5XPopulation estimates projected in 2040

70% of the water entering a brewery leaves it as effluent, 3 – 10 hl water is needed to produce 1 hl of beer

Brewery processes are intensive users of both electrical and thermal energy - 3 to 8 % of production costs of beer is energy & water

By appropriate waste managementbreweries can save 4.5% on theiroperational costs. The tendencyof this percentage is up.

Brewing Industry and Sustainability


HOW DOES BEER MEMBRANE FILTRATION SUPPORT?

For more than a decade

sustainability is high on

the agenda of the brewer

CO2 Footprint (1)


An investigation was executed to come to grounded number for CO2 footprint for

membrane filtration and DE filtration of beer

For the calculation of CO2 footprint the following directive of the British Standards

Organization BSI was used – ‘Guide to PAS2050: How to asses the carbon foot print

of goods and services

The CO2 footprint is calculated over the whole supply chain, so also energy

consumption in the production and shipping of DE and membranes is taken into

account

The energy consumption in making membranes has been taken from the Pentair

factory in Enschede

Water Consumption


DE Filtration

Water in a DE filter is used for flushing

out the DE, cleaning and sterilization

Consumption depends on run volumes

Typical consumption is 0.1 – 0.2 hl/hl

Membrane Filtration

Water in a BMF is used for periodical

back flushing with cold caustic and

regeneration of the membranes

Consumption depends on achieved run

volumes

Typical consumption is 0.1 - 0.2 hl/hl,

lower for beers produced with adjuncts

and use of extra enzymes

15

Solid Waste Stream


Typical solid waste stream of a brewery is 0.8 kg/HL

DE is responsible for 50% being 0.4 kg/HL

For a brewery with an annual output of 1,000,000 HL it means the following:

• DE Filter: 400,000 kg/yr

• BMF: 180 kg/yr (replacement of membranes)

16

Beer Loss (1)


With a Membrane Filter the beer is washed out and directly dosed back in the beer

stream – No Head & Tail Tank needed with complicated logistics because of dosing

back procedures and limitations in mixing

17

Beer Loss (2)


System Volume is lower vs. DE filter - 30 HL vs. 70 HL

Especially in high gravity processes and high run volumes, the membrane filter can

reach down to 0.1%

A DE filter can reach this number seldom, only in a brewery with very low SKUs and

brand changes

As an average the beer loss for DE filtration is double the beer loss of membrane

filtration

Lower CO2 footprint – 40% reduction vs. DE

50% Lower Solid Waste Stream – Strong reduction

Water Footprint – Comparable level vs. DE

Average 0.2% Beer Loss – DE has double

Shelf Life - Better taste stability – No iron pick-up

Take Home Message


With the BMF the brewing industry

has an alternative for beer filtration

with a clearly better contribution to

a sustainable beer brewing &

production process

Especially the 50% reduction of

solid waste stream, lower beer loss

and better shelf life of a membrane

filter is supporting the brewery on

sustainability KPI’s
