Question: When considering the use of Jatropha and the residue of fish farming in biofuel production, what are the factors that could diminish the public approval and ecological sustainability? Especially, what are the effects of these activities on the environment and the society, and how do they affect the approval of clients and other people?

Answer: The utilization of the Jatropha plant in biofuel production doesn't seem quite as promising as that of the residue of fish farming. The same problems with direct and indirect changes in the use of landscape and the competition with food production that have come up with the cultivation of other plants used for bioenergy apply to Jatropha as well. The benefit of Jatropha is its ability to grow in harsher environments, but in these conditions the plants oil production decreases. Fish residue is an unavoidable adverse effect of fish farming, and thus the production of the residue doesn't cause any extra emission. Even so, the emissions and effects of fish farming can't be left unnoticed, because the utilization of the residue can also make the primary process more profitable, thus increasing the emissions and effects on the area.

Scope

This page is summary page of The use of Jatropha as a source of bioenergy (in Finnish) and The use of fish farming residue as a source of bioenergy (in Finnish) pages.

Question

When considering the use of Jatropha and the residue of fish farming in biofuel production, what are the factors that could diminish the public approval and ecological sustainability? Especially, what are the effects of these activities on the environment and the society, and how do they affect the approval of clients and other people?

Boundaries

• Examine the role of Finnish people in the production of bioenergy worldwide.
• The focus is especially in the production of biodiesel and other liquid fuels used in the vehicles.
• Of the effects of the activities, the focii are mostly in ecological, ethical and environmental effects, but essentially important health-, monetary- and other effects are not ruled out.

Options under examination (scenarios)

• Present state and business as usual. Jatropha plant and the waste from fish processing are not used in Finnish energy prodution.
• Jatropha and fish processing waste are begun to be used in a small scale in enrgy production.
• Jatropha and fish processing waste are begun to be used in a large scale in bioenergy production.

Assumed use and users

The assessment has an immediate value for Neste Oil and other energy production companies in helping rational paths to be taken in the future. It also has a significance to any interested people or groups, who want to improve their knowledge about choosing biofuels.

Participants

The responsible researcher in the assessment was specialresearcher Jouni Tuomisto (MD) from the Institute of Health and Welfare (Terveyden ja hyvinvoinnin laitos). Neste Oil supported the assessment financially and by participating in the work. As participants were also the open assessment power group: Minttu Hämäläinen, Pauli Ordén, Tiia Sorjonen, Jaakko Örmälä, Matleena Tuomisto, Johannes Kröger, Elina Hirvonen. Included also Vilma Sandström and helping with the leading of the assessments Teemu Rintala and Mikko Pohjola. This was an Open assessment, so anyone was free to participate. The assessment is now over. However, commenting the content is still possible. You can use the commenting possibility at the end of the page.

Answer

Jatropha

As a good side of the jathropa plant compared to other oil producing plants is the fact that it grows in low nitrient grounds and produces a big harvest. Jatropha is poisonous and not edible to people, unlike corn and palm oil. However, jatropha hasn't been able to fulfill all the expectations towards it. The harvest is highly dependent on watering and the nutritiocity of the ground. It does grow in dry and poor grounds, but in these conditions its oil production stays lower than in watered and rich grounds. In areas, where cultivable land and watering water are limiting cultivation, jatropha may compete of land use with food production. It can also have both direct and indirect effects on the ecosystems in the area: planting jatropha may directly take space from ecosystems or cause other actions to start to be taken in still untouched areas. With widely spread and in a small scale grown jatropha logistics develops as a problem, and building a business on jatropha may turn out to be financially unprofitable.

The jatropha plant grows in the tropic, where its cultivation could bring extra profit for the area and effect the development of the area positively. The harvesting of jatropha is mainly hand work, which requires a lot of workforce and increases the employment in the area. Underpayment and season linkedness of the work way come out as problems with labour force.

The oilwaste of fish production

Fish production leaves annually a significant amount of waste. This assessment concentrated specifically in fish farming. Using this waste in the production of biodiesel looks like a promising option. The waste coming from fish farming is cheap and doesn't cause any extra emissions. This assessment concentrates on South-East Asian fish farming area's waste, but doesn't eliminate other areas that could give out big enough amounts of fish waste for the commercial production of biodiesel.

When using fish waste, its other optional accessibilities must be taken into account. If heavy waste has to be delivered long distances, the delivering may produce green house gases, which may exceed the benefits of using biodiesel. It is also good to examine the effects of the waste producing process on the environment and society. On the other hand, it can be stated, that fish waste is produced any way, and utilizing it doesn't effect the effects of fish farming. However, using the waste may make fish farming more profitable thus increasing its amount and thus increasing also its environmental effects in the area. The environmental effects of fish farming are higly dependent on what the fish are fed. If they are fed fished fish, it may put pressure on local fish stock, which are threatened all around the world. Also the untreated wastewaters from the farming let out in the waters may cause eutrophication. Fish farming may increase employment in the area, but on the other hand can compete for the area's recources, such as water and land area, with local food production and other activities.

In common

EU and Finland's goal is to with biofuels reduce green house gas emissions traffic and increase the EU's area's energy self-supportance. In both assessments the raw materials are produced outside EU, so they wouldn't decrease EU's dependance in incomin oil. However, the assessments don't make an opinion about where the produced biodiesel would be sold.
