Historically, solid waste landfills have been the preferred
method of waste disposal due to their hands off approach,
simplicity, low cost & acceptance of a variety of wastes.
However, landfill disposal regulations have increased to
reduce landfill waste, environmental impacts & health
concerns, including:
- Landfill stability & slope failure
- Greenhouse gas emissions from organic matter
- Lengthy decomposition of certain materials
- Pressure to recycle materials
- Waste to energy implementation
- Concerns from leaching, off-gassing, & flammability of hazardous materials
- Limited space with few new landfills permitted
In some cases, these concerns eliminate landfilling as a
waste disposal option.
In other cases, where landfills accept these waste streams,
stricter specifications or higher costs are more common. To
reduce costs & adhere to regulations, thin film evaporation
& drying have been utilized to drastically reduce the mass
& hazardous content of waste streams.
Reduce Liquid Waste & Treat Water Waste
- “Zero liquid discharge” technologies (ZLD)
Reduce Hazardous Solvents in Waste Streams
- Oils & various hydrocarbons
- Volatile Organic Compounds (VOC’s)
- Battery & electronic waste
Concentrate Residues
