  • Pathogen Inactivation by a Closed Alakaline System

    ABSTRACTThe efficiency of advanced alkaline disinfection in closed systems has been demonstrated to depend on the balance of ammonia concentration, pH, exposure time, temperature, total solids content, post-treatment storage time and mixing effectiveness. When the alkaline system is a closed one, an additional pathogen stressor is added: pressure. The effect of the alkaline dosing has been ...

  • Mixed MSW composting in transition

    WITHOUT a doubt, composting the mixed municipal solid waste stream is a “niche” business. It is an MSW management option that seems to be viable in very specific situations.
