Introduction. Tsukinuno bentonite mine (NW Japan) is a source of Miocene age Na (at depth) and Ca (near surface) bentonite. The site holds great potential for studying processes of direct relevance to safety cases (SC) for radioactive waste repositories which will utilise bentonite as part of their multibarrier safety system.

Innovations in the Use of Bentonite in Oenology ...

 · The disposal of bentonite represents a limitation exacerbated by the fact that bentonite is not reusable, due to the lack of processes that promote the desorption of the adsorbed proteins. Alternative treatments and adjuvants have been sought in oenology because of the drawbacks of bentonite, such as its direct and indirect costs.

Bentonite

Bentonite is an offwhite montmorillonite clay formed from altered volcanic ash. It has a sheetsilie structure and is especially notable for the way in which it absorbs and loses water and for its baseexchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.
