Requires solid waste management districts to develop strategy to reduce food waste; requires DEP to adopt certain rules and regulations regarding composting facilities.

S 663 requires New Jersey's solid waste management districts (including counties and the Hackensack Meadowlands District) to create a plan reducing food waste by 50% by 2035 compared to 2022 levels. Districts must add this plan to their solid waste management strategy for approval by the Department of Environmental Protection (DEP). The DEP must also publish practical methods for achieving this goal, such as increasing food donations and composting, and establish a tiered regulatory system for composting facilities to support organic waste recycling.
