Late 80’s

The dawn of automationSimple semi manual fermentorsValidation becoming more involvedContainment being actively pursuedCIP/SIP systems becoming more complicatedAutomation seen as reducing

Headcount, Turn-round timeOperator errors

Early 90’s

Some companies begin to realise complex automation systems have drawbacks.

They see increasing HeadcountComplexity of plantTurn-round timesComplexity of investigations (variables)Facility build costsFacility construction times

Late 90’s to 2006

Some companies start to reduce cost by simplifying.

Stainless steel reactors are simplified by reducing numbers of valves/items.

Disposables reduce the need for CIP/SIP.

The fastest CIP?

Reduce the number of inlets that need cleaning.

Elan’s plant design breaks new ground (2008).

Large scale disposables are widely accepted

2000L reactors are launched onto the market (2010)

The Facility – the next generation of plant after élan

How do you make media next to the bioreactor without contaminating the

room with powder?

23

Contained media mixing – GEA

24

Contained media mixing – Hyclone

Hyclone Powdertainer

25

Contained media mixing - Lormac

26

Use of Buffer towers in Downstream worked example

27

The Facility – the next generation of plant after élan

How do you make and store up to 6,000L of buffer and not use large numbers of

buffer bags?

28

AnswerBy positioning 2,000L buffer towers close to the column and

‘topping up’ from 1,000L single use mixers.

Industry trends and expectations

Reduced production costs

Decreased capital investments

More flexible plants with faster turnaround time

Risk management and mitigation

Increased control over products, processes, timelines

Close cooperation, partnership, strategic alliances

Culture with a continuous improvements mindset
