Most home compost systems do not reach the\n                    temperature and stability needed for reliable PLA breakdown, so recycling or controlled disposal is\n                    often more realistic.\n                <\/p>\n            <\/details>\n\n            <details>\n                <summary>Can I mix different filament types when recycling?<\/summary>\n                <p>\n                    No. Mixing different polymers can cause contamination, inconsistent extrusion, weak prints, and\n                    unreliable mechanical properties.
