SUMMARY:Who wants my half eaten sandwich? Food waste in the digital sharing
  economy
DESCRIPTION:Reducing food waste is widely recognized as critical for improv
 ing resource efficiency and meeting the nutritional demand of a growing hu
 man population. Here we explore whether the sharing economy can provide me
 aningful assistance to reducing food waste in a relatively low-impact and 
 environmentally-sound way. Analyzing 170\,000 postings on a popular peer-t
 o-peer food-sharing app\, we find that over 19 months\, 90t of food waste 
 with an equivalent retail value of £0.7 million were collected by seconda
 ry consumers and diverted from disposal. An environmental analysis focused
  on Greater London reveals that these exchanges were responsible for avoid
 ing emission of 87-156t of CO2-eq. These findings\, together with the high
  collection rates (60% on average) suggest that the sharing economy may of
 fer powerful means for improving resource efficiency and reducing food was
 te. However\, since most exchanges were among users associated with lower 
 income yet higher levels of education\, cultural capital might be a prereq
 uisite for successful participation in free P2P sharing economy networks\,
  putting into question the degree to which the food insecure actually part
 icipate or benefit from such exchanges.
