Oil drilling operations produce substantial amounts of waste, including drilling mud and heavy petroleum residues, which pose a serious threat to the environment. This study explores the reuse of such waste oils as mulch for stabilizing shifting sand dunes. This approach not only offers an effective means to reduce environmental pollution but also helps in controlling wind erosion and dust storms in arid regions. The economic analysis suggests that recycling waste oil in this way is more cost-effective than burning or burying it. The paper concludes with practical recommendations for implementing this solution as an environmentally friendly alternative in desert management.

Abstract:

One of the major challenges in Iran’s arid and desert regions is the control of moving sand dunes. The use of petroleum mulch, either alone or in combination with other biological or mechanical methods, can be effective in reducing wind erosion and stabilizing mobile sands. Petroleum mulch refers to by-products of heavy petroleum derivatives that are applied to the soil surface to prevent erosion and fix shifting sands. Although the process of mulching is complex and costly, its results in sand stabilization have been satisfactory. Despite the widespread use of petroleum mulch and its observed impact on vegetation, comprehensive environmental studies on its effects are still lacking. This paper aims to explore not only the application of petroleum mulch in wind erosion control and sand stabilization but also to evaluate its environmental impacts.

1. Introduction

Wind erosion and the movement of sand dunes are critical environmental issues that not only degrade agricultural lands but also negatively affect air and water quality. Therefore, applying effective methods to manage this phenomenon is essential.

⸻

2. Petroleum Mulch

Petroleum mulch, as a protective material, can form a barrier over the soil surface, preventing degradation and erosion. This paper examines the mechanisms through which petroleum mulch functions to stabilize the soil and reduce wind erosion.

⸻

3. Environmental Impacts

Alongside its practical benefits, the environmental consequences of petroleum mulch must be considered. Potential pollution, effects on local ecosystems, and the impact on groundwater quality are among the concerns reviewed in this paper.

⸻

4. Conclusion

Petroleum mulch proves to be an effective solution for controlling wind erosion and stabilizing sand dunes. However, its environmental aspects must be carefully assessed to prevent potential negative impacts. This paper seeks to offer strategies for optimizing its use in alignment with environmental conservation.
