INGENIEUR Waste of Positive Value Waste of Negative Value Table 2 Some types of papers, plastics, recyclable metals, industrial e-waste, glass, selected green waste, etc. Food waste, household e-waste, batteries, non-recyclable metals, used beverage cartons (UBC), disposable diapers, fluorescent lamps, construction wastes, other household hazardous waste etc. Note: Glass and green waste could also be negative value; and UBC could be positive value subject to logistic and other factors returns while the responsibilities on other wastes that carry negative value are neglected. In reality, about 80% of our total wastes generated require additional costs to deal with it instead of generating wealth out of it. More worrying in the long run, the WtW concept might cause unwillingness to pay for proper waste management because people might have the mindset that if waste is making wealth, why should they pay for it? Are We Focusing on the Right Issues? While the Government has started to ban the use of plastic straws, it is not unreasonable because it is a world trend and many countries have banned single use plastic straw, especially after a video circulating showing a straw stuck in a turtle’s nose. Nevertheless, is banning straw the only thing we need to do? Do we have any unsolved but more serious problems? Some other waste generated in Malaysia are shown below. Types of waste Pieces per year Fluorescent lamps 70,000,000 Phone lithium batteries 131,700,000 Disposable diapers 4,140,058,125 Plastic straws 10,930,000,000 Cigarette butts 14,125,000,000 While over 14 billion pieces of cigarette butts are mainly littered on the streets and could also pose a major source for ocean plastics, it is unfortunate but a reality that 100% or more than four billion disposal diapers are dumped into the landfill sites in the country. These diapers are all made of plastics, which will stay there underneath the land for hundreds of years. What is the difference between cigarette butts, disposable diapers and plastic straws? Well, cigarette butts and diapers did not go into the nostril of turtles! Worst still, there is no system in place for fluorescent lamps’ collection and disposal in Malaysia, thus nearly all are also being disposed at the landfill sites except for lamps from some industries that are disposed to dedicated treatment facilities along with other scheduled waste that they have generated. Fluorescent lamps contain mercury, and 70 million pieces of them could release about 500kg of mercury into our environment throughout the country. It is undeniable that the number of fluorescent lamps used could be less now, being replaced by LED lamps. However, literatures show that some LED lamps might contain arsenic, which is also a highly hazardous substance that should be strictly controlled in terms of its disposal. The environmental and health impacts from mercury or arsenic are probably thousands of time more severe than plastic straws but we still have no strategy to deal with it. Unfortunately, it does not mean the problem does not exist. We have yet to have proper frameworks or strategies to address these problems, which so far are not even highlighted and they remain as problems pushed under the carpet. Why is that so? It is mainly because these problems are not wealth generating and they require significant costs to deal with it. For example, florescent lamps, classified as under mercury-contained waste, cost of disposal could be more than RM3,000 per tonne. There is no legal system in place and thus, no one has obligation to bear the costs for proper treatment and disposal. As long as a system is not in place, even the fluorescent lamps generated from Government buildings are possibly all disposed to the landfill sites. Government’s intervention to have a holistic approach in managing all problematic waste in the country is much needed, with the necessary 8 VOL 82 APRIL-JUNE 2020
