Hierarchy to Reduce Food Waste and Grow Community

Download to read offline

We’ve developed this Hierarchy to Reduce Waste & Grow Community in order to highlight the importance of locally based composting solutions as a first priority over large-scale regional solutions. Composting can be small scale and large scale and everything in between but too often home composting, onsite composting, community scale composting, and on-farm composting are overlooked. Anaerobic digestion systems come in different sizes as well. This new hierarchy addresses issues of scale and community benefits when considering what strategies and infrastructure to pursue for food waste reduction and recovery.

Hierarchy to Reduce Food Waste and Grow Community

  1. 1. Hierarchy to Reduce Food Waste and Grow Community
  2. 2. Prevention. Do not generate food waste in the first place! Reduce portions, buy what you need, and organize your fridge for optimal food usage.
  3. 3. Feed hungry people. Divert food not suitable for people to animals such as backyard chickens or to local farmers’ livestock.
  4. 4. Composting in backyards or in homes. Avoid collection costs!
  5. 5. Onsite composting or anaerobic digestion, and community composters can accept material from off-site or simply process their own material.
  6. 6. Composting or anaerobic digestion at the small town or farm scale. These systems handle typically between 10 and 100 tons per week and are designed to serve small geographic areas.
  7. 7. Facilities serving large geographic areas that typically handle more than 100 tons per week. Material generally leaves the community in which it is generated.
  8. 8. Mixed garbage is mechanically and biologically processed to recover recyclables and reduce waste volume and the potential for methane emissions before landfill disposal.
  9. 9. Food waste should be banned from landfills and trash incinerators due to their high capital costs, pollution, and contribution to greenhouse gas emissions.
