17. LIGNIN HYDROTHERMAL LIQUEFACTION IN SUBCRITICAL WATER TO PRODUCE BIOFUEL AND CHEMICALS
Abstract : Lignin is one of the most abundant amorphous macromolecules found in nature. Along with cellulose and hemicellulose, it forms a main component of biomass, and is mainly responsible for providing strength, rigidity and resistance to degradation. From a chemistry perspective, lignin is an important source of aromatics. READ MORE

18. In silico tools in risk assessment : of industrial chemicals in general and non-dioxin-like PCBs in particular
Abstract : Industrial chemicals in European Union produced or imported in volumes above 1 tonne annually, necessitate a registration within REACH. A common problem, concerning these chemicals, is deficient information and lack of data for assessing the hazards posed to human health and the environment. READ MORE

19. Lignin Conversion to Value-Added Small-Molecule Chemicals : Towards Integrated Forest Biorefineries
Abstract : Lignin is the most abundant aromatic biopolymer on Earth and has significant potential as a feedstock for industrial use. Due to its intrinsic heterogeneity and recalcitrance, lignin has been regarded as a low-value side-product in the pulp and paper industry and in second-generation biorefineries. READ MORE

20. Inconsistencies and missing links in EU chemicals legislation
Abstract : The EU chemicals legislation consists of the Regulation on Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) and the Regulation on Classification, Labelling, and Packaging of Substances and Mixtures (CLP), complemented by over fifty regulations and directives regulating specific uses and products. While regulating individual uses may offer a faster and simpler approach to protecting human health and the environment from hazardous chemicals, it can also lead to inconsistencies, such as gaps and overlaps.
