2. SWAN Project – 3 years ago looked
unlikely, but now plants being installed
Commercial Trial Was
Successful!
Membrane Bioreactor
linked to Reverse
Osmosis is an
acceptable technology
for producing recycled
water for malting.
Malts made with
recycled water
produced malts and
beers of the highest
Why now? quality.
Inability to discharge to local sewer
Lack of water supply
Where?
S Africa; Australia; China; Holland; UK

3. CARBON MANAGEMENT - THE SAFEST BET

4. How can
Muntons help
farmers save
money and
reduce the
supply chain
carbon
footprint?

5. Muntons WIN!

of the Year 2011

6. Carbon Footprint Calculation: Barley to Brewery/Distillery
(Scope 1 and 2) – Different methodologies agree well
Fuel 17%
N2O from
Soil 35%
N fertiliser
48% Overall

different

7. Low Carbon Malt Commitment
We are committed to producing 100% low carbon malt
using low carbon options to make a significant impact
on our supply chain carbon footprint.
WE HAVE CALCULATED OUR CARBON FOOTPRINT

8. Why grow Malting Barley?
MARKET
RISK Niche
Higher risk in market, locally
hitting spec and influenced
quality

10. Compost, Biosludge, Sewage Sludge - aren’t
they all the same? NO!!
Sewage Sludge if
untreated is clearly a
risky product
If treated properly there
is no reason to believe it
is not safe to use IF
CERTIFIED
BUT… we are treading
carefully and using the
least controversial
alternate fertiliser

11. Compost is not a waste if PAS100
Compost is analysed for the following:
Pathogens: E. Coli, Salmonella
Physical contamination: Glass, Stone, Plastic
Weed seeds
Metals: Cd, Cr, Cu, Pb, Hg, Ni, Zn
Muntons specify PAS100 +
We cannot accept composted material that
has been derived from onions, leeks or
garlic, or anything else that generates a
strong taint

13. Muntons Farming Carbon Footprint Calculator
We used PAS 2050 to establish some ground rules
Originally used the MAGB carbon footprint model
Now enhanced that using the ECOINVENT database and LCA
Selected the top 10 influencers on farm
Purpose to demonstrate which actions are worthwhile and
to get farmers involved in a practical debate
