Output stability improves significantly when streams are kept consistent.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is PVC contamination such a big problem?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">PVC mixed into PP\/PE streams is a common cause of quality issues and processing instability. If your feedstock may contain PVC, prioritize pre-sorting and consider dedicated processing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do I need a washing line for rigid plastics?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your rigid plastics are post-consumer or contaminated (labels, glue, oil, dirt), a washing line is typically required to achieve clean flakes or stable pellets. For clean factory scrap, washing may be minimal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What equipment do I need for rigid plastics recycling?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Most rigid plastic workflows use size reduction first (shredder and\/or granulator), then washing\/drying as needed. For pellet production, add a pelletizing line. See: <a href=\"https:\/\/www.recyclemachine.net\/complete-recycling-solutions\/\">Complete Recycling Solution<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should I produce flakes or pellets?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Flakes typically require lower investment and are often used for in-house reuse. Pellets can be higher value but require stable cleanliness, moisture control, and melt filtration.
