What is rHDPE (Recycled High-Density Polyethylene)?
rHDPE (Recycled High-Density Polyethylene) is a sustainable polymer material produced from post-consumer and post-industrial HDPE waste through sorting, washing, melting, and pelletizing processes.It retains most of the mechanical and chemical properties of virgin HDPE while significantly reducing environmental impact and material cost.
Today, rHDPE is widely used in drainage pipelines, municipal infrastructure, agricultural systems, and industrial fluid transportation.
As global industries move toward circular economy and low-carbon materials, rHDPE has become an increasingly important alternative raw material for pipe manufacturing.
