Key takeaways
  • Launched in late 2018, X-Food aims to shed light on controversies on topics related to agriculture and food. In 2022, they published a report outlining 12 solutions to help reduce food waste.
  • Over 50% of French people do not know the difference between the “Use By” date and the “Expiration Date” – it is responsible for around 20% of consumer food waste.
  • Sizing and appearance criteria resulting from regulations, as well as certain buyers’ specifications, lead to a significant rejection of downgraded production.
  • It would also be possible, by changing the legislation, to offer products which do not meet aesthetic criteria more systematically to consumers at a reduced price.
  • At the national level, more visibility on the subject of food waste is needed.

Of dif­ferent regu­la­to­ry mecha­nisms, what issues are there around use-by dates ? 

This is an impor­tant issue, because more than 50% of French people do not know the dif­fe­rence bet­ween the “Use By” date and the “Expi­ra­tion Date”. The lat­ter, which is man­da­to­ry for rapid­ly per­ishable food­stuffs, is the date after which the pro­duct becomes unfit for consump­tion, as it may present a risk to human health. The for­mer is the date after which the pro­duct loses some of its nutri­tio­nal or orga­no­lep­tic qua­li­ties, but does not consti­tute a health risk. It is indi­ca­ted by the words : “Best before XX/XX/XXXX”.  

It is esti­ma­ted that this lack of awa­re­ness is res­pon­sible for around 20% of food waste at the consu­mer level. Moreo­ver, this issue goes beyond the natio­nal fra­me­work and is posed at the Euro­pean level, requi­ring changes to the regu­la­tions gover­ning consu­mer information. 

Seve­ral regu­la­to­ry changes could reduce the waste lin­ked to the misin­ter­pre­ta­tion of these dates. For example, the sta­te­ment “Use by” could be rewor­ded to read “Best before”. Poli­cy action could also be consi­de­red to replace some use-by dates with best-before dates and to expand the list of pro­ducts exempt from use-by dates. For example, cur­rent­ly salt or vine­gar are exempt, but not pas­ta or rice.

What is X‑Food ?

“Laun­ched in late 2018 under the impe­tus of École Poly­tech­nique alum­ni, X‑Food aims to shed light on contro­ver­sies on topics rela­ted to agri­cul­ture and food, and to pro­mote inno­va­tion. The tran­si­tion to heal­thy and sus­tai­nable food, in a context of world popu­la­tion growth, is a cru­cial chal­lenge. We have a dual approach, scien­ti­fic and holis­tic. On each sub­ject we stu­dy, we involve experts from all walks of life : resear­chers, indus­tria­lists, engi­neers, from the pri­vate and public sec­tors, and associations. 

We have orga­ni­sed four dis­cus­sion mee­tings over the course of 2020, moving pro­gres­si­ve­ly up the value chain : consump­tion and cate­ring, dis­tri­bu­tion, pro­ces­sing, and then pro­duc­tion, and each time cal­ling on 3 or 4 experts from the sec­tor. These mee­tings were fol­lo­wed by a sum­ma­ry confe­rence, the publi­ca­tion of a loss cal­cu­la­tion tool for pro­fes­sio­nals and a fif­ty-page sum­ma­ry docu­ment in which we pro­pose to act on 12 levers for control­ling food losses.

Other poli­cies are more dif­fi­cult to put in place, as they are at the inter­face of dif­ferent links in the food chain ? 

Yes, this is the case with fruit and vege­table waste, for example. Pro­du­cers can­not always sell their entire pro­duc­tion, due to cli­ma­tic hazards, mar­ket dyna­mics, or sani­ta­ry and regu­la­to­ry constraints. The sizing cri­te­ria resul­ting from regu­la­tions, as well as cer­tain buyers’ spe­ci­fi­ca­tions, lead to a signi­fi­cant rejec­tion of down­gra­ded pro­duc­tion. While health cri­te­ria are unde­niable, qua­li­ty cri­te­ria (sugar content, pro­tein content, etc.) or aes­the­tic cri­te­ria (colour, size, shape, etc.) seem more ques­tio­nable. They gene­rate signi­fi­cant rejects of so-cal­led “ugly” fruit and vege­tables. Euro­pean regu­la­tions impose such size and appea­rance cri­te­ria on ten pro­duct cate­go­ries that represent about 75% of the mar­ket ! This excludes down­gra­ded fruit and vege­tables from tra­di­tio­nal dis­tri­bu­tion channels…

This is a good example of the com­plexi­ty of the fight against waste. We could make use of this spoi­led food by pro­du­cing can­ned food. But this pro­duc­tion chain would then have to be sup­plied regu­lar­ly, which is contra­dic­to­ry when we are tal­king about spoi­led fruit and vege­tables. It would also be pos­sible, by chan­ging the legis­la­tion, to offer them more sys­te­ma­ti­cal­ly to consu­mers at a redu­ced price.

It is not enough to allow the sale of imper­fect pro­ducts ; consu­mers must also want to buy them ? 

As we can see here, again, the fight against waste involves seve­ral players. In this case, pro­du­cers conti­nue to pro­duce qua­li­ty-assu­red food because the consu­mer demands it. We the­re­fore need to encou­rage people at the end of the chain to buy these pro­ducts through pro­mo­tio­nal cam­pai­gns, such as the one that was car­ried out on “bro­ken heads” or “ugly vegetables”.

This is all the more true since the “anti-gas­pi” shelves or bas­kets contai­ning pro­ducts “close to the use-by date” suf­fer from a lack of expo­sure when they are not sim­ply dis­car­ded, as they are often pla­ced in bulk at the back of the shop. Chea­per food is also asso­cia­ted with lower food qua­li­ty. Com­pa­nies such as Zéro Gâchis or Smart­way, for example, pro­pose to trans­form the image of these shelves to make them attrac­tive, in par­ti­cu­lar by playing on the posi­tive image of the fight against waste. It is also neces­sa­ry to raise awa­re­ness among super­mar­kets of the posi­tive eco­no­mic impact of these departments.

The 12 solu­tions to food waste and losses as cited in the report

1. Ali­gn the defi­ni­tion of food waste bet­ween France & other organisations.

2. Cla­ri­fy the dis­tinc­tion bet­ween Use By and Expi­ra­tion dates, and remove some.

3. Mobi­lise Ter­ri­to­rial Food Plans (TAP) and public funding.

4. Reba­lance trade rela­tions in favour of farmers.

5. Take ano­ther look at cali­bra­tion and com­mer­cial specifications.

6. Make date contracts bet­ween sup­pliers and dis­tri­bu­tors more flexible.

7. Faci­li­tate the repro­ces­sing of agri­cul­tu­ral surpluses.

8. Iden­ti­fy and moni­tor pro­ducts that are close to expiry.

9. Deve­lop the sale of near-expi­ry products.

10. Streng­then and improve the qua­li­ty of unsold food donations.

11. Raise awa­re­ness among pro­fes­sio­nals and consumers.

12. Imple­ment food waste education.

One of the last (but not least) levers is infor­ma­tion and education ? 

A major source of loss and waste is to be found at the distribution/consumption inter­face ; it is the hyper-choice offe­red to a “hyper-consu­mer” who has to find his way bet­ween pro­ducts with a low car­bon impact, orga­nic pro­ducts, pro­mo­tions on chea­per pro­ducts, etc. 

At the natio­nal level, we need to increase the visi­bi­li­ty of the sub­ject, and make it a major natio­nal cause, as Guillaume Garot pro­po­sed during one of our debates. We should also set up, why not in schools, an edu­ca­tion on food waste. The youn­gest are gene­ral­ly sen­si­tive to these sub­jects, and they can bring about a change in attitude. 

What will be the next theme of X‑Food ? 

The issue of food loss and waste was our first topic. In 2021–2022, we have cho­sen the theme of ani­mal pro­teins : what are the dif­ferent impacts ? Should we real­ly consume less of it ? A sub­ject just as com­plex and contro­ver­sial as food waste !
