A farm scale composting drum was used to study exhaust gases from horse manure, and from horse manure mixed with tomato plant residues (TPR) with a lower C/N ratio. To study whether this addition increased gaseous losses of nitrogen (N) and sulphur (

Torrefaction has been recognized as a promising strategy to improve handling and storage properties of wood-based pellets, thus producing a uniform-quality commodity with high energy density and hydrophobicity. In this work, pellets produced from spr

Modern wood stoves can achieve high efficiency and relatively low levels of harmful emissions. However, controlling wood logs’ combustion remains challenging, and the emission levels of unburnt compounds are generally higher than for e.g. wood pell
