testing su pelle e cuoio - White Lab

White Lab created an integrated dedicated package of testing, consultancy and services for the companies operating in the tanning industry.

In addition to testing skin matrices, we offer environmental testing and consultancy services, consultancy on occupational safety and hygiene and on the construction of industrial waste water treatment and/or recovery plants.

For the companies operating in the tanning industry, White Lab offers a wide range of chemical and physical testing on skin and leather, in line with applicable Italian, European and international regulations and standards. Our team of experts assists the customer in choosing the appropriate testing strategy, ensuring high data quality and speed of execution.

With a specific consultancy service, we support companies in managing the requirements imposed by local, national, and supranational regulations and throughout the whole process to obtain and maintain the most important industry certifications (LWG, INDITEX, etc.).

We are also aware that each manufacturing sector has its specific environmental needs, therefore we tailor a wide range of accredited services to the needs of each customer in this industry, we support the customer throughout the whole process to obtain the relevant certifications and authorisations (AUA, AIA) and we ensure that each matrix (water, land, waste, air) complies with current laws and regulations.

Thanks to the versatility of the skills in its laboratories, White Lab can support its customers even with occupational safety and hygiene in compliance with Italian Legislative Decree No 81/08. The available services are: indoor monitoring of chemical, physical, and microbiological agents, risk evaluation, safety (POS), Operations Plan, Safety and Coordination Plan (PSC), and drafting of internal procedures.


The industrial process water management, treatment and recovery will increasingly have to meet the principles of environmental sustainability and reduction in ecological footprint.

Thanks to the most modern technologies on the market, White Lab gives its customers an exclusive service for the construction of waste water purification plants to allow the discharge into the surface water body or the sewers and of water recovery plants for the reintroduction of water in the production cycle, with a consequent substantial reduction of discharges, thus achieving results spending less.

The service for tanning companies is tailored and optimised for their specific industry needs and, in particular, for the treatment of waste water with high sulphate and chloride content.

Thanks to a highly-trained and constantly updated multidisciplinary team operating in synergy, White Lab Laboratories offer integrated packages of consultancy and testing services tailor-made for any customer type.
