Domestic appliance manufacturer Crosslee and garden product producer Gardman are the latest recruits.
Gardman chairman Paris Natar said: As the UK market leader for garden sundry products we take our environmental responsibilities seriously. So joining REPIC was a straightforward decision for us. While electrical and electronic products are a small but important part of our customer offering, they are growing rapidly and we need to ensure that Gardman fulfils its obligations under the new law.
REPIC says it welcomes all companies that have an obligation under the new law, no matter how large or small.
