The current situation in the energy sector suggests the possibility of using biomass in co-combustion systems as an alternative to other fuels. In the case of the North of Spain the amount of forest residues that is generated guarantees it as a valuable source of energy for the future. However, an effective exploitation of these residues must first overcome a number of serious problems such as ...

Japan imports more than 25 million cubic-meters of woodchips from various countries in the world to use these chips as raw materials for paper. The significant amount of the imports makes Japan the biggest woodchip importer in the world. Japan has many woodchip exporters, and Australia is one of its important exporters. However, logging operations for exporting woodchips in Australia have had n...

this study investigated maturation and stability levels during composting of quercus robur (qr) woodchips mixed with different nitrogen sources (horse manure, hm and lake mud, lm) for potential agronomic utilisation. the woodchips were mixed with hm and lm, respectively, at mixing ratios of 1qr:2hm or 1qr:2lm. the experiment was conducted in a greenhouse over 100 days. during composting, organi...

In this paper, a helical capacitive sensor is developed to measure the moisture content (MC) in woodchips. Firstly, based on orthogonal test method, structure of optimized obtain best possible uniform sensitivity. Then, effect type and random distribution woodchips MC measurement investigated. Finally, three different algorithms, including support vector machine, forest deep neural network, are...
