The answer

Open windrow compost sites produce emissions which are dangerous to people and animals. The only way to curtail this risk is to reduce exposure.

We believe some in-vessel sites, (where the emissions and odours are contained and the air is scrubbed using biofilters before being released) are working well and not exposing residents to odours or health hazards. However, there are also some in-vessel sites that are clearly a complete nightmare and often theso-called in-vessel stage is simply a ‘sanitisation’ process with the material being turned out into open windrows for ‘maturation’.

Whether there are problems seems to depend on a number of key aspects:

  • The technology used
  • The investment up front
  • The location of the site
  • The degree of enclosure (maturation heaps seem to be causing major problems)
  • Who the operator is and
  • Whether throughput is maintained at reasonable levels

Many operators are describing proposed facilities as in-vessel when it is clear they are not.
ALWAYS get an expert view on any proposed facility.

Really the Government needs to go back to the drawing board on composting and provide further advice and guidance on the best technologies available and certainly provide stricter guidelines on all the items listed above. There are also some alternative proposals being put forward on how to deal with green waste compost . Have these recieved proper evaluation?

Anaerobic Digestion seems to be flavour of the month but this too can cause problems if not cariied out to very high standards.

If the Government fails to make changes our group could help create a rubbish revolt!
