3.8 Accomplishments

  1. Initiated researches on the aquatic macrophytes in the removal of heavy metals and its application to waste management.
  2. First time showed that normal tadpoles can remove Cyclopes, the invertebrate vector from pond waters which can be used as an intervention to control Dracunculiasis in tropical developing countries.
  3. Initiated source separation of household wastes in Nigeria and applied in various high-density communities in Ibadan and Lagos. Community mobilization was used in the process which has aroused awareness in urban communities and led to improved recycling among communities.
  4. A household biogas digester was developed and was awarded a patent by the Federal Republic of Nigeria.
  5. Conversion of organic wastes into organic and organo-mineral fertilizer; a patent was awarded by the Federal Republic of Nigeria 2006. This is translated into community fertilizer plants in the country:

(i) A 20-ton per day capacity organo-mineal fertilizer plant was designed and built for Bodija market in Ibadan (1998), Nigeria which is the first prototype demonstration project for the country. This has aroused interest all 0ver the country and the Federal Government has recommended for the entire country as a part of “Waste to Wealth Initiative” and as a strategy for “Poverty Alleviation” and Sustainable Development. Based on this, UNDP and UNCHS have engaged my expertise in propagating this technology to 36 States in the country through Workshops. University of Ibadan, Sustainable Ibadan Project and Ibadan Waste Management Authority have bagged National and international merit awards and appreciation. I was the architect of this programme and mobilized a team under “Foundation for Environment and Technology”. Now it is renamed as “Environmental Development Foundation”.

      (ii) A 5-ton per day capacity organo-mineral fertilizer plant was designed and built for Ayeye

community, Ibadan (2002) where sorting of non-biodegradable and biodegradable were practiced and composted.

      (iii) A 5-ton per day capacity food residual conversion to compost (2002) was developed for a

flow station for Shell Petroleum Development Company, Forcados, Delta Sate

(iv) A 15- ton per day capacity Integrated Waste Management Complex was designed and built (2005) for Oyo State Government at Orita-Aperin, Ibadan where an organo-mineral fertilizer plant, a plastic recycling plant and a scrap metal recycling plant were designed and built for management of Solid waste generated in Ibadan.

(v) A 25-ton per day capacity organo-mineral fertilizer plant, a 5-tpn per day plastic recycling plant and a 1-ton per hour metal scrap recycling plant are being built for the Ondo State Government at State capital, Akure, Nigeria (July 2006). It is being operated for three months.

(vi) A 10-ton per day capacity organo-mineral fertilizer plant was designed and installed for Niger State Urban Development Board, Minna (March 2007).

(vii) A 5-10 ton per day capacity organo-mineral fertilizer plant, and one 2.5-ton per day capacity plastic/Nylon recycling plant was designed and being installed for Aleshinloye market, Ibadan (Commissioned in 2010).

  1. Initiated resource reuse and recycling projects for bones, animal blood, crop residues and waste plastics, which are a problem in many urban centers.
  2. Formed a “Heavy Metals Research Group” and initiated researches on lead, Cadmium, Arsenic and also other toxic compounds. This experience is being used in creating awareness among communities.
  3. Initiated solar disinfection for treating domestic water supplies and also “Water for Vending”. This simple strategy of exposing the water on the rooftop to solar radiation is a practicable alternative to various costly methods used in developing countries.
  4. A novel iron removal method was developed for a textile mill in Lagos, which has yielded some good results and saved money for the mill.
  5. For the first time, Waste management for Health Care Facilities was carried out in the country involving 53 Healthcare facilities; the Federal Ministry of Environment is now developing a Policy on the management strategies for such hazardous wastes nation wide.
  6. Initiated Environmental Biotechnology and contributed to the waste treatment, pathogen survival strategies in environment.
  7. Initiated researches on phytoremediation of contaminated soils using sunflower (Helianthus annuus L. and Tithonia diversifolia) which has application on heavy metal contaminated soils around industries (A battery industry and a paint industry were field tested).
  8. Developed Root zone technology for smaller communities to treat their domestic waste waters around the houses. Here, plant species, e.g. Phragmites karaka, Ipomea sp. and Canna lily were used for field trials. A treatment plant is set up for Rolled Steel Company Ltd, Ibadan to treat metal containing effluents.
  9. Designed, built and operated biogas digesters (5 to 13m3 capacity) and trained over 200 EHOs at FUTO, Owerri, Institute of Health Technology, Makarfi, Kwara State University, near Ilorin and University of Ibadan.
  10. Initiated a Smokeless Charcoal Production technology in the Department of Environmental Health Sciences and organized a Hands-on Training programme for staff of Oyo State Ministry of Industry, Applied Science and Technology.
  11. Initiated a ‘Renewable Resources Centre’, in September 2013, a Joint venture between Department of Environmental Health Sciences, Faculty of Public Health and the Teaching and Research Farm, University of Ibadan.
  12. Trained over 200 postgraduate students (at Masters and Doctoral levels) since 1977 and several of them hold key positions in Government, industry, and other national and international agencies.
