I want to move beyond “swap to kraft” and into measurable impact — balancing shelf presence with end-of-life clarity — so I’m hunting for legit training that sticks. Has anyone taken SPC’s Essentials of Sustainable Packaging or Trayak’s COMPASS with Esko and found it directly improved your dielines and spec calls? I tried OpenLCA on a molded fiber vs. corrugated insert last month and got lost in datasets, so a structured path would help.
And do TU Delft’s edX LCA, then COMPASS; cross-check specs with APR Design Guide Design Guide Welcome Page - Association of Plastic Recyclers (APR). Which database?
Agree with @sarah_lee93, but the shift in my dielines came when I calibrated COMPASS with two supplier EPDs and our real trim waste; SPC Essentials gave me the language, COMPASS gave me the levers. Since you ran OpenLCA on molded fiber vs corrugate last month, re-run with palletization and a 2–3% damage rate — COMPASS defaults can over-credit fiber, and corrugate can win once transport is in. Quick step: build a massed BOM (incl. ink g/m², glue dots, tape) and see if a 2 mm panel trim saves 5% sheet area without killing shelf presence.
