Since Vermont's battery product stewardship law went into effect in January 2016, requiring battery stewards to pay for the collection and recycling of their products, Chittenden Solid Waste District recycled almost 18,000 lbs. of used batteries, "well above its battery shipments for any recent year. Single-use batteries make up more than half of the 2016 battery shipments – in distinct contrast to the period between 1999 and 2015, when rechargeable batteries comprised 80% of all shipments." Call2Recycle expects this "upward trend in battery recycling to continue as more Vermont residents find out about the single-use battery program. The volume of single-use batteries being dropped off for recycling should greatly exceed that of rechargeable batteries from now on." 96% of Vermont residents have a Call2Recycle collection site within 10 miles of their homes.
