Made from ultra-durable HDPE (high density polyethylene) partially derived from recycled single-use plastics like milk jugs and shampoo bottles, the Arbor Birdhouse is a durable, maintenance-free solution for avian living. Its solid maple front panel will grey out over time but requires no maintenance. Made by Arbor Wood Co., this wood is thermally modified using only heat and steam. The result is a performance-driven material that keeps the wood’s natural beauty without the use of harsh chemicals. All Loll outdoor furniture is made with recycled high-density polyethylene (HDPE). Colored material is post-consumer recycled HDPE sourced mainly from single-use milk jugs, while black material is post-industrial recycled HDPE. More than 95 percent of the waste from Loll's manufacturing process is sent to a local recycling plant where it is recycled again. From the HDPE plastic to the aluminum inserts and stainless steel fasteners, Loll furniture is all recyclable.
