Madison Square Garden and other major New York City sporting venues would have to recycle all food waste under new rules unveiled Thursday to expand the city’s composting program.

The rules would also cover restaurants at hotels with at least 150 bedrooms and large food manufacturers and wholesalers, and are part of Mayor de Blasio’s goal of having zero food waste going into landfills by 2030.

Fines for noncompliance would range from $250 to $1,000 for repeat offenders. Some 350 affected businesses would have to comply within a year of the rules being formalized after a public hearing in October.
