A wnaiff y Gweinidog gadarnhau pa dystiolaeth sydd gan Cyfoeth Naturiol Cymru i gefnogi ei benderfyniad i roi'r gorau i ddefnyddio ffibr carped mewn arwynebau marchogol?
Natural Resources Wales’ (NRW) withdrew their Low Risk Waste Recovery Operation (LRWRO) [allowing a waste activity for which there is no current exemption covered in the Environmental Permitting Regulations] due to the risk that using carpet fibre can introduce Persistent Organic Pollutants, microplastics and microfibres into the environment. For example a study on Toxics in Carpets, produced by Anthesis Consulting Group PLC identified a list of 59 toxic substances used in carpets. NRW are therefore undertaking further work to understand the nature of Persistent Organic Pollutants in this waste stream.
