01 Feedstock
Ore, monomer, fibre, mineral or scrap that can legally become Placa de gesso.
Placa de gesso · Painéis de gesso di-hidratado que compram tempo de fogo ao calcinar.
Making Placa de gesso is a chain: feedstock, conversion (Sackett 1894; US Gypsum 1916), forming, heat, finish, install.

Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
Coatings, sizings, facers, galvanizing, anodising, painting.
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
Virgin route around United States.
Placa de gesso has a real loop when sorting is honest.
High-spec grades leave the commodity mill.
Coatings, sprays, casts — the factory is sometimes a jobsite.
Feedstock to installed product.
Energy in, class out.
Melting/softening calcines ~80–180 °C (dehydration); conductivity ~0.17 W/m·K.
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Placa de gesso.
Fire class A2-s1,d0 typical; core A1 is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
