Hi Sanko, that's easy. There are Environmental and Safety departments in many oil firms like NNPC, Shell, etc, and even some private sector organizations. For instance, you can check the internet for NGOs that are focused on the Environment, u'll find something. Ur job is to preserve our environment, and preserve nature. Even the Ministry or organizations that deal with Waste Management exist. Check the net. Perhaps later while you check, some other housemate may remember an organization that will be useful to you. Cheer up!!!
