Ten things you must know about: Waste King's fluorescent bulb recycling process

Fluorescent lightbulbs are the best and resilient lightbulbs available now. With the move toward more energy efficiency and environmental duty, fluorescent lights have become more common fixtures worldwide. Below are some of the important things that you have to know about Fluorescent lightbulbs:

Waste King's nine-step fluorescent bulb recycling procedure is:

The approximate capacity for one inch fluorescent tubes, of a coffin, is 150 x 6ft or 450 x 2ft tubes.

The container with the lamps that were spent is collected and taken to Waste King's website for sorting, prior to being recycled.

The Skip Hire Harpenden container is put into the site storage area to await processing.

For processing in a crush and separationplant waste King loads the lamps onto racked trolleys.



The plant is fully automatic. It enables processing of sizes and the various types of lamps, splitting them into phosphor powder, aluminium end caps, lead glass /ferrous metal parts and soda lime glass.

The crush and sieve plant works at sub-pressure, thereby preventing mercury from being released into the surroundings as exhaust air (which will be always discharged through the internal carbon filters).

The entire crush and separation plant is featured in a container where the tubes are fed by a conveyor to some hammer mill. The ensuing fractions that are joined are air-carried through a separation tower, where the glass and metal are removed. The metal and glass parts are then crushed further and air-carried to a second separation tower. Glass resulting from the sieving operation (after the first separation tower) is smashed farther and air-conducted through a third separation tower. The glass fragments are fed to a rotary drum-feeder and transferred to a discharge conveyor to transfer the by-product out of the processing unit.

The air stream that has passed through the separation towers features phosphor powder.

This air stream passes through a cyclone, where the powder is accumulated in a distiller barrel, and then passes through two dust filters, where the remaining dust deposited in distiller barrels and is removed. The air stream then passes through four- carbon filters to remove any mercury vapour before passing into the atmosphere via a vent that is combined.

Aluminium, found glass and metals are sent to other firms to be used as raw materials or for additional processing.

Every time a ‘coffin' has filled with fluorescent tubes that are spent, Waste King's operatives will arrive, accumulate the the entire procedure and the container continues.
