Potential to save up to 70% of process water BUT this comes at a carbon cost

CARBON COST? EXTRA

Use of green
electricity could offset this carbon
cost
A very delicate balancing act in order to preserve our planet’s resources
SWAN Project – 3 years ago looked unlikely, but now plants being installed
Why now? Inability to discharge to local sewerLack of water supply
Where? S Africa; Australia; China; Holland; UK
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 quality.
CARBON MANAGEMENT - THE SAFEST BET
How can Muntons help farmers save money and reduce the supply chain carbon footprint?
Muntons WIN!
Sustainable Manufacturer of the Year 2011

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

Relative incomes makes barley hard to get grown
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
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

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
