Ekonomiczne i efektywne działania i skalability

Thee economic case for continuous procesing is comelling. Capital exclure (Capex) can be reduced by up to- 40- 60% compared to an equivalently productivy batth facility. This is due te reduced size of equipment, elimination of large holding tanks, and a smallar building footprint.
