Summary:[Display omitted] •Raw lignin was modified through a green and scalable reactive extrusion design.•Lignin/poly(butylene adipate-co-terephthalate) biomaterials were melt processed up to 90 wt% bio-content.•Tough biomaterials were film blown and shopping bags were produced.•Mechanical recycling and composting were verified as end-of-life options.•Reactive design was industrially scaled-up in conventional twin screw extruder.
