Abstract
Improper disposal and burning of agricultural residues are commonly practiced in some developing countries in which harmful gaseous products released into the atmosphere and some are depleted and reacted with the soil causing environmental pollution. Renewable technology can therefore be introduced for the utilization of the residues and ensure proper storage medium of the residues. An investigation was carried out on the pollution potential of oil palm residues on surface and underground water resources at the processing centre. Oil palm residues and water samples from the stream and well located near the oil processing site were used for the experiment. Water samples were collected during the raining and dry season to determine the level of pollution caused by the residues. Physical, chemical and bacteriological parameters of the water samples were determined. The chemical compounds of the palm residues were investigated. Results showed that aromatics compounds are mainly dominant of the palm fruit fiber which was characterized for bio-fuel production. It is revealed that effect of pollution on water bodies is significant at p<0.05. Hence, results showed that some parameters like colour, total solids, pH, amine contents, Escherichia coli exceeded World Health Organization (WHO) levels for drinking water. The amine content with (0.35 mg/L) of the samples was higher than the level recommended (0.1 mg/L) for drinking. For colour, the least value of 15.5 mg/l of the total samples was higher than the recommended value (15.0 mg/L). Also, the values of E. coli which ranged between 0.03-0.15 were far above zero count/100ml of World Health Organization (WHO) maximum permissible level for drinking water. Therefore, oil palm waste should be properly disposed and ensure improved storage of the residues for further processing. Conversion of the residues to useful products through renewable technology will alleviate environmental pollution. Key words: Residues, climate change, pollution effect, renewable technology.
Highlights
Climate change refers to as a change of climate which is directly or indirectly attributed to human activity that affects the composition of the global atmosphere, while climate change includes global warming and everything else that will be affected by increasing greenhouse gas (GHG) levels (UNFCCC, 1994)
This study investigates the effect of residues disposal on surface and underground water and employed renewable technology for the purpose of converting waste to energy and greatly contribute to global climate change mitigation
The liquid extracts were acidic in nature because it turned blue litmus paper to red
Summary
Climate change refers to as a change of climate which is directly or indirectly attributed to human activity that affects the composition of the global atmosphere, while climate change includes global warming and everything else that will be affected by increasing greenhouse gas (GHG) levels (UNFCCC, 1994). The level of these GHGs has increased beyond natural level Awosika et al, 1992). This has environmental implications as stated by Jekayinfa and Omisakin (2005) that pollution rate will be increasing if the residues are not utilized
