Plastic drums can be used to store diesel fuel

Before using a plastic drum to store diesel, it is important to check that it is designated as suitable for use as a plastic oil drum. Some plastic drums may be made from other types of plastic that are not compatible with diesel fuel and could contaminate the fuel or break down over time. Even HDPE drums will eventually break down due to the reaction between the diesel and the plastic polymers, so it is important to consider how long you need to store the fuel and follow government guidelines. It is recommended that diesel fuel be stored for no longer than six months.

Another benefit of using plastic drums for diesel storage is that they do not pose the same risks as metal containers. Diesel can degrade quickly if it comes into contact with certain metal alloys, such as zinc or copper. Metal drums can also rust, which can affect the quality of the diesel. Plastic drums are a popular choice for storing diesel fuel because they eliminate these concerns.

When using plastic drums for diesel storage, it is important to follow safety guidelines. Diesel is a flammable liquid, and proper labelling is crucial, especially if the drums are being transported or stored in a location where they could be exposed to extreme heat or temperature changes. These factors can degrade the fuel faster and affect the integrity of the drum. It is also important to consider the colour of the drum, as some colours may be more susceptible to cracking or other types of damage due to temperature fluctuations or exposure to sunlight.

Polyethylene plastic is safe for diesel storage

Polyethylene plastic is one of the most common synthetic materials used in the production of plastic storage drums. It is durable yet malleable, making it suitable for storing and transporting various substances, from food to hazardous waste.

Due to its versatility, many businesses wonder whether polyethylene plastic is suitable for storing diesel fuel. The short answer is yes, it is safe to use polyethylene plastic drums, particularly dedicated plastic oil drums, for diesel storage. However, there are important considerations to keep in mind regarding the duration of storage and potential degradation of the plastic and diesel fuel.

One of the primary benefits of using polyethylene plastic drums for diesel storage is that they do not rust. Metal barrels and storage containers are prone to rust, which can negatively impact the quality of diesel and lead to fuel degradation. Plastic drums, on the other hand, eliminate the risk of rust contamination.

Additionally, diesel fuel can quickly degrade when it comes into contact with certain metal alloys like zinc and copper. With metal drums, there is always a concern about the potential reaction between the metal and diesel. Polyethylene plastic drums remove this uncertainty as they are inert and will not react with the diesel fuel.

However, it is crucial to understand that diesel fuel cannot be stored indefinitely in plastic drums, even those made from HDPE (High-Density Polyethylene). Over time, the diesel will react with the plastic polymers, causing the plastic to break down and leading to potential leakages. Government guidelines recommend that diesel fuel be stored in plastic drums for no longer than six months. After this period, the diesel fuel should be disposed of, and the drum replaced to prevent any issues.

Diesel is less volatile than gasoline

Diesel is a fractional distillate of crude oil. It is heavier and more viscous (thicker) than petrol. Diesel fuel is widely used by every mode of transport—rail, sea, air, and road—across every conceivable industry (excluding the automotive industry). Diesel is denser and less volatile than gasoline. It does not evaporate and is harder to ignite. Gasoline, on the other hand, is highly flammable and ignites easily, such as when a lit match is tossed into a pool of gasoline, causing the vapors above the surface to ignite.

Gasoline engines operate at a specific ratio of fuel and air. At high altitudes, the thinner air requires less fuel to maintain this ratio, which affects performance. In contrast, diesel engines have turbochargers, which pump more air into the combustion chambers at high altitudes, allowing them to perform better in such conditions. Diesel engines are also more efficient than gasoline engines, with a gas engine only reaching about 20% efficiency, while diesel engines can achieve 40% efficiency or higher. This higher efficiency makes diesel a popular choice for heavy vehicles like trucks, where fuel costs can become a significant expense.

While diesel is less volatile than gasoline, it can still react with certain materials over time, such as plastic polymers and particular metal alloys like zinc or copper. This reaction can lead to the breakdown of the plastic or metal, resulting in leakages. Therefore, it is important to use suitable containers, such as industrial-grade plastic drums made from high-density polyethylene (HDPE) or specific metal drums that will not react with the diesel. These containers are designed to safely store hazardous materials like diesel fuel and prevent contamination.

The choice between using plastic or metal drums for diesel storage depends on various factors. Plastic drums have the advantage of not reacting with the diesel fuel, while metal drums can be prone to rust, which can affect fuel quality. Additionally, diesel can degrade quickly when it comes into contact with certain metal alloys. On the other hand, plastic drums have limitations on how long they can safely store diesel fuel. Government guidelines recommend that diesel fuel be stored for no longer than six months, as the diesel can start to break down and become unfit for use.

HDPE plastic is strong enough for hazardous waste

HDPE, or High-Density Polyethylene, is a type of thermoplastic known for its strength and large strength-to-density ratio. It is commonly used in the manufacturing of containers for milk, motor oil, shampoos, conditioners, soap bottles, and other household products. HDPE is also used for storing and transporting hazardous waste.

HDPE is highly resistant to chemicals, making it suitable for hazardous waste storage and transportation. It doesn't react with most acids, bases, and solvents, ensuring that the contents remain safe and uncontaminated. Additionally, HDPE is resistant to UV rays and can withstand a wide range of temperatures, making it suitable for outdoor applications. It does not become brittle in cold weather or degrade in hot conditions.

The durability and weather resistance of HDPE make it a crucial material in the construction industry. It is used in geomembranes, roofing membranes, window frames, and flooring. HDPE is also used in pipes for potable water, wastewater, irrigation systems, and natural gas distribution due to its ability to withstand high pressure and resistance to cracking.

While HDPE is a commonly recycled plastic, it is not biodegradable and can take hundreds of years to decompose in a landfill. However, it can be melted down and reformed into new products without losing its properties, making it an environmentally friendly choice in some respects. Recycling HDPE contributes to a reduction in resource consumption and pollution.
