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.

Our preocess

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.

Our innovative industrial biotechnology enables today’s manufacturers find ways to create products that offer better performance, quality and sustainability across a wide range of end uses.
