About

Environmental Biotechnology is defined as the development, use and regulation of biological systems for remediation of contaminated environments (land, air, water) and for environment-friendly process, green manufacturing technologies and sustainable development.  It manipulates microbial organisms while exploiting their beneficial properties to serve the human community. This has paved the way for efficient environmental conservation strategies against global warming and climate change. Environmental biotechnology can be used to detect, prevent and remediate the emission of pollutants into the environment in a number of ways. Some of the emerging environmental biotechnology trends in the world include a broad range of applications such as bioremediation, prevention, detection and monitoring, genetic engineering for sustainable development and better quality of living.

Ethiopia as Vavilonian gene center of crop diversity is endowed with an enormous biodiversity that can serve as a platform to establish a successful bio-economy. Above all, Ethiopia has an extremely unique microbial diversity, many of them found in extreme habits, not found anywhere else in the world.  Recognizing the potential of biotechnology for the country’s sustainable development, the Ethiopian government has established Ethiopian biotechnology institute in 2016 to carry out sustained cutting-edge research. The institute has twined the usual way of doing research and brought a new paradigm focusing on problem solving applied research. Under this institute, Environmental biotechnology directorate is the one which is responsible for environmental biotechnology researches. Some of the thematic areas of environmental biotechnology are bio-remediation, bio-energy, waste water treatment and solid waste management. Although the institute is young to generate technology, a lot of problem-solving researches were conducted, technologies were developed and transferred to the end users. In its attempt realize resource recovery and zero waste industries, the directorate ሃስ developed various value-added products from sugar industries wastes. Briquette technologies, partial cement replacement using boiler ash technology are among the technologies developed and transferred under this directorate. 

On the other hand, environmental biotechnology directorate has been working on biocontrol and biofertilzer technologies to replace polluting chemicals with environmentally friendly technologies. Of these, biocontrol technologies made of Beauveria bassianaMetarhizium anisopliae and Bacillus thuringiensis to control tomato leaf miner and Tuta absoluta were tested under field conditions and resulted in promising outputs. The integrated application of microbial, botanical and chemical pesticides for the control of whiteflies on tomato for the production of healthy seedlings are the two technologies developed by Addis Ababa University with support of EBTI and tested in the field and transferred to the community under our directorate. In addition, rhizobia and endo mycorrhizal inoculant development are under way in collaboration with INTA of Argentina and ASTU.

Environmental biotechnology directorate has produced particle board from coffee parchment which is major sources of environmental concerns in coffee producing areas. The technology is ready for transfer in this fiscal year following feasibility study. Furthermore, hybrid board and food grade gelatin are produced from chrome shaving and skins thrown away as waste in the environment. Microencapsulated biocontrol agent for commercial use in Ethiopia is also under development. Generally, a lot of research outputs are in the pipeline and when completed, will be tested at pilot level, checked for feasibility and if fulfill the requirements for transfer, it will be transferred to the users. 

Research Gap

In Ethiopia most industries are releasing their wastes directly to the environment without any treatment. Almost all cities and towns of our country lack environmentally sound and modern waste management systems. As a result, environmental pollution has been among a major public health concern. These all require prompt technology-based solutions which are both environmentally and economically feasible.   Our low in put agriculture has been using some polluting chemicals excessively and hence water bodies found in their immediate environment are severely polluted. Therefore, the quest for better technologies to ensure sustainable environmental management is very high than ever in our country. Our directorate is working to bridge these gaps by conducting problem solving research and coordinating research activities of the sector at national level.
