wasted before and after it reaches the
consumer” (Lundqvist et al. 2008)

Impacts of food waste
• Social– Over – Population VS. Food security
• i.e: not enough food for all!
• Economic– Wasted Food = Waste of Money!
• Environmental– Greenhouse gases (CH4, CO2)
– Limited natural resources (water, nutrients, energy etc.)
– Pollution (air, rivers, groundwater, soil)
Embedded GHG emissions of food waste from
previous lifecycle stages

Options for food surplus and
food waste management
Prevention
• Avoid surplus food generation throughout food production and consumption
Re-use
• Use surplus food for human consumption through redistribution networks & food banks
Recycle
• Use of food waste as animal feed
• Composting
Recovery• Treat food waste and recover energy e.g. anaerobic digestion
Disposal• Sanitary landfill with landfill gas utilisation technology
