Contents
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) assessment pages.
Question
What are the factors that might compromise the acceptance and ecological sustainability of biofuel production from jatropha plant and wastes generated in fish processing industry? Particularly, what are the effects of these activities on the environment and the society, and how do they affect the acceptance among clients and public at large?
Boundaries
- Examine the role of Finland in global bioenergy production.
- The focus is mainly on the production of biodiesel and other liquid fuels used in motorised traffic.
- The impacts to ecology, ethics and are considered but essential health, economical etc. impacts are not ruled out.
Assessed options (scenarios)
- Present state and business as usual. Jatropha and fish waste have no role in Finnish energy production.
- Jatropha and fish waste are used to small extent in energy production.
- Jatropha and fish waste are used to a significant degree in energy production.
Intended use and users
The assessment is of an immediate importance to Neste Oil corporation and other energy production companies in guiding sensible decision making upon future directions in energy production. It is also of significance to all interested people or groups willing to enhance their knowledge regarding biofuel options.
Participants
The principal investigator in the assessments was senior researcher Jouni Tuomisto (MD, PhD) from the Institute of Health and Welfare (Terveyden ja hyvinvoinnin laitos). Neste Oil provided financial support to making of the assessments and participated in the assessment work. The open assessment group consisting of Minttu Hämäläinen, Pauli Ordén, Tiia Sorjonen, Jaakko Örmälä, Matleena Tuomisto, Johannes Kröger, Elina Hirvonen made a significant part of all the assessment work. Vilma Sandström, Teemu Rintala and Mikko Pohjola participated mostly in coordinating the assessments. In addition, 18 stakeholders were invited to participate in the assessment. This was an Open assessment, so anyone was free to participate. The assessment is now over. However, commenting of the content is still possible. You can use the commenting possibility at the end of the page.
Answer
Jatropha
An advantage of the jatropha plant over other oil producing plants is the fact that it can grow in barren soil and can produce a big harvest. Jatropha is poisonous and inedible, unlike corn and palm oil. However, jatropha has not been able to fulfill all expectations. The harvest is highly dependent on irrigation and the nutrient content of the ground. While jatropha can survive in dry barren soil, the oil production remains significantly lower than in irrigated nutritious soil. In areas where cultivable land and water for irrigation limit cultivation, jatropha may compete of land use with food production. It can also have both direct and indirect effects on the ecosystems locally: jatropha cultivation may directly take space from ecosystems or indirectly by causing other activities to take over other still untouched areas. With dispersed and small scale jatropha cultivation logistics becomes a problem, possibly making jatropha cultivation -based businesses to turn out economically infeasible.
The jatropha plant grows in tropical areas, where its cultivation could bring additional revenues and have a positive influence on the development locally. The harvesting of jatropha is still mainly hand work requiring a lot of workforce and thereby may increase the employment locally. Underpayment and seasonal unemployment may turn out problematic.
The oilwaste of fish production
Fish farming industry produces a significant amount of waste annually. The main focus of this assessment was specifically on fish farming. Using this waste in biodiesel production looks like a promising option. The waste coming from fish farming is cheap and does not cause additional emissions. This assessment concentrated on the wastes of the South-East Asian fish farming region, but other regions that could provide sufficiently big amounts of fish waste for the commercial production of biodiesel are not ruled out.
When considering fish waste in biofuel production, other possible uses for the waste must also be taken into account. If heavy waste has to be transported long distances, the transportation may produce greenhouse gases, which may exceed the benefits of using biodiesel. It is also good to take account of the impacts of the waste producing process on the environment and society. On the other hand it could be argued, that fish waste is produced anyway, and its utilization does not influence the impacts of fish farming. However, using of the waste may make fish farming more profitable thus increasing its amount and thus increasing also its local environmental impacts. The environmental impacts of fish farming are highly dependent on what is used as the feed for fish. If they are fed caught fish, it may put pressure on local fish stocks, which are endangered all around the world. Also the untreated waste waters from the farming let out in the waters may cause eutrophication. Fish farming may increase employment locally, but on the other hand can compete for the local resources, such as water and land area, with local food production and other activities.
In common
The goal of the EU and Finland is to use biofuels to reduce the greenhouse gas emissions of traffic and increase the EU's energy self-reliance. In both assessments the raw materials are produced outside the EU, so they would not decrease the EU's dependance on imported oil. However, the assessments did not considered which markets the produced biodiesel would be sold to.
