Create clean elegant lines that highlight sweeping landscape design curves. Made from 100% recycled milk jugs and other high density polyethylene post consumer plastics. Master Mark Plastics has become a premier name in lawn, garden, and building supplies throughout the world due to the fact that we are one of the largest and most experienced recyclers of HDPE plastics. High Density Polyethylene plastics, which include hefty weight materials like milk jugs and detergent containers bottles that do not easily disintegrate. Therefore, this garbage would last many years in a landfill. Our recycling operation takes this plastic, grinds it up, sterilizes it, and treats it for further use in our lawn and garden products and composite decking materials.
