HB 477
Montana bill to phase out polystyrene food containers was vetoed by Governor despite legislative passage, blocking environmental waste reduction effort.
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.
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.
