Environmental scientist, Mr. Ayodele Awe, has said that Lagos metropolis generates about 9,000 tons of waste daily thereby creating enormous challenges for relevant authorities as they try to cope. He spoke on “waste to wealth, the concept of recycling” during the JETS DAY 2011 organized by Corona Secondary School Agbara.
He disclosed that at present only 18% of the waste is recycled while there are plans to recycle about 35% by next year. The poor waste management capabilities of the various levels of government, according to him, is “due to our low level of technological development and poor infrastructural facilities”
Mr.Awe who is a staff of Nestle Nigeria Plc told the students that “waste management has become an important part of public administration because of the increasing growth in population of many cities”.
The benefits of recycling wastes include conservation of resources and cleanliness of the environment through reduction of gabbage.
Mr. Awe said that metals and papers are among materials that can be recycled. At present metals are the most recycled materials because of its cost. The process of recycling steel cans and scraps include treating it with chemicals to make it pure again.
Aluminum can also be melted so that it can be recycled. To recycle paper, it must first be shredded. According to him, the benefit of recycling, is so much to the extent that each ton of recycled paper saves about 17 trees With regards to glass, he disclosed that only bottles glass can be melted and made into new glass.
However, different colors of glass must be separated before being recycled. Only three types of plastic can be recycled out of the seven types of plastics in existence. However, the three types of plastics must be separated before they can be recycled.
The environment scientists also said that hazardous waste, like cleaning fluids, engine oil, nuclear waste are dangerous and expensive to recycle. He mentioned three problems confronting waste management in Lagos.
