Abstract: The using of organic fertilizers is essential, which do not pollute the environment and also contribute for a more delicious and healthier food and sustainable yields in a distant period of time. On the planet billions of tons of organic waste are created every year which contain all the necessary elements and compounds: proteins, vitamins, salts, active biological substances etc. By applying new techniques in the composting we have achieved to obtain a quality product in its entire volume, and to preserve as well the activity of the red Californian worm /RCW/ for a maximum long period of time. By applying a specific proportion in the mixture of sediments from wastewater treatment plants and straw, and by adding technologically activated mineral rocks, we have achieved to obtain a compost having the specific organoleptic characteristics and to reduce in full the unpleasant smells.
