A firewood processor in Russia Firewood Processor in USA. A firewood processor is a machine designed to cut and split firewood with minimal manual handling of the logs. There are typically four main parts of the machine, each dedicated to a separate function. Processing begins with a log pile – a pile of logs that have been de-limbed and cut ...
It may include skidding, on-site processing, and loading of trees or logs onto trucks [1] or skeleton cars. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard.
Thermally modified wood is engineered wood that has been modified by a controlled pyrolysis process of wood being heated to (> 180 °C) in an oxygen free atmosphere. This process changes to the chemical structures of wood's cell wall components lignin , cellulose and hemicellulose which decreases its hygroscopy and thus increases dimensional ...
In the narrow sense of the terms, wood, forest, forestry and timber/lumber industry appear to point to different sectors, in the industrialized, internationalized world, there is a tendency toward huge integrated businesses that cover the complete spectrum from silviculture and forestry in private primary or secondary forests or plantations via the logging process up to wood processing and ...
Paper engineering is a subfield of wood processing. The major wood product categories are: sawn timber, wood-based panels, wood chips, paper and paper products and miscellaneous others including poles and railway sleepers. Forest product processing technologies have undergone extraordinary advances in some of the above categories.
Pyrolysis liquids from slow pyrolysis of bark and hemp have been tested for their antifungal activity against wood decaying fungi, showing potential to substitute the current wood preservatives [99] while further tests are still required. However, their ecotoxicity is very variable and while some are less toxic than current wood preservatives ...

Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide. A plasma torch powered by an electric arc is used to ionize gas and catalyze organic matter into syngas, with slag [1] [2] [3] remaining as a byproduct.
