About us

The paper and pulp market has evolved significantly over the years, driven by technological advances and changing consumer preferences.

One major development has been the emergence of digital technologies, which have led to a decline in the demand for traditional paper products, such as newspapers and magazines. This has led to a shift in the focus of the paper and pulp industry towards the production of specialty and technical papers. There has also been a trend towards greater efficiency and sustainability in the paper and pulp industry, with many companies implementing measures to reduce water and energy usage, minimize waste, and reduce their carbon footprint.

Silox offers a wide range of hydrosulphite-based bleaching agents in different forms (liquid solutions, customized blends, stable powders) for the paper industry, and also provides a support service allowing customers to fine-tune their consumption in order to maximize performance, avoid losses, reduce costs and limit the environmental impact of their activity. Silox works tirelessly to reduce its own emissions, thus contributing to improving the impact of the entire value chain.

The textile industry has a long and rich history dating back to ancient civilizations. Early textiles were made by hand using simple tools and techniques, such as spinning and weaving. As civilizations developed, the textile industry underwent several major changes and innovations that greatly impacted the production and distribution of textiles.

In the 20th and 21st centuries, the textile industry has continued to evolve and adapt to changing market conditions and technological advancements. The widespread adoption of automation and computerization has led to the development of more efficient and precise production methods, and the use of synthetic fibers and new finishing techniques has resulted in the creation of a wide variety of innovative textiles.

Silox offers a large range of products for the textile industry such as:

• Sodium hydrosulphite used in vat/indigo dyeing, reduction clearing of dyed synthetic fabrics and yarns, cleaning dye-soiled dyeing machines, and stripping fabrics before re-dyeing;
• Sodium formaldehyde sulphoxylate (SafoliteTM) and zinc formaldehyde sulphoxylate (SafolinTM) used as a discharge printing agent on cotton and synthetic fabrics;
• Specialized denim grade sodium hydrosulphite (Hydros DTM) and proprietary reducing agents (LeucoSAFE D7TM, BleachtsilTM, Siloxin STTM)

Textile fiber recycling or regeneration refers to the process of recovering and reusing fibers from discarded textiles. The fibers can be recovered through a variety of methods, including mechanical, chemical, and thermal processes.

There are several benefits to recycling and regenerating textile fibers. It can help to reduce the amount of waste that is sent to landfills, conserve natural resources such as water and energy, and reduce the environmental impact of producing new textiles. Additionally, recycling and regenerating fibers can be a cost-effective way for manufacturers to obtain raw materials for their products.

Silox cooperates with several players in this field by supplying reducing agents, combining efficiency and low environmental impact.

Silox, through its subsidiary SNCZ, is a world leader in the anticorrosive pigment sector. Our product range is among the most extensive on the market (zinc phosphates, modified zinc phosphates, zinc-free phosphates, chromates, ion-exchanged silicas and polyphosphates), tailored to fulfill the most demanding needs.

With our pigments, our customers formulate the ideal anticorrosive coatings for markets as diverse as construction, automotive, industrial infrastructures, marine, aerospace and domestic appliances. We extend the life span of durable metallic goods, thus contributing to reducing the exploitation of nonrenewable natural resources.

Silox India produces zinc dust which is also used in anticorrosive paints. When applied to metal surfaces, it forms a layer of zinc oxide, which is highly resistant to corrosion. The zinc oxide layer is created through a chemical reaction between the zinc dust and the moisture in the air, a process known as galvanic corrosion. This layer acts as a barrier between the metal surface and the environment, protecting the metal from corrosion.

In addition to its corrosion-resistant properties, zinc dust is also a good reflector of infrared radiation, making it useful for heat-reflective coatings. It is a good conductor of electricity, making it useful in electrically conductive coatings.

Silox group, through its subsidiaries JGI and Hydrometal, is a major industrial recycler dealing with a wide range of complex non-ferrous metal-bearing residues, by-products, and secondary materials including components such as zinc, nickel, cobalt, molybdenum, germanium, tin, lead, antimony, copper, rare earths and precious metals from old or new applications like solar cells, batteries, low energy lights, wind turbines, etc.

As a key player in the circular economy and urban mining, we represent a valuable alternative to landfill and, as such, contribute significantly to the development of sustainable solutions to the depletion of natural resources. Our current technical set-up is unique in the recycling world and is based on hydro- and, when needed, pyro-metallurgy.

Our hydrometallurgical processes consume very little energy and produce very small quantities of CO2.

We are extremely active worldwide in the purchasing and selling of raw materials, by-products and products, which is building our commercial strength. We either direct the sourced materials to our Hydrometal plants to be refined or, alternatively, sell them directly to third parties all around the world.
