Food waste: a sustainable animal feed Erasmus zu Ermgassen, MRCVS Conservation Science Group University of Cambridge @erasmuszu

75% of the environmental impact of EU pork is from feed production Sources: Nguyen et al. (2012) J Clean Prod; Herrero et al. (2015) Ann Rev Envir & Res
3
Novel, low-impact animal feed
4
A history of food waste as feed:
7
No food waste that has been through a kitchen. No meat for livestock EC regulation 1774/2002 1 2
8
In Japan and South Korea 40 % of food waste is fed to livestock

The potential for swill-feeding in the EU… (a)The EU pig industry (b)Effect of food waste on land use? (c)What food wastes are available for animal feed? (d)Putting it all together. What would happen if we re-legalised swill in the EU?

The potential for swill-feeding in the EU… Impact on feed & land use: (a)The feed & land use of EU pork (b)Effect of food waste on land use? (c)What food wastes are available for animal feed?
15
Food waste would replace enough grain to feed 70m Europeans

Source: zu Ermgassen et al. (2016) Food Policy Food waste feed would reduce the land use of EU pork by 20%

24
Barriers to food waste feeding Producers Disease Meat quality Price What’s safer? (i)Current ban – 24% of smallholders break the law (ii)Regulated systems for safe food waste processing Source: Gillespie et al. (2015) Vet Rec
25
Barriers to food waste feeding Producers Disease Meat quality Price Indistinguishable from conventional pork No effect on 16/18 measures of meat quality Source: zu Ermgassen et al. (2016) Food Policy

Barriers to food waste feeding Producers Disease Meat quality Price Lower cost Higher profits

- Wadhwha & Bakhsi (2013) Food waste as ruminant feed
28
“Noodle waste can be utilized as a substitute for barley-and-corn concentrate for beef fattening” – Ishida et al. (2012) J Anim Sci
29
“Replacing 40% of commercial concentrate with potato waste, noodle waste and soybean curd residue can make a suitable TMR” – Yani et al. (2015) J Anim Sci

Potential to increase use in both monogastrics and ruminants Economic and environmental benefits Best practice in East Asia Requires re-legalisation in parts of the world Food waste: a sustainable animal feed
