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

Fluorescent bulbs are the most efficient and long lasting lightbulbs today accessible. With the move toward more energy efficiency and environmental responsibility, fluorescent lights are becoming more common fixtures internationally. Below are some of the matters that are important that you have to understand about Fluorescent lightbulbs:

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

Waste King delivers a specially constructed container – known as a ‘coffin' - to the customer's premises for the safe collection and storage of spent lamps. The approximate capacity for one inch fluorescent tubes, of a coffin, is 150 x 6ft or 450 x 2ft tubes.

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

The container is placed in the site storage area to await processing.

Waste King loads skip hire leighton buzzard the lamps onto trolleys that are racked for processing in separationplant and a puppy love.



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

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

Separation plant and the whole crush is comprised in a container in which the tubes are fed by a conveyor into a hammer mill. The resulting fractions that are joined are air-carried through a separation tower, where metal and the glass are removed. The glass and metal components 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 further and air-carried through a third separation tower. The glass fragments are fed into a rotary drum-feeder and transferred to a discharge conveyor to transfer the byproduct from the processing unit.

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

This air stream passes through a cyclone, where the powder is accumulated in a distiller barrel, and after that passes through two dust filters, where the remaining dust deposited in distiller barrels and is removed. 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.

Found glass, aluminium and metals are sent to other companies to be used as raw materials or for additional processing.

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