Composting Toolkit

Food waste accounts for 24% of municipal solid waste (EPA, 2018). Food scrap composting has become easier in NH with changes to municipal and commercial composting regulations. 

Food scrap composting saves economic and environmental resources, as food waste is diverted and does not end up in a landfill or incinerator. 

In this Composting Toolkit, you will find the basics for municipal food scrap composting in a video and a printable resource, several resource links for operators, helpful articles to share with residents, and case studies.

(Video should load shortly or watch the Municipal Food Scrap Composting Toolkit Video on YouTube)

Key Takeaway: a municipal compost program can be a cost-effective way to divert food scraps and decrease municipal solid waste.

WHAT TO DO

There are several type of food scrap diversion options a municipality can utilize, including:

• On-site composting where a transfer station receives AND processes food scraps into compost on transfer station grounds.
• Off-site composting where a transfer station collects food scraps on-site and then transfers them to another facility to be processed into compost.
• Off-site composting with a non-solid waste facility community collection center.
• Curbside collection by contracted food scrap haulers to be processed either on or off site at the transfer station.
