Is the use of virgin material a cheaper alternative than a purge compound?

With respect to sustainability, purging with virgin material is the worst approach. Compared with purging compounds, the cleaning performance of virgin polymers is poor, and the amount of scrapped material, time, and energy consumption is significantly higher. Using specialized purging compounds saves considerable time and energy between the last quality part produced in previous resin or color and the first quality part following. Using a specialized purging compound on machines typically purged with virgin polymer often evacuates several previously processed colors. This is due to the limited cleaning performance of virgin polymers.
