During many industrial processes, contaminated residues that could pollute the environment are produced. These residues can include:
- Ash from incinerators
- Slag from metal production
- Sludges from purification plants and sewage treatment plants
- Filter dust
- Contaminated soil
Usually these residues are deposited in landfills, at a high cost. However, through the process of immobilization, residues can be altered so they are transformed into environmentally safe products that can be used as building materials.
Contaminated residues are immobilized by binding them with a substance, such as cement. Binding captures pollutants, so the waste material is no longer a threat to the environment. In addition, binding changes the material's chemical properties, so it can be used in construction. For example, immobilized waste material can be used in:
- Concrete blocks
Immobilization not only allows you to reuse your waste material; it enables you to save money by avoiding removal fees.
We provide advice, testing and support regarding immobilization, so you can be sure that contaminated residues are being put to best use.
Why choose immobilization services from SGS?
We work with industries that produce substantial amounts of residue and could benefit greatly from immobilization. We also work with businesses that have already developed their own immobilization or other waste treatment techniques. We offer:
- Advice on recipe development
- Assessments of applications of building materials created from immobilization
- Suggestions for new uses of immobilized residues
- Laboratory testing, including leaching, compression strength and durability testing, to ensure legal and environmental requirements are met
Unmatched experience in immobilization services
We have many years of experience working with immobilized materials, so you can depend on us to provide you with the advice and assistance that you need.
