CNC-milled HDPE or recycled composite molds cost $800\u2013$3,000 versus $15,000\u2013$40,000 for aluminum EPS steam dies, making short runs and design iteration economically viable. Per-part costs at 10,000+ volumes land at $0.35\u2013$1.20 depending on part thickness and grow-cycle utilization. Labor and grow-room throughput (5\u20137 day cycles) are the throughput bottleneck, not material cost \u2014 agricultural substrate runs $0.05\u2013$0.15 per liter.<\/p>\n<h2 style='color:#0f172a; margin-top:36px; margin-bottom:16px; font-size:1.5rem; border-bottom:1px solid #e2e8f0; padding-bottom:8px;'>Compliance and Lifecycle Claims<\/h2>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">Under the EU Packaging and Packaging Waste Regulation and expanding US state EPR schemes, mycelium packaging qualifies as home-compostable and typically carries no PCR content obligations (it is virgin bio-based by nature).
