vermikulit kao i prelit su zagrijavani minerali/stijene i u njima nema azbesta.
inače se nebi reklamiralo kao ekološki čist i zdravstveno ispravan proizvod niti bi ih se upotrebljavalo u tolikoj mjeri. naravno, postoji građevinski vermikulit i perlit,ali se to ne koristi u našem slučaju.

Mogao bi biti dobar građevinski...azbesta nema...to je zabranjeno a opet azbest je problem ako se udiše. Jedino što bi trebalo je vidjeti aditive i ostale dodatke u građ. vermu i perli..dali su topljivi u vodi odnosno na neki način toxični.

Jedini problem bi bio ako taj građevinski u sebi ima teških metala, jer ih gljive absorbiraju i koncentriraju. Olovo, živa i td.
Vermikulit je ionako potpuno nepotreban kod kultivacije gljiva, može poslužiti kao aditiv, ali daleko od toga da je neophodan.

evo iz wikipedie o vermikulitu

Asbestos contamination

Although not all vermiculite contains asbestos, some products were made with vermiculite that contained asbestos until the early 1990s. Vermiculite mines throughout the world are now regularly tested for it and are supposed to sell products that contain no asbestos. The former vermiculite mine in Libby, Montana, did have tremolite asbestos as well as winchite and richterite (both fibrous amphiboles) — in fact, it was formed underground through essentially the same geologic processes as the contaminants. A vermiculite mine in Virginia has also been found to be contaminated by asbestos.[6]

Pure vermiculite does not contain asbestos and is non-toxic, but it can become contaminated over long periods if there is a presence of a secondary mineral called diopside. After millions of years of weathering, the biotite turns into vermiculite and the diopside turns into asbestos.

Controversy over health risks

The largest and oldest vermiculite mine in the United States was started in the 1920s, at Libby, Montana, and the vermiculite was sold under the commercial name Zonolite. The Zonolite brand and the mine was acquired by the W.R. Grace Company in 1963. Mining operations at the Libby site stopped in 1990 in response to asbestos contamination. While in operation, the Libby mine may have produced 80% of the world's supply of vermiculite.[7]

The United States government estimates that vermiculite was used in more than 35 million homes, but does not recommend its removal. Nevertheless, homes or structures containing vermiculite or vermiculite insulation dating from before the mid 1990s—and especially those known to contain the "Zonolite" brand—may contain asbestos, and therefore may be a health concern.

An article published in the Salt Lake Tribune on December 3, 2006, reported that vermiculite and Zonolite had been found to contain asbestos, which had led to cancers such as those found in asbestos-related cases. The article stated that there had been a "cover-up" by W.R. Grace Company and others regarding the health risks associated with vermiculite and that several sites in the Salt Lake Valley had been remediated by the EPA when they were shown to be contaminated with asbestos. W.R. Grace Company has vigorously denied these charges.

The vermiculite deposit at the mine in Libby, Montana, was (and is) heavily contaminated with asbestos.[8] Numerous people were knowingly[9] exposed to the harmful dust of vermiculite that contained asbestos. Unfortunately, the mine had been operating since the 1920s, and environmental and industrial controls were virtually non-existent until the mine was purchased by the W.R. Grace Company in 1963. Yet, knowing the human health risks, the mining company still continued to operate there until 1990. Consequently, many of the former miners and residents of Libby have been affected and continue to suffer health problems. Over 200 people in the town have died from asbestos-related disease due to contamination from vermiculite mining from nearby Zonolite Mountain, where soil samples were found to be loaded with fibrous tremolite (known to be a very toxic form of asbestos), and countless others there who insulated their homes with Zonolite have succumbed to asbestos-related diseases, most of whom never were employed in environments where asbestos was an issue.[10]

After a 1999 Seattle Post-Intelligencer story claimed that asbestos-related disease was common in the town, the EPA, in response to political pressure, made cleanup of the site a priority and called Libby the worst case of community-wide exposure to a toxic substance in U.S. history.[11][12] The EPA has spent $120 million in Superfund money on cleanup.[12] In October 2006, W. R. Grace Company tried to appeal the fines levied on them from the EPA, but the Supreme Court rejected the appeal.[13] The United States government is also pursuing criminal charges against several former executives and managers of the mine for allegedly disregarding and covering up health risks to employees.[13] They are also accused of obstructing the government's cleanup efforts and wire fraud. To date, according to the indictment, approximately 1,200 residents of the Libby area have been identified as suffering from some kind of asbestos-related abnormality.[14] Jury selection was to have been completed in February, 2009.[15][16] The case ended in acquittals on May 8, 2009.[17] On June 17, 2009, the EPA issued a public health emergency in and near Libby, thereby allowing Federal agencies to provide funding for health care, and for removal of contaminated insulation from affected homes.[18]

Razumijem što želiš reći....da azbesta ima u vermitu..čak i rudnicima. Te da je azbest na neki način napravljen by vermikulit.

Ali vic je u ovome:

NITI JEDAN DANAŠNJI PRODUKT KOJI SADRŽI VERMIT KOJI ČE BITI UKLJUČEN U GRADNJU(ali i inače zbog potpune zabrane azbesta i azbestnih sličnosti)NEČE IMATI AZBESTA U SEBI. SAV DANAŠNJI VERMIKULIT MORA BITI BEZ AZBESTA!!! INAČE SE NE MOŽE KORISTITI KAO SIROVINA ZA PROIZVODNJU GRAĐEVINSKOG MATERIJALA.

kužim ja, al kužiš ti da kad kupiš onu bijelu vrečetinu u zelenom hitu nema nikakve deklaracije etc. može unutra bit i zlato i štakorje govno ali dečko ti prodao vermikulit pa ga ti zoveš vermikulitom
a od kud ga je nabavio samo on zna

Očajan sam. Prošao sam danas čitav grad u potrazi za materijalima i sve sam pronašao osim prokletog vermikulita. U cvjećarnicama ga nema, također ni u trgovinama građevnog materijala. Postoji li neka jednako (ili bar približno jednako) dobra zamjena?

Pročitao sam u jednom vodiču da se koristi samo smeđa riža, koliko je to preporučljivo?

Vermikulit ti je nepotreban, nemoj da se maltretiras da ga trazis, jednostavno stavi zemlju umesto njega, jedina je razlika sto ces morati cesce da vlazis zemlju i to je to. (mozda i jos neka sitnica, nisam bas strucan u razlikama izmedju ta 2)
Procitaj o sterilizaciji zemlje u gajdu '' PC na kukuruzu'' imas u metodama uzgoja.
E sad jedino ako hoces PF-tek, onda ti treba.

Da li si kada vidio ili čuo da Psilocybe cubensis u prirodi raste iz vermikulita? Nisi? Ma kako to, kada ga se očito može uzgajat samo s vermikulitom? Kejsing je totalna glupost, silovanje gljiva da izbace koji plod. P. cubensis se najbolje uzgaja na konjskom izmetu ili na kokosovom tresetu.
