Manhole covers are the readily visible parts of a manhole—there are even historical approaches to the art of decorating manhole covers. But down beneath the surface is the unseen yet vital framework of the manhole itself. Modern manholes are generally constructed of precast concrete, plastic, or fiberglass.
Garden refuse primarily refers to organic materials produced during gardening activities. It can be broadly categorized into green waste, which includes grass clippings, plant trimmings, and soft green leaves, and brown waste, such as dry leaves, branches, and twigs. These materials, when disposed of improperly, can contribute to landfill overflow and increase greenhouse gas emissions. In light of these environmental concerns, finding a sustainable approach to garden refuse disposal is crucial.
