Service overview

When you need this service

  • You are planning a new project or operation expansion
  • The regional authority or EIA requires a dispersion study
  • You need to compare technical solution variants
  • You are changing the source, capacity, fuel, transport or emission parameters

What we provide

  • We model immission contribution of stationary sources and transport on site
  • We assess operational variants and technical measures
  • We evaluate impacts on surrounding development
  • We prepare studies for boilers, landfills, recycling, biogas, glassworks and paint shops

What you receive

  • dispersion study with conclusions and recommendations
  • variant assessment (if part of the brief)
  • documentation for the investor, designer and authority

How to get started

For an initial scope assessment, please send:

  • source parameters and emission data
  • operating schedules and transport on site
  • project layout and map documentation

Additional information for preparing your inquiry

Practical project examples

  • dispersion study for a new or modified air pollution source
  • dispersion study for a landfill, recycling site or composting facility
  • assessment of a boiler, paint shop, biogas plant or glassworks

Typical mistakes and risks

  • Outdated emission data or operating schedules
  • Study without variant assessment for capacity change
  • Insufficient map and transport documentation

FAQ for this service

When is a dispersion study required?

Prepare a dispersion study for a new or modified emission source, technology change, capacity increase, EIA, permitting proceedings or on instruction from the regional authority.

Who may prepare a dispersion study?

A dispersion study may be prepared by an authorised person within the relevant scope.

What documentation is needed for a dispersion study?

Typically a technology description, emission parameters, stack height and diameter, volumetric flow, temperature, operating hours, site layout, transport data, surrounding development data and the study purpose.

Can a dispersion study be prepared for variants?

Yes. For projects in preparation, multiple technology, stack, operating mode, capacity or transport intensity variants can be compared. Variant assessment helps the investor and designer find a technically and environmentally preferable solution.

When is a noise study appropriate?

A noise study is appropriate before implementing a new noise source, during technology change, for industrial sites, HVAC, heat pumps, transport, storage and production operations, or as documentation for building proceedings, KHS or EIA.
