Forecasting the volatility of biofuel feedstock prices: the US evidence
2019
Given that, nowadays, 40% of the US corn crop is used for biofuel production, there is a growing concern that the rise in biofuel production might lead to an increase in food prices. However, it is also obvious that significant growth in biofuel use has minimized the demand for fossil fuel and has hence reduced the volume of carbon emissions. It is therefore crucial to model corn market volatility precisely because such an estimate could play a vital role in stabilizing food and biofuel market prices. For this purpose, we consider using the information content of the corn implied volatility (CIV) index to predict the corn futures market return volatility. Using symmetric and asymmetric GARC…
European Union legislation on macroalgae products
2021
AbstractMacroalgae-based products are increasing in demand also in Europe. In the European Union, each category of macroalgae-based products is regulated separately. We discuss EU legislation, including the law on medicinal products, foods including food supplements and food additives, feed and feed additives, cosmetics, packaging materials, fertilizers and biostimulants, as well as biofuels. Product safety and consumer protection are the priorities with any new products. Macroalgae products can be sold as traditional herbal medicines. The novel food regulation applies to macroalgae foods that have not previously been used as food, and organic macroalgae are a specific regulatory category. …
Landowners’ willingness to promote bioenergy production on wasteland − future impact on land use of cutaway peatlands
2017
Landowners are the key players in bioenergy production on wasteland; such as cutaway peatlands. In this study, the landowner's interest to use cutaway peatlands for bioenergy production was investigated using a survey and GIS (Geographic Information Systems) methods in an area in South Ostrobothnia, Finland. The focus was to identify which different bioenergy production chains are preferred by the respondents: combustion, gasification or biogas production from agriculture, energy-willow short-rotation forestry or forestry based energy crops. Also, the influence of personal environmental values on the selection was measured and the future impacts and barriers for the land use were assessed. …

Biogas production from energy crops and crop residues
2006
Energiantuotantoa varten viljellyt energiakasvit ja erilaiset kasvintuotannon sivutuotteet ja jätteet eli peltobiomassat tarjoavat puhtaan ja kotimaisen uusiutuvan energialähteen. Kasvibiomassa voidaan hyödyntää energiana useilla eri tavoilla, joista yksi on biokaasun tuotanto. Biokaasua voidaan hyödyntää lämmön- ja sähköntuotannossa tai liikenteen polttoaineena fossiilisten polttoaineiden sijasta.Annimari Lehtomäki tutki mahdollisuuksia hyödyntää energiakasveja ja kasvijätteitä biokaasun tuotannossa pohjoisissa oloissa. Tutkimuksessa kartoitettiin Suomen oloissa menestyviä, biokaasun tuotantoon mahdollisesti soveltuvia kasvilajeja, sekä määritettiin niiden kemiallinen koostumus ja biokaasu…
