How By-Products Of The Paper Industry Can Be A Resource For The Chemical Industry
INGEVITY IN THE NEWS
Published in the June 2022 Chemistry Can newsletter for the European Chemical Industry Council – Cefic
In the circular economy, the aim is to reduce the use of resources, re-use products as long as possible, and enable recycling at the end of their lives. One way of conserving resources, is by using the by-product of one industry to supply another.
Ingevity uses two by-products from the kraft paper industry – black liquor and chemical-grade crude tall oil (CTO) – to produce chemicals:
A lignin-based chemical with carbon negative properties
The lignin-based chemical made from black liquor is used mainly as a dispersant in the agriculture industry for a diverse set of crop protection formulations including biological products. The production process – including the energy use, materials, packaging and waste – releases 1.46 Metric Tons of carbon dioxide equivalent. A recent study shows this is 122% lower than fossil carbon-based alternatives when accounting for the biogenic carbon sequestered in the lignin, which results in a credit of -2.2 Metric Tons of carbon dioxide equivalent.
