11. Chemical and Biochemical Biorefineries in Kraft Pulp Mills – Process Integration and Economics for Three Concepts
Abstract : Some of the advantages of integrating biorefinery concepts with kraft pulp mills are that the utility system can be shared and that mass and energy streams can be exported from the pulp mill to the biorefinery or vice versa. These measures may result in lower investments and operating costs for the biorefinery compared with stand-alone operations. READ MORE

15. CHALMEX FS-13 investigations for process implementation
Abstract : From successive neutron absorption by uranium in nuclear reactors, transuranic elements such as neptunium, plutonium, americium and curium are produced. These elements are the main reason for the long-lived, highly radiotoxic and heat-producing nature of spent nuclear fuel. READ MORE
