Noise Assessment - Solid Fuel Recovery Process Plant

Project Description: 

TNEI has been commissioned to undertake an environmental noise impact assessment (NIA) in order to support the PPC Part A permit application for a Solid Fuel Recovery (SRF) process plant in Perthshire. The SRF process is an advanced fuel preparation process which takes fine residual waste from existing recycling facilities that is currently landfilled. After drying, the material is processed to remove over-sized waste and separation of all ferrous and non-ferrous metals prior to shredding and baling.

The NIA comprises of two elements; firstly, a comprehensive noise source inventory is compiled and an assessment made against BAT (best available techniques). Compilation of the inventory will comprise a mixture of analysis of manufacturer supplied noise and test data and on site noise level measurements. Secondly, an assessment of noise levels received at the nearest noise sensitive receptors is undertaken through a series of operational noise levels measurements and comparison made against noise level limits derived from existing background noise levels.

Key Features:
  • Potential waste throughput of 200 tons per day;
  • Waste is dried for 48 hours – it’s placed in concrete bays and a large boiler and fan system blows warm air up through the floor;
  • Main noise sources for drying include roof and high level mounted fans, chimney stack, large centrifugal fan and mobile plant (telehandler) for movement of materials. All fixed plant operates 24hours a day;
  • Main noise sources for SRF processing including conveyors, over-band magnets and eddy current separators, shredder and bailing machinery;
  • Report / PPC permit application will be submitted to SEPA;
  • Relevant noise guidance docs are IPPC H3 Horizontal Guidance for Noise Parts 1 and 2; and
  • Assessments will be made against BS4142:2014 Methods for rating and assessing industrial and commercial sound.
