RoHS stands for Restriction of Hazardous Substances and is an EU directive limiting the use of certain hazardous materials in electronics.

The RoHS directive was enacted in 2003 to address environmental concerns linked with electronic waste. It restricts the presence of ten specific substances, including lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr VI), polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE). These materials can cause significant environmental damage if not properly disposed of. The directive sets a limit for each substance, ensuring that electronics don't exceed these thresholds. For example, the lead content must be less than 0.1% by weight in most components.

A real-world application of RoHS is seen in smartphone manufacturing. Before phones hit store shelves, manufacturers must ensure that they don't contain any banned substances above the allowed limits. Companies like Apple and Samsung have adapted their supply chains to comply with RoHS requirements, which means using alternative materials for soldering, circuit boards, and other components.

According to the WHO, e-waste contains over 1,000 different substances, many of them toxic.

For consumers and businesses, adhering to RoHS standards is important because it ensures safer products and minimizes environmental impact. When buying or selling electronics, knowing that a device complies with RoHS gives peace of mind about its safety and sustainability. Additionally, recycling centers often rely on these standards when handling e-waste, ensuring proper disposal methods are used.

RoHS aligns closely with other important regulations like WEEE (Waste Electrical and Electronic Equipment Directive), which focuses on the collection and recycling of electronic waste. Both directives work together to create a more sustainable electronics industry that protects human health and the environment.

According to the European Commission's data, RoHS compliance has led to significant reductions in hazardous substance use across Europe, with over 90% of electrical goods meeting the directive's requirements as of 2018.

According to the UN Global E-Waste Monitor 2024, only 22.3% of e-waste was properly collected and recycled in 2022.
