Environmental Aspects

Industries are keen to reduce their environmental footprint. It is interesting that, frequently, following a “Green” footpath often leads to additional benefits including reduced waste and reduced, associated costs.

Flow Chemistry has a smaller impact upon our environment in several areas.


  • Energy requirements are lower than for a similar batch process.
  • Temperature control takes place faster, requiring less energy.
  • Reactions tend to require less time, further reducing energy requirements.


  • Volumes tend to be less than for batch.
  • Product tends to be of higher purity and yield, leading to reduced purification requirements.
  • System cleaning can be done in-situ requiring less effort and solvent.
  • Photochemistry, particularly suited to flow conditions, consumes less solvent and produces less waste.
  • The use of microfluidics further reduces development time with associated reductions in waste and cost.


  • Flow systems tend to be physically smaller than comparable batch systems.
  • Reduced investment costs for the equipment and space requirements for the equipment and chemical storage.
  • Flow system designs frequently utilise “off-the shelf” components. These can be reused in new designs.
