Abstract Greenhouses are one of the important agricultural technologies in crop production under the rise of the world population and the extreme climatic changes. It is important to maintain an environment that promotes optimum plant growth and production all year round. The growth factors are light, temperature, humidity and air composition should be delivered and maintained at optimal levels. To maintain this optimum growing environment, greenhouses ought to allow high light transmittance, heat consumption, sufficient ventilation efficiency, low construction and operating costs. Agricultural waste in Egypt is a great importance as it causes pollution to the environment. For that in this study through the use of ideal for the disposal of these wastes in addition to the production of new energy (biogas) and a environmentally friendly. Biogas production is of major importance for the sustainable use of agrarian biomass as renewable energy source. Economic biogas production depends on high biogas yields. |
