Grifola frondosa is an economically important edible and medicinal mushroom usually produced on substrate consisting of sawdust supplemented with wheat bran. Cultivation of G. frondosa on crop straw (corn cob, corn straw, rice straw, and soybean straw) as a substrate was optimized by using the D-optimum method of the simplex-lattice design, and the alternative of crop straw as a substitute for ...

Cow dung slurry containing a total of 7.4 10 5 E. coli was applied to laboratory-scale microcosms of Pinus radiata sawdust or bark. Rainfall was simulated by application of water at rates of 25 mm h -1 or 50 mm h -1 over 30 minutes. For sawdust 5% and 11% (respectively) of the E. coli were transferred to drainage compared to 12% and 28% for bark. After collection of drainage less than 10% of th...

H ighbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and pH of 4.5-5.5. Coniferous sawdust is the blueberry industry standard soil amendment and mulch in the Pacific Northwest, USA. However, sawdust prices are increasing, and its availability is becoming limited. Therefore, many blueberry producers are interested in compost as an alternative to sawdust, whi...

Abstract: Heavy metal contamination of drinking water poses serious threat to public health and ecosystems. Chronic exposure to such metal contamination can lead to various health problems including nerve and organ damages. Thus, removal of heavy toxic metals from the contaminated water supply is a critical issue of water quality management. Naturally-occurring resources have been attractive ca...

Untreated and hot-water-extracted (HWE) Norway spruce (Picea abies) sawdust was cooked using the sulfur-free oxygen-alkali (OA) method under the following conditions: temperature, 170 °C; liquor-to-wood ratio, 5:1 L/kg; and NaOH charge, 19% on the oven-dry sawdust. In comparison with earlier studies conducted with birch sawdust, the spruce cooking yield data, together with the amount of the pul...

Activated carbon from sawdust was produced with an environmentally friendly process involving single-stage carbonization and activation steam at 800°C. Production is scalable because lignocellulosic biomass ubiquitous worldwide as a waste or virgin material. Single-stage production without any cooling steps between easier in larger scale production. Monometal adsorption multimetal of cobalt, ni...
