This low risk waste position (LRWP) is about treating solid waste from portable composting toilets at the depot where the toilets were hired.

If you comply with the conditions in this LRWP you can compost solid waste from portable composting toilets without an environmental permit for a waste operation.

Conditions you must comply with

You must:

  • only compost solid waste from composting toilets at the depot where the toilets were hired
  • only compost solid waste from composting toilets with a contained leakproof system that separates urine, solids and sanitary waste
  • only compost solid waste which was mixed with sawdust or shavings from virgin wood while the composting toilet was being used
  • compost solids in a secure, leakproof container at a minimum of 70°C for 1 hour or 60°C for 48 hours – the resulting compost must be stable and sanitised so it can be used for soil conditioner or fertiliser
  • only store and compost up to 10 tonnes of solid waste at any one time
  • only store up to 1.5 cubic metres of sanitary and other contaminants at any one time
  • store all sanitary and other contaminants in sealed leakproof containers, and only for up to 5 working days

  • cause a risk to water, air, soil, plants or animals
  • cause a nuisance through noise or odours
  • adversely affect the countryside or places of special interest
