      This paper presents an analysis of the representativeness of the main laboratory tests and the real dura-bility of earth-based construction materials. For this study, a natural marl soil, mixed with different per-centages ...
    • Feasibility of vermicomposting of spent coffee grounds and silverskin from coffee industries: a laboratory study 

      González Moreno, Miguel Ángel Upna Orcid; Marcelino Sádaba, Sara Upna Orcid; Zaratiegui Urdin, Javier Upna; Robles Domínguez, Estrella Upna; Pérez Ezcurdia, Amaya Upna Orcid; Seco Meneses, Andrés Upna Orcid (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      In the coffee industry, several by-products are generated during the production and consumption of coffee and represent an important waste from an environmental viewpoint. For improving the knowledge about this issue, a ...
    • Low energy spent coffee grounds briquetting with organic binders for biomass fuel manufacturing 

      Espuelas Zuazu, Sandra Upna Orcid; Marcelino Sádaba, Sara Upna Orcid; Echeverría, Angel María Upna Orcid; Castillo, Jesús María del Upna Orcid; Seco Meneses, Andrés Upna Orcid (Elsevier, 2020)   Artículo / Artikulua
      This paper analyzes the ability of the spent coffee grounds (SCG) for briquettes production with xanthan and guar gums as binders. Briquettes were manufactured at room temperature, at 15%, 20%, 25% and 30% of moisture, at ...
    • Magnesium oxide as alternative binder for unfired clay bricks manufacturing
