To assess the sustainability along the whole value chain, life cycle-based methodologies have been developed over the last years. Life Cycle Assessment (LCA) considers environmental impacts along supply chains, from extraction of raw materials to end-of-life of products (ASI 2006). The aim of this paper is to describe the use of LCA to assess the environmental impacts of the use of waste wood for energy production. Important methodological aspects on the use of LCA for the assessment of waste wood are presented using two different case studies from the H2020 projects STORY (Added value of STOrage in distribution sYstems) and TORERO (TORefying wood with Ethanol as a Renewable Output: large-scale demonstration).

In order to treat household waste Romerike Avfallsforedling (ROAF) located in Skedsmorkorset north of Oslo, Norway required the installation of a mechanical Treatment facility to process 40,000 tpa. Together with a Norwegian based technical consultancy Mepex and German based technical consultancy EUG the project was tendered and the plant build against a technical specification. In 2013 the project was awarded to Stadler Anlagenbau and since April 2014 the plant is in operation with an hourly throughput of thirty tons. The input waste contains specific green coloured bags containing food waste which is collected together with the residual waste from the households. The process recovers successfully the green food bags before the remaining waste is mechanically pre-treated and screened to isolate a polymer rich fraction which is then fully segregated via NIR technology in to target polymers prior to fully automated product baling. Recoverable Fibre is optically targeted as well as ferrous and non-ferrous metals. All food waste is transported off site for further biological treatment and the remaining residual waste leaves site for thermal recovery. In 2015 the plant has been successfully upgraded to forty tons per hour and remains fully automated including material baling.
Study on biodegradability of wood residues

Bark and timber residues (waste wood) mingled with soil, dirt and stones have so far been landfilled without any alternative use. The aim of this study was to propose a technology for biological treatment of this waste, enabling to produce quality compost.
Communally Funded Waste Treatment Plants

Communally funded waste disposal in Germany was a major achievement of the 19th century. Until then, all waste was simply thrown out. Proper disposal helped combat epidemics and diseases that posed a major problem in those days. The creation of hygienically bearable conditions was an intrinsic task of the waste disposal service. For more than 100 years now, waste incineration has also been communally funded. More than 100 years ago, the first plant began operation in Hamburg.
The adsorption of Cd(II) ions by poplar wood sawdust

The biosorption of cadmium (II) by raw and poplar wood sawdust modified with 1% NaOH at room temperature was studied in a batch system. The modified poplar wood sawdust had higher adsorption capacity for about five times, and adsorption affinity for about twenty times related to unmodified one.
