Dead people's artificial joints are being recycled across the UK under a scheme launched this month.
The Institute of Cemetery and Crematorium Management (ICCM) has delivered collection bins to 41 local authorities.
Metal from cremated bodies will be collected and sent to a smelter in Sheffield to be reprocessed.
ICCM chief executive Tim Morris said: "At the moment, metal implants are disposed of in pits at crematorium sites.
"Our bins are purpose-made and collected in person with dignity and respect. We always have written permission from relatives.
"We have modelled the scheme on one in operation in Holland where Ortho Metals collects metal from crematoria.
"Our scheme has only been running for two weeks but we already have authorities giving out consent forms."
