Abstract

Recycling the organic waste is considered as a great problem allover the world and especially in the Arab countries which have an increase rate of population and development. Most of these organic wastes are dumped in landfills and a very few are buried in specially designed underground places. The decomposing of such organic wastes leads to the production of greenhouse gases as CO2 and methane. Also, it causes many problems to the underground water. The current project aims to the building a sustainable composting unit for the disposal of the organic wastes using the earthworm which will feed on them. After digesting the worms for these organic wastes, it produced a cast called vermicompost which is very rich in organic nutrients as well as growth hormones which will be very useful for plant growth. Moreover, the production rate of these worms is very high and also its protein content reach 70%. So, the dried worm meal can be used as a supplementary feed for fish and poultry. This in turn will decrease the fish and poultry production coast and hence decrease the overall prices of such important human food. So the current project is trying to solve the problem of organic wastes in cities and also converting them to a valuable and important product. Moreover, such techniques will decrease the overall emission of greenhouse gases.
