How Can Thin Film Technology Solve Landfill and Waste Reduction Issues?
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.
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

Reduce Hazardous Solvents in Waste Streams
- Oils & various hydrocarbons
- Volatile Organic Compounds (VOC’s)
- Battery & electronic waste
Concentrate Residues
- Tar & Paint sludge
- Leachate streams
- Salt solutions
- Drilling Residues
Drying Various Municipal & Industrial Sludge Streams
- Coal slurry
- Biomass
- Contaminated soil
- Industrial process waste
