Today in Hong Kong, biodiesel is not available for purchase
from petrol stations or marine fuelling pumps. Zenda & Dynamic
provide B2 & B5 Biodiesel distribution services to Hong Kong
clients via barges and tankers. In addition, clean technology
has been applied to assist with fuel storage, contamination and
moisture reduction and eradication, as well as full fuel quality
testing and stabilisation.
As part of their corporate, social and environmental
responsibility, a growing number of Boat and Yacht Clubs are
now using Z-B5 in their ground machinery and committee
boats. For many Club Members, including Hebe Haven
Yacht Club, the waste cooking oil created at the clubhouse is
collected and recycled into the very same Z-B5 biodiesel used,
creating a closed loop from waste to clean fuel.
For many luxury boat hire companies, junk hires, and individual
boat owners the use of Z-B5 or B2 reduces fuel odours and
opacity making a far more pleasant environment for guests. The
reduction in tailpipe emissions contribute to healthier air quality,
and the owners can show they are doing their part to reduce
their carbon footprint at the same time.
Wonder fuel of the future
The biodiesel component acting as a lubricant and cleaner
for engines can improve asset life and overall efficiency levels
further reducing fuel consumption. The use of biodiesel can
help eradicate waste cooking oil from ending back in waterways
or in the human food chain, as well as look after engines.
Pros & Cons of using biodiesel
Pros:
• Reduce harmful emissions
• Provides a cleaner burning and smelling exhaust
• Vastly improves opacity
• Significantly increases lubrication
• Improves cetane levels
• Helps to clean injectors, fuel lines, pumps and tanks
• Safer to store and transport since it has a higher flash
point than regular petroleum diesel
Cons:
• Biodiesel will clean fuel tanks and lines of built-up
residues which will then accumulate in the fuel filter
meaning that you may have to change your fuel
filters more frequently when first using biodiesel
Words Al Fullerton
In this issue Hebe Jebes looks at biodiesel, a cleaner fuel alternative which improves air quality and reduces your
carbon footprint by reusing waste cooking oil.
Diesel emissions in Hong Kong are one of the main sources,
at ground level, of pollutants that continuously cause air quality
to exceed target “safe” levels. Diesel fuel emissions are a huge
contributor to greenhouse gasses including sulfur oxides, carbon
monoxide, nitrous oxides, hydrocarbons, particulates and, like all
fossil fuels, carbon dioxide. What many individuals and corporations
are not aware of is they can reduce their carbon footprint on their
doorstep with the use of Biodiesel blends.
One company in the Hong Kong market is Zenda Green Energy
& partner Dynamic Progress International, which supply biodiesel
blends made entirely from locally supplied, waste cooking oil
from restaurants, hotels and clubs. Biodiesel is referred to as
a B’X’, with the B standing for Biodiesel, and the X denoting
the percentage of biodiesel in the blend. So a B100, would be
100% pure biodiesel, B5 would be 5% biodiesel and 95% Euro V
petroleum diesel.
The recycling of Hong Kong’s waste cooking oil into a clean-burning
biodiesel reduces the amount of waste oil to be recycled back into
the human food chain, as seen in recent gutter oil scandals, and it
also reduces the amount ending up polluting waterways.

So far globally, 64 countries use a mandated blend of Biofuels, Hong
Kong is not yet one of them. Argentina has a mandated B10, Costa
Rica has a B20 biodiesel mandate, numerous American States have
B10 mandated, France uses a B8 blend and NSW State in Australia
enforces a B2. No engine modifications were required and these
blends are fully approved for safe operation in any compressionignition engine designed to be operated on petroleum diesel. This
can include boats, off-road machinery for construction, light-duty and
heavy-duty diesel cars and trucks, tractors and electrical generators.
Biodiesel blends:
B2 Marine Hybrid Blend: This fuel is a blend of 2%
biodiesel as an environmental lubricant to add back
lubricity qualities taken by the removal of sulphur, blended
with Euro V diesel plus a fuel stabiliser and biocide.
Z-B5 5% Biodiesel: Zenda 5% biodiesel (Z-B5) shows a
net reduction in three major engine emissions. CO, CO2
and Particulate Matter compared to regular diesel. This is
also treated with a fuel stabiliser and biocide.
