Evaluating Degradation Mechanisms in Post-Consumer Polyolefin Flake
Polyolefin degradation evaluation requires coupling multi-load melt flow testing and OIT analysis to quantify chain scission and restabilize flake lots.
Post-Consumer Resin Pricing
Meaning
Secondary material markets determine the financial feasibility of using recycled plastics in place of virgin resins. The post-consumer resin pricing structure is governed by sortation costs, regional supply, and the global price of crude oil. This pricing model dictates whether manufacturers can meet sustainability goals without incurring a cost penalty.
Sortation Premium
Recycled plastics must be collected, sorted by polymer type, and washed to remove contaminants before they can be pelletized. This intensive labor and processing cost creates a floor price that does not exist for virgin resins. When sortation capacity is limited, the price of clean recycled pellets rises regardless of the cost of virgin material.
Supply Elasticity
Availability of high-quality recycled feedstock depends on municipal collection programs and consumer behavior. This supply is often inelastic, meaning that a sudden increase in demand from brand owners cannot be met by a rapid increase in collection volume. The resulting supply deficit drives up the market rate for certified grades of recycled resins.
This inelasticity is particularly severe for food-grade recycled polymers, where the rigorous regulatory requirements further restrict the number of approved recycling facilities.
Virgin Spread
Manufacturers compare the cost of recycled pellets directly to the price of prime virgin polymer. If the price difference is too narrow, some moulders revert to virgin material to avoid the processing challenges associated with recycled resins. This relationship makes the economic viability of recycling highly sensitive to fluctuations in the petrochemical market.
