At Sinus the future is built with more than one side and more than one vision.

Differentiation and quality were the stimulus to create Sinus, a partnership of two companies - Simaca and Eduardo & Gaspar.

Sinus results from the partnership of two companies – Simaca, a nationally and internationally well-known company as a supplier of natural leather, and Eduardo & Gaspar, a company with 80 years legacy of know-how and equipment from the former “Casa das Luvas”. Combining the best skills of both and developing ecological activity in the tanning industry, especially oriented for footwear, Sinus was born with the aim of promoting sustainable practices accordingly with the highest international standards.

So, meeting new industry challenges and consumer demands, Sinus presents a new and greener solution for for the leather sector. Throughout R&D projects, as well as constant upgrade of manufacturing processes and also in a close relationship with the Design, Sinus launches the bioquick – a fully metal-free leather with faster biodegradation. This way, Sinus gives a new response to the use of leather, perpetuating the memory of an ancient practice of recycling and recovery

Bioquick

Tanning process

By the metal-free tanning process, bioquick is tanned in an alkaline mixture and is completely free of nonylphenol, azo dyes, and formaldehyde.

Benefits

The result is a greener tanning process that is less harmful to health. Waste treatment also becomes more efficient and responsible, generating less pollution to accumulate in nature.

Bioquick
Faster degradation

bioquick’s decomposition is 5 times faster than the traditional leather which gives it the ability to rapidly reintegrate it to nature. This way, Sinus gives a new response to the use of leather, perpetuating the memory of an ancient practice of recycling and recovery.
