Waste Classification & Analysis

Waste Classification and Services


A. D. Envirotech Australia Pty Ltd provides waste classification and services to individuals and companies that generate waste and require assistance in determining the waste class in accordance to the classification approved by the NSW EPA in accordance with the NSW DECCW Waste Classification Guidelines.


The classification of waste into specific groups that pose similar risks to the environment and human health allows for appropriate management and disposal at licensed landfills.




There are 6 main ways that waste can be classified in NSW:


  1. Special Waste – clinical and related waste, asbestos waste, waste tyres
  2. Liquid Waste –  has an angle of repose of less than 5 degrees above horizontal, become free flowing at or 60 degrees Celsius or when transported, is generally not capable of being picked up by a spade or shovel
  3. Hazardous Waste – containers previously containing a substance of 1,3,4,5 or 8 as explained by the Transport of Dangerous Goods Code, coal tar waste, lead-acid or nickel-cadmium batteries, lead paint
  4. Restricted Solid Waste – The highest classification of solid waste though the EPA has not issued a list of pre-classified items to identify them.
  5. General Solid Waste (putrescible)  – household waste containing putrescible organics, waste from garbage bins collected by the Council, manure, disposable nappies, food waste, animal waste etc
  6. General Solid Waste (non-putrescible) – glass, plastic, rubber, bricks, concrete, paper, cardboard, garden waste, synthetic fibre waste, virgin excavated natural material (VENM) etc


In addition, the EPA issues general exemptions for commonly recovered, high volume and well characterised waste materials for recycling or disposal.


The most common Exemptions include:
