Excellent question! So in the vast majority of locations, recycling facilities require items set out curbside to be loose in the bin. However, there are some locations that have curbside pick up service without bins, or allow large recycling bags when residents have overflow from their bin. It is best to check what your specific location allows in this respect. Otherwise, it is not good to put your recyclables into small bags then throw them into your bin- so if you’re using little grocery bags to collect them inside your home, please dump them into the bin un-bagged.
