Reassessing Black Plastic Coffee Makers: A Thai Perspective on Health and Everyday Convenience
A growing body of research warns that black plastic coffee machines might release cancer-related chemicals, especially when heated or repeatedly cleaned. For Thailand’s vibrant coffee scene and rising home-brewing trend, this finding hits close to home. Key concerns center on additives used in black and recycled plastics, including carbon black, brominated flame retardants (BFRs), and organophosphate flame retardants (OPFRs). Studies link these substances to cancer, hormone disruption, and neurotoxicity.
Experts note many kitchen appliances are made from recycled plastics of uncertain origin. To achieve a uniform black finish, manufacturers frequently rely on carbon black. The IARC classifies carbon black as a possible carcinogen since 2020, due to polycyclic aromatic hydrocarbons that pose cancer risks. Flame-retardant additives like BFRs and OPFRs improve fire safety but are not chemically bound to plastics, making them prone to leaching with heat or frequent cleaning. Data indicate these chemicals can migrate into beverages under certain conditions.
