Non Hazardous Soil Washing

Our wet processing equipment extracts maximum value from non-hazardous soil and excavation waste materials.

Proven Solutions Engineered for Soil Washing

CDE’s proven soil washing equipment provides savings on landfill charges, prevents extra investment in waste storage equipment, and produces new materials for reuse.

Soil washing involves the recovery of a range of materials from soils, often extracted from excavation waste sites. Depending on your location you may also refer to this material as muck away. This material, traditionally considered waste, contains valuable materials that can be extracted, cleaned, and reused.  

Every soil washing plant from CDE is unique and designed specifically with the customer’s site, material and desired product outputs in mind.

CDE’s soil washing equipment not only increases the efficiency of your operations but also reduces your company’s carbon footprint by producing recycled sand and aggregates closer to market.

Our technologies utilise a suite of mechanical, chemical, and biological processes for recovering washed solids such as sand and aggregates.

Typically a number of process phases are involved, including:

  1. Feeding & pre-screening
  2. Aggregate scrubbing
  3. Sand washing
  4. Aggregate sizing
  5. Primary stage water treatment
  6. Sludge Management

CDE also provides solutions for contaminated soils which includes additional treatment stages.

Our non-hazardous soil washing equipment produces a range of sizes of sand and aggregates depending on your requirements. In doing so, customers reap the following benefits:

  • The materials can be sold for reuse as a replacement for natural materials in a range of construction applications including concrete and asphalt production, pipe bedding and road subbase, or used on site for the same purposes.
  • The ability to meet growing demand for sand and aggregates from a sustainable source.
  • The reduction in transport costs for sand and aggregates as recycled materials are typically produced closer to urban centres.
  • The reduction in the carbon footprint of your processing operation.
