A Review on the Disposal Methods with Intrinsic Environmental and Economic Impacts of Scrap Tyres in Nigeria

Abstract

The rapid increase in the amount of tyres discarded yearly leads to the problem of scrap tyres littering the country, Nigeria thereby leading to environmental pollution. This paper looks at the extent of the menace scrap tyres has caused, the methods of their disposal and the effects on the environment. The study calls for a concerted effort from researchers, industry operators and regulatory bodies to be up and doing in the disposal of scrap tyres in Nigeria to check the degradation of the environment in its three compartments: air, water and land, with a view to upholding environmental sustainability and embedded economic advantages.

Performance of Adsorbent from Calcium Carbide Residue to Reduce Exhaust Emissions of Two-wheeler

“…Problems occur if the handling of solid waste does not run optimally because it will have an impact on decreasing the quality of the environment and public health. Therefore, efforts and strategies for conservation and recycling of solid waste are needed to save the environment and protect health [1]- [3]. This development also needs to pay attention to the economic aspect.…”

“…The reaction mechanism can be described using the Eq. ( 1) [6]: 𝐶𝑎𝐶 2(𝑠) + 2𝐻 2 𝑂 (𝑙) → 𝐶 2 𝐻 2(𝑔) + 𝐶𝑎(𝑂𝐻) 2(𝑠) (1) It is possible to convert 64 grams of calcium carbide into 74 grams of CCR (Ca(OH)2) and 26 grams of acetylene gas (C2H2), as shown in Eq. (1).…”
