Substrate made from waste glass performs well in greenhouse applications In the greenhouse business, organic and inorganic growing substrates are chosen for the physical and chemical properties necessary to support specific crops and growing conditions. One important physical property in substrates is air-filled pore space, a particularly important characteristic that allows for gas exchange between plants' roots and the outside atmosphere. Perlite and parboiled rice hulls are the two of...

Now the Rensselaer Polytechnic Institute graduate is using that experience to create an organic insulation made from mushrooms. More at home on a pizza, mushrooms certainly aren't a typical building material, but Bayer thought they just might work when given the assignment two years to create a sustainable insulation. Combining his agricultural knowledge with colleague Gavin...

Perlite is an amorphous glass mineral of volcanic origin. Typical analysis: 70-75% SiO2, 12-15% Al2O3, Na2O 3-4%, K2O 3-5%, Fe2O3 0,5-2%, MgO 0,2-0,7%, CaO 0,5-1,5% Loss On Ignition 3-5% Properties: When it reaches temperatures of 850"“900 °C, perlite softens (since it is a glass) and water trapped in the structure escapes and this causes the expansion of the material to 7"“15 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the...

Mining operations in Libby, Montana were closed in 1990 in response to asbestos contamination. Expanded vermiculite is used as a soil conditioner, as loose-fill insulating and packing material, as an insulating filler for plaster and concrete compounds, and as a carrier for dry handling and slow release of...
