You have an opportunity to recycle your Christmas tree, among other things. The Vanderburgh County Solid Waste District and the Wesselman Nature Society will conduct the annual Holiday Recycling Day on the back lot of the Civic Center from 8:00 AM until noon today. You can get your real tree grounded into mulch. If you want to keep the mulch, take along a container for it. Other materials will be recycled, including gift wrap, greeting cards, newspaper, household paper, magazines, catalogs, cans, glass containers, and No. 1-though-7 plastic containers.
