The Bulb Recycling Process
Bulb Recycling in London and the UK
The mercury powder is distilled on-site. The appropriate programme is selected and the distillation process begins. A vacuum is applied to the unit. The after-combustion chamber and process chamber are then electronically heated. Any organic content in the resulting vapour is oxidised in the after-combustion chamber and the mercury vapour is condensed, in a condenser, which is cooled by a chilled glycol refrigeration unit. The condensed mercury is removed from the collection chamber and stored before being despatched as a product.

The Bulb Recycling Details
Bulb Recycling within the UK
The nine-step Bulb Recycling process is:
A specially designed container is delivered for the safe collection and storage of spent lamps.
The container with the spent lamps is collected and brought back to Waste Kings site for sorting, prior to being recycled.
The container is placed in the site storage area to await processing.
Waste King loads the lamps onto racked trolleys for processing in the crush and separation plant.
The plant separates them into soda lime glass, aluminium end caps, lead glass/ferrous metal components and phosphor powder.
The crush and sieve plant operates at sub-pressure, thereby preventing mercury from being released into the environment as exhaust air.
The entire crush and separation plant is incorporated in a container in which a conveyor feeds the tubes to a hammer mill. The glass and metal parts are then crushed further and air-conveyed to a second separation tower.
Glass resulting from the sieving operation is crushed further and air-conveyed through a third separation tower. The glass fragments, removed by the third separation tower, 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 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.
Recovered glass, aluminium and metals are sent to other companies for use as raw materials or far further processing.Contact us
