Dealing with oil spills is not only a reflection of environmental and worker protection awareness but also a legal obligation for businesses. To quickly address oil and grease spills and ensure operational efficiency, organizations must choose specialized oil spill response products.
Here are the top 5 best oil spill response products available today:
1. Oil Absorbent Pads
Oil absorbent pads are essential products for factories, workshops, garages, and production facilities of all sizes. These pads are used to clean and absorb oil spills and leaks on machinery, as well as oil on floors and water surfaces. They can absorb up to 20 times their weight and can be reused multiple times after wringing, making them an efficient and cost-effective solution for businesses.
2. Oil Containment Booms
In the event of large-scale oil spills, there is a high risk of affecting production areas and surrounding environments. This could lead to fines or compensation claims if the incident spreads and causes significant damage. Oil containment booms help quickly and safely isolate the oil, ensuring that the spill is confined to a small area for easier and timely response. Besides preventing the spread of oil, these booms can also absorb oil quickly and can be used both on land and water.
3. Oil Absorbent Rolls
Oil absorbent rolls are very useful for areas with continuous oil leaks or for responding to and handling oil spills in the environment. These rolls can be torn into smaller sections like absorbent pads for flexible use or spread out as a safe walkway in areas with extensive oil spills on floors, beaches, or other surfaces.
4. Cleaning Powder/Oil Absorbent Powder
This is a significant technological advancement in oil spill response worth discussing. Most oil production and storage facilities believe that using sawdust or sand can clean oil-stained floors; however, in reality, sawdust and sand cannot completely clean the surface, leaving an oily residue that causes slipperiness and unsanitary conditions. N-Powder Sorbents oil absorbent powder completely absorbs 100% of the oil on the floor without the need for secondary cleaners, offering an optimal and quick solution for oil spill response. Oil absorbent powder can be used on all hard floors, cement floors, and yards

The “race” to produce green hydrogen in the Asia-Pacific region is heating up as many leading Western energy companies partner with regional counterparts to launch a series of renewable energy projects.
According to Nikkei Asia, Danish corporation Orsted—the world’s largest offshore wind company—and several major Western oil companies are planning to invest in this sector in Asia.
Green hydrogen is produced by using renewable energy from sources like sunlight and wind to split water into hydrogen and oxygen. The hydrogen fuel is then used in heavy industries such as steel production, concrete manufacturing, and transportation.
The global demand for green hydrogen is rising sharply, especially in Europe, where there is a strong push to develop renewable energy to reduce dependence on Russian energy supplies.
However, this investment trend is expected to explode in Asia in the near future. “Initially, we focused on Europe. But we will certainly expand into the Asia region in the near future,” Per Kristensen, President of Orsted Asia-Pacific, told Nikkei Asia.
Last year, Orsted partnered with South Korean steel company POSCO in a wind power project. They plan to produce green hydrogen to support the “hydrogen steel” initiative—using hydrogen instead of coal in steel production. Having completed several green hydrogen projects in the North Sea, Orsted will accelerate investments in renewable energy projects in Asia in the near future.
Meanwhile, major Western oil companies are also flocking to green hydrogen projects in Asia. With over 40% stake, British oil giant BP has become the largest shareholder in the Asian Renewable Energy Hub—a massive green hydrogen project in Australia. With plans to produce up to 1.6 million tons of green hydrogen annually, the British multinational aims to capture 10% of the global renewable fuel market.
American multinational Chevron is collaborating with Indonesia’s state oil company Pertamina and Singapore’s national energy company Keppel to produce green hydrogen from geothermal energy in Southeast Asia. These companies plan to produce 80,000 to 160,000 tons of green hydrogen annually.
China, the world’s largest hydrogen consumer, aims to lead in green hydrogen production. Several large-scale projects have already been launched, including a 20,000-ton-per-year plant funded by Sinopec, the national oil company.
In India, the government plans to expand green hydrogen production to reduce reliance on imported energy and phase out fossil fuels from its economy. This effort is part of a broader goal to achieve net-zero emissions by 2070. The New Delhi government aims to produce 25 million tons of green hydrogen annually by 2047. Meanwhile, national oil companies NTPC, Indian Oil Corp, and several Indian billionaires like Gautam Adani and Mukesh Ambani—who are giants in the coal and oil sectors—have also announced investments in renewable energy, including green hydrogen.
According to a report by the Hydrogen Council, which includes over 150 multinational companies and the U.S. consulting firm McKinsey & Company, the total demand for green hydrogen in China, India, Japan, and South Korea will reach approximately 285 million tons by 2050, accounting for about 43% of the world’s total green hydrogen production.
Oil contamination in wastewater is a common issue in the drainage systems of businesses that use oil in production operations, such as large-scale restaurants and industrial kitchens. When not properly and thoroughly treated, this oil-contaminated wastewater can flow into canals, rivers, or seep into the soil, posing a danger to aquatic life and leading to severe pollution that is difficult to manage. Treating oil in wastewater before releasing it into the environment is not only a matter of awareness but also a legal responsibility for businesses.
How to thoroughly treat oil in wastewater?
1. In cases where oil is regularly present in moderate amounts, with continuous wastewater discharge:
At factories, industrial zones, and production areas where wastewater is consistently contaminated with oil, such as in hydroelectric plants, thermal power plants, and plastic manufacturing plants, implementing an oil filtration solution before discharging wastewater into the environment is essential.
N-FIBER Oil Filter Fabric is designed to filter oil from water, whether it’s surface oil or emulsified oil within the water. This product absorbs and retains oil without absorbing water, allowing water to pass through at a rate of 250m³/hour. The oil filter fabric can be placed at drainage outlets, the beginning of discharge pipes, or in three-chamber septic tanks to completely filter out oil and waste from the wastewater as it flows through. This is a safe, effective, easy-to-use, and applicable oil filtration solution.
2. In cases of oil spills with large, sudden amounts of oil:
In situations where a large amount of oil spills into a water source due to an accident or mishap, the immediate action required is to collect the spilled oil before it becomes emulsified and harder to treat.
N-FIBER Oil Absorbent Pads are ideal for such scenarios. These pads absorb only oil, not water, and do not release the absorbed oil afterward. They are suitable for floating on oil-contaminated water surfaces to collect the spilled oil. The pads can absorb up to 10 times their weight in oil. After using the absorbent pads to collect surface oil, workers can use the oil filter fabric to further filter the water, ensuring that any remaining emulsified oil is removed before the water is discharged or reused.
Where to purchase N-FIBER Oil Absorbent Pads and Oil Filter Fabrics?

Areca leaf sheaths, once considered agricultural waste, have been transformed by BIGNANOTECH into useful products such as bowls, plates, and dishes. These products are widely used in both domestic and international markets.
Recognizing the potential of the abundant areca leaf sheaths in Quang Ngai Province—one of Vietnam’s largest areca-growing regions—we conceived the idea of repurposing this waste. This not only helps increase farmers’ income but also serves as an eco-friendly alternative to plastic waste.
In Quang Ngai, fresh areca nuts are harvested, dried, sorted, packed, and then distributed to local dealers or exported directly to markets in China, India, Taiwan, and beyond. The collection and repurposing of areca leaf sheaths into consumer products provide an additional income stream for areca farmers in Quang Ngai.
After being collected, the areca leaf sheaths are cleaned, soaked to soften, and drained. They are then molded into shape using a heat press, sterilized with UV light, and finally packaged.
Bowls, plates, and dishes made from areca leaf sheaths undergo meticulous craftsmanship before being boxed for sale.
As the world grapples with plastic waste management and searches for sustainable solutions, the use of areca leaf sheath products as an alternative to single-use plastic dishes is emerging as a new market trend. These eco-friendly products are of comparable quality to disposable plastic utensils and similarly priced. Made entirely from natural areca leaf sheaths, they are environmentally friendly and easy to dispose of.
Products can be made in many diverse shapes, images or text can be printed on the product according to customer needs.
Given the global commitment to green practices and environmental protection, products like those made from areca leaf sheaths are gaining international popularity. Currently, areca leaf sheath products are available in South Korea, Canada, Poland, the United States, and have received positive feedback.
Additionally, our areca leaf sheath products have been adopted by a domestic airline for use in their business class service.
Areca leaf sheath bowls and plates are highly affordable, available in various designs to meet consumer demand, reusable, and environmentally friendly, making them a favorite in foreign markets.
Besides areca leaf sheaths, we have also developed a line of bowls and plates made from the leaves of the coastal tra tree. These products are particularly popular in the U.S. market.

In the evolution of electronic devices, silicon has always been dominant. However, with the continuous advancement of Moore’s Law, the physical limitations of silicon-based materials are becoming apparent. Today, we are on the brink of an industrial revolution, with various sectors exploring different materials, notably wide bandgap semiconductors like SiC and GaN. The latest buzz surrounds graphene.
Discovered in 2004 by two professors at the Chernogolovka Institute of Microelectronics at the University of Manchester, graphene has been hailed as a miracle material. Graphene, a two-dimensional material consisting of a single layer of carbon atoms, boasts three remarkable properties:
It is extremely strong, being over 200 times stronger than steel.
It has extremely high carrier mobility.
It possesses very high thermal conductivity, allowing efficient heat dissipation and preventing electronic devices from overheating.
Graphene seems ideal for the electronics industry, but it lacks a bandgap, a crucial property for transistor switching. For the past 20 years, efforts have focused on “opening a gap” in graphene, the primary challenge for commercial applications.
Graphene was discovered in 2004 using Scotch tape on a piece of graphite
Recent research by Professor Walter de Heer’s group at the Georgia Institute of Technology and Professor Ma Lei at Tianjin University has successfully created a bandgap in graphene, unlocking new potential for its application in semiconductors. By imposing specific constraints during growth on SiC, they developed semiconducting epitaxial graphene (SEG) on single-crystal silicon carbide substrates with a bandgap of 0.6 eV and room-temperature mobility exceeding 5000 cm²V⁻¹s⁻¹, ten times that of silicon and twenty times that of other two-dimensional semiconductors. Graphene allows electrons to move through it much faster, akin to driving on a smooth highway versus a gravel road. This breakthrough opens new possibilities for graphene’s application in semiconductors.
Their research was published in the journal Nature on January 3 (Image source: Christopher McEnany/Georgia Institute of Technology)
How is a Bandgap Created in Graphene?
There are two main methods: the nanoribbon approach, where graphene is cut or shaped into ultra-fine nano strips, and the substrate interaction method, which uses the interaction between graphene and its growth substrate to create a bandgap. The former involves complex manufacturing processes and variability among samples, posing challenges for large-scale production. The latter involves selecting specific substrate materials and adjusting growth conditions to alter graphene’s electronic properties.
The method used by Professor Walter de Heer’s team involves the latter approach. They focus on developing a “buffer layer” of graphene on silicon carbide (SiC). As early as 2008, it was known that the buffer graphene layer formed on SiC could be semiconducting, but obtaining wafer-level samples was challenging. They achieved this by heating SiC semiconductor material, causing silicon atoms on the surface to sublime, leaving a carbon-rich layer that recrystallizes into multiple layers with a graphene structure. Some of these layers form covalent bonds with the SiC surface, exhibiting semiconducting properties. However, the disorder in the epitaxial graphene layer formed spontaneously on SiC results in extremely low mobility, only 1 cm²V⁻¹s⁻¹, compared to room-temperature mobilities up to 300 cm²V⁻¹s⁻¹ in other materials.
To address this, the researchers used a near-equilibrium annealing method. By sandwiching two SiC chips together with the silicon face of the upper chip facing the carbon face of the lower chip, they created a controlled environment. In high-purity argon at 1 bar pressure and around 1600°C, they grew atomically flat terraces uniformly covered by a buffer layer, resulting in a chemically, mechanically, and thermally stable SEG network aligned with the SiC substrate. This method allows SEG to be shaped using conventional semiconductor fabrication techniques and seamlessly connect with semimetallic epitaxial graphene, making it suitable for nanoelectronics.
Three stages of epitaxial graphene (SEG) production process
SEG Manufacturing Process:
A graphite crucible filled with two 3.5 mm × 4.5 mm SiC chips is heated by eddy currents in a quartz tube.
The chips are stacked, with the carbon face of the lower chip facing the silicon face of the upper chip. At high temperatures, a slight temperature difference causes material flow, forming large terraces on the seed chip and a uniform SEG film.
The process involves three stages:
Heating the chips to 900°C in vacuum for about 25 minutes to clean the surfaces.
Raising the temperature to 1300°C in 1 bar argon for 25 minutes to form evenly spaced SiC bilayer steps.
Increasing the temperature to 1600°C in 1 bar argon, resulting in “step bunching” and “step flow,” forming large, atomically flat mesas where the SEG buffer layer grows.
Their research achieved significant progress, forming a graphene buffer layer on SiC with a bandgap of about 0.6 electron volts, roughly half that of silicon (1.1 eV) and close to germanium (0.65 eV), much narrower than SiC’s bandgap (3 eV). According to the Georgia Tech blog, it took them 10 years to perfect the material.
The discovery of epitaxial graphene not only expands graphene’s application range but could also trigger a paradigm shift in electronics. However, graphene will likely complement rather than replace silicon. This breakthrough in graphene buffer layers provides new momentum for “beyond silicon” technology, particularly in wide and ultra-wide bandgap semiconductors, such as power electronics for electric vehicles and spacecraft electronics. It also promotes in-depth research into integrating various functional devices like sensors and logic components on SiC, crucial for developing renewable energy and managing unstable inputs.
A spill response kit is the most convenient and optimal solution for handling oil, chemical, and corrosive liquid spills on a medium to small scale. These kits include equipment, tools, and materials designed to control and clean up spilled liquids, allowing businesses or individuals to promptly manage oil or chemical spills in workshops, factories, gas stations, large transport vehicles, and other areas at risk of fuel, oil, chemical, and industrial liquid spills.
Spill response kits typically include components such as:
Safety equipment like boots, gloves, and safety goggles
Absorbent pads: Used to quickly and conveniently absorb liquids.
Absorbent pillows and booms: Used to contain the spill area, prevent contamination spread, and absorb large quantities of spilled liquids.
Specialized cleaning agents: To clean contaminated surfaces.
Brooms and containers: For collecting absorbed waste.
Instruction manual: Provides detailed guidelines on spill response procedures.
2. When to Use a Spill Response Kit?
Small to medium-scale spills or leaks of liquids such as oil and chemicals occur frequently at production facilities, workshops, factories, storage areas, and fuel businesses. Therefore, equipping a spill response kit is crucial to promptly prevent fire hazards, environmental pollution, and health risks. Spill response kits should be placed near high-risk areas to allow personnel to quickly access and deploy them in case of a spill.
3. How to Choose the Right Spill Response Kit?
Currently, there are three types of spill response kits:
Oil Spill Response Kits: Specifically designed for medium to small oil spills at gas stations, factories, industrial areas, etc.
Chemical Spill Response Kits: Optimal for handling high-concentration chemical spills and hazardous chemicals in laboratories, R&D areas, and industrial production zones.
Universal Spill Response Kits: Suitable for responding to oil or chemical spills, such as oil-based solutions, acids, bases, corrosives, chemicals, and unidentified liquid spills in medium to small-scale areas.
Depending on the specific business operations and chemical usage needs, organizations should choose the appropriate spill kit and the necessary materials within the kit to ensure the most effective spill response.
4. Spill Response Kit Usage Instructions
Here are the detailed steps for using a basic spill response kit:
Step 1: Use the safety equipment when responding to an oil or chemical spill.
Step 2: Stop the source of the oil or chemical spill. Use absorbent booms to contain the spread of oil and chemicals to neighboring areas.
Step 3: Place absorbent pads and pillows over the entire spill area to absorb and recover all liquid from the surface.
Step 4: Apply cleaning powder to the spill area to absorb any remaining liquid adhering to the surface. Then, use brooms or stiff brushes to scrub the surface thoroughly.
Step 5: After handling the spill, collect the used equipment and tools for reuse. Place the absorbed chemical products in hazardous waste storage, away from heat sources, water storage areas, and avoid disposing of them directly into the environment to prevent cross-contamination.
