Holz als Roh- und Werkstoff, 1999
Wood is an anisotropic material and, further, because of its natural origin the mechanical properties might significantly differ also between each of the samples tested. Ordinary methods for evaluation of solid mechanic properties often destroy the tested specimens. It is therefore not common practice to evaluate more than one property, e.g.

EXPERIMENTAL JUSTIFICATION USE OF WOOD ASH
HUMAN. ENVIRONMENT. TECHNOLOGIES. Proceedings of the Students International Scientific and Practical Conference, 2017Biomass as a source of energy will reduce dependence on imported fossil fuels, but at the same time, we add value to countries where biomass fuel sources are just beginning to thrive, in addition to providing renewable energy sources. Biomass energy is recognized as an important component in many countries, as future energy scenario and could ...

Wood ash for application in municipal biowaste composting
Bioresource Technology, 2011This study aimed to clarify the impacts of pH control by wood ash amendment on biowaste composting processes. To achieve this, fresh source separated municipal biowaste was mixed with low doses (2-8% wt/vol) of wood ash and processed in a pilot and large-scale composting systems. The results indicated a correlation between a low initial pH and delay in

AbstractMostly disposed without treatment, fly and biomass ashes have been a challenge that threatens the environment. To use them as geoenvironmental materials for thermal insulating purposes, a fundamental studying of thermal property of the pure ashes is crucial.

Burns due to wet wood ash: three cases
Cutaneous and Ocular Toxicology, 2013Wood ash, a traditional multipurpose agent, is sometimes used under occlusion as a folkloric prescription to ease pain and edema. Adding water or oil to ash forms a mixture with strong alkaline properties. We present three interesting cases who sustained full-thickness burns after application of a poultice of wetted wood ash for the treatment of leg ...

Indetermined chair frames of ash wood
Holz als Roh- und Werkstoff, 1997During recent years more interest has been emphasised on wood as a construction material. This is so because wood is a renewable resource and also because problems with waste do not emerge when the wooden structure is taken out of operation. On the contrary this waste is still a resource even if the structure is demolished. Wood could always be used as

Effect of wood ash treatment on improving the fermentability of wood hydrolysate
Biotechnology and Bioengineering, 2003AbstractSoftwood hydrolysates were overlimed with wood ash to improve the fermentability of hydrolysates. It could be demonstrated in fermentation tests that wood ash treatment increases fermentability compared to the hydrolysates untreated and treated with alkaline compounds such as Ca(OH)2, NaOH, and KOH, which are commonly used for overliming.

Ash Fusion Characteristics of the Blends of Reed and Wood Ashes
2012The reed, waste wood, wood chips etc. are available for energy purposes in Estonia, while mainly utilized in fluidized bed boilers for heat production in district heating systems of smaller settlements. There is no correlation in the ash fusion characteristics of biomass blends.

Wood ashes come from different industries. They are the residue, left after combustion of wood in biomass boilers. Compositions depend on the type of the input, nature of the wood, the temperature of burning, the treatment cycle and the duration. They are rich in Ca, K, Mg and Si elements (pH=9-13.5) and despite their composition with the nutrient ...
