Solid Waste Testing

Improper disposal of solid waste can cause serious harm to human health and even result in irreversible damage to the environment. Therefore, testing is the primary task for the prevention and control of solid waste pollution. The CTC Solid Waste Laboratory is dedicated to the analysis, testing, and identification of the leaching toxicity of solid waste. Leveraging the Group’s strengths in building materials and environmental testing, the laboratory has assembled a lean and professional team for hazardous solid waste testing, comprising professor-level senior engineers, senior engineers, doctors, and masters. It has been accredited by the China National Accreditation Service for Conformity Assessment (CNAS) and has received national metrology certification (CMA). It is one of the earliest and most authoritative solid waste testing laboratories in China.
