Our Process – DuPont Tate & Lyle Bio Products
How it’s made
Most everyday consumer and industrial products are made using non-renewable resources, such as petrochemicals. But the overuse of these finite resources is not sustainable.
Bio-based 1,3-propanediol (PDO) is manufactured through a proprietary fermentation processing using plant-derived glucose instead of petroleum feedstocks.
The greener alternative
From “cradle-to-gate” (extraction and production prior to delivery to customers), bio-based 1,3-propanediol produces 47% less greenhouse gas emissions and consumes 49% less nonrenewable energy than petroleum-based 1,3-propanediol. Compared with propylene glycol (PG), bio-based 1,3-propanediol produces 42% less greenhouse gas emissions and uses 41% less nonrenewable energy from cradle to gate. Compared with butanediol (BDO), bio-based 1,3-propanediol produces 48% less greenhouse gas emissions and uses 46% less nonrenewable energy from cradle-to-gate.
*Footnote: DuPont engineers performed a Life Cycle Analysis on petroleum-derived PDO, PG, BDO, and bio-based PDO. The LCA was third-party peer reviewed by a panel of academia and industry experts: Professor Jay S. Golden, East Carolina University (lead), Professor Richard Venditti, North Carolina State University, Professor Roland Geyer, University of California Santa Barbara, Barruch Ben-Zekry, Director Sustainable Products & Materials, VF Corporation
