Our Guide to Safe Hazardous Waste Disposal

Believe it or not...your home is probably full of hazardous waste. Many products we use regularly everyday (cleaners, glues, soaps, pesticides, pharmaceuticals) are toxic or hazardous. If these products are used improperly, carelessly, or in a manner not intended, they can injure you both directly and indirectly. By putting these into your trash can, you endanger refuse collectors, the environment and our drinking water. You are ultimately liable for these wastes and any harm they cause.
