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.

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.

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
