One of its uses is as a raw material in the production of palm oil—based biodiesel fuel. The example highlighted some of the major benefits and challenges of developing biofuels. The climate of these two countries is particularly well suited for the growing of palm oil, Hisham Hashim said. There have been attempts to grow palm oil in countries farther north, such as Cambodia, but it is possible only in the southern part of the country because it is too dry farther north.
However, any analysis of the benefits of biofuels needs to include not just its actual use in a vehicle, but also the emissions created during the complete production cycle Palm biodiesel that biofuel.
It also needs to look at the wider economic and social picture surrounding a particular biofuel and its feedstock. I knew I was looking at the future landscape of Central Kalimantan in Indonesia. The Government of Central Kalimantan had just indicated it was going to encourage oil-palm plantations throughout the entire province to supplant the declining forestry sector.
The impacts of the palm oil industry on Southeast Asian and other communities and forests is well documented. It is illogical and immoral that an environmentally friendly fuel be manufactured in Australia using a feedstock that is causing so Palm biodiesel damage elsewhere in the world.
It is estimated that the use of Southeast Asian palm oil as a feedstock for biodiesel will actually increasegreenhouse gas emissions by at least 2 to 8 times more than those saved by using it as a fuel, compared to petroleum-based diesel.
The drained peatlands are also susceptible to long burning fires that emit huge quantities of carbon dioxide.
Drying peatlands also release substantial quantities of methane, a gas with 23 times the global warming impact of CO2. The production of one tonne of palm oil results in approximately 33 tonnes of carbon dioxide emissions.
By comparison the amount of fossil fuel required to generate the same amount of energy results in 3 tonnes of carbon dioxide emissions.
The EU Environment Commissioner announced in January that the EU would introduce a certification scheme for biofuels, and has promised a clampdown on biodiesel from palm oil. But with rising crude oil prices biofuels may become a viable economic alternative.
The inclusion of all imported biofuels in the proposed Carbon Pollution Reduction Scheme, unless the biofuel has originated from a country with a comparable carbon reduction or emissions trading scheme. Immediate removal of tax rebates through the Energy Grants Credit Scheme for all biofuels using palm oil as feedstock, unless it has been independently certified as originating from sustainable sources.
Feedstock production will put further pressure on dwindling water resources The need for more land for feedstock will put pressure on forests and uncleared land. More crops means more fertilisers, which create greenhouse emissions. Feedstock production will compete with food production, leading to higher food prices, as has already happened overseas.
When the feedstock is a by-product of the food production process such as corn stalksthe use of it to produce biofuel removes it from the natural organic cycle, where it is used as nutrient for the new cropand it still needs to be replaced with fertilisers.
The general misconception of biofuel as a clean, green fuel may actually discourage people from making the required changes to their driving habits, and could lead to an increase in fuel use. The large scale use of tallow an animal fat as feedstock for biodiesel, if it leads to a higher number of livestock, needs to be discouraged.
The livestock industry as a whole is responsible for a huge This is mainly due to the production of methane by livestock during digestion, and the breakdown of manure. This brings them into line with Qld. As has been clearly demonstrated in the UK and the US, GM produce can cause major environmental problems, including a contamination of organic produce due to cross pollenation and widespread pollution due to the necessity for massive increases in the use of pesticides for some varieties.
GM crops can also have dangerous and unpredictable effects on insects, animals and humans. Whilst the use of canola for biofuels would lead to reduced local emissions, the introduction of GM varieties is fraught with danger, and should not be supported.Properties of palm oil, palm oil biodiesel and diesel fuel as measured experimentally are presented in Table monstermanfilm.comties of palm oil and palm oil biodiesel are not close to diesel fuel properties, so mixing is the only way to use palm oil or palm oil biodiesel.

The use of palm oil-based biodiesel actually increases greenhouse emissions.

Palm biodiesel is an alternative fuel derived from palm oil and can be used in compression ignition engines, i.e. diesel engines without any modifications. It refers to methyl esters derived from palm oil through a process known as ‘transesterification’.
Palm oil as raw stock. Palm oil is the most prospective biodiesel feedstock compared to other oilseeds. As discussed earlier, palm oil has higher production yield, low fertilizer, water and pesticide needed for the plantation.
