We need to talk about light bulbs. For years we’ve all been busy replacing traditional energy-hungry incandescent light globes around our homes and offices with those ubiquitous compact fluorescent lamps (CFLs).
Certainly they use only a fraction of the power, and that’s great for household budgets and as a carbon pollution reduction measure. But unless the used CFLs are diverted from landfill to a properly qualified recycler, the pollution risks are high. The main worry is mercury – a notorious heavy metal that brings with it serious health and environmental risks.
