    The use of regenerative thermal oxidizers is expanding into applications where they wouldn’t have been considered years ago, says Mike Scholz As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking ...

  • An end to the problem of particle emissions

    Austrian biomass heating systems guarantee an 80% cut in emissions. Recent studies have shown that these modern domestic boilers offer a significant reduction in particles, emitting fewer contaminating agents than previous generation boilers and wood stoves – with more than 100mg / ml of particles. The future will be based on new biomass combustion technology which cuts dust emissions from ...

  • Tackling remediation emissions

    Organisations commissioning regeneration projects now have the option to substantially reduce the carbon emissions associated with any remediation project, while offsetting the remaining carbon impact of these works, says Joe Teer, operations director of QDS. QDS introduced a carbon neutral remediation (CNR) service earlier this year triggered at this particular time by the fact ...
