Abstract
The paper aims to analyze the biomass at one year growth, resulting from the cultivation of the INGER energy willow clone as a short rotation crop (SRC), in order to use it as a renewable fuel. The paper completes the data in the field of renewable energies in the context of decreasing fossil energy reserves worldwide and emphasizing the impact on renewable energies. The effect of a contaminated land on the survival rate of the planted seedlings and the effect of the energy willow culture on the composition of the contaminated soil are analyzed. The obtained results show that the biomass characteristics, such as the calorific power of about 18,21 kJ/g to18,90 kJ/g, and the ash content of about 2,25 %, are comparable with the ones of other lignocellulosic energy materials. The results found in this studyshowed that the woody biomass in the first vegetation year of energy willow can be used directly as a renewable fuel without the need for compaction in the form of briquettes or pellets
Highlights
The European energy strategy has several current and prospective goals in terms of reducing fossil fuels and increasing the use of renewable resources, such as biomass
Apart the production of energy biomass (Adler et al 2005, Labrecque and Teodorescu 2005, Arevalo et al 2007), such crops represent the solution for some environmental phenomena, being used for recycling the residual water (Börjesson and Berndes 2006, Holm and Heinsoo 2013) with a positive effect on willow growth (Dimitrious et al 2011, Hammar et al 2014), for the absorption of heavy metals (Mleczek et al 2010), and for food from mixed crops (Ghaley and Porter 2014)
The main objective of this paper was to analyze the biomass at one year growth, resulting from the cultivation of the INGER clone energy willow as a short rotation crop (SRC) obtained from contaminated and non-contaminated land, in order to use it as a renewable fuel
Summary
The European energy strategy has several current and prospective goals in terms of reducing fossil fuels and increasing the use of renewable resources, such as biomass. Wood biomass used for energy production is obtained from the exploitation of forests, residues and, wastes from the wood processing industry, and from other crops producing lignocellulosic biomass (Ericsson and Nilsson 2006). Among such crops for energy biomass, short rotation willow crops (SRCs) can become a good source of income for producers (Manzone and Balsari 2014, Buchholz and Volk 2011). These crops can store carbon for short term (Rytter 2012, Ens et al 2013, Fiala and Bacenetti 2012).
