Kalantuotanto aiheuttaa vuosittain merkittävät määrät jätettä. Tässä arvioinnissa keskityttiin nimenomaan kalankasvatukseen. Näiden jätteiden hyödyntäminen biodieselin valmistuksessa näyttää lupaavalta vaihtoehdolta. Kalankasvatuksen sivuvirtana syntyvä jäte on halpaa, eikä sen tuotanto aiheuta lisäpäästöjä. Tässä arvioinnissa keskityttiin erityisesti Kaakkois-Aasian kalankasvatusalueen jätteisiin, muttei rajattu pois muita mahdollisia alueita jotka voisivat tarjota tarpeeksi suuria määriä kalajätettä biodieselin kaupalliseen tuotantoon.

Kalajätteen käytön kanssa täytyy ottaa huomioon jätteen muut vaihtoehtoiset käyttömuodot. Jos painavaa jätettä joudutaan kuljettamaan pitkiä matkoja, voi kuljetus aiheuttaa kasvihuonekaasuja, jotka saattavat ylittää käytöstä aiheutuvat hyödyt. Jätteen käytön kohdalla on hyvä myös tarkastella jätettä tuottavan prosessin ympäristö- ja sosiaalisia vaikutuksia, tässä tapauksessa kalankasvatuksen vaikutuksia ympäristöön ja yhteiskuntaan. Toisaalta voidaan argumentoida, että kalajätettä syntyy joka tapauksessa, eikä sen hyödyntäminen vaikuta kalankasvatuksen vaikutuksiin. Jätteen hyödyntäminen saattaa kuitenkin tehdä kalankasvatuksesta kannattavampaa ja lisätä sen määrää ja näin ollen myös ympäristövaikutuksia alueella. Kalankasvatuksen ympäristövaikutukset riippuvat suuresti siitä, minkälaista ravintoa kaloille syötetään. Mikäli kaloille syötetään kalastettua kalaa voi tämä aiheuttaa painetta alueen kalakannoille, jotka ovat uhattuina ympäri maailmaa. Myös kasvatuslaitosten käsittelemättömät jätevedet voivat aiheuttaa alueen vesistöjen rehevöitymistä. Kalankasvatus voi lisätä alueen työllisyyttä, mutta toisaalta se voi kilpailla alueen resursseista, kuten vedestä ja maa-alasta paikallisen ruoantuotannon ja muun toiminnan kanssa.

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.

EU:n ja Suomen tavoitteena on biopolttoaineiden kautta vähentää liikenteen aiheuttamia kasvihuonekaasupäästöjä sekä lisätä EU:n alueen energiaomavaraisuutta. Molemmat arvioinnissa käsitellyt raaka-aineet tuotetaan unionin ulkopuolella, joten EU:n alueella käytettynä ne eivät vähentäisi tuontiöljyriippuvuutta. Arvioinneissa ei kuitenkaan tarkemmin otettu kantaa siihen, mihin tuotettu biodiesel markkinoitaisiin.

Main message
Question: When considering the use of Jatropa and the residue of fish production 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 Jatropa plant in the production of biofuel 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 Jatropa as well. The benefit of Jatropa is it's ability to grow in harsher environments, but in these conditions the plant's oil production decreases. Fish residue is an unavoidable adverse effect of fish farming, and thus the production of the waste doesn't actually 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 Jatropa 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 Jatropa and the residue of fish production 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. Jatroph it poisonous and doesn't work as human food, 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 jatrohpa 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.
