Bio gas is the answer for three major problems: environment management, energy management and agri system management, President of the Lanka Biogas Assosiation, Professor Ajith de Alwis, said at the launch of Biogas Association yesterday. Sri Lanka must try to promote bio gas as a technology. Though in the past bio gas was considered a poor man's technology, it is well accepted and recognized for its triple importance and the unique capabilities of the process. Citing examples, he said that bio gas is used efficiently at the Karapitiya Hospital in Galle, to cut down the use of LPG. He believes that other hospitals in the island would learn from that experience. Chief Guest, Science and Technology Minister Professor Tissa Vitarana after launching the Lanka Biogas Association's Web Page, said he considered it a start of new era. He said the world is becoming a difficult place to live in for humans and all life forms. He believes indigenous knowledge and science will be the solution for many problems. Twenty per cent of the energy needs can be met by bio gas. Vitarana also said that Cabinet had appointed a scientific community for renewable energy and the National Engineering and Research Centre (NERD) is already is involved in finding solutions. Bio Energy Association of Sri Lanka, President Parakrama Jayasinghe said Sri Lanka needs innovative approaches even if oil is found in Mannar. He said that it's a moral obligation not to use it for our purposes alone but to preserve it for the future generations. Sri Lanka has huge amounts of renewable energy that could be used even 100 per cent as an energy resource. "After all bio mass is our wealth, but we are not using it. Definitely we have the science but look into the technology. We must make sure that technology is there. Practical Action which facilitated the launch has been in the forefront of advocating the energy needs of disadvantaged and rural communities and has collaborated in a number of research and development organizations. With the inputs of Practical Action 700 bio gas units have been constructed all over the island.
