||This document describes the characteristics of Willow SRC in terms of moisture content, net and gross calorific value, dry ash content and its variability, dry nitrogen content, dry chlorine, barium, beryllium, chromium, cobalt, copper, molybdenum, nickel, vanadium, zinc, arsenic, antimony, mercury, cadmium, lead, fluorine, bromine, aluminium, calcium, iron, potassium, manganese, sodium, phosphorus, silicon and titanium content.
This document is one of the 13 appendices to the Final Report from the first Phase (2015/16) of the Characterisation of Feedstocks (CofF) project, the primary purpose of which is to provide an understanding of UK produced biomass properties, how these vary and what causes this variability.
The purpose of this report plus its related parts is to report the variability in feedstock properties of UK produced energy biomass, the causes of these variations and the relationship between the feedstock properties and the provenance data collected. Five feedstocks were studied: Miscanthus, willow short rotation coppice (SRC), poplar SRC, poplar grown as short rotation forests (SRF), and spruce SRF, with poplar and Sitka spruce selected to represent broadleaved and coniferous biomass crops respectively. Provenance data include site properties (such as general climate zone and soil chemistry), the conditions at the time of sample collection, and past management of the site and crop with soil samples also collected for analysis. The feedstock samples were analysed in UKAS accredited laboratories.
