16. Effects of pyrolysis and incineration on the chemical composition of Li-ion batteries and analysis of the by-products
Abstract : In the present work, the effects of pyrolysis and incineration on the composition of Li-ion battery cell materials and their dependence on treatment time and temperature were investigated. Waste from Li-ion batteries was treated at 400˚, 500˚, 600˚, and 700˚C for 30, 60, and 90 minutes. READ MORE

17. Comparison of incineration and pyrolysis of NMC-lithium-ion batteries – determination of the effects on the chemical composition, and potential formation of hazardous by-products
Abstract : Several industrial lithium battery recycling processes use thermal pre-treatment in an oxidative or inert atmosphere, or in a vacuum, to separate the battery components and remove organic material. However, a comparison of these pre-treatments on the microstructure and composition of waste material and production scrap LiBs has not been explored as well as there is a scarcity of information about the character of by-products generated during the processing.

19. Entrained-Flow Gasification of Black Liquor and Pyrolysis Oil : Experimental and Equilibrium Modelling Studies of Catalytic Co-gasification
Abstract : The last couple of decades have seen entrained-flow gasification of black liquor (BL) undergo an incremental process of technical development as an alternative to combustion in a recovery boiler. The ability of the technology to combine chemical recovery with the production of clean syngas renders it a promising candidate for the transformation of chemical pulp mills into integrated forest biorefineries.

20. Recovery and reuse of TiO2 and other pigments from paint waste
Abstract : Titanium dioxide (TiO2) has numerous applications in our society, most notably as a white pigment in products such as paint, paper and plastic. Since 2010 there has been a sharp increase in the demand for and price of TiO2. As a result new and innovative ways of TiO2 production are needed. READ MORE
