Leca Norge AS takes responsibility for our environment that provides us with the materials we use to create Filtralite products.

Reduction of emissions is a high-priority environmental factor
Controlling and limiting our energy consumption is an important issue, as production of lightweight expanded clay aggregates requires a great deal of energy. ISO 14001 is implemented in the entire Leca organisation in Norway, where Filtralite is produced. By working systematically with this norm, ambitious measurable environmental targets can be established and evaluated.

Transport & delivery
Leca Norge AS 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 needs and the type of media. Most types of material qualities can be delivered in bulk or in big bags, with road or sea transport.

By using tank trucks with blowing equipment, the Filtralite products can be pneumatically discharged directly into the plant filters. Filtralite Nature P, Filtralite Pure NC 0,8-1,6 mm and Filtralite Pure NC 1,5-2,5 mm are not recommended for pneumatical discharge.

Delivery in big bags can be done for all applications and all Filtralite products. 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 boats, or they can be stuffed into containers. Transport in containers is a good solution for smaller volumes and long sea transports.

Storage
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 absorb 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 Nature P should not be stored outdoors, as rainfall may wash out parts of the material, which may result in reduced efficiency of the media.
