Climate change, sustainability, and cost savings are all pointing to one main international need for plastic manufacturing: the effective use of recycled post-consumer materials. One sustainable remediation to this concern is the use of post-consumer materials in an ever growing stormwater management market. Specifically, the opportunity for use of high percentage postconsumer recycled materials in plastic pipe offers a viable solution to plastic waste management concerns in a market with healthy growth potential. The use of 100% post-consumer materials in plastic pipe manufacturing is riddled with numerous challenges for the production of a uniform, high quality product that is cost effective. However, blending post-consumer materials with either virgin resins or high quality post-industrial products provides the best means of achieving these three key international goals. This blending, however, must be targeted to the application of the product, and as such, the key design aspects of each end use for the pipe must be identified. Stress crack resistance, long-term mechanical properties, oxidation and service life all play a part in selecting the appropriate blending characteristics for manufacturing plastic pipe for a specific application. The availability and the consistency of recycled materials create a difficult problem for assessing the acceptability of this material for mass production of high quality products for various applications. The key to this issue is balancing the engineering and service life requirements to the specific end applications, which range from residential landscape drainage products to high end sanitary sewer projects. This paper provides an overview of blending criteria that must be addressed for these applications and the production means of achieving these requirements.

The use of recycled plastics in high density corrugated polyethylene pipe for storm sewers, highway culverts and general land drainage applications has now been widely accepted by municipalities and transportation agencies. This acceptance has made it possible to convert what was once considered a single use plastic...

Corrugated HDPE pipes have been successfully used for decades for sewers, culverts and land drainage applications and are advantageous due to their durability and service life in a variety of installation conditions. Pipes used for highway and storm sewer applications typically require stricter material standards than...

A great deal of attention has been paid in recent years for the development of sustainable products with zero waste. At the core of many of these discussions has been the utilization of recycled plastics. One of the largest outlets or utilization of recycled thermoplastics, specifically high density polyethylene...

Major standards organizations, such as ASTM International, ISO (International Standards Organization) and AASHTO (American Association of State Highway and Transportation Officials), have a test method for evaluating a plastic pipe’s wall stability and load capacity. The name of the performance test may be called...
