The Afterlife of Christmas Trees
Ever wonder what happens to Christmas trees collected off sidewalks? (Aside from the occasion topiary farm project, that is.) Somerville and Cambridge mulch the trees. Somerville residents can pick up mulch from the Department of Public Works. Cambridge recycled more than 4700 trees last year for mulch, which was used in city landscape projects and parks. Medford trees are composted. And some municipalities--not any locally--are starting to use the mulched trees for biomass-fueled power plants.
