Abstract
In recent years the incorporation of waste plastic into fibres intended for geotextiles has attracted interest as aesthetic requirements are not considered important. However the addition of waste material to virgin polymers raises questions of durability. In this paper the addition of waste HDPE to PP to produce fibres that were subsequently subjected to accelerated thermal ageing is described. Compared to PP fibres containing virgin HDPE the fibres containing the recycled HDPE had poor durability. However, addition of a recycling stabiliser package (Recyclossorb 550) resulted in much improved durability albeit at the expense of drawability.
