 Increasing concern over environmental degradation and the danger of non-sustainable development as well as the need for alternative (“green”) energy from renewable resources has enhanced the role of environmental management of ecosystems. The cow dung must be removed from the cow barn every day, at considerable expense, and dumped, to the detriment of the environment. The use of Biogas technology of solid and liquid manure from the cow barn was demonstrated as a means of reducing environmental hazards.
Today, anaerobic digestion is widely accepted as a sound technology for many waste treatment applications, and novel reactor designs are being applied on a commercial scale. In spite of this acceptance, advances are still being made, and developments in this department are concentrating on the uses of the digested slurry.
New and already developed approaches and processes for upgrading the quality and use of the effluent from anaerobic digestion are the reason for more economical uses of bioenergy processes.
Biogas production combines the short-term economic needs of our communities with conservation and the end of ecological degradation. Its benefits are:- Reduces odor problems.
- Protects water resources.
- Controls pathogens.
- Reduces methane emissions - a potent greenhouse gas.
The group is involved in several aspects of implementation in cow barns. On the basis of the know-how 3 full scale plants were built several years ago in Israel and 3 outside Israel. |
