Utilization of Waste Oil in Sand Dune Stabilization to Reduce Environmental Pollution

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.

Application of Petroleum Mulch in Controlling Wind Erosion and Stabilizing Sand Dunes: A Look at Its Environmental Impacts

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.



Keywords:

Environmental impacts, shifting sands, petroleum mulch, wind erosion, sand stabilization



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.

A Review of Research on the Use of Petroleum Mulches for Sand Dune Stabilization


This article reviews research findings on the application of petroleum-based mulches as an effective method for stabilizing shifting sands in Iran’s arid regions. These mulches form a surface layer that prevents wind erosion, conserves soil moisture, and promotes vegetation establishment. The paper highlights the benefits, challenges, and lessons learned from past sand dune stabilization projects using this technique.

Sandy Soils. Report of the Fao-undp Seminar on Reclamation and Management of Sandy Soils in the Near East


This report, part of the 1973 FAO/UNDP Seminar, explores the distribution, properties, and stabilization efforts of sandy soils and sand dunes in Iran. It covers soil classifications, protective measures, and R&D projects such as petroleum mulching, mechanical windbreaks, and plantation of resilient species. Since 1959, Iran has made significant efforts to combat desertification and stabilize moving sand dunes in regions like Ahvaz, Sabzevar, and Qazvin.
Furthermore, in an official FAO report to the Government of Iran in 1971, the use of petroleum mulch was recommended, provided that the mulch layer can retain moisture and remain stable until full seed germination and seedling establishment.

A Review of Mulches to Control Wind Erosion

This paper provides a comprehensive review of mulches used to control wind erosion. The study indicates that crop residues, chemical soil stabilizers, and livestock manure can effectively prevent wind erosion. To be effective, mulches must withstand wind speeds of 38 m/s. Vegetative mulches like wheat straw and prairie hay, when properly anchored to the soil surface, can significantly reduce erosion. Chemical stabilizers such as asphalt and latex emulsions are also effective when applied at sufficient volumes (minimum 3,785 L/ha). Additionally, feedlot manure proves to be a cost-effective mulch for erosion control. However, the high costs of some materials, particularly petroleum-based products, limit their widespread use.

A survey of planting four species of the eucalyptus, based on reserves from precipitation, on mulch covered sandy hills in the Khuzestan province

The vigorous rise in the rate of population growth in the world, mostly in the developing countries, and the limitations on agricultural lands and products call for man to bring about a quest for new resources by the year 2000 in order to meets the various demands. The Khuzestan province is located in the south of Iran, which has an area of sandy plains exceeding 350,000 ha. This is in fact 3.5% of the entire state and 29.5% of the entire agricultural land of Khuzestan. The sand encroachment by wind over the agricultural lands, roads, pipelines and residential areas is a serious economic problem in this area. Sand dunes extend from the northwest to southeast of Ahwaz in the Khuzestan province, in the form of tapes. These include some sporadic expansions consisting of over 68 varieties. The two important sand dunes are those located in Albajy with an extent of about 9,000 ha; and that in the southwest of the Karkheh river of 115,000 ha. Research proves that afforestation offers a permanent solution for the sand dune area problem. Selection of a suitable plant species for this purpose is crucial for successful afforestation. As a result, four eucalyptus species were selected in further investigations. The samples of soil, climate, and ground water were collected and analyzed for several parameters using standard procedures. In this study, petroleum mulch is used for soil conservation, especially preventing wind erosion and also based on reserves of precipitation for plants species such as the eucalyptus. After more than 6 years of cultivating four eucalyptus species, the investigation conclusively demonstrated the Eucalyptus Camaldulensis 9616 as superior (adaptation and growth) to other species in the sand dunes of the Khuzestan province.

Effects of Iranian Petroleum Mulches on Evaporation from Calcareous Soil

This study evaluated the effects of Iranian petroleum mulches (anionic, cationic, and clay emulsions) and the soil conditioner "Krilium Merloam" on evaporation reduction from calcareous soil under greenhouse conditions. Both surface and incorporation applications significantly decreased water evaporation, with the highest reduction (8.8%) observed at 10,000 L/ha (surface) and 0.25% (incorporation). Petroleum mulches formed a semi-impermeable vapor barrier and enhanced soil aggregation, restricting upward water flow. The findings suggest that Iranian petroleum mulches are effective alternatives for soil moisture conservation in arid regions.

A COMPARISON OF PETROLEUM, SAND, AND PINE STRAW MULCHES ON EUCALYPTUS SEEDBEDS

This study compared the effects of three mulches (petroleum, sand, and pine straw) on eucalyptus seedbeds. The petroleum mulch, a water-based petroleum emulsion, outperformed pine straw and native sand in warming the soil and preventing erosion but showed no significant difference in reducing evaporation or nutrient leaching. Applying white sand over the petroleum mulch lowered soil temperatures but proved unstable under rain and irrigation. The findings suggest that petroleum mulch can effectively replace pine straw, while native sand mulch performed poorly.
