Paints are mixed with other waste solvents and used as an alternative to fuel in cement kilns. The metal containers are recycled.
Used oils are processed to become a lubricant or used for waste-to-energy.
Gas bottles have residual gas captured for reuse. Undamaged bottles are retested, restamped and entered into the hire industry. Damaged bottles are punctured and recycled as scrap metal.
Lead acid batteries are sent to recyclers where the lead, acid and plastic are recovered and recycled.
Fluorescent tubes and globes contain mercury. Recyclers crush the tubes to separate the phosphor powder from the glass. They feed the powder through receiving containers, where it is filtered to capture fugitive mercury emissions. The mercury is then separated by distillation and sold for a range of industrial uses. The metals are also recycled.
X-ray films are processed to extract the silver, which can then be reused for things such as silver solder, jewellery, the silver plating of utensils, electrical components and film manufacture.
Printer cartridges are made up of a complex mix of plastics, metal, inks and toners. The collected cartridges are returned for remanufacturing or recycling into new products, such as outdoor decking, fencing, garden beds, pens and ink.
