Why use SILO Bin partly or totally Underground Solid Waste Collection?


  • Less than 40% of the bin is visible on the surface the rest is underground
  • The above surface parts of the SILO can be adapted to fit into the surrounding area. Various colour and wood/aluminium framing options are offered
  • 4 to 5 times greater collection volume for a given surface area compared to traditional surface bins
  • Different types of waste can be collected in a smaller surface area
  • Due then design of SILO the effect of gravity causes compaction of the waste material, increasing the yield by around 20%



  • Service truck traffic is reduced thus reducing, emissions, costs, congestion and noise
  • The vertical design means that the SILO is filled evenly which is not the case with other high volume containers
  • Because of the even filling old waste is covered with new waste which helps to prevent odours
  • The ground temperature around the SILO is always much lower than the air temperature which slows bacterial growth and odour
  • SILO emptying intervals are longer due to the greater volume and increased hygiene

  • SILOs are emptied by lifting out the lining bag which empties from the bottom of the bag, this helps keep the filling area cleaner
  • SILO location can be designed to be optimal for both users and collection company
  • Increased hygiene allows the SILOs be installed more freely, with reduced risk of disease to the users and service operators
  • The filling orifice is shaped according to the waste material that is to be collected
  • The filling lid is light and closed automatically preventing a animals from getting into the waste
  • Places like car parks, picnic areas etc where there will be large seasonal variation can be more easily catered for due to the high volume, longer emptying intervals of SILOs
  • SILO’s heavy duty structure means the that they are virtually maintenance free
  • SILO’s fixed nature means that they are not susceptible to strong winds
  • Experience has shown that where SILOs have been installed the recycling area tends to be kept much tidier
  • SILOs do not need not be hidden behind fencing due to their more aesthetic look
  • SILO can be utilised for all types applications; Local Recycling Centres, Golf Courses, Hotels, commercial enterprises, Public Parks, Beaches, Housing Estates, Apartment blocks, etc

Specific benefits for paper collection:

  • Watertight body and lid means that collected paper is less likely to become damp and mouldy, dry mould free paper is much easier to de-ink in the recycling process, generally the quality of paper remains high

Specific benefits for glass collection

  • Less frequent emptying, less noise (ground absorbs the noise), less overfilling problems
  • Liquid proof wells stop waste liquid from the glass contaminating the ground
  • The glass can be collected broken or whole depending on market
