan’s dedication bore fruit as the patent for HMS was approved. Since then, he has devoted himself entirely to advancing this earth-loving innovation. Baykan’s journey exemplifies a commitment to pushing the boundaries of sustainable practices in the denim industry.


HMS: The Sustainable Denim Washing

The quintessence of HMS lies in its composition — a fusion of pumice dust and organic polymers. This unique blend not only serves the purpose of denim washing but also addresses environmental concerns, setting HMS on a trajectory towards environment-friendly denim production.

Zero Discharge of Hazardous Chemicals (ZDHC)

Adherence to Zero Discharge of Hazardous Chemicals (ZDHC) guidelines eliminates harmful substances from the manufacturing process. By implementing ZDHC’s Manufacturing Restricted Substances List and Chemical Management System, HMS ensures that the chemicals used are safe for the environment and comply with global standards.

Environment Impact Measurement (EIM)

The transparency initiative continues with HMS’ listing on the Environment Impact Measurement (EIM) tool. This software assesses environmental impact across water and energy consumption, chemical product usage, and worker health. The low impact rating has been achieved by 100% of the HMS collection!

Effluent Treatment Plants (ETPs)

Effluent Treatment Plants (ETPs) are integrated into HMS production for efficient water management. In essence, our company focuses on water conservation, efficient water use, and recycling. This highlights the holistic approach towards minimizing environmental impact.


How HMS Provides Sustainable Stone Washing?


Unlike the conventional process of mining pumice stones, HMS takes a groundbreaking leap by entirely skipping this environmentally impactful step. This exemplifies HMS’ commitment to a zero-environmental impact approach.


Transportation, often a significant contributor to the environmental cost, is also bypassed in the case of HMS. The elimination of the need to transport HMS from mining sites to denim factories further enhances its eco-friendly profile.


Within denim factories, the adoption of HMS heralds a paradigm shift in various operational facets. Traditional storage demands for pumice stones are characterized by their rapid melting, necessitating expansive spaces. Conversely, the exceptional durability of HMS, up to 60 times more than pumice, revolutionizes storage requirements.

Water and Energy Usage

The slower melting rate of HMS, combined with a 20% reduction in water usage per load, represents a significant departure from the water-intensive nature of pumice stone washing. Furthermore, the adoption of cold water usage in HMS processes puts an end to energy-intensive heating.

Wastewater Systems

The impact on wastewater systems is equally profound. Pumice stones, with their rapid contamination of water, strain these systems. The 60 times slower melting rate of HMS points to less water contamination. This not only eases the burden on wastewater systems but also contributes to a more manageable water treatment process.

Earth Contamination

Waste from pumice stone-contaminated wastewater systems is typically buried which causes harm to the surrounding environment. In the case of HMS, its recyclability allows for the reuse of sludge from wastewater systems to remake HMS. This closed-loop system reduces earth contamination.

Size and Melting Rate

HMS, with its larger size and slower melting rate, extends the longevity of the stone and also reduces residue, particularly in shorter stone washes. This reduces the need for rinsing after washes.

Shipping Costs and Carbon Footprint

A metric ton of HMS can wash up to 72,000 garments, a capacity 60 to 100 times higher than conventional stones. This efficiency leads to a drastic reduction in shipping requirements. Instead of multiple containers of pumice, a single container of HMS can achieve the same result!

In a nutshell, the narrative shifts from traditional practices to an envisioning of a greener future. The benefits of HMS resonate across environmental, operational, and logistical dimensions that make way for eco-friendly denim manufacturing. Let HMS be a guiding light — a reminder that eco-friendly technologies and processes are not just choices; they are imperative steps towards a greener, cleaner, and guilt-free future for the denim industry.

Frequently Asked Questions (FAQs)

What makes Hand Made Stone (HMS) a sustainable alternative to pumice stone in stone washing?

HMS is an eco-friendly alternative due to its composition of pumice dust blended with organic polymers. Unlike traditional pumice stones, HMS is recyclable. Thus, it eliminates pollutive sludge, and significantly reduces water and energy consumption in the denim washing process.

How does HMS contribute to reducing the environmental impact of stone washing?

HMS reduces environmental impact by requiring up to 60 times less storage space than traditional pumice stones, lessening water contamination with a slower melting rate, and offering recyclability that transforms waste from wastewater systems into new HMS, thereby reducing earth contamination.

What advantages does HMS offer in terms of logistics and shipping?

The efficiency of HMS allows one metric ton to wash up to 72,000 garments. This reduces shipping requirements by 60 to 100 times compared to conventional stones. Consequently, shipping costs and the associated carbon footprint decrease.

How does HMS align with eco-friendly practices and transparency in denim manufacturing?

HMS incorporates upcycled pumice dust, follows Zero Discharge of Hazardous Chemicals (ZDHC) guidelines, and is listed on the Environment Impact Measurement (EIM) tool for transparency. These practices give rise to a closed-loop system, minimal waste, and adherence to global sustainability standards.

What role does Yavuz Baykan play in the development and promotion of HMS?

Yavuz Baykan, with an extensive background in sustainable innovation, played a crucial role in the development of HMS — the sustainable stone washing. From patent approval in 2020 to complete devotion, Baykan’s journey is a metaphor for advanced eco-friendly technologies and practices in the denim industry.
