For Saint-Gobain all emissions are a high-priority environmental factor.

Emissions are a high-priority environmental factor

Future energy consumption is another important issue, as production of light weight expanded clay aggregates require a great deal of energy. ISO 14001 is implemented in the entire organisation of Saint-Gobain in Norway, where Filtralite is produced. By working systematically with ISO 14001, measurable environmental targets can be established and evaluated.


Saint-Gobain in Norway is certified both on quality, environment and for production of material for use in drinking water treatment: 

Requirements: NSF International/ANSI 61
Quality: ISO 9001
Environment: ISO 14001
Products for use in treatment of drinking water: EN 12905

Transport & Delivery

Saint-Gobain has a lot of experience with transporting and delivering Filtralite to almost all parts of the world. Delivery method varies from project to project, subject to the customers need and the type of media. Most types of material qualities can be delivered in bulk or in big bags, with road- or sea transport. 

Reduction of transport-emissions are high-priority

All types of Filtralite can be delivered in bulk. Bulk deliveries can be made to all parts of the world, either as road transport with trucks, or as sea- or river transport with vessels. By using tank trucks with blowing equipment, the Filtralite materials can be pneumatically discharged directly into the filters. Filtralite P, Filtralite NC 0,8-1,6 mm and Filtralite NC 1,5-2,5 mm are not recommended for pneumatical discharge.

Delivery in big bags

Delivery in big bags can be done for all applications and all Filtralite qualities. Big bags that are open at the top will normally be used. Most of the materials are normally delivered in 1,5 m3 big-bags. For deliveries to on-site wastewater treatment systems, the material is delivered in 1,0 m3 big bags. The big bags can be transported on trucks, trains or vessels, or they can be stuffed into containers. Transport in containers is a good solution for smaller volumes and long sea transports.


During delivery of Filtralite, it can sometimes be necessary to temporarily store the material. Filtralite filter medias can be stored outdoors without decrease of quality. It should be taken into consideration that the materials will adsorb water during rainfalls, which will make the media heavier and may increase transport costs. To avoid degradation of the big bags they should not be stored outdoors for more than 6 months. Filtralite P should not be stored outdoors, as rainfall may wash out parts of the material, which may result in reduced efficiency of the media.
