The plastic simply goes over the surface of the prepared vegetable bed, with the edges weighed down with soil or stones. Black plastic can be used on flat beds and raised beds, and in some areas of the with long growing seasons, two crops can be grown in the same bed. The plastic usually lasts two years before it begins to break down.

Abstract. The intent of the present research work is to explore the prospect of replacing natural soil used in brick making by some extent with industrial waste, that is, lime mud, as obtained from paper mill waste. Extensive adoption of this mill waste as a brick making material will deter the environmental effects of this waste disposal.
