BOSTON (AP) — Gov. Deval Patrick is pushing a plan to ban commercial food waste, instead requiring that any leftovers be used for renewable energy instead.

Environmental officials say the ban would take effect next July and would force any company that disposes of at least one ton of organic waste per week to donate or reuse any useable food.

Under the plan, any remaining food waste would be shipped either to an animal-feed operation or an anaerobic digestion facility that can convert the waste into renewable energy.

Environmental Affairs Secretary Rick Sullivan said the plan is part of the administration's ongoing efforts to support the state's clean energy sector while reducing greenhouse emissions.

The ban would not apply to residential food waste.

The administration is making $3 million in low-interest loans available to companies building anaerobic digestion facilities.
