SOLVAY is manufacturing and placing on the market dihydrate calcium chloride (CASO® FEED), feed material of mineral origin in conformity with the European Directive 2002/32/EU and its amendments on undesirable substances in animal feed  and certifying all the produced batches with Certificates of Conformity . 
With the aim to guarantee both the traceability and the safety of the entire food chain, SOLVAY, in the context of the European Regulations  178/2002/EC and 183/2005/EC, has implemented and maintains an HACCP system for  its manufacturing plant .
Putting in practice the rules of Regulation 183/2005/EC, SOLVAY has registered its production plant in  Rosignano (Italy) as producer of industrial calcium chloride of mineral origin for animal feed, as indicated in the Italian Ministerial Decree of 13 of November 1985, to the local Authority USL 6 of Livorno (Italy) in compliance with Decree 6610/2005 issued by the Tuscany Region, adopting the rules of Articles 5 and 9 of the Regulation 183/2005/EC itself.
With the scope to assure the safety of the product during its transportation, SOLVAY has defined some internal procedures that define the acceptance criteria of the trucks that will be used for the deliveries  respecting the GMP Plus quality rules, managed by  GMP Plus International as reference, as well as have obliged all his transporters for registering themselves as feed operators to the competent authorities.

CASO®  is a calcium provider in feed for ruminants, swines and lambs.

Calcium chloride is not classified as a hazardous material and is, therefore, not subject to specific handling regulations. The various modes of transportation include: bulk rail cars (30-90 t), bulk trucks (up to 20 t), box rail cars, and van flatbed trailers. Depending on whether the shipments are in liquid or dry form, there are several variations to the above general classifications. Dry bulk calcium chloride can be stored in bins fabricated from most construction-grade steel materials. Care should be taken to minimize moisture. Venting should be limited to times of filling and discharging calcium chloride from the storage bin. Liquid calcium chloride can be stored in either hoizontal or vertical cylindrical steel tanks. Fiberglass and plastic may also be used within limits of strenght and temperature. Because calcium chloride is hygroscopic, the common safety precautions involved in the handling of chemicals should be observed: wearing gloves, boots, long-sleeve shirts, and safety glasses, and if dry products are being handled, dust protection must be insured.

In the context of  Eurpean Regulation N° 178/2002 laying down procedures in matters of food safety and Regulation N°852/2004 laying down general food hygiene requirements to be respected by food businesses, the general requirements of the food law are that food must not be placed on the market if it is unsafe (i.e. if it is harmful to the health and/or unfit for the consumption).
A Hazard Analysis Critical Control Point (hereinafter referred to as HACCP) system is implemented in our manufacturing plant and it consists of applying the following principles:

- the conduction of a hazard analysis and the identification of preventive measures;
- the determination of the Critical Control Points (CCPs),
- the establishment of critical limits, monitoring procedures, corrective actions (via internal audits), record-keeping and documentation procedures (ensuring traceability and claims treatment) and the establishment of verification procedures.

Furthermore our manufacturing plant located in Rosignano (Italy) is registered by the competent authority and a sanitary/hygiene authorization was issued for the manufacture, the storage and the marketing of calcium chloride as food additive characterized by the European Number E509 (Autorizzazion igienico sanitaria N. 111).

Safety & Environment: to be taken seriously. Safety and the environment are as important for you as they are for us. We make it a point of honour to keep you well informed.

Since calcium chloride is classed as an 'irritant', it is necessary to observe certain elementary precautions. These include :

- never place the skin in prolonged contact with CASO® or any of its solutions
- use water, preferably lukewarm, to thoroughly rinse any part of the body affected by this product.
- wear gloves made from rubber or plastic.
- avoid any inhalation of CASO® dust.
- wear protective glasses when handling CASO®.
- avoid working with equipment made from leather.

With regard to the effects of CASO® on the environment, we offer you the following thoughts :

- Calcium and chlorine ions are everywhere in the atmosphere and are used physiologically for living organisms. They occur naturally in the soil, rocks and sediment, as well as in surface or deep water.
- Calcium is an essential element in the cycle of life. It plays a part in the mineral balance of plants and is an important element in the composition of the water in our rivers and in our mains supplies. The effects on the environment of calcium in the form of calcium chloride are not to be feared.
- Chlorine ions, the other component of CASO®, should be looked at from two points of view.

On the whole, the chlorine found in river water rarely exceeds the levels allowed by official bodies responsible for public health and the environment. Certain periods of the winter have revealed very short peaks in concentration. Recent studies have shown that these occurrences do not have an important influence on the aquatic environment.

As far as fluoride is concerned, even in those areas where CASO® is used intensively do we find anything like the destruction of plants put forward by certain alarmists. The occasional accelerated fall of leaves or plant thorns (biological regulators of the latter) have been observed, as has the appearance of plants which are particularly resistant to chlorine or the mutation of certain species of plant.

In 45 years of spreading CASO® on our roads, no serious incident concerning an animal ingesting this product has been brought to our attention.
