Pet bottle, A Lagos lagoon menace by Olusegun Ariyo

                                                                                     

Lagos state, the state of aquatic splendor is the second most populated state just after Kano in Nigeria. An aquatic splendor in that, it is almost drown in water, which exists as creeks, lagoons and estuaries-which removes more than 800 square kilometers of the total land area. Water bodies are so prevalent that they have many entry points and tributaries to the sea from upland.




 The importance of these water bodies as a lifeline to the state cannot be overemphasized; because, it helps to regulate the state climate, provides jobs for fishermen, water for farming and domestic use, a transport super highway linking many areas and space for waste disposal. The Lagos lagoon has for long erroneously served as a respiratory of waste however, with the increase in the state population, the ability of the lagoon to continually flush away such waste naturally is becoming reduced.

 This is most especially true with the non- biodegradable wastes which majorly consist of metals, glass, polythene bags and plastic- which has become a visible waste of late on Lagos lagoon. Plastics on its own are notorious for it unsightly presence on water as it cannot sink unlike the other class of wastes when they find their way into water from inland sources. Unsuspecting aquatic lives are known to have been killed by plastics, whales and dolphins are known to be suffocated by plastics when they ingest them, seabirds and seals have frequently been found entangled and strangled by discarded plastics.


The word plastic covers a wide range of materials, which have in common the ability to deform almost immediately and indefinitely under heat and pressure without breaking. Some plastics, like cellophane film and rayon, are based on plant cellulose, a renewable resource. The majority, however, including polythenes and PVC, are based on renewable oil and other hydrocarbons. It has been estimated that, over a quarter of all plastics we use in the world go into short life packaging, and almost none of them are recycled, even though the technology exists to recycle most plastics. Plastic waste makes up between 5 and 7 percent of domestic rubbish, 900,000 of it each year. One of the most environmental challenges connected with the indiscriminate use of plastic is that most do not rot when left in the environment. Of all the plastics, PET bottles are common in waste second after polythene bags. This is because; they are relatively cheap to produce as a means of packaging as compared to other forms of plastics. PET; an acronym for Polyethylene Terephthalate is used to package consumables-especially drinks.

What started as a solution to the cost and safety concern associated with glass bottles is continually becoming a nightmare to the environment and environmentalist at large. The environmental hazards and scares PET bottles leave behind is tasking long after the content of the bottles has been consumed. PET bottles have an environmental, human health and aesthetic challenge; it is found in virtually on all lagoon surfaces in Lagos state, not only in densely populated regions, but also in remote areas far from the obvious sources of human contact. It poses a complex and multi-dimensional challenge with significant implications for aquatic environment and human activities all over Lagos state.


 These impact are both cultural and deeply rooted primarily in poor practices of solid waste management, a lack of infrastructure, various human activities, an inadequate understanding on the part of the public of the potential consequences of their actions, the lack of adequate legal and enforcement system and a lack of financial resources to cope with this challenge.  Although, the environmental costs are often factored into these bottles, however, Nigeria is not doing much as pertains PET bottles clean-up. Few years ago, concern was raised on the menace of “pure water” sachets in Lagos state, debates were held, roundtable discussion arranged on how to clean them up this malaise, after much said and done, the issue was swept under the carpet like other pressing environmental issues in Nigeria.



 Every keen observer will know that, Nigeria as a nation is fast at ratifying and appending to many conventions, protocols and conferences without considering how adequately we can implement such to letter. On the environmental front, The United Nations law of the Sea, the UNEP global initiative on marine litter, Basel convention of 1992, London convention and protocol of 1996, MARPOL convention 73/78, the Earth Summit and the Sustainable Development Conference are all proof to this.  One does not need a soothsayer to tell that Lagos lagoon is continuously been abused, we all need to take an equivocal steps at seeing that PET bottles are controlled so as to reduce their environmental menace to the state.


 Unlike plastics that are difficult to recycle because they do not mix easily, PET bottles are exceptionally recyclable. They can be melted down and regenerated into cotton fiber used in jackets insulation, pillow stuffing, and car interiors or ultimately, they can be molded into bottles again. In the United States, PET bottles’ recycling is a hundred-million-dollar a year business. For example, in the United States, Image Carpet changed from nylon and polyester to PET because of its consistent high quality, the end result was that, they made a huge success in terms of sales by including it in their marketing strategy. Considering these inherent benefits in PET bottles, recycling them is a big business and Nigeria can tap into the available technology employed all over the world.



It needs to be recognized at all levels-individuals, community and nationally-that PET bottles can be recycled. Connected to this, is that waste must be properly disposed; packaging should protect and appeal, yet use minimal resources and be possible to recycle. We need to be aware that PET doesn’t just disappear when we dispose them improperly; it is we who pay-both in money and environmental damage. People must be encouraged to sort waste in Lagos state, we need to think about re-using PET bottles, and the government should consider introducing a small levy on each container to fund recycling projects.



 In addition, there needs to be a guarantee market, with fixed minimum price for different PET bottles. All these should be done in full realization that we don’t have another planet to stay other than this, that if lagosians abuse the Lagos lagoon, they invariably abuse themselves since, their very existence and destiny is tied to the lagoon.
