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

Fluorescent lightbulbs are the most effective and long lasting lightbulbs available now. With the move toward more energy efficiency and environmental duty, fluorescent lights have become more common fixtures internationally. Below are some of the significant matters which you should know about Fluorescent bulbs:

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

Waste King delivers a specially designed container – known colloquially, 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, is 150 x 6ft or 450 x 2ft tubes.

The container with the lamps that were spent is gathered and taken to Waste King's site for sorting.

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

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

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

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

Separation plant and the whole crush is incorporated in a container in which a conveyor feeds the tubes into a hammer mill. The resultant combined fractions are air-conveyed through a separation tower, where the glass and metal are removed. The glass and metal parts are then smashed further and air-carried to another separation tower. The glass fragments, removed by the third separation tower, are fed to a rotary drum-feeder and transferred skip hire oxford to a discharge conveyor to transfer the byproduct out of the processing unit.

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

This air stream passes through a cyclone, where the powder is collected in a distiller barrel, and after that passes through two dust filters, where the remaining dust is removed and deposited in distiller barrels. 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 recovered glass and metals metals are sent to other companies for use as raw materials or for further processing.

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