1 VIVERA Mineral Wl frm THERMOSELECT Prcesses The THERMOSELECT prcess accepts and efficiently prcesses cmmingle slid waste streams which can include municipal waste, cmmercial waste, refuse derived fuels (RDF), Autmtive Shredder Residues and industrial waste.

The prtin f the metals cmmnly is discvered at 1% - 5%. The inrganic prtins f the waste, including scrap metals and glass, becme mlten in the lwer sectin f the THERMOSELECT high temperature reactr which reaches temperatures in excess f C. The inrganic melt flws in a hmgenizatin reactr where mineral and metal cmpnents separate due t different densities. The specific weight f the mineral melt is abut 2,8 t/m 3. 2

In the hmgenizatin reactr the melt is purified thermally. The burners are perated under excess xygen cnditins t cmbust carbn particulate matter. The mlten inrganic melt allws the recvery f clean metal ally, free f cntaminatin and ready fr reuse after granulatin in a water basin. The metal prduct is dminated by its high irn cntent. The ally includes cpper, small amunts f nickel, chrme and zinc r similar. The main prtin f the inrganic material frms a glass-like mineral prduct that is nntxic, inert and usable in many ways. The chemical cmpsitin differs in dependence f the feedstck characteristics. An example is shwn in Fig. 2. Fig. 2: Typical Metal and Mineral Cmpsitin The chemical cmpsitin f the mineral prduct is cmparable t Basalt stne (vulcanite Magma), the main cmpnents t be SiO 2, FeO, CaO, Al 2 O 3, and Na 2 O. 3

The rcks mainly riginate frm stne quarries. Such interventin in the nature puts a strain n the climate balance f stne wl. Fig. 3: Adpted frm BBSR-Berichte KOMPAKT, Künstliche Mineralfaserdämmstffe 1/2011, Bundesinstitut für Bau-, Stadt- und Raumfrschung im Bundesamt für Bauwesen und Raumrdnung Melting f rcks requires a high amunt f energy between kwh/m 3. (Other insulatin, like rigid fam frm Plystyrl needs even mre: kwh/m 3.) The Basalt-like inrganics frm the THERMOSELECT prcesses already ccur in the liquid frm at the required temperature level f abut C. The hmgenized melt is immediately available fr fiber prductin withut the need f abve shwn energy fr melting f natural stnes. The ht melt be it frm natural stnes r riginating frm THERMOSELECT is directed via a buffer tank (ven) t a fiber spinning device. In the THERMOSELECT system, the heated buffer tank takes care f feedstck variatins in quantity and cmpsitin. 5

Similar t cttn candy n a fair, fibers are expelled by rtatin f the disc. Fiber spinning Fiber prductin by a hrizntal, fast rtating disc was patented in 1931 (N Reichspatentamt Germany). Mineral Wl prductin frm natural stnes as well as frm ht inrganic melt is prven technlgy. Mineral wl technlgy fr THERMOSELECT plants is prvided by ADVANTECH ( a cmpany with vast experience in stne and glass wl manufacturing. 6

This cntrls the density, and hence the rigidity and structural strength, f the end-prduct. The curing ven heat sets the resin binder.

Fr hardening it is frwarded by a chain belt thrugh a heated (abut 230 C) ven. As the wl mves thrugh the curing ven, it is cmpressed by varying the aperture f the ven. This cntrls the density, and hence the rigidity and structural strength, f the end-prduct. The curing ven heat sets the resin binder. Fiber fleece After the curing ven, facings such as aluminum fil r scrims can be applied t the surface f the stne wl accrding t prduct applicatins and/r custmer requirements. Blankets are cut int the desired dimensins. 7

It cmbines gd thermal insulatin effects with high nise prtectin, and is nncmbustible class A 1. Mineral Wl used fr thermal insulatin is subject t the Eurpean Nrm DIN EN 13162, Directive 89/106/CEE (thermal insulating material fr buildings factry made prducts frm Mineral Wl). The thermal cnductivity f Mineral Wl is lw. The insulatin effect results frm the inclusin f air in the interspaces between the fibers. 8

Under xidizing cnditins, Stne Wl prves high thermic stability. Under reductive cnditins it sinters at abut 800 C. Stne Wl is bi-sluble in human lung and thus n health risk. Occupatinal health and safety aspects are respected during the manufacturing prcess. Glass Wl can be cmpressed Stne Wl nt r little. Islating tiles frm Stne Wl are mre bearing, but less flexible. Stne Wl shws densities frm kg/m 3. The density has influence n wn weight f cnstructin (rf, wall) and temperature prtectin. Utilizatin purpses define prduct density. Mineral Wl is resistant against fungi, putridity, and bugs. Mdern plant grwing replaces natural sil by basalt fiber blankets r cubes in prfessinal green-huse applicatins fr industrialized planting f vegetables, fruits and flwers. The fibers imprve rt grwing, thus the plants can absrb mre nutrients. 9
