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.
