WHAT ARE PCBs?
Polychlorinated Biphenyls (PCBs), which were first manufactured in the 1900’s, are oily liquids that may be found in old electrical transformers, capacitors, fluorescent ballasts, liquid-filled circuit breakers and voltage regulators. It has also been used as flame retardant, paint stabilizer, plasticizer, and in carbon-less paper.
PCBs are Persistent Organic Pollutants (POPs). These chemicals do not break down easily, remain in the environment and continue to build up. They were banned from use before the 1980s due to their toxicity and were listed among the priority POPs targeted for global elimination under the Stockholm Convention on POPs, a global agreement ratified by the Senate of the Philippines.
WHAT IS E-WASTE?
E-Wastes or electronic wastes are broken, spent, obsolete and unwanted electronic and electrical products requiring disposal.
An E-Waste, also referred to as Waste Electrical and Electronic Equipment (WEEE), if improperly managed, such as through improper dismantling, burning or disposal can result in the release of harmful chemicals into the environment, among which is Polybrominated Diphenyl Ethers (PBDEs).
PBDEs are a class of chemicals that are used as flame retardant in electronic and electrical products, like TVs and laptops. They are also used in other easily combustible products, like furniture, mattresses, textiles, vehicle polyurethane foams and plastic parts, and others.
