Water is hydro part of the earth (hydrosphere) where a lot of activities that are of biological and economic significance to life take place. This exposes water to pollution by different pollutants such as crude oil, heavy metals and others. There are numerous methods and technologies for separating and removing these pollutants, but they are quite expensive.
A very cheap method of separating these pollutants especially crude oil involved the use of bio-waste (saw dust & egg shell) and waste high density polyethylene (HDPE) bag composite was explored. The composite was produced by extrusion of the high density polyethylene waste reinforced with saw dust and eggshells combined in different ratios using Jombo Extruder Mark 35mm at 250°C, and collected in receiving molds which were allowed to cool before scaling out. The prepared composites were immersed in simulated crude oil spill troughs containing 750g of crude oil of API 40.5 each. The highest percentage of crude oil adsorbed by one of the composites was about 37.0% while the least was about 25.2%. The highest values of crude oil separated from the simulated spill trough was appreciable but more so the preparation of the composites from the constituents used serves as a channel for recycling of wastes.
