Toxic Sludge and Char: Hidden Waste in Chemical Recycling

Chemical recycling is often promoted as a high-tech solution to plastic pollution. But behind the promise lies a darker truth: the creation of two dangerous byproducts— sludge and char . These toxic residues not only pose major environmental and health risks but are also rarely acknowledged in industry reports or public discussions. Infographic explaining toxic sludge and char from chemical recycling, their disposal methods, and environmental risks like soil contamination and air pollution. What Are Sludge and Char? 🔥 Char Char is a carbon-rich solid left over from pyrolysis (heating plastic in the absence of oxygen). It may contain: Microplastics Heavy metals Flame retardants Polycyclic aromatic hydrocarbons (PAHs) 💧 Sludge Sludge is a semi-liquid toxic residue produced during solvolysis or gasification. It’s often full of: Solvent residues Plastic additives Dioxins and other persistent organic pollutants (POPs) Undegraded plastic particles How...
