The use of anoxic chambers to eradicate insects has become popular
as most people are not happy to be using toxic chemicals. Therefore
it might interest Enrico Flaiani that there is a company in Italy
which rents out portable machines which extract the Oxygen leaving
Nitrogen and other gases. The company provides plastic sheeting,
heat sealers and valves. After bagging the material the Oxygen
remover is locked into a closed cycle and begins to pump out the air
filtering out the Oxygen. We have never tried the equipment as
logistics made transfers over to the UK difficult. However they
advertise as having been used by the Marciana National Library of
Venice, to treat 200,000 books. The machine is called VELOXY
