Monday will be the final day Lawrence residents can separate yard trimmings from normal waste collection.

Kathy Richardson, the city’s supervisor for waste reduction and recycling operations, said this year’s curbside collection has diverted more than 11,900 tons of grass and leaves from being put in the landfill this year.

The materials are converted into compost for use by residents and city landscaping. In case of inclement weather Monday, collection will resume Dec. 29.

The yard waste collection will resume regularly March 2. During the interim, yard waste will be picked up with regular household trash collection.

Also, after Christmas, live-cut trees can be placed at the curb or alley for collection by 6 a.m. on Jan 5 and Jan 12. The trees will be used for a wildlife habitat. All artificial items, including tinsel, lights and tree stands, must be removed.
