Bill Summary · HB 477

Legislative bill overview

HB 477 would phase out polystyrene (styrofoam) single-use food containers in Montana, with certain exceptions for specific products or circumstances. The bill passed both chambers of the legislature but was vetoed by the Governor on May 1, 2025, preventing it from becoming law.

Why is this important

Polystyrene containers take centuries to decompose and are a significant source of environmental pollution and litter. This type of legislation reflects growing state-level efforts to reduce plastic waste, though it ultimately failed at the executive level in this case.

Potential points of contention

  • Economic impact on businesses: Food service providers would need to transition to alternative containers, potentially increasing costs for restaurants, takeout establishments, and food vendors
  • Scope of exceptions: The bill's carve-outs could be viewed as either insufficient protections for affected industries or as loopholes that undermine environmental goals
  • Enforcement and compliance: Questions about how the state would monitor compliance and what penalties would apply to violators
