This work reports on the possibility to use a new class of materials as Ni-supports for catalytic production of hydrogen. This new materials are named geopolymers and they are amorphous or semi-crystalline aluminosilicate synthesized as monoliths. The manufacture of geopolymers has many benefits being low-cost, environmental friendly, energy-saving, and resource-recycling. Furthermore, they possess mesoporosity, good resistance to high temperatures and chemicals, high strength and ion exchange properties. Ni-based catalyst using geopolymer as support shows complete catalytic conversion of ethanol in three different reactions (reforming, autothermal reforming, and partial oxidation) and high hydrogen content in the final products (70%). © 2014 WIT Press.

Recently, researchers and technologists have been focusing their efforts on the development of environmental-friendly construction materials with particular attention on the utilisation of industrial waste materials in their manufacture for sustainable development. The aim of these works is a study focused on the potential use of sand waste generated by the industrial manufacturing of zeolites in the production of SCC, so affecting the consumption of natural raw materials, water, and energy. The solid waste has been characterized by analytical techniques such as X-Ray, EDAX, and SEM, before its use in concrete production. Fresh and hardened properties of SCC have been determined. The results pointed out that waste sand can potentially used as a complementary material in SCC production. © 2014 WIT Press.
