As part of processing trees, greenwaste, timber and pallet waste, regardless of the site, the product produced can be used as raw mulch, screened or regrinding, to make it into a variety of products which will save it from being used in landfilled (historically a very common outcome for processed material).


It is important to understand that there are many different types of mulch which can be generated, depending on the grinder screens, type of product being processed and the clients required outcome.


Products can include:

  • Fresh mulch – (straight from the truck) and processed by small tree woodchippers – generally given away for free (or for a small delivery fee).
  • Forest mulch – mulch that has been aged to ensure there is no nitrogen drawdown. This is the most popular form of mulch for home owners who are happy to spend the money or who like the look of a deep brown coloured
  • Forest regrind – this product has been screened, through grinding to less than 100mm in size. Ideally, this product can be used for large gardens (cost effective) or can be used for soil erosion control measures.  This product can be generated by taking fresh mulch, ageing it and then regrinding through a horizontal grinder.  By using the 100mm screen, or smaller, it ensures a most consistent product size.
  • Forest fines – this is a fine product that has gone through the Forest Regrind process as above, however, is screened through a finer sized screen – generally less than a 20mm screen. Due to processing the product this way it is generally light and fluffy in texture, with colour variation depending on material used, water density and maturation of the product being processed.
  • Tub mulch – generally a very coarse mulch, straight from the horizontal grinder where the product can vary in size due to using larger screens. Depending on the type of job, this is the type of product which would generally be generated when land clearing.  It would also contain dirt from feeding rootballs and stumps through the grinding process at the same time.
  • Tip mulch – due to the unregulated source (mum’s and dads garden waste), tip mulch is processed on council sites and would be pasteruized to remove pathogens. Product can vary in size due to screening and colour due to water density, age and original material dumped, which may include large volumes of green material, rather than more majorly timber products.
  • Straight tip mulch – this is a non-regulated waste product that would generally be provided to specific sites, these could include power station fuel or meat works processing facilities. These sites would require their own licences and permits specific to allow the receival of these products.
