The city’s curbside yard waste collection program is set to resume operations Monday.

That means city residents need to stop using plastic bags for their leaves, grass clippings and other yard waste. It also means all yard waste should be set out for pickup on Mondays and shouldn’t be included with regular trash.

The city has run the curbside yard waste collection program from early March through mid-December since 1993. But last year the city approved an ordinance that requires residents no longer use plastic bags. Instead residents should use paper bags that can be composted, cans or carts.

The city banned the use of plastic bags for yard waste because city crews had to spend time emptying the compost out of the bags, which made the process less efficient and increased the chances of plastic becoming mixed in with the compost produced from the yard waste. Crews won’t pick up yard waste left in plastic bags.

Plastic bags are still allowed for normal trash.
