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...

Greenhouse plant growers can substitute rice hulls for perlite in their media without the need for an increase in growth regulators, according to a Purdue University study.Growing media for ornamental plants often consists of a soilless mix of peat and perlite, a processed mineral used to increase drainage. Growers also regularly use plant-growth regulators to ensure consistent and desired plant characteristics such as height to meet market demands. Organic substitutes for perlite like tree...

TROY, N.Y. -- Eben Bayer grew up on a farm in Vermont learning the intricacies of mushroom harvesting with his father. 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...
Vermiculite is a natural mineral which expands with the application of heat. It is formed by hydration of certain basaltic minerals, and is often found in association with asbestos. 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...
