The invention relates to the use of anti-bacterial glass which is in the form of a glass frit or open-pored foamed glass and to a disinfection device which is used to treat water by means of a glass filter.

A foamed glass plant growth support structure, including a foamed glass substrate and a plurality of interconnected pores distributed throughout the substrate.

The invention further relates to the use of powdery anti-microbial and/or anti-bacterial glass, which is in the form of a glass frit or as open-pored foamed glass.

It is also disclosed a particular kind of filling particulate material comprising a foamed glass material.

The foamed glass articles are annealed in a controlled cooling fashion to avoid thermal stress, cracking and embrittling.

The invention relates to a method for producing expanded glass granules.

According to the invention, the at least one soundproofing element (1) comprises a mixture of expanded glass or expanded clay and cement.

A process is useful for manufacturing wall boards from balls of expanded glass, expanded clay, pumice granules, mica or a similar material and a foamed organic binder such as epoxide resin, PU phenol resin or the like.

Finally, the invention relates to the use of such expanded glass granules as an additive in mortar or as a filler in rinsing liquid.

The ballistic layer is formed by an absorption layer (2, 2a, 2b) that consists entirely or mostly of expanded glass (21).
