Biodiesel

What is Biodesel?

Biodiesel is a biologically based diesel fuel , made from oils and fats. This is a green fuel and can be used as a substitute for fossil diesel, or blended with diesel in diesel engines without modification. It has lower emission of air pollutants and biodegrable in the environment.

 

Biodiesel (B100) quality is governed by ASTM D 6751 or EN 14214 quality parameters. Our fuel meets both American (ASTM D6751) the European Committee for Standardization standard . It is certified by independent auditors according to the EU's International Sustainability and Carbon Certification scheme.

 

We supply Pure Biodiesel (B100), Diesel B5 and Diesel B10. Our biodiesel is slightly yellowish and applicable on transportation companies, distribution companies, construction companies and corporate customers using diesel engines. During the past four years, our biodiesel product gives 100% the same power and mileage as fossil diesel which is approved

 

Some of the Diesel B5 and Diesel EN590 properties are summarized below, and they are giving the same power to the diesel engines.

Why use Biodesel?

The smartest technologies deliver benefits to multiple interests, including improved economy, and a positive impact on the environment and governmental policies.

 

Biodiesel is one of several alternative fuels designed to extend the usefulness of petroleum, and the longevity and cleanliness of diesel engines. The role of the biodiesel industry is not to replace petroleum diesel, but to help create a balanced energy policy with the most benefit to the Hong Kong.

 

Economic Expansion

Money stay in Communities as its production and resources are from local instead of buying from foreign oil producers.

Increased tax base from biodiesel production operations. Decreased the Jobless rate as Jobs created in recycling and operation process.

 

Emissions Reduction

Studies on biodiesel emissions have been conducted for almost 20 years. Below study examined the impact of hundreds of regulated and non-regulated exhaust emissions, as well as the potential health effects of these emissions. Some of these results are summarized below.

Average Exhaust Emissions for 100% Biodiesel Compared to Petroleum Diesel Fuel

Regulated Exhaust Emissions B100

Particulate Matter -47%
Carbon Monoxide -48%
Total Unburned Hydrocarbons -67
Nitrogen Oxides +/- 5 to 10%
Non Regulated Emissions  
Sulfates -100%
Polycyclic Aromatic Hydrocarbons (PAH) -80%
Nitrated Polycyclic Aromatic Hydrocarbons (nPAH) -90%
Speciated Hydrocarbons Ozone Forming Potential -50%

Cycle and Reduction of CO2

Biodiesel helps reduce the risk of global warming by reducing net carbon emissions to the atmosphere. Carbon dioxide will be release to the atmosphere during buring of biodiesel, but crops which are used to produce biodiesel take up carbon dioxide from the atmosphere in their growth cycle. A study conducted and determined that biodiesel reduces net carbon dioxide emissions to the atmosphere by 78.5% compared with petroleum diesel fuel.

The Usage and apply

Biodiesel is known as B100, it can blend and use in many different concentrations and the number following the 'B' stands for the percentage of biodiesel in the fuel.

 

Normally, there are B100 (pure biodiesel), B20 (20% biodiesel, 80% petroleum diesel), B5 (5% biodiesel, 95% petroleum diesel) and B2 (2% biodiesel, 98% petroleum diesel) in the worldwide market.

 

All diesel engines and vehicles can use biodiesel or biodiesel blends directly. It does not require modifications to a diesel engine to be used, expect the older vehicles built before 1993 may require replacement of fuel lines which contain natural rubber.
