| | Waste and Sludge Analysis | |
C.B.A. Chimica Biologia Ambiente performs waste analysis for classification, confirmation of the EWC code, and assignment of risk classes to ensure proper disposal. Waste analysis is mandatory in many cases for landfill disposal, recovery, and transportation. These analyses determine the nature, composition, and chemical-physical characteristics of the waste and assign it the correct risk class—information that is essential for proper waste management, thereby preventing risks to the environment and public health. Furthermore, these analyses can help reduce waste disposal costs by identifying the most efficient and cost-effective solutions.
Our laboratory is committed to providing high-quality services to ensure responsible and environmentally sound waste management. Our services include sample collection, chemical and physical analyses, and, when necessary, microbiological analyses. The results of the analyses are issued with a certificate compliant with current regulations. |
Characterization
Analysis Chemical characterization analyses of waste as is are used to determine the chemical composition of a waste sample. These analyses are used to identify the presence of any hazardous or toxic substances and to assess contamination levels. Characterization analysis is essential for so-called mirror wastes—that is, when there is both a hazardous and a non-hazardous EER/CER code. | Leaching
Test The analysis of a waste eluate (also known as a leaching test) allows for the assessment of a waste’s stability and hazardousness during management and disposal. This test determines whether a waste stream is safe to handle, whether it can be recycled, or whether it must be disposed of safely. The test involves a solid-liquid extraction process, in which the sample is immersed in a solvent (distilled water) for a typical duration of 24 hours. The subsequent analysis of the chemical compounds released into the resulting eluate aims to quantify the fraction of soluble contaminants present in the solid sample. This test is useful for assessing the environmental risk associated with the waste by identifying chemicals that could contaminate groundwater and soil. The leaching test is required, in particular, to verify the waste’s eligibility for landfill disposal. Obviously, it is not possible to obtain an eluate from liquid waste; therefore, the leaching test applies only to solid waste. | |
Confirmation of the EER/CER
Code Each waste stream must be analyzed to confirm the correct assignment of the EER/CER code assigned to the waste by its producer and, in the case of non-hazardous waste, to rule out the presence of substances that could render it hazardous. Following the analyses, the laboratory will issue a certificate containing an assessment of the waste under investigation, indicating its potential hazardous nature and the confirmed EER/CER code. | |
Assignment of Hazard
Characteristics In the certificate issued by the laboratory for hazardous waste only, based on the analytical results obtained, the hazard characteristics—known as hazard classes—will be indicated, denoted by the codes HP1 through HP15. These are extremely important for the proper management of hazardous waste during transport and disposal operations. | |
