I have been producing and constructing straw panels in Russia for 15 years. I agree that the market for builders and architects is very conservative. And he doesn’t want to accept everything new. But straw panels are a great material!
Pumicecrete is by far the best and very affordable building material. Pumicecrete is a mixture of pumice cement and water mixed and poured into a set of reusable forms walls are poured from 12"to 24" thick pumicecrete is fireproof termite proof rust rot and mold proof non toxic and has a high R value and good sound attenuation solid poured walls means no critters can live in your walls Pumicecrete can be built for a fraction of the cost and time and pumice is one of the few building materials that can go directly from the mine to the job site ready to use without any additional possessing and zero waste Take care Ray
Not really. Primary energy for making pumice is quite high (and I am not talking about extraction the clay and adding cement). With density of 1000kg/m3 the is lambda 0,4 and strawbale has cca 0,05 so technically pumicecrete is 8x worse insulation then strawbales.
accually not really. Straw is cellulose = source of carbon, not nitrogen. If we calculate carbon cycle during lifespan is zero (methane produced during decomposition). If we put straw out of the cycle and hold it for 80-100 years, we can absorb a lot of carbon from athmosphere. And straw is waste product in agriculture, it grows every year in large quantities.
@@MarianOntkoc Where do you think the straw comes from? The Krebs Cycle of the oat straw or wheat straw depends on N2 to elongate the cellular structures in order to create the cellulose yield in tons/ acre so that harvesting it is economically viable.
@@MarianOntkoc Also, straw is not a waste product in agriculture. Farmers bale it and use it for livestock feed and bedding. I stacked enough of it in the barn to know. The only straw left on the field is the 2 inches of stubble, and no, it doesn't turn into methane, it builds organic matter in the soil and over time the aerobic and anaerobic bacteria breaks it down so the carbon, P, K, and N left in it becomes plant available and is used by following crops in the rotation.
@@indivisibleman8596 I am talking about dry straw at the harvest. There is no Nitrogen. Carbon is necessary during compost process, but composting emits greenhouse gases. Wheat straw isn't that nutritious to feed the stock and it is agricultural byproduct. Is it good source of homogenous cellulse.

Straw belongs in the soil to build organic matter. If they used fertilizer to grow the crop, it's not 'renewable.'
