Ten things you have to know about: Waste King's fluorescent bulb recycling procedure

Fluorescent bulbs are the most effective and resilient bulbs available today. With the move toward more energy efficiency and environmental responsibility, fluorescent lights are becoming more common fixtures internationally. Below are some of the important matters which you should 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 6feet or 450 x 2ft tubes.

The container with the spent lamps is collected and taken to Waste King's website for sorting.

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

The lamps are loaded by waste King for processing in separationplant and a crush.



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

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

The entire crush and separation plant is featured in a container in which the tubes are skip hire Hitchin fed by a conveyor to some hammer mill. The resulting fractions that are joined are air-carried through a separation tower, where the glass and metal are removed. The glass and metal components are subsequently smashed further and air-carried to a second separation tower. The glass fragments, removed by the third separation tower, are fed to a rotary drum-feeder and transferred to your discharge conveyor to transfer the by-product out of the processing unit.

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

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

Recovered glass, aluminium and metals are sent to other firms for use as raw materials or for additional processing.

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